platform-drivers-x86 for v4.19-1
The driver for Silead touchscreen configurations has been renamed from silead_dmi to touchscreen_dmi since it starts supporting other touchscreens which require some DMI quirks. At the same release cycle it gets expanded to cover cases for Chuwi Vi10, ONDA V891W, Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets. Another bunch of changes is related to Mellanox platform code to allow user space to communicate with Mellanox for system control and monitoring purposes. The driver notifies user on hotplug device signal receiving. ASUS WMI drivers recognize lid flip action on UX360, and correctly toggles airplane mode LED. In addition the keyboard backlight toggle gets support. ThinkPad ACPI driver enables support for calculator key (on at least P52). It also has been fixed to support three characters model designators, which are used for modern laptops. Earlier the battery, marked as BAT1, on ThinkPad laptops has not been configured properly, which is fixed. On the opposite the multi-battery configurations now probed correctly. Dell SMBIOS driver starts working on some Dell servers which do not support token interface. The regression with backlight detection has also been fixed. In order to support dock mode on some laptops, Intel virtual button driver has been fixed. The last but not least is the fix to Intel HID driver due to changes in Dell systems that prevented to use power button. The following is an automated git shortlog grouped by driver: acer-wmi: - Silence "unsupported" message a bit - refactor function has_cap asus-nb-wmi: - Add keymap entry for lid flip action on UX360 asus-wireless: - Fix