doc: fix sysfs ABI documentation
In 4.9 kernel, the sysfs files for Hyper-V VMBus changed name but
the documentation files were not updated. The current sysfs file
names are /sys/bus/vmbus/devices/<UUID>/...

1st round of IIO new device support, features and cleanup for the 4.18 cycle
A nice mix this time of excellent cleanups (many to send drivers
speeding toward staging graduations) and new drivers / device support.
A good part of this is Brian Masney's never ending task on the tsl2x7x
driver. The end is in sight so hopefully we'll get that one out of
staging very soon!
New device support
* AD5686
- Support AD5685R (was wrongly present as AD5685)
- Support AD5672R, AD5676, AD5676, AD5684R and AD5686R 4 and 8 channel
SPI DACs with various precisions.
- Support AD5671R, AD5675R, AD5694, AD5694R, AD5695R, AD5696 and AD5696R
I2C DACs with various percisions and numbers of channels.
* Analog front end rescale driver - New driver.
- Support current sensing usings a shunt resistor.
- Support simple voltage dividers.
- support simple current sense amplifiers.
* TI dac5571
- New driver and device bindings supporting:
dac5571, dac6571, dac7571, dac5574, dac6574, dac7574,
dac5573, dac6573 and dac7573
* Meson-adc
- Support for Meson AXG with DT bindings.
* mpu6050
- Support the mpu9255 which only requires additional WHOAMI entry and
compatible string.
* st_lsm6dsx
- Support for lsm330dlc combinded accelerometer and gyro sensors with
DT bindings.
* stm32_adc
- Add support for STM32MP1 with bindings.
Staging graduations
* adis16201 after some excelent cleanup by Himanshu Jha.
* adis16029 after some excelent cleanup by Shreeya Patel.
New features:
* ABI docs
- Add core ABI docs for angle channels.
* inv_mpu6050
- Provide support for the full range of interrupts the device
supports.
* st_accel
- Add SMO8840 ACPI ID seen in the wild on some Lenovo machines.
* stx104
- Provide a multiple gpio get function.
Cleanups / Minor fixes
* core
- Use new nested structure support to improve kernel-doc.
* ad2s1200
- Use be16_to_cpup instead of opencoding.
* ad5686
- Indentation tidy up.
- Switch to SPDX
- Refactor to allow various numbers of channels.
- Refactor to separate core and SPI specific support, prior to
addition of i2c equivalent devices.
* ad7606
- Use drvdata directly from device rather than boucing via the
platform_device structure.
* ad7746
- Replace opencoded byte swapped i2c calls with _swapped variants.
- White space and line break readability improvements.
- Reorder includes and variable declarations where appropriate.
* ad7791
- Changes to the AD ADC library used by this driver took in the
sampling frequency. This lead to be the wrong path being the one
tied to the resulting attribute, so it didn't work, and a warning
to be printed.
* ad7780
- Remove apparent support for sampling frequency control on devices
that don't support changing the sampling attributes.

media: update/fix my e-mail on some places
There are two places pointing to an unexisting "m.chehab@kernel.org" email. I never had such email, so, I'm unsure how it ends there. Anyway, it is plain wrong. While here, use my canonical e-mail on a bunch of places that are pointing to another e-mail. The idea is that, from now on, all places will be pointing to the same SMTP server.

Add the sysfs file for the new vulerability. It does not do much except show the words 'Vulnerable' for recent x86 cores.

rpmsg: Add driver_override device attribute for rpmsg_device
This patch adds "driver_override" device attribute for rpmsg_device which will allow users to explicitly specify the rpmsg_driver to be used via sysfs entry. The "driver_override" device attribute implemented here is very similar to "driver_override" implemented for platform, pci, and amba bus types. One important use-case of "driver_override" device attribute is to force use of rpmsg_chrdev driver for certain rpmsg_device instances.

power: supply: Add 'usb_type' property and supporting code
This commit adds the 'usb_type' property to represent USB supplies which can report a number of different types based on a connection event. Examples of this already exist in drivers whereby the existing 'type' property is updated, based on an event, to represent what was connected (e.g. USB, USB_DCP, USB_ACA, ...). Current implementations however don't show all supported connectable types, so this knowledge has to be exlicitly known for each driver that supports this. The 'usb_type' property is intended to fill this void and show users all possible USB types supported by a driver. The property, when read, shows all available types for the driver, and the one currently chosen is highlighted/bracketed. It is expected that the 'type' property would then just show the top-level type 'USB', and this would be static. Currently the 'usb_type' enum contains all of the USB variant types that exist for the 'type' enum at this time, and in addition has SDP and PPS types. The mirroring is intentional so as to not impact existing usage of the 'type' property.

Documentation sysfs-bus-usb: Add rx_lanes and tx_lanes introduced in USB 3.2
rx_lanes and tx_lanes sysfs entries show the number of lanes in use by a device. USB 3.2 adds support for Dual-lane (symmetrical), using 2 rx lanes and 2 tx lanes for normal non Inter-Chip SSIC devices. USB 3.1 and older are all single lane. SSIC devices can have up to 4 lanes per direction in use, with different number of rx and tx lanes.

Merge branch 'mm-rst' into docs-next
Mike Rapoport says: These patches convert files in Documentation/vm to ReST format, add an initial index and link it to the top level documentation. There are no contents changes in the documentation, except few spelling fixes. The relatively large diffstat stems from the indentation and paragraph wrapping changes. I've tried to keep the formatting as consistent as possible, but I could miss some places that needed markup and add some markup where it was not necessary.

Char/Misc patches for 4.17-rc1
Here is the big set of char/misc driver patches for 4.17-rc1.
There are a lot of little things in here, nothing huge, but all
important to the different hardware types involved:
- thunderbolt driver updates
- parport updates (people still care...)
- nvmem driver updates
- mei updates (as always)
- hwtracing driver updates
- hyperv driver updates
- extcon driver updates
- and a handfull of even smaller driver subsystem and individual
driver updates
All of these have been in linux-next with no reported issues.

Staging/IIO patches for 4.17-rc1
Here is the big set of Staging/IIO driver patches for 4.17-rc1. It is a lot, over 500 changes, but not huge by previous kernel release standards. We deleted more lines than we added again (27k added vs. 91k remvoed), thanks to finally being able to delete the IRDA drivers and networking code. We also deleted the ccree crypto driver, but that's coming back in through the crypto tree to you, in a much cleaned-up form. Added this round is at lot of "mt7621" device support, which is for an embedded device that Neil Brown cares about, and of course a handful of new IIO drivers as well. And finally, the fsl-mc core code moved out of the staging tree to the "real" part of the kernel, which is nice to see happen as well.

Pant.
- The trace documentation has been converted to RST by Changbin Du
- I thrashed up kernel-doc to deal with a parsing issue and to try to make

IMA: Support using new creds in appraisal policy
The existing BPRM_CHECK functionality in IMA validates against the credentials of the existing process, not any new credentials that the child process may transition to. Add an additional CREDS_CHECK target and refactor IMA to pass the appropriate creds structure. In ima_bprm_check(), check with both the existing process credentials and the credentials that will be committed when the new process is started. This will not change behaviour unless the system policy is extended to include CREDS_CHECK targets - BPRM_CHECK will continue to check the same credentials that it did previously. After this patch, an IMA policy rule along the lines of: measure func=CREDS_CHECK subj_type=unconfined_t will trigger if a process is executed and runs as unconfined_t, ignoring the context of the parent process. This is in contrast to: measure func=BPRM_CHECK subj_type=unconfined_t which will trigger if the process that calls exec() is already executing in unconfined_t, ignoring the context that the child process executes into.

usb: common: Small class for USB role switches
USB role switch is a device that can be used to choose the data role for USB connector. With dual-role capable USB controllers, the controller itself will be the switch, but on some platforms the USB host and device controllers are separate IPs and there is a mux between them and the connector. On those platforms the mux driver will need to register the switch. With USB Type-C connectors, the host-to-device relationship is negotiated over the Configuration Channel (CC). That means the USB Type-C drivers need to be in control of the role switch. The class provides a simple API for the USB Type-C drivers for the control. For other types of USB connectors (mainly microAB) the class provides user space control via sysfs attribute file that can be used to request role swapping from the switch.

usb: core: introduce per-port over-current counters
For some userspace applications information on the number of over-current conditions at specific USB hub ports is relevant. In our case we have a series of USB hardware (using the cp210x driver) which communicates using a proprietary protocol. These devices sometimes trigger an over-current situation on some hubs. In case of such an over-current situation the USB devices offer an interface for reducing the max used power. As these conditions are quite rare and imply performance reductions of the device we don't want to reduce the max power always. Therefore give user-space applications the possibility to react adequately by introducing an over_current_counter in the usb port struct which is exported via sysfs.

scsi: ufs: Add support for Auto-Hibernate Idle Timer
UFS host controllers may support an autonomous power management feature called the Auto-Hibernate Idle Timer. The timer is set to the number of microseconds of idle time before the UFS host controller will autonomously put the link into Hibernate state. That will save power at the expense of increased latency. Any access to the host controller interface registers will automatically put the link out of Hibernate state. So once configured, the feature is transparent to the driver. Expose the Auto-Hibernate Idle Timer value via SysFS to allow users to choose between power efficiency or lower latency. Set a default value of 150 ms. Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Stanislav Nijnikov <stanislav.nijnikov@wdc.com> Signed-off-by: Martin K.

ACPI: Add Time and Alarm Device (TAD) driver
Introduce a driver for the ACPI Time and Alarm Device (TAD) based on Section 9.18 of ACPI 6.2. This driver only supports the system wakeup capabilities of the TAD which are mandatory. Support for the RTC capabilities of the TAD will be added to it in the future. This driver is entirely sysfs-based. It provides attributes (under the TAD platform device) to allow user space to manage the AC and DC wakeup timers of the TAD: set and read their values, set and check their expire timer wake policies, check and clear their status and check the capabilities of the TAD reported by AML. The DC timer attributes are only present if the TAD supports a separate DC alarm timer. The wakeup events handling and power management of the TAD is expected to be taken care of by the ACPI PM domain attached to its platform device. Signed-off-by: Rafael J.

For example, external mode is selected by a user when an external debug device is attached to the FSI pins. To do this, we need to set specific states for the trans, mux and enable GPIOs, and prevent access to clk & data from the FSI core code (by returning EBUSY).

thunderbolt: Add support for preboot ACL
Preboot ACL is a mechanism that allows connecting Thunderbolt devices boot time in more secure way than the legacy Thunderbolt boot support. As with the legacy boot option, this also needs to be enabled from the BIOS before booting is allowed. Difference to the legacy mode is that the userspace software explicitly adds device UUIDs by sending a special message to the ICM firmware. Only the devices listed in the boot ACL are connected automatically during the boot. This works in both "user" and "secure" security levels. We implement this in Linux by exposing a new sysfs attribute (boot_acl) below each Thunderbolt domain. The userspace software can then update the full list as needed.

This information is interesting for user-space as if the device isn't in SW ACL, it may create a friction in the user experience where the device is automatically authorized if it's connected on boot but requires an explicit user action if connected after OS is up.

rtc: nvmem: allow registering the nvmem device before the rtc
Switch the parent of the nvmem device to the parent of the rtc device so it can be registered before the RTC. This is a small change in the ABI as the nvmem moves out of the /sys/class/rtc/rtcX folder to be under the parent device folder (that is where the previous nvram files where registered). However, it is still available under its correct location, /sys/bus/nvmem/devices which is the one that should be used by userspace applications. The other benefit is that the nvmem device can stay registered even if the rtc registration fails. Or it is possible to not register the rtc if the nvmem registration failed. Finally, it makes a lot of sense for devices that actually have different i2c or spi addresses for the RTC and the EEPROM. That is basically how it would end up when using MFD or even completely separate devices. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com> |

genirq: Add wakeup sysfs node to show IRQ wakeup state
Surprisingly there is no simple way to see if the IRQ line in question is wakeup source or not. Note that wakeup might be an OOB (out-of-band) source like GPIO line which makes things slightly more complicated. Add a sysfs node to cover this case.

powerpc updates for 4.16
Highlights:
- Enable support for memory protection keys aka "pkeys" on Power7/8/9 when
using the hash table MMU.
- Extend our interrupt soft masking to support masking PMU interrupts as well
as "normal" interrupts, and then use that to implement local_t for a ~4x
speedup vs the current atomics-based implementation.
- A new driver "ocxl" for "Open Coherent Accelerator Processor Interface
(OpenCAPI)" devices.
- Support for new device tree properties on PowerVM to describe hotpluggable
memory and devices.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 64-bit VDSO.
- Freescale updates from Scott:
"Contains fixes for CPM GPIO and an FSL PCI erratum workaround, plus a
minor cleanup patch."
As well as quite a lot of other changes all over the place, and small fixes and
cleanups as always.

Staging/IIO patches for 4.16-rc1
Here is the big Staging and IIO driver patches for 4.16-rc1. There is the normal amount of new IIO drivers added, like all releases. The networking IPX and the ncpfs filesystem are moved into the staging tree, as they are on their way out of the kernel due to lack of use anymore. The visorbus subsystem finall has started moving out of the staging tree to the "real" part of the kernel, and the most and fsl-mc codebases are almost ready to move out, that will probably happen for 4.17-rc1 if all goes well. Other than that, there is a bunch of license header cleanups in the tree, along with the normal amount of coding style churn that we all know and love for this codebase. I also got frustrated at the Meltdown/Spectre mess and took it out on the dgnc tty driver, deleting huge chunks of it that were never even being used. Full details of everything is in the shortlog.

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull integrity updates from James Morris: "This contains a mixture of bug fixes, code cleanup, and new functionality. Of note is the integrity cache locking fix, file change detection, and support for a new EVM portable and immutable signature type. The re-introduction of the integrity cache lock (iint) fixes the problem of attempting to take the i_rwsem shared a second time, when it was previously taken exclusively. Defining atomic flags resolves the original iint/i_rwsem circular locking - accessing the file data vs. modifying the file metadata. Although it fixes the O_DIRECT problem as well, a subsequent patch is needed to remove the explicit O_DIRECT prevention. For performance reasons, detecting when a file has changed and needs to be re-measured, re-appraised, and/or re-audited, was limited to after the last writer has closed, and only if the file data has changed. Detecting file change is based on i_version. For filesystems that do not support i_version, remote filesystems, or userspace filesystems, the file was measured, appraised and/or audited once and never re-evaluated. Now local filesystems, which do not support i_version or are not mounted with the i_version option, assume the file has changed and are required to re-evaluate the file. This change does not address detecting file change on remote or userspace filesystems. Unlike file data signatures, which can be included and distributed in software packages (eg. rpm, deb), the existing EVM signature, which protects the file metadata, could not be included in software packages, as it includes file system specific information (eg. i_ino, possibly the UUID). This pull request defines a new EVM portable and immutable file metadata signature format, which can be included in software packages" * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: ima/policy: fix parsing of fsuuid ima: Use i_version only when filesystem supports it integrity: remove unneeded initializations in integrity_iint_cache entries ima: log message to module appraisal error ima: pass filename to ima_rdwr_violation_check() ima: Fix line continuation format ima: support new "hash" and "dont_hash" policy actions ima: re-introduce own integrity cache lock EVM: Add support for portable signature format EVM: Allow userland to permit modification of EVM-protected metadata ima: relax requiring a file signature for new files with zero length |

f2fs-for-4.16-rc1
In this round, we've followed up to support some generic features such as
cgroup, block reservation, linking fscrypt_ops, delivering write_hints,
and some ioctls. And, we could fix some corner cases in terms of power-cut
recovery and subtle deadlocks.
Enhancement:
- bitmap operations to handle NAT blocks
- readahead to improve readdir speed
- switch to use fscrypt_*
- apply write hints for direct IO
- add reserve_root=%u,resuid=%u,resgid=%u to reserve blocks for root/uid/gid
- modify b_avail and b_free to consider root reserved blocks
- support cgroup writeback
- support FIEMAP_FLAG_XATTR for fibmap
- add F2FS_IOC_PRECACHE_EXTENTS to pre-cache extents
- add F2FS_IOC_{GET/SET}_PIN_FILE to pin LBAs for data blocks
- support inode creation time
Bug fix:
- sysfile-based quota operations
- memory footprint accounting
- allow to write data on partial preallocation case
- fix deadlock case on fallocate
- fix to handle fill_super errors
- fix missing inode updates of fsync'ed file
- recover renamed file which was fsycn'ed before
- drop inmemory pages in corner error case
- keep last_disk_size correctly
- recover missing i_inline flags during roll-forward
Various clean-up patches were added as well.

Merge branch 'x86-pti-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 pti updates from Thomas Gleixner:
"This contains:
- a PTI bugfix to avoid setting reserved CR3 bits when PCID is
disabled. This seems to cause issues on a virtual machine at least
and is incorrect according to the AMD manual.
- a PTI bugfix which disables the perf BTS facility if PTI is
enabled. The BTS AUX buffer is not globally visible and causes the
CPU to fault when the mapping disappears on switching CR3 to user
space. A full fix which restores BTS on PTI is non trivial and will
be worked on.
- PTI bugfixes for EFI and trusted boot which make sure that the user
space visible page table entries have the NX bit cleared
- removal of dead code in the PTI pagetable setup functions
- add PTI documentation
- add a selftest for vsyscall to verify that the kernel actually
implements what it advertises.
- a sysfs interface to expose vulnerability and mitigation
information so there is a coherent way for users to retrieve the
status.
- the initial spectre_v2 mitigations, aka retpoline:
+ The necessary ASM thunk and compiler support
+ The ASM variants of retpoline and the conversion of affected ASM
code
+ Make LFENCE serializing on AMD so it can be used as speculation
trap
+ The RSB fill after vmexit
- initial objtool support for retpoline
As I said in the status mail this is the most of the set of patches
which should go into 4.15 except two straight forward patches still on
hold:
- the retpoline add on of LFENCE which waits for ACKs
- the RSB fill after context switch
Both should be ready to go early next week and with that we'll have
covered the major holes of spectre_v2 and go back to normality"

siox: new driver framework for eckelmann SIOX
SIOX is a bus system invented at Eckelmann AG to control their building
management and refrigeration systems. Traditionally the bus was
implemented on custom microcontrollers, today Linux based machines are
in use, too.
The topology on a SIOX bus looks as follows:
,------->--DCLK-->---------------+----------------------.
^ v v
,--------. ,----------------------. ,------
| | | ,--------------. | |
| |--->--DOUT-->---|->-|shift register|->-|--->---|
| | | `--------------' | |
| master | | device | | device
| | | ,--------------. | |
| |---<--DIN---<---|-<-|shift register|-<-|---<---|
| | | `--------------' | |
`--------' `----------------------' `------
v ^ ^
`----------DLD-------------------+----------------------'
There are two control lines (DCLK and DLD) driven from the bus master to
all devices in parallel and two daisy chained data lines, one for input
and one for output. DCLK is the clock to shift both chains by a single
bit. On an edge of DLD the devices latch both their input and output
shift registers.
This patch adds a framework for this bus type.

ima: support new "hash" and "dont_hash" policy actions
The builtin ima_appraise_tcb policy, which is specified on the boot command line, can be replaced with a custom policy, normally early in the boot process. Custom policies can be more restrictive in some ways, like requiring file signatures, but can be less restrictive in other ways, like not appraising mutable files. With a less restrictive policy in place, files in the builtin policy might not be hashed and labeled with a security.ima hash. On reboot, files which should be labeled in the ima_appraise_tcb are not labeled, possibly preventing the system from booting properly. To resolve this problem, this patch extends the existing IMA policy actions "measure", "dont_measure", "appraise", "dont_appraise", and "audit" with "hash" and "dont_hash". The new "hash" action will write the file hash as security.ima, but without requiring the file to be appraised as well. For example, the builtin ima_appraise_tcb policy includes the rule, "appraise fowner=0". Adding the "hash fowner=0" rule to a custom policy, will cause the needed file hashes to be calculated and written as security.ima xattrs.

EVM: Allow userland to permit modification of EVM-protected metadata
When EVM is enabled it forbids modification of metadata protected by EVM unless there is already a valid EVM signature. If any modification is made, the kernel will then generate a new EVM HMAC. However, this does not map well on use cases which use only asymmetric EVM signatures, as in this scenario the kernel is unable to generate new signatures. This patch extends the /sys/kernel/security/evm interface to allow userland to request that modification of these xattrs be permitted. This is only permitted if no keys have already been loaded. In this configuration, modifying the metadata will invalidate the EVM appraisal on the file in question. This allows packaging systems to write out new files, set the relevant extended attributes and then move them into place. There's also some refactoring of the use of evm_initialized in order to avoid heading down codepaths that assume there's a key available.

usb: xhci: Add DbC support in xHCI driver
xHCI compatible USB host controllers(i.e. super-speed USB3 controllers) can be implemented with the Debug Capability(DbC). It presents a debug device which is fully compliant with the USB framework and provides the equivalent of a very high performance full-duplex serial link. The debug capability operation model and registers interface are defined in 7.6.8 of the xHCI specification, revision 1.1. The DbC debug device shares a root port with the xHCI host. By default, the debug capability is disabled and the root port is assigned to xHCI. When the DbC is enabled, the root port will be assigned to the DbC debug device, and the xHCI sees nothing on this port. This implementation uses a sysfs node named <dbc> under the xHCI device to manage the enabling and disabling of the debug capability. When the debug capability is enabled, it will present a debug device through the debug port. This debug device is fully compliant with the USB3 framework, and it can be enumerated by a debug host on the other end of the USB link. As soon as the debug device is configured, a TTY serial device named /dev/ttyDBC0 will be created.

livepatch: force transition to finish
If a task sleeps in a set of patched functions uninterruptedly, it could block the whole transition indefinitely. Thus it may be useful to clear its TIF_PATCH_PENDING to allow the process to finish. Admin can do that now by writing to force sysfs attribute in livepatch sysfs directory. TIF_PATCH_PENDING is then cleared for all tasks and the transition can finish successfully. Important note! Administrator should not use this feature without a clearance from a patch distributor. It must be checked that by doing so the consistency model guarantees are not violated. Removal (rmmod) of patch modules is permanently disabled when the feature is used. It cannot be guaranteed there is no task sleeping in such module.

livepatch: send a fake signal to all blocking tasks
Live patching consistency model is of LEAVE_PATCHED_SET and SWITCH_THREAD. This means that all tasks in the system have to be marked one by one as safe to call a new patched function. Safe means when a task is not (sleeping) in a set of patched functions. That is, no patched function is on the task's stack. Another clearly safe place is the boundary between kernel and userspace. The patching waits for all tasks to get outside of the patched set or to cross the boundary. The transition is completed afterwards. The problem is that a task can block the transition for quite a long time, if not forever. It could sleep in a set of patched functions, for example. Luckily we can force the task to leave the set by sending it a fake signal, that is a signal with no data in signal pending structures (no handler, no sign of proper signal delivered). Suspend/freezer use this to freeze the tasks as well. The task gets TIF_SIGPENDING set and is woken up (if it has been sleeping in the kernel before) or kicked by rescheduling IPI (if it was running on other CPU). This causes the task to go to kernel/userspace boundary where the signal would be handled and the task would be marked as safe in terms of live patching. There are tasks which are not affected by this technique though. The fake signal is not sent to kthreads. They should be handled differently. They can be woken up so they leave the patched set and their TIF_PATCH_PENDING can be cleared thanks to stack checking. For the sake of completeness, if the task is in TASK_RUNNING state but not currently running on some CPU it doesn't get the IPI, but it would eventually handle the signal anyway. Second, if the task runs in the kernel (in TASK_RUNNING state) it gets the IPI, but the signal is not handled on return from the interrupt. It would be handled on return to the userspace in the future when the fake signal is sent again. Stack checking deals with these cases in a better way. If the task was sleeping in a syscall it would be woken by our fake signal, it would check if TIF_SIGPENDING is set (by calling signal_pending() predicate) and return ERESTART* or EINTR. Syscalls with ERESTART* return values are restarted in case of the fake signal (see do_signal()). EINTR is propagated back to the userspace program. This could disturb the program, but... * each process dealing with signals should react accordingly to EINTR return values. * syscalls returning EINTR happen to be quite common situation in the system even if no fake signal is sent. * freezer sends the fake signal and does not deal with EINTR anyhow. Thus EINTR values are returned when the system is resumed. The very safe marking is done in architectures' "entry" on syscall and interrupt/exception exit paths, and in a stack checking functions of livepatch. TIF_PATCH_PENDING is cleared and the next recalc_sigpending() drops TIF_SIGPENDING. In connection with this, also call klp_update_patch_state() before do_signal(), so that recalc_sigpending() in dequeue_signal() can clear TIF_PATCH_PENDING immediately and thus prevent a double call of do_signal(). Note that the fake signal is not sent to stopped/traced tasks. Such task prevents the patching to finish till it continues again (is not traced anymore). Last, sending the fake signal is not automatic. It is done only when admin requests it by writing 1 to signal sysfs attribute in livepatch sysfs directory.

platform-drivers-x86 for v4.15-1
For this cycle we have quite an update for the Dell SMBIOS driver including WMI work to provide an interface for SMBIOS tokens via sysfs and WMI support for 2017+ Dell laptop models. SMM dispatcher code is split into a separate driver followed by a new WMI dispatcher. The latter provides a character device interface to user space. The pull request contains a merge of immutable branch from Wolfram Sang in order to apply a dependent fix to the Intel CherryTrail Battery Management driver. Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0 support is added for Intel Skylake. Peaq WMI hotkeys driver gets its own maintainer and white list of supported models. Silead DMI is expanded to support few additional platforms. Tablet mode via GMMS ACPI method is added to support some ThinkPad tablets. Two commits appear here which were previously merged during the v4.14-rcX cycle: - |

f2fs-for-4.15-rc1
In this round, we introduce sysfile-based quota support which is required
for Android by default. In addition, we allow that users are able to reserve
some blocks in runtime to mitigate performance drops in low free space.
Enhancement
- assign proper data segments according to write_hints given by user
- issue cache_flush on dirty devices only among multiple devices
- exploit cp_error flag and add more faults to enhance fault injection test
- conduct more readaheads during f2fs_readdir
- add a range for discard commands
Bug fix
- fix zero stat->st_blocks when inline_data is set
- drop crypto key and free stale memory pointer while evict_inode is failing
- fix some corner cases in free space and segment management
- fix wrong last_disk_size
This series includes lots of clean-ups and code enhancement in terms of xattr
operations, discard/flush command control. In addition, it adds versatile
debugfs entries to monitor f2fs status.

This is the bulk of GPIO changes for the v4.15 kernel cycle:
CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal
of dead code etc.
- Explicit comments on fall-through switch() statements.

Staging/IIO patches for 4.15-rc1
Here is the "big" staging and IIO driver update for 4.15-rc1. Lots and lots of little changes, almost all minor code cleanups as the Outreachy application process happened during this development cycle. Also happened was a lot of IIO driver activity, and the typec USB code moving out of staging to drivers/usb (same commits are in the USB tree on a persistent branch to not cause merge issues.) Overall, it's a wash, I think we added a few hundred more lines than removed, but really only a few thousand were modified at all. All of these have been in linux-next for a while. There might be a merge issue with Al's vfs tree in the pi433 driver (take his changes, they are always better), and the media tree with some of the odd atomisp cleanups (take the media tree's version).

Power management updates for v4.15-rc1
- Relocate the OPP (Operating Performance Points) framework to its
own directory under drivers/ and add support for power domain
performance states to it (Viresh Kumar).
- Modify the PM core, the PCI bus type and the ACPI PM domain to
support power management driver flags allowing device drivers to
specify their capabilities and preferences regarding the handling
of devices with enabled runtime PM during system suspend/resume
and clean up that code somewhat (Rafael Wysocki, Ulf Hansson).
- Add frequency-invariant accounting support to the task scheduler
on ARM and ARM64 (Dietmar Eggemann).
- Fix PM QoS device resume latency framework to prevent "no
restriction" requests from overriding requests with specific
requirements and drop the confusing PM_QOS_FLAG_REMOTE_WAKEUP
device PM QoS flag (Rafael Wysocki).
- Drop legacy class suspend/resume operations from the PM core
and drop legacy bus type suspend and resume callbacks from
ARM/locomo (Rafael Wysocki).
- Add min/max frequency support to devfreq and clean it up
somewhat (Chanwoo Choi).
- Rework wakeup support in the generic power domains (genpd)
framework and update some of its users accordingly (Geert
Uytterhoeven).
- Convert timers in the PM core to use timer_setup() (Kees Cook).
- Add support for exposing the SLP_S0 (Low Power S0 Idle)
residency counter based on the LPIT ACPI table on Intel
platforms (Srinivas Pandruvada).
- Add per-CPU PM QoS resume latency support to the ladder cpuidle
governor (Ramesh Thomas).
- Fix a deadlock between the wakeup notify handler and the
notifier removal in the ACPI core (Ville Syrjälä).
- Fix a cpufreq schedutil governor issue causing it to use
stale cached frequency values sometimes (Viresh Kumar).
- Fix an issue in the system suspend core support code causing
wakeup events detection to fail in some cases (Rajat Jain).
- Fix the generic power domains (genpd) framework to prevent
the PM core from using the direct-complete optimization with
it as that is guaranteed to fail (Ulf Hansson).
- Fix a minor issue in the cpuidle core and clean it up a bit
(Gaurav Jindal, Nicholas Piggin).

Pull power management updates from Rafael Wysocki:
"There are no real big ticket items here this time.
The most noticeable change is probably the relocation of the OPP
(Operating Performance Points) framework to its own directory under
drivers/ as it has grown big enough for that. Also Viresh is now going
to maintain it and send pull requests for it to me, so you will see
this change in the git history going forward (but still not right
now).
Another noticeable set of changes is the modifications of the PM core,
the PCI subsystem and the ACPI PM domain to allow of more integration
between system-wide suspend/resume and runtime PM. For now it's just a
way to avoid resuming devices from runtime suspend unnecessarily
during system suspend (if the driver sets a flag to indicate its
readiness for that) and in the works is an analogous mechanism to
allow devices to stay suspended after system resume.
In addition to that, we have some changes related to supporting
frequency-invariant CPU utilization metrics in the scheduler and in
the schedutil cpufreq governor on ARM and changes to add support for
device performance states to the generic power domains (genpd)
framework.
The rest is mostly fixes and cleanups of various sorts.

EVM: Allow userspace to signal an RSA key has been loaded
EVM will only perform validation once a key has been loaded. This key may either be a symmetric trusted key (for HMAC validation and creation) or the public half of an asymmetric key (for digital signature validation). The /sys/kernel/security/evm interface allows userland to signal that a symmetric key has been loaded, but does not allow userland to signal that an asymmetric public key has been loaded. This patch extends the interface to permit userspace to pass a bitmask of loaded key types. It also allows userspace to block loading of a symmetric key in order to avoid a compromised system from being able to load an additional key type later.

PM / QoS: Fix device resume latency framework
The special value of 0 for device resume latency PM QoS means
"no restriction", but there are two problems with that.
First, device resume latency PM QoS requests with 0 as the
value are always put in front of requests with positive
values in the priority lists used internally by the PM QoS
framework, causing 0 to be chosen as an effective constraint
value. However, that 0 is then interpreted as "no restriction"
effectively overriding the other requests with specific
restrictions which is incorrect.
Second, the users of device resume latency PM QoS have no
way to specify that *any* resume latency at all should be
avoided, which is an artificial limitation in general.
To address these issues, modify device resume latency PM QoS to
use S32_MAX as the "no constraint" value and 0 as the "no
latency at all" one and rework its users (the cpuidle menu
governor, the genpd QoS governor and the runtime PM framework)
to follow these changes.
Also add a special "n/a" value to the corresponding user space I/F
to allow user space to indicate that it cannot accept any resume
latencies at all for the given device.

platform/x86: dell-smbios-wmi: introduce userspace interface
It's important for the driver to provide a R/W ioctl to ensure that two competing userspace processes don't race to provide or read each others data. This userspace character device will be used to perform SMBIOS calls from any applications. It provides an ioctl that will allow passing the WMI calling interface buffer between userspace and kernel space. This character device is intended to deprecate the dcdbas kernel module and the interface that it provides to userspace. To perform an SMBIOS IOCTL call using the character device userspace will perform a read() on the the character device. The WMI bus will provide a u64 variable containing the necessary size of the IOCTL buffer. The API for interacting with this interface is defined in documentation as well as the WMI uapi header provides the format of the structures. Not all userspace requests will be accepted. The dell-smbios filtering functionality will be used to prevent access to certain tokens and calls. All whitelisted commands and tokens are now shared out to userspace so applications don't need to define them in their own headers.

platform/x86: dell-smbios: Add a sysfs interface for SMBIOS tokens
Currently userspace tools can access system tokens via the dcdbas kernel module and a SMI call that will cause the platform to execute SMM code. With a goal in mind of deprecating the dcdbas kernel module a different method for accessing these tokens from userspace needs to be created. This is intentionally marked to only be readable as a process with CAP_SYS_ADMIN as it can contain sensitive information about the platform's configuration. While adding this interface I found that some tokens are duplicated. These need to be ignored from sysfs to avoid duplicate files. MAINTAINERS was missing for this driver. Add myself and Pali to maintainers list for it.

Update MIPS email addresses
MIPS will soon not be a part of Imagination Technologies, and as such many @imgtec.com email addresses will no longer be valid. This patch updates the addresses for those who: - Have 10 or more patches in mainline authored using an @imgtec.com email address, or any patches dated within the past year. - Are still with Imagination but leaving as part of the MIPS business unit, as determined from an internal email address list. - Haven't already updated their email address (ie. JamesH) or expressed a desire to be excluded (ie. Maciej). - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt & myself. New addresses are of the form firstname.lastname@mips.com, and all verified against an internal email address list.

PM / QoS: Fix device resume latency PM QoS
The special value of 0 for device resume latency PM QoS means
"no restriction", but there are two problems with that.
First, device resume latency PM QoS requests with 0 as the
value are always put in front of requests with positive
values in the priority lists used internally by the PM QoS
framework, causing 0 to be chosen as an effective constraint
value. However, that 0 is then interpreted as "no restriction"
effectively overriding the other requests with specific
restrictions which is incorrect.
Second, the users of device resume latency PM QoS have no
way to specify that *any* resume latency at all should be
avoided, which is an artificial limitation in general.
To address these issues, modify device resume latency PM QoS to
use S32_MAX as the "no constraint" value and 0 as the "no
latency at all" one and rework its users (the cpuidle menu
governor, the genpd QoS governor and the runtime PM framework)
to follow these changes.
Also add a special "n/a" value to the corresponding user space I/F
to allow user space to indicate that it cannot accept any resume
latencies at all for the given device.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
There were quite a few overlapping sets of changes here. Daniel's bug fix for off-by-ones in the new BPF branch instructions, along with the added allowances for "data_end > ptr + x" forms collided with the metadata additions. Along with those three changes came veritifer test cases, which in their final form I tried to group together properly. If I had just trimmed GIT's conflict tags as-is, this would have split up the meta tests unnecessarily. In the socketmap code, a set of preemption disabling changes overlapped with the rename of bpf_compute_data_end() to bpf_compute_data_pointers(). Changes were made to the mv88e6060.c driver set addr method which got removed in net-next. The hyperv transport socket layer had a locking change in 'net' which overlapped with a change of socket state macro usage in 'net-next'. Signed-off-by: David S. Miller <davem@davemloft.net> |

iio: dac: Add Texas Instruments 8/10/12-bit 2/4-channel DAC driver
The DACrrcS085 (rr = 08/10/12, c = 2/4) family of SPI DACs was inherited by TI when they acquired National Semiconductor in 2011. This driver was developed for and tested with the DAC082S085 built into the Revolution Pi by KUNBUS, but should work with any of the other chips as they share the same programming interface. There is also a family of I2C DACs with just a single channel called DACrr1C08x (rr = 08/10/12, x = 1/5). Their programming interface is very similar and it should be possible to extend the driver for these chips with moderate effort. Alternatively they could be integrated into ad5446.c. (The AD5301/AD5311/AD5321 use different power-down modes but otherwise appear to be comparable.) Furthermore there is a family of 8-channel DACs called DACrr8S085 (rr = 08/10/12) as well as two 16-bit DACs called DAC161Sxxx (xxx = 055/997). These are more complicated devices with support for daisy-chaining and the ability to power down each channel separately. They could either be handled by a separate driver or integrated into the present driver with a larger effort.

mm, swap: use page-cluster as max window of VMA based swap readahead
When the VMA based swap readahead was introduced, a new knob
/sys/kernel/mm/swap/vma_ra_max_order
was added as the max window of VMA swap readahead. This is to make it
possible to use different max window for VMA based readahead and
original physical readahead. But Minchan Kim pointed out that this will
cause a regression because setting page-cluster sysctl to zero cannot
disable swap readahead with the change.
To fix the regression, the page-cluster sysctl is used as the max window
of both the VMA based swap readahead and original physical swap
readahead. If more fine grained control is needed in the future, more
knobs can be added as the subordinate knobs of the page-cluster sysctl.
The vma_ra_max_order knob is deleted. Because the knob was introduced
in v4.14-rc1, and this patch is targeting being merged before v4.14
releasing, there should be no existing users of this newly added ABI.

thunderbolt: Add support for XDomain discovery protocol
When two hosts are connected over a Thunderbolt cable, there is a protocol they can use to communicate capabilities supported by the host. The discovery protocol uses automatically configured control channel (ring 0) and is build on top of request/response transactions using special XDomain primitives provided by the Thunderbolt base protocol. The capabilities consists of a root directory block of basic properties used for identification of the host, and then there can be zero or more directories each describing a Thunderbolt service and its capabilities. Once both sides have discovered what is supported the two hosts can setup high-speed DMA paths and transfer data to the other side using whatever protocol was agreed based on the properties. The software protocol used to communicate which DMA paths to enable is service specific. This patch adds support for the XDomain discovery protocol to the Thunderbolt bus. We model each remote host connection as a Linux XDomain device. For each Thunderbolt service found supported on the XDomain device, we create Linux Thunderbolt service device which Thunderbolt service drivers can then bind to based on the protocol identification information retrieved from the property directory describing the service. This code is based on the work done by Amir Levy and Michael Jamet.

platform/x86: Add driver to force WMI Thunderbolt controller power status
Current implementations of Intel Thunderbolt controllers will go into a low power mode when not in use. Many machines containing these controllers also have a GPIO wired up that can force the controller awake. This is offered via a ACPI-WMI interface intended to be manipulated by a userspace utility. This mechanism is provided by Intel to OEMs to include in BIOS. It uses an industry wide GUID that is populated in a separate _WDG entry with no binary MOF. This interface allows software such as fwupd to wake up thunderbolt controllers to query the firmware version or flash new firmware.

powerpc updates for 4.14
Nothing really major this release, despite quite a lot of activity. Just lots of
things all over the place.
Some things of note include:
- Access via perf to a new type of PMU (IMC) on Power9, which can count both
core events as well as nest unit events (Memory controller etc).
- Optimisations to the radix MMU TLB flushing, mostly to avoid unnecessary Page
Walk Cache (PWC) flushes when the structure of the tree is not changing.
- Reworks/cleanups of do_page_fault() to modernise it and bring it closer to
other architectures where possible.
- Rework of our page table walking so that THP updates only need to send IPIs
to CPUs where the affected mm has run, rather than all CPUs.
- The size of our vmalloc area is increased to 56T on 64-bit hash MMU systems.
This avoids problems with the percpu allocator on systems with very sparse
NUMA layouts.
- STRICT_KERNEL_RWX support on PPC32.
- A new sched domain topology for Power9, to capture the fact that pairs of
cores may share an L2 cache.
- Power9 support for VAS, which is a new mechanism for accessing coprocessors,
and initial support for using it with the NX compression accelerator.
- Major work on the instruction emulation support, adding support for many new
instructions, and reworking it so it can be used to implement the emulation
needed to fixup alignment faults.
- Support for guests under PowerVM to use the Power9 XIVE interrupt controller.
And probably that many things again that are almost as interesting, but I had to
keep the list short. Plus the usual fixes and cleanups as always.

mm: add /proc/pid/smaps_rollup
/proc/pid/smaps_rollup is a new proc file that improves the performance
of user programs that determine aggregate memory statistics (e.g., total
PSS) of a process.
Android regularly "samples" the memory usage of various processes in
order to balance its memory pool sizes. This sampling process involves
opening /proc/pid/smaps and summing certain fields. For very large
processes, sampling memory use this way can take several hundred
milliseconds, due mostly to the overhead of the seq_printf calls in
task_mmu.c.
smaps_rollup improves the situation. It contains most of the fields of
/proc/pid/smaps, but instead of a set of fields for each VMA,
smaps_rollup instead contains one synthetic smaps-format entry
representing the whole process. In the single smaps_rollup synthetic
entry, each field is the summation of the corresponding field in all of
the real-smaps VMAs. Using a common format for smaps_rollup and smaps
allows userspace parsers to repurpose parsers meant for use with
non-rollup smaps for smaps_rollup, and it allows userspace to switch
between smaps_rollup and smaps at runtime (say, based on the
availability of smaps_rollup in a given kernel) with minimal fuss.
By using smaps_rollup instead of smaps, a caller can avoid the
significant overhead of formatting, reading, and parsing each of a large
process's potentially very numerous memory mappings. For sampling
system_server's PSS in Android, we measured a 12x speedup, representing
a savings of several hundred milliseconds.
One alternative to a new per-process proc file would have been including
PSS information in /proc/pid/status. We considered this option but
thought that PSS would be too expensive (by a few orders of magnitude)
to collect relative to what's already emitted as part of
/proc/pid/status, and slowing every user of /proc/pid/status for the
sake of readers that happen to want PSS feels wrong.
The code itself works by reusing the existing VMA-walking framework we
use for regular smaps generation and keeping the mem_size_stats
structure around between VMA walks instead of using a fresh one for each
VMA. In this way, summation happens automatically. We let seq_file
walk over the VMAs just as it does for regular smaps and just emit
nothing to the seq_file until we hit the last VMA.
Benchmarks:
using smaps:
iterations:1000 pid:1163 pss:220023808
0m29.46s real 0m08.28s user 0m20.98s system
using smaps_rollup:
iterations:1000 pid:1163 pss:220702720
0m04.39s real 0m00.03s user 0m04.31s system
We're using the PSS samples we collect asynchronously for
system-management tasks like fine-tuning oom_adj_score, memory use
tracking for debugging, application-level memory-use attribution, and
deciding whether we want to kill large processes during system idle
maintenance windows. Android has been using PSS for these purposes for
a long time; as the average process VMA count has increased and and
devices become more efficiency-conscious, PSS-collection inefficiency
has started to matter more. IMHO, it'd be a lot safer to optimize the
existing PSS-collection model, which has been fine-tuned over the years,
instead of changing the memory tracking approach entirely to work around
smaps-generation inefficiency.
Tim said:
: There are two main reasons why Android gathers PSS information:
:
: 1. Android devices can show the user the amount of memory used per
: application via the settings app. This is a less important use case.
:
: 2. We log PSS to help identify leaks in applications. We have found
: an enormous number of bugs (in the Android platform, in Google's own
: apps, and in third-party applications) using this data.
:
: To do this, system_server (the main process in Android userspace) will
: sample the PSS of a process three seconds after it changes state (for
: example, app is launched and becomes the foreground application) and about
: every ten minutes after that. The net result is that PSS collection is
: regularly running on at least one process in the system (usually a few
: times a minute while the screen is on, less when screen is off due to
: suspend). PSS of a process is an incredibly useful stat to track, and we
: aren't going to get rid of it. We've looked at some very hacky approaches
: using RSS ("take the RSS of the target process, subtract the RSS of the
: zygote process that is the parent of all Android apps") to reduce the
: accounting time, but it regularly overestimated the memory used by 20+
: percent. Accordingly, I don't think that there's a good alternative to
: using PSS.
:
: We started looking into PSS collection performance after we noticed random
: frequency spikes while a phone's screen was off; occasionally, one of the
: CPU clusters would ramp to a high frequency because there was 200-300ms of
: constant CPU work from a single thread in the main Android userspace
: process. The work causing the spike (which is reasonable governor
: behavior given the amount of CPU time needed) was always PSS collection.
: As a result, Android is burning more power than we should be on PSS

: The other issue (and why I'm less sure about improving smaps as a
: long-term solution) is that the number of VMAs per process has increased
: significantly from release to release. After trying to figure out why we
: were seeing these 200-300ms PSS collection times on Android O but had not
: noticed it in previous versions, we found that the number of VMAs in the
: main system process increased by 50% from Android N to Android O (from
: ~1800 to ~2700) and varying increases in every userspace process. Android
: M to N also had an increase in the number of VMAs, although not as much.
: I'm not sure why this is increasing so much over time, but thinking about
: ASLR and ways to make ASLR better, I expect that this will continue to
: increase going forward. I would not be surprised if we hit 5000 VMAs on
: the main Android process (system_server) by 2020.
:
: If we assume that the number of VMAs is going to increase over time, then
: doing anything we can do to reduce the overhead of each VMA during PSS
: collection seems like the right way to go, and that means outputting an
: aggregate statistic (to avoid whatever overhead there is per line in
: writing smaps and in reading each line from userspace).

Power management updates for v4.14-rc1
- Drop the P-state selection algorithm based on a PID controller
from intel_pstate and make it use the same P-state selection
method (based on the CPU load) for all types of systems in the
active mode (Rafael Wysocki, Srinivas Pandruvada).
- Rework the cpufreq core and governors to make it possible to
take cross-CPU utilization updates into account and modify the
schedutil governor to actually do so (Viresh Kumar).
- Clean up the handling of transition latency information in the
cpufreq core and untangle it from the information on which drivers
cannot do dynamic frequency switching (Viresh Kumar).
- Add support for new SoCs (MT2701/MT7623 and MT7622) to the
mediatek cpufreq driver and update its DT bindings (Sean Wang).
- Modify the cpufreq dt-platdev driver to autimatically create
cpufreq devices for the new (v2) Operating Performance Points
(OPP) DT bindings and update its whitelist of supported systems
(Viresh Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen,
Finley Xiao).
- Add support for Ux500 to the cpufreq-dt driver and drop the
obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
- Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
Nguyen).
- Fix and clean up assorted issues in the cpufreq drivers and core
(Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
- Update the IO-wait boost handling in the schedutil governor to
make it less aggressive (Joel Fernandes).
- Rework system suspend diagnostics to make it print fewer messages
to the kernel log by default, add a sysfs knob to allow more
suspend-related messages to be printed and add Low Power S0 Idle
constraints checks to the ACPI suspend-to-idle code (Rafael
Wysocki, Srinivas Pandruvada).
- Prefer suspend-to-idle over S3 on ACPI-based systems with the
ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
interface present in the ACPI tables (Rafael Wysocki).
- Update documentation related to system sleep and rename a number
of items in the code to make it cleare that they are related to
suspend-to-idle (Rafael Wysocki).
- Export a variable allowing device drivers to check the target
system sleep state from the core system suspend code (Florian
Fainelli).
- Clean up the cpuidle subsystem to handle the polling state on
x86 in a more straightforward way and to use %pOF instead of
full_name (Rafael Wysocki, Rob Herring).
- Update the devfreq framework to fix and clean up a few minor
issues (Chanwoo Choi, Rob Herring).
- Extend diagnostics in the generic power domains (genpd) framework
and clean it up slightly (Thara Gopinath, Rob Herring).
- Fix and clean up a couple of issues in the operating performance
points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).

Pull power management updates from Rafael Wysocki:
"This time (again) cpufreq gets the majority of changes which mostly
are driver updates (including a major consolidation of intel_pstate),
some schedutil governor modifications and core cleanups.
There also are some changes in the system suspend area, mostly related
to diagnostics and debug messages plus some renames of things related
to suspend-to-idle. One major change here is that suspend-to-idle is
now going to be preferred over S3 on systems where the ACPI tables
indicate to do so and provide requsite support (the Low Power Idle S0
_DSM in particular). The system sleep documentation and the tools
related to it are updated too.
The rest is a few cpuidle changes (nothing major), devfreq updates,
generic power domains (genpd) framework updates and a few assorted
modifications elsewhere.

usb: misc: lvstest: add entry to place port in compliance mode
Add support for the SuperSpeed Link Layer test case TD.7.34
which requires the operator to place the port into compliance
mode, and to subsequently bring it out via reset. Historically
according to the (now deprecated) USB 3.0 specification a
SuperSpeed host downstream port would automatically transition
to Compliance mode from the Polling state if LFPS polling times
out. However the language in USB 3.1 as well as xHCI 1.1 states
it may be required to explicitly enable this transition. For
such hosts this is done by sending a SET_FEATURE(PORT_LINK_STATE)
with the state set to Compliance to the root hub port.
Similar to the other supported commands, to do this via sysfs:
echo > /sys/bus/usb/devices/2-0\:1.0/enable_compliance
According to xHCI 1.1 section 4.19.1.2.4.1, this enables the
transition to compliance mode upon LFPS timeout. Note that this
can only be issued when the port is in disconnected state. And
in order to disable this behavior on subsequent transitions, a
warm reset should be issued. So add another entry to do that:
echo > /sys/bus/usb/devices/2-0\:1.0/warm_reset
In general these attributes can also be useful for other USB
SuperSpeed compliance tests such as electrical and eye diagram
testing which require CPn patterns to be transmitted.

First round of IIO new device support, features and cleanups for the 4.14 cycle.
4 completely new drivers in this set and plenty of other stuff.
One ABI change due to a silly mistake a long time back. Hopefully no
one will notice. It effects the numerical order of consumer device
channels which was the reverse of the obvious. It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)

- new driver for the Volatile Organic Compounds (VOC) sensor.
* dln2 adc
- new driver for the ADC on this flexible usb board.
* EP93xx
- new driver for this Cirrus logic SoC ADC.
* ltc2471

Merge tag 'iio-for-4.14a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First round of IIO new device support, features and cleanups for the 4.14 cycle.
4 completely new drivers in this set and plenty of other stuff.
One ABI change due to a silly mistake a long time back. Hopefully no
one will notice. It effects the numerical order of consumer device
channels which was the reverse of the obvious. It's going the slow
way to allow us some margin to spot if we have broken userspace or
not (seems unlikely)
New Device Support
* ccs811
- new driver for the Volatile Organic Compounds (VOC) sensor.

PM / sleep: Do not print debug messages by default
Debug messages from the system suspend/hibernation infrastructure can fill up the entire kernel log buffer in some cases and anyway they are only useful for debugging. They depend on CONFIG_PM_DEBUG, but that is set as a rule as some generally useful diagnostic facilities depend on it too. For this reason, avoid printing those messages by default, but make it possible to turn them on as needed with the help of a new sysfs attribute under /sys/power/. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

* addition of on-die ECC support to Micron driver
* addition of helpers to help drivers choose most appropriate ECC
settings
* deletion of dead-code (cached programming and ->errstat() hook)
* make sure drivers that do not support the SET/GET FEATURES command
return ENOTSUPP use a dummy ->set/get_features implementation
returning -ENOTSUPP (required for Micron on-die ECC)
* change the semantic of ecc->write_page() for drivers setting the
NAND_ECC_CUSTOM_PAGE_ACCESS flag
* support exiting 'GET STATUS' command in default ->cmdfunc()
implementations
* change the prototype of ->setup_data_interface()
A bunch of driver related changes:
* various cleanup, fixes and improvements of the MTK driver
* OMAP DT bindings fixes
* support for ->setup_data_interface() in the fsmc driver
* support for imx7 in the gpmi driver
* finalization of the denali driver rework (thanks to Masahiro for the

for-f2fs-4.13
In this round, we've added new features such as disk quota and statx, and
modified internal bio management flow to merge more IOs depending on block
types. We've also made internal threads freezeable for Android battery life.
In addition to them, there are some patches to avoid lock contention as well
as a couple of deadlock conditions.
= Enhancement
- support usrquota, grpquota, and statx
- manage DATA/NODE typed bios separately to serialize more IOs
- modify f2fs_lock_op/wio_mutex to avoid lock contention
- prevent lock contention in migratepage
= Bug fix
- miss to load written inode flag
- fix worst case victim selection in GC
- freezeable GC and discard threads for Android battery life
- sanitize f2fs metadata to deal with security hole
- clean up sysfs-related code and docs

f2fs: introduce reserved_blocks in sysfs
In this patch, we add a new sysfs interface, with it, we can control number of reserved blocks in system which could not be used by user, it enable f2fs to let user to configure for adjusting over-provision ratio dynamically instead of changing it by mkfs. So we can expect it will help to reserve more free space for relieving GC in both filesystem and flash device.

Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security layer updates from James Morris:
- a major update for AppArmor. From JJ:
* several bug fixes and cleanups
* the patch to add symlink support to securityfs that was floated
on the list earlier and the apparmorfs changes that make use of
securityfs symlinks
* it introduces the domain labeling base code that Ubuntu has been
carrying for several years, with several cleanups applied. And it
converts the current mediation over to using the domain labeling
base, which brings domain stacking support with it. This finally
will bring the base upstream code in line with Ubuntu and provide
a base to upstream the new feature work that Ubuntu carries.
* This does _not_ contain any of the newer apparmor mediation
features/controls (mount, signals, network, keys, ...) that
Ubuntu is currently carrying, all of which will be RFC'd on top
of this.
- Notable also is the Infiniband work in SELinux, and the new file:map
permission. From Paul:
"While we're down to 21 patches for v4.13 (it was 31 for v4.12),
the diffstat jumps up tremendously with over 2k of line changes.
Almost all of these changes are the SELinux/IB work done by
Daniel Jurgens; some other noteworthy changes include a NFS v4.2
labeling fix, a new file:map permission, and reporting of policy
capabilities on policy load"
There's also now genfscon labeling support for tracefs, which was
lost in v4.1 with the separation from debugfs.
- Smack incorporates a safer socket check in file_receive, and adds a
cap_capable call in privilege check.
- TPM as usual has a bunch of fixes and enhancements.
- Multiple calls to security_add_hooks() can now be made for the same
LSM, to allow LSMs to have hook declarations across multiple files.
- IMA now supports different "ima_appraise=" modes (eg. log, fix) from
the boot command line.
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (126 commits)

Char/Misc patches for 4.13-rc1
Here is the "big" char/misc driver patchset for 4.13-rc1. Lots of stuff in here, a large thunderbolt update, w1 driver header reorg, the new mux driver subsystem, google firmware driver updates, and a raft of other smaller things.

usb: gadget: add f_uac1 variant based on a new u_audio api
This patch adds a new function 'f_uac1' (f_uac1 with virtual "ALSA card") that uses recently created u_audio API. Comparing to legacy f_uac1 function implementation it doesn't require any real Audio codec to be present on the device. In f_uac1 audio streams are simply sinked to and sourced from a virtual ALSA sound card created using u_audio API. Legacy f_uac1 approach is to write audio samples directly to existing ALSA sound card f_uac1 approach is more generic/flexible one - create an ALSA sound card that represents USB Audio function and allows to be used by userspace application that may choose to do whatever it wants with the data received from the USB Host and choose to provide whatever it wants as audio data to the USB Host. f_uac1 also has capture support (gadget->host) thanks to easy implementation via u_audio. By default, capture interface has 48000kHz/2ch configuration, same as playback channel has. f_uac1 descriptors naming convention uses f_uac2 driver naming convention that makes it more common and meaningful. Comparing to f_uac1_legacy, the f_uac1 doesn't have volume/mute functionality. This is because the f_uac1 volume/mute feature unit was dummy implementation since that driver creation (2009) and never had any real volume control or mute functionality, so there is no any difference here. Since f_uac1 functionality, exposed interface to userspace (virtual ALSA card), input parameters are so different comparing to f_uac1_legacy, that there is no any reason to keep them in the same file/module, and separate function was created. g_audio can be built using one of existing UAC functions (f_uac1, f_uac1_legacy or f_uac2) Signed-off-by: Ruslan Bilovol <ruslan.bilovol@gmail.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |

thunderbolt: Add support for host and device NVM firmware upgrade
Starting from Intel Falcon Ridge the NVM firmware can be upgraded by using DMA configuration based mailbox commands. If we detect that the host or device (device support starts from Intel Alpine Ridge) has the DMA configuration based mailbox we expose NVM information to the userspace as two separate Linux NVMem devices: nvm_active and nvm_non_active. The former is read-only portion of the active NVM which firmware upgrade tools can be use to find out suitable NVM image if the device identification strings are not enough. The latter is write-only portion where the new NVM image is to be written by the userspace. It is up to the userspace to find out right NVM image (the kernel does very minimal validation). The ICM firmware itself authenticates the new NVM firmware and fails the operation if it is not what is expected. We also expose two new sysfs files per each switch: nvm_version and nvm_authenticate which can be used to read the active NVM version and start the upgrade process. We also introduce safe mode which is the mode a switch goes when it does not have properly authenticated firmware. In this mode the switch only accepts a couple of commands including flashing a new NVM firmware image and triggering power cycle. This code is based on the work done by Amir Levy and Michael Jamet.

thunderbolt: Add support for Internal Connection Manager (ICM)
Starting from Intel Falcon Ridge the internal connection manager running
on the Thunderbolt host controller has been supporting 4 security
levels. One reason for this is to prevent DMA attacks and only allow
connecting devices the user trusts.
The internal connection manager (ICM) is the preferred way of connecting
Thunderbolt devices over software only implementation typically used on
Macs. The driver communicates with ICM using special Thunderbolt ring 0
(control channel) messages. In order to handle these messages we add
support for the ICM messages to the control channel.
The security levels are as follows:
none - No security, all tunnels are created automatically
user - User needs to approve the device before tunnels are created
secure - User need to approve the device before tunnels are created.
The device is sent a challenge on future connects to be able
to verify it is actually the approved device.
dponly - Only Display Port and USB tunnels can be created and those
are created automatically.
The security levels are typically configurable from the system BIOS and
by default it is set to "user" on many systems.
In this patch each Thunderbolt device will have either one or two new
sysfs attributes: authorized and key. The latter appears for devices
that support secure connect.
In order to identify the device the user can read identication
information, including UUID and name of the device from sysfs and based
on that make a decision to authorize the device. The device is
authorized by simply writing 1 to the "authorized" sysfs attribute. This
is following the USB bus device authorization mechanism. The secure
connect requires an additional challenge step (writing 2 to the
"authorized" attribute) in future connects when the key has already been
stored to the NVM of the device.
Non-ICM systems (before Alpine Ridge) continue to use the existing
functionality and the security level is set to none. For systems with
Alpine Ridge, even on Apple hardware, we will use ICM.
This code is based on the work done by Amir Levy and Michael Jamet.

thunderbolt: Convert switch to a device
Thunderbolt domain consists of switches that are connected to each other, forming a bus. This will convert each switch into a real Linux device structure and adds them to the domain. The advantage here is that we get all the goodies from the driver core, like reference counting and sysfs hierarchy for free. Also expose device identification information to the userspace via new sysfs attributes. In order to support internal connection manager (ICM) we separate switch configuration into its own function (tb_switch_configure()) which is only called by the existing native connection manager implementation used on Macs.

net: phy: add XAUI and 10GBASE-KR PHY connection types
XAUI allows XGMII to reach an extended distance by using a XGXS layer at each end of the MAC to PHY link, operating over four Serdes lanes. 10GBASE-KR is a single lane Serdes backplane ethernet connection method with autonegotiation on the link. Some PHYs use this to connect to the ethernet interface at 10G speeds, switching to other connection types when utilising slower speeds. 10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber modules.

mux: minimal mux subsystem
Add a new minimalistic subsystem that handles multiplexer controllers. When multiplexers are used in various places in the kernel, and the same multiplexer controller can be used for several independent things, there should be one place to implement support for said multiplexer controller. A single multiplexer controller can also be used to control several parallel multiplexers, that are in turn used by different subsystems in the kernel, leading to a need to coordinate multiplexer accesses. The multiplexer subsystem handles this coordination. Thanks go out to Lars-Peter Clausen, Jonathan Cameron, Rob Herring, Wolfram Sang, Paul Gortmaker, Dan Carpenter, Colin Ian King, Greg Kroah-Hartman and last but certainly not least to Philipp Zabel for helpful comments, reviews, patches and general encouragement!

First set of new device support, features and cleanups for IIO in the 4.13 cycle
Two entirely new drivers in here plus the usual range of cleanups and features. New device support * ad5064 - add ltc2631, ltc2633 and ltc2635 support. * bma180 - trivial support for bma250e (new id) * hid-sensor-rotation - add relative orientation and geometric orientation support. * isl29028 - add isl29030 support (its effectively the same part from a driver point of view) * maxim_thermocouple - add max31856 id. * meson-saradc - add meson8b SoC adc support. * ti-adc084s021 - new driver and bindings. * ti-adc108s102 - new driver and bindings. Staging graduations * isl29028 Features * bma180 - ACPI enumeration for BMA250E which is used in various x86 tablets. * hi8453 - add raw access rather than only events. * hid-sensor-hub - Implement batch mode in which we can set a threshold on the amount of time between data coming from the fifos. This is the first device to do this rather than use a watershed on the number of samples. * hts221 - power management support * lsm6dsx - add system power management support. * rpr0521 - sampling frequency read / write * stm32-trigger - add support for TRG02 triggers. * tsl2583 - runtime power management support. Cleanups * core - inkern: fix a double unlock in iio_read_available_channel_raw when raw value doesn't appear to be raw (error path). - fixup accidental sizeof pointer in iio_device_add_mask_type. * docs - fix an accidental duplicated line in sysfs-bus-iio-meas-spec. * tools - use local include/uapi headers to ensure always up to date. - increase length of allowed trigger names. * ad9834 - symbolic to octal permissions. * ade7753 - symbolic to octal permissions. - fix indentation * ade7754 - symbolic to octal permissions. * ade7758 - symbolic to octal permissions. - |

kobject: support passing in variables for synthetic uevents
This patch makes it possible to pass additional arguments in addition
to uevent action name when writing /sys/.../uevent attribute. These
additional arguments are then inserted into generated synthetic uevent
as additional environment variables.
Before, we were not able to pass any additional uevent environment
variables for synthetic uevents. This made it hard to identify such uevents
properly in userspace to make proper distinction between genuine uevents
originating from kernel and synthetic uevents triggered from userspace.
Also, it was not possible to pass any additional information which would
make it possible to optimize and change the way the synthetic uevents are
processed back in userspace based on the originating environment of the
triggering action in userspace. With the extra additional variables, we are
able to pass through this extra information needed and also it makes it
possible to synchronize with such synthetic uevents as they can be clearly
identified back in userspace.
The format for writing the uevent attribute is following:
ACTION [UUID [KEY=VALUE ...]
There's no change in how "ACTION" is recognized - it stays the same
("add", "change", "remove"). The "ACTION" is the only argument required
to generate synthetic uevent, the rest of arguments, that this patch
adds support for, are optional.
The "UUID" is considered as transaction identifier so it's possible to
use the same UUID value for one or more synthetic uevents in which case
we logically group these uevents together for any userspace listeners.
The "UUID" is expected to be in "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
format where "x" is a hex digit. The value appears in uevent as
"SYNTH_UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" environment variable.
The "KEY=VALUE" pairs can contain alphanumeric characters only. It's
possible to define zero or more more pairs - each pair is then delimited
by a space character " ". Each pair appears in synthetic uevents as
"SYNTH_ARG_KEY=VALUE" environment variable. That means the KEY name gains
"SYNTH_ARG_" prefix to avoid possible collisions with existing variables.
To pass the "KEY=VALUE" pairs, it's also required to pass in the "UUID"
part for the synthetic uevent first.
If "UUID" is not passed in, the generated synthetic uevent gains
"SYNTH_UUID=0" environment variable automatically so it's possible to
identify this situation in userspace when reading generated uevent and so
we can still make a difference between genuine and synthetic uevents.

drivers/serial: Add driver for Aspeed virtual UART
This change adds a driver for the 16550-based Aspeed virtual UART device. We use a similar process to the of_serial driver for device probe, but expose some VUART-specific functions through sysfs too. The VUART is two UART 'front ends' connected by their FIFO (no actual serial line in between). One is on the BMC side (management controller) and one is on the host CPU side. This driver is for the BMC side. The sysfs files allow the BMC userspace, which owns the system configuration policy, to specify at what IO port and interrupt number the host side will appear to the host on the Host <-> BMC LPC bus. It could be different on a different system (though most of them use 3f8/4). OpenPOWER host firmware doesn't like it when the host-side of the VUART's FIFO is not drained. This driver only disables host TX discard mode when the port is in use. We set the VUART enabled bit when we bind to the device, and clear it on unbind. We don't want to do this on open/release, as the host may be using this bit to configure serial output modes, which is independent of whether the devices has been opened by BMC userspace.

platform/x86: ideapad-laptop: Add sysfs interface for touchpad state
Lenovo Yoga (many variants: Yoga, Yoga2 Pro, Yoga2 13, Yoga3 Pro, Yoga 3 14, etc) has multiple modles that are a hybrid laptop, working in laptop mode as well as tablet mode. Currently, there is no easy interface to determine the touchpad status, which in case of the Yoga family of machines, can also be useful to assume tablet mode status. Note: The ideapad-laptop driver does not provide a SW_TABLET_MODE either. For a detailed discussion on why we want either of the interfaces, please see: https://bugs.launchpad.net/onboard/+bug/1366421/comments/43 This patch adds a sysfs interface for read/write access under: /sys/bus/platform/devices/VPC2004\:00/touchpad_mode Signed-off-by: Ritesh Raj Sarraf <rrs@debian.org> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> |

Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to the Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff.

This extends the nature of the types of patches that can be applied by live patching infrastructure. The code stems from the design proposal made [1] back in November 2014. It's a hybrid of SUSE's kGraft and RH's kpatch, combining advantages of both: it uses kGraft's per-task consistency and syscall barrier switching combined with kpatch's stack trace switching. There are also a number of fallback options which make it quite flexible.

A reasonably busy cycle for documentation this time around. There is a new

consistent and robust and drop the force_remove sysfs attribute
that could be used to tell it to ignore errors on device
hot-removal which was dangerous in general and no real and
still relevant use cases for it could be found (Rafael Wysocki,
Michal Hocko).
- Make the core device enumeration code use _PXM to associate
platform devices created by it with specific NUMA nodes (Shanker
Donthineni).
- Extend the CPPC library by adding more sysfs entries for
performance capabilities to it and making it use the lowest
nonlinear performance parameter (Prashanth Prakash).
- Make the CPU online more consistent with CPU initialization in
the ACPI processor driver (Prashanth Prakash).
- Update the AC and battery drivers to help them avoid attaching to
devices that cannot be handled by them and update the axp288_charger
power supply driver to work correctly on ACPI systems without the
INT3496 device (Hans de Goede).
- Add an ACPI operation region driver for the Intel CHT Whiskey Cove
PMIC and update the xpower operation region driver to work without
IIO which isn't really necessary for it to work (Hans de Goede).
- Add a new entry for Dell Inspiron 7537 to the _REV quirk blacklist
(Kai Heng Feng).
- Make the code in the ACPI video driver easier to follow by adding
symbols and comments to it (Dmitry Frank).
- Update ACPI documentation and drop a function that has no users
from the tables-handling code (Cao jin, Baoquan He).

PCI: Add sysfs sriov_drivers_autoprobe to control VF driver binding
Sometimes it is not desirable to bind SR-IOV VFs to drivers. This can save host side resource usage by VF instances that will be assigned to VMs. Add a new PCI sysfs interface "sriov_drivers_autoprobe" to control that from the PF. To modify it, echo 0/n/N (disable probe) or 1/y/Y (enable probe) to: /sys/bus/pci/devices/<DOMAIN:BUS:DEVICE.FUNCTION>/sriov_drivers_autoprobe Note that this must be done before enabling VFs. The change will not take effect if VFs are already enabled. Simply, one can disable VFs by setting sriov_numvfs to 0, choose whether to probe or not, and then re-enable the VFs by restoring sriov_numvfs.

ACPI / scan: Drop support for force_remove
/sys/firmware/acpi/hotplug/force_remove was presumably added to support auto offlining in the past. This is, however, inherently dangerous for some hotplugable resources like memory. The memory offlining fails when the memory is still in use and cannot be dropped or migrated. If we ignore the failure we are basically allowing for subtle memory corruption or a crash. We have actually noticed the later while hitting BUG() during the memory hotremove (remove_memory): ret = walk_memory_range(PFN_DOWN(start), PFN_UP(start + size - 1), NULL, check_memblock_offlined_cb); if (ret) BUG(); it took us quite non-trivial time realize that the customer had force_remove enabled. Even if the BUG was removed here and we could propagate the error up the call chain it wouldn't help at all because then we would hit a crash or a memory corruption later and harder to debug. So force_remove is unfixable for the memory hotremove. We haven't checked other hotplugable resources to be prone to a similar problems. Remove the force_remove functionality because it is not fixable currently. Keep the sysfs file and report an error if somebody tries to enable it. Encourage users to report about the missing functionality and work with them with an alternative solution.

Please note that A-Device must input the following command if you want the board to act as a host again. # echo host > /sys/devices/platform/soc/ee020000.usb/role Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |

livepatch: change to a per-task consistency model
Change livepatch to use a basic per-task consistency model. This is the
foundation which will eventually enable us to patch those ~10% of
security patches which change function or data semantics. This is the
biggest remaining piece needed to make livepatch more generally useful.
This code stems from the design proposal made by Vojtech [1] in November
2014. It's a hybrid of kGraft and kpatch: it uses kGraft's per-task
consistency and syscall barrier switching combined with kpatch's stack
trace switching. There are also a number of fallback options which make
it quite flexible.
Patches are applied on a per-task basis, when the task is deemed safe to
switch over. When a patch is enabled, livepatch enters into a
transition state where tasks are converging to the patched state.
Usually this transition state can complete in a few seconds. The same
sequence occurs when a patch is disabled, except the tasks converge from
the patched state to the unpatched state.
An interrupt handler inherits the patched state of the task it
interrupts. The same is true for forked tasks: the child inherits the
patched state of the parent.
Livepatch uses several complementary approaches to determine when it's
safe to patch tasks:
1. The first and most effective approach is stack checking of sleeping
tasks. If no affected functions are on the stack of a given task,
the task is patched. In most cases this will patch most or all of
the tasks on the first try. Otherwise it'll keep trying
periodically. This option is only available if the architecture has
reliable stacks (HAVE_RELIABLE_STACKTRACE).
2. The second approach, if needed, is kernel exit switching. A
task is switched when it returns to user space from a system call, a
user space IRQ, or a signal. It's useful in the following cases:
a) Patching I/O-bound user tasks which are sleeping on an affected
function. In this case you have to send SIGSTOP and SIGCONT to
force it to exit the kernel and be patched.
b) Patching CPU-bound user tasks. If the task is highly CPU-bound
then it will get patched the next time it gets interrupted by an
IRQ.
c) In the future it could be useful for applying patches for
architectures which don't yet have HAVE_RELIABLE_STACKTRACE. In
this case you would have to signal most of the tasks on the
system. However this isn't supported yet because there's
currently no way to patch kthreads without
HAVE_RELIABLE_STACKTRACE.
3. For idle "swapper" tasks, since they don't ever exit the kernel, they
instead have a klp_update_patch_state() call in the idle loop which
allows them to be patched before the CPU enters the idle state.
(Note there's not yet such an approach for kthreads.)
All the above approaches may be skipped by setting the 'immediate' flag
in the 'klp_patch' struct, which will disable per-task consistency and
patch all tasks immediately. This can be useful if the patch doesn't
change any function or data semantics. Note that, even with this flag
set, it's possible that some tasks may still be running with an old
version of the function, until that function returns.
There's also an 'immediate' flag in the 'klp_func' struct which allows
you to specify that certain functions in the patch can be applied
without per-task consistency. This might be useful if you want to patch
a common function like schedule(), and the function change doesn't need
consistency but the rest of the patch does.
For architectures which don't have HAVE_RELIABLE_STACKTRACE, the user
must set patch->immediate which causes all tasks to be patched
immediately. This option should be used with care, only when the patch
doesn't change any function or data semantics.
In the future, architectures which don't have HAVE_RELIABLE_STACKTRACE
may be allowed to use per-task consistency if we can come up with
another way to patch kthreads.
The /sys/kernel/livepatch/<patch>/transition file shows whether a patch
is in transition. Only a single patch (the topmost patch on the stack)
can be in transition at a given time. A patch can remain in transition
indefinitely, if any of the tasks are stuck in the initial patch state.
A transition can be reversed and effectively canceled by writing the
opposite value to the /sys/kernel/livepatch/<patch>/enabled file while
the transition is in progress. Then all the tasks will attempt to
converge back to the original patch state.

First set of IIO new device support, features and cleanup for the 4.12 cycle.
Quite a bit of outreachy activity here with a driver from a current intern
and a number of cleanup patches as part of the next round.
Getting a pull request in early this cycle as it's looking like another large
cycle for IIO.
New device support
* adxl345
- initial device support. Note, once complete support is done the intent
is to superceded the driver in input/misc.
- bindings.
- conversion from i2c direct calls to regmap and driver split.
- spi support.
* chromeos light and proximity.
- new driver.
* devantech srf04 ultrasonic ranger
- new driver with device tree bindings.
* hid temperature
- new driver for environemntal temperature support from hid devices.
* max30102 oximeter
- new driver with device tree bindings.
* st lsm6dsx
- refactor and addition of device support for lsm6dsl and lsm6ds3h.
Staging graduation
* isl29028 including copyright notice update to reflect Brian's work.
* lpc32xx_adc.
* spear adc. It's not perfect and there are some datasheet disagreements, but
it works and is good enough to graduate.
New features
* documentation
- abi docs for in_proximity_sampling_frequency_available.
- generalise counting direction ABI docs as a second driver is going to
use them.
* hid-sensor-prox
- Add support for HID_USAGE_SENSOR_HUMAN_PRESENCE if used on a particular
device.
* isl29028
- runtime pm.
* meson-saradc
- switch from polling to interrupt mode and improved read_raw_sample function
to avoid unnecessary loop.
* tmp007
- interrupt and threshold event support.
Cleanups and minor fixes
* ad2s1210
- permissions to octal.
* ad7192
- permissions to octal.
- use BIT macro.
* ad9832
- merge header definitions into source file.
* ad9834
- merge header definitions into source file.
* ade7753
- merge header definitions into source file.
- cleanup include ordering.
*

zram: remove obsolete sysfs attrs
We had a deprecated_attr_warn() warning for 2 years and now the time has come and we finally can do the cleanup. The plan was as follows: : per-stat sysfs attributes are considered to be deprecated. : The basic strategy is: : -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11) : -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11) : : The list of deprecated attributes can be found here: : Documentation/ABI/obsolete/sysfs-block-zram : : Basically, every attribute that has its own read accessible sysfs : node (e.g. num_reads) *AND* is accessible via one of the stat files : (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered : to be deprecated. The patch also removes `obsolete/sysfs-block-zram', clean ups `testing/sysfs-block-zram' and tweaks zram.txt files.

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle

Add new entry to the RDMA-CM configfs that allows users to select default TOS for RDMA-CM QPs. This is useful for users that want to control the TOS for legacy applications without changing their code. Application that sets the TOS explicitly using the rdma_set_option API will continue to work as expected, meaning overriding the configfs value.

rtc: bq32000: add support to enable disable the trickle charge FET bypass
The bq32000 includes a trickle charge circuit to maintain the charge of the backup supply when a super capacitor is used. You can enable the charging circuit by setting 'trickle-resistor-ohms', additionally you can set TCFE to 1 to bypass the internal diode and boost the charge voltage of the backup supply. You might want to enable/disable the TCFE switch from userspace (e.g when device is only connected to a battery) This patch introduces a new sysfs entry to enable and disable this FET form userspace.

PM / devfreq: Simplify the sysfs name of devfreq-event device
This patch just removes '.' character from the sysfs name of devfreq-event
device as following. Usually, the subsystem uses the similiar naming style
such as {framework name}{Number}.
- old : /sys/class/devfreq-event/event.(X)
- new : /sys/class/devfreq-event/event(X)
And this patch initializes the value of 'event_no' with -1
in order to remove the unneeded operation (-1) when calling
the atomic_inc_return(&event_no).
Lastly, this patch adds the ABI document for devfreq-event class.

[media] rc: change wakeup_protocols to list all protocol variants
For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

leds: class: Add new optional brightness_hw_changed attribute
Some LEDs may have their brightness level changed autonomously (outside of kernel control) by hardware / firmware. This commit adds support for an optional brightness_hw_changed attribute to signal such changes to userspace (if a driver can detect them): What: /sys/class/leds/<led>/brightness_hw_changed Date: January 2017 KernelVersion: 4.11 Description: Last hardware set brightness level for this LED. Some LEDs may be changed autonomously by hardware/firmware. Only LEDs where this happens and the driver can detect this, will have this file. This file supports poll() to detect when the hardware changes the brightness. Reading this file will return the last brightness level set by the hardware, this may be different from the current brightness. Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to their flags field and call led_classdev_notify_brightness_hw_changed() with the hardware set brightness when they detect a hardware / firmware triggered brightness change.

iio: Add STM32 timer trigger driver
Timers IPs can be used to generate triggers for other IPs like DAC or ADC. Each trigger may result of timer internals signals like counter enable, reset or edge, this configuration could be done through "master_mode" device attribute. Since triggers could be used by DAC or ADC their names are defined in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger function could be used to check if the trigger is valid or not. "trgo" trigger have a "sampling_frequency" attribute which allow to configure timer sampling frequency. version 8: - change kernel version from 4.10 to 4.11 in ABI documentation version 7: - remove all iio_device related code - move driver into trigger directory version 5: - simplify tables of triggers - only create an IIO device when needed version 4: - get triggers configuration from "reg" in DT - add tables of triggers - sampling frequency is enable/disable when writing in trigger sampling_frequency attribute - no more use of interruptions version 3: - change compatible to "st,stm32-timer-trigger" - fix attributes access right - use string instead of int for master_mode and slave_mode - document device attributes in sysfs-bus-iio-timer-stm32 version 2: - keep only one compatible - use st,input-triggers-names and st,output-triggers-names to know which triggers are accepted and/or create by the device Signed-off-by: Benjamin Gaignard <benjamin.gaignard@st.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> |

First round of new device support, features and cleanups for IIO in the 4.11 cycle.
It's shaping to be another fairly busy cycle. Lots more on the way! New device support * ads7950 - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954, ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs. * cm3605 - New driver for this light sensor and proximity sensor which is an analog part with some additional digital controls. * hx711 - New driver. Core new stuff * Gravity sensor type. This is a processed datastream in which the device will try to work out which way is down. * Split the buffer.h file into two parts. One provides the interface to 'use' a buffer, the second provides the internals of the buffer functionality as needed by implementations of buffers. - Move documentation inline so as to allow use of private: tag when generating documentation. - Add some utility functions for the few things that are directly done with the buffers. - Stop exporting functions that no-one uses outside of the core code. - Push docs down by the code in the c file where they should have always been. - Fix typo in kernel-doc for buffer. - push down some includes that were previously happening implicitly. - stop enabling the timestamp of the dummy device. Features and cleanups * ad5592r - ACPI support * ad5593r -ACPI support. * ad5933 - Fix a false comment about size of a particular register. * ad7150 - replace S_IRUGO | S_IWUSR with 0644. I'm not that keen on these patches in general, but as it was nicely presented I took this one anyway. As a general rule will only take these as part of a larger driver cleanup. - don't eat an error but rather reutnr it in the write_event_config callback. * ad7606 - replace non standard range attibute with _scale * ade7753 - use usleep_range for short sleeps * ade7754 - use usleep_range for short sleeps * ade7758 - use usleep_range for short sleeps * ade7759 - use usleep_range for short sleeps * |

EDAC: Expose per-DIMM error counts in sysfs
The old csrowX sysfs directories have per-csrow error counters, but the new dimmX directories do not currently expose error counts. EDAC already keeps these counts, add them to sysfs so per-DIMM counts are still available when CONFIG_EDAC_LEGACY_SYSFS=n.

Merge branch 'x86-cache-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cache allocation interface from Thomas Gleixner:
"This provides support for Intel's Cache Allocation Technology, a cache
partitioning mechanism.
The interface is odd, but the hardware interface of that CAT stuff is
odd as well.
We tried hard to come up with an abstraction, but that only allows
rather simple partitioning, but no way of sharing and dealing with the
per package nature of this mechanism.
In the end we decided to expose the allocation bitmaps directly so all
combinations of the hardware can be utilized.
There are two ways of associating a cache partition:
- Task
A task can be added to a resource group. It uses the cache
partition associated to the group.
- CPU
All tasks which are not member of a resource group use the group to
which the CPU they are running on is associated with.
That allows for simple CPU based partitioning schemes.
The main expected user sare:
- Virtualization so a VM can only trash only the associated part of
the cash w/o disturbing others
- Real-Time systems to seperate RT and general workloads.
- Latency sensitive enterprise workloads
- In theory this also can be used to protect against cache side
channel attacks"
[ Intel RDT is "Resource Director Technology". The interface really is
rather odd and very specific, which delayed this pull request while I
was thinking about it. The pull request itself came in early during
the merge window, I just delayed it until things had calmed down and I
had more time.
But people tell me they'll use this, and the good news is that it is
_so_ specific that it's rather independent of anything else, and no
user is going to depend on the interface since it's pretty rare. So if
push comes to shove, we can just remove the interface and nothing will
break ]

sound updates for 4.10-rc1
No dramatic changes are found in this development cycle, but as usual,
many commits are applied in a wide range of drivers.
Most of big changes are in ASoC, where a few bits of framework work
and quite a lot of cleanups and improvements to existing code have
been done. The rest are usual stuff, a few HD-audio and USB-audio
quirks and fixes, as well as the drop of kthread usages in the whole
subsystem.
Below are some highlights:
ASoC:
- Support for stereo DAPM controls
- Some initial work on the of-graph sound card
- regmap conversions of the remaining AC'97 drivers
- A new version of the topology ABI; this should be backward compatible
- Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
Intel skylake, atom-sst
- New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
Realtek RT5665
USB-audio:
- Yet another race fix at disconnection
- Tolerated packet size calculation for some Android devices
- Quirks for Axe-Fx II, QuickCam, TEAC 501/503
HD-audio:
- Improvement of Dell pin fixup mapping
- Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
Misc:
- Replace all kthread usages with simple works

Char/Misc driver patches for 4.10-rc1

Driver core patches for 4.10-rc1
Here's the new driver core patches for 4.10-rc1. Big thing here is the nice addition of "functional dependencies" to the driver core. The idea has been talked about for a very long time, great job to Rafael for stepping up and implementing it. It's been tested for longer than the 4.9-rc1 date, we held off on merging it earlier in order to feel more comfortable about it. Other than that, it's just a handful of small other patches, some good cleanups to the mess that is the firmware class code, and we have a test driver for the deferred probe logic. All of these have been in linux-next for a while with no reported issues.

Staging/IIO patches for 4.10-rc1
Here's the "big" staging/iio pull request for 4.10-rc1.
Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver was
removed (got a "clean" driver for the same hardware through the netdev
tree), and some iio drivers were also dropped, but I think we ended up
adding a few thousand lines to the source tree in the end. Other than
that it's a lot of minor fixes all over the place, nothing major stands
out at all.
All of these have been in linux-next for a while. There will be a merge
conflict with Al's vfs tree in the lustre code, but the resolution for
that should be pretty simple, that too has been in linux-next.

Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-block
Pull block layer updates from Jens Axboe:
"This is the main block pull request this series. Contrary to previous
release, I've kept the core and driver changes in the same branch. We
always ended up having dependencies between the two for obvious
reasons, so makes more sense to keep them together. That said, I'll
probably try and keep more topical branches going forward, especially
for cycles that end up being as busy as this one.
The major parts of this pull request is:
- Improved support for O_DIRECT on block devices, with a small
private implementation instead of using the pig that is
fs/direct-io.c. From Christoph.
- Request completion tracking in a scalable fashion. This is utilized
by two components in this pull, the new hybrid polling and the
writeback queue throttling code.
- Improved support for polling with O_DIRECT, adding a hybrid mode
that combines pure polling with an initial sleep. From me.
- Support for automatic throttling of writeback queues on the block
side. This uses feedback from the device completion latencies to
scale the queue on the block side up or down. From me.
- Support from SMR drives in the block layer and for SD. From Hannes
and Shaun.
- Multi-connection support for nbd. From Josef.
- Cleanup of request and bio flags, so we have a clear split between
which are bio (or rq) private, and which ones are shared. From
Christoph.
- A set of patches from Bart, that improve how we handle queue
stopping and starting in blk-mq.
- Support for WRITE_ZEROES from Chaitanya.
- Lightnvm updates from Javier/Matias.
- Supoort for FC for the nvme-over-fabrics code. From James Smart.
- A bunch of fixes from a whole slew of people, too many to name
here"

VFIO updates for v4.10-rc1
- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing
this virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a
portion of a physical GPU. QEMU composes these mdevs into PCI
representations using the existing VFIO user API. This enables
both Intel KVM-GT support, which is also expected to arrive into
Linux mainline during the v4.10 merge window, as well as NVIDIA
vGPU, and also Channel I/O devices (aka CCW devices) for s390
virtualization support. (Kirti Wankhede, Neo Jia)
- Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)
- Fixes to VFIO capability chain handling (Eric Auger)
- Error handling fixes for fallout from mdev (Christophe JAILLET)
- Notifiers to expose struct kvm to mdev vendor drivers (Jike Song)
- type1 IOMMU model search fixes (Kirti Wankhede, Neo Jia)

Merge tag 'vfio-v4.10-rc1' of git://github.com/awilliam/linux-vfio
Pull VFIO updates from Alex Williamson:
- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing this
virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a portion
of a physical GPU. QEMU composes these mdevs into PCI representations
using the existing VFIO user API. This enables both Intel KVM-GT
support, which is also expected to arrive into Linux mainline during
the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O
devices (aka CCW devices) for s390 virtualization support. (Kirti
Wankhede, Neo Jia)
- Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)
- Fixes to VFIO capability chain handling (Eric Auger)
- Error handling fixes for fallout from mdev (Christophe JAILLET)
- Notifiers to expose struct kvm to mdev vendor drivers (Jike Song)
- type1 IOMMU model search fixes (Kirti Wankhede, Neo Jia)

remoteproc updates for v4.10
Introduces remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. Handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation. This ensures that all vrings for all virtio devices are allocated before we boot the remote processor. The debugfs mechanism for starting and stopping remoteproc instances was replaced with a sysfs interface, also providing a mechanism for specifying firmware to use by the instance. This allows user space to load and boot use case specific firmware on remote processors. New drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as removal of the unused StE modem loader. Finally support for crash recovery in the Qualcomm Wirelss subsystem (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes and cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJYTzfjAAoJEAsfOT8Nma3Fcs0P/irQd7U3gW14XFnl4ObdCOSO WlfG6jYP3fkWYA/ynxmu1FbRsyjP1aCrTRmW7oUGtTjCey8oUj69jo2+nLm0yx1k EtaTM+72hc7wULaGCBVvmA+LdQRRmTof9uJEjKvDyC8FAY0Thyvu77qlXQ5BrJkN o9xNVPDne/1RZx8vVI/zGEeL5+pNK1LXVy0vtFdG89acimu8yIJWJGS0IabnEWLs 8US6kpxROwkLefuTD4Rs4ByL6S5+1pHwVM6L/5GxsMawMzOhvzYgRa0SNNh7cNO/ e5ND7dUTcCt7lMOnpbSfqm2BbVRky6ATsoYrOdnVEH9sYJkQ9pMONadHIlVZFwce YVDp0UwEasf2IMtAFlvxDI31C5Wm8lpYOL7eixkkVrI1DJaBj8+Ih38F2IruWl9R QeDSFH/8a9l6fyN6RIUuPR8b1eeurl+CDoYWKEN6vzXDSi8GqsElB70xIAN/Umdq wdJvJByfitYLKEHenG5+mnQrDTQJ0C2f45hynkTCfJY1Qdl6nsMQi5sZFrE8HpOs dXFnpg/YK98wWmjyADEYDziH2y5oMHM6r5uljjcKOJDnzwLsDh8WQqhH4dNPNZBA 2+b4ouhbJLwYMM3zpem8JvV0rIsXvn3Kc8VNKcWOtHymkn8hLQ6Zexsr+RkbttQL Em5DvXL5lPm7wVYHvgP8 =/1kU -----END PGP SIGNATURE----- Merge tag 'rproc-v4.10' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: - introduce remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. - handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation.

block: add support for REQ_OP_WRITE_ZEROES
This adds a new block layer operation to zero out a range of LBAs. This allows to implement zeroing for devices that don't use either discard with a predictable zero pattern or WRITE SAME of zeroes. The prominent example of that is NVMe with the Write Zeroes command, but in the future, this should also help with improving the way zeroing discards work. For this operation, suitable entry is exported in sysfs which indicate the number of maximum bytes allowed in one write zeroes operation by the device.

PCI: Create revision file in sysfs
Currently the revision isn't available via sysfs/libudev thus if one wants to know the value one needs to read through the config file, which can be quite time-consuming because it wakes/powers up the device. There are at least two userspace components which could make use the new file: libpciaccess and libdrm. The former wakes up _every_ PCI device, which can be observed via glxinfo when using Mesa 10.0+ drivers. The latter, in association with Mesa 13.0, can lead to 2-3 second delays while starting firefox, thunderbird or chromium.

PM / sleep: System sleep state selection interface rework
There are systems in which the platform doesn't support any special
sleep states, so suspend-to-idle (PM_SUSPEND_FREEZE) is the only
available system sleep state. However, some user space frameworks
only use the "mem" and (sometimes) "standby" sleep state labels, so
the users of those systems need to modify user space in order to be
able to use system suspend at all and that may be a pain in practice.

phy: rcar-gen3-usb2: add sysfs for usb role swap
This patch adds sysfs "role" for usb role swap. This parameter can be read and write. If you use this file as the following, you can swap the usb role. For example: 1) Connect a usb cable using 2 Salvator-x boards 2) On A-Device (ID pin is low), you input the following command: # echo peripheral > /sys/devices/platform/soc/ee080200.usb-phy/role 3) On B-Device (ID pin is high), you input the following command: # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Then, the A-device acts as a peripheral and the B-device acts as a host. Please note that A-Device must input the following command if you want the board to act as a host again. (even if you disconnect the usb cable, since id state may be the same, the A-Device keeps to act as peripheral.) # echo host > /sys/devices/platform/soc/ee080200.usb-phy/role Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Reviewed-by: Peter Chen <peter.chen@nxp.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> |

Third set of IIO new device support, features and cleanup for the 4.10 cycle.
Includes Peter Rosin's interesting drivers for a comparator. First complex
use we have had with an analog front end made from discrete components.
Brian Masney's work on moving the tsl2583 driver out of staging also
feature extensively!
New Drivers
* DAC based on a digital potentiometer
- New driver for the use of a dpot as a DAC. Includes bindings and Axentia
entry in vendor prefixes.
* Envelope detector baed on DAC and a comparator including device tree
bindings.
Staging Graduation
* tsl2583.
Core new features
- Core provision for _available attributes. This one had been stalled for
a long time until Peter picked it up and ran with it!
- In kernel interface helpers to retrieve available info from channels.
Driver new features
* mcp4531
- Add range of available raw values (used for the dpot dac driver).
Driver cleanups and fixes for issues introduced
* ad7766
- Testing the wrong variable following devm_regulator_bulk_get introduced
with the driver earlier in this cycle.
* ad9832

Merge tag 'iio-for-4.10c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Third set of IIO new device support, features and cleanup for the 4.10 cycle.
Includes Peter Rosin's interesting drivers for a comparator. First complex
use we have had with an analog front end made from discrete components.
Brian Masney's work on moving the tsl2583 driver out of staging also
feature extensively!
New Drivers
* DAC based on a digital potentiometer
- New driver for the use of a dpot as a DAC. Includes bindings and Axentia
entry in vendor prefixes.
* Envelope detector baed on DAC and a comparator including device tree
bindings.
Staging Graduation
* tsl2583.
Core new features
- Core provision for _available attributes. This one had been stalled for
a long time until Peter picked it up and ran with it!
- In kernel interface helpers to retrieve available info from channels.
Driver new features
* mcp4531
- Add range of available raw values (used for the dpot dac driver).
Driver cleanups and fixes for issues introduced
* ad7766
- Testing the wrong variable following devm_regulator_bulk_get introduced
with the driver earlier in this cycle.
* ad9832
- Fix a wrong ordering in the probe introduced in the previous set of
patches. A use before allocation bug.
* cros_ec_sensors
- Testing for an error in a u8 will never work.
* mpu3050
- Remove duplicate initializer for the module owner.
- Add missing i2c dependency.

iio: envelope-detector: ADC driver based on a DAC and a comparator
The DAC is used to find the peak level of an alternating voltage input
signal by a binary search using the output of a comparator wired to
an interrupt pin. Like so:
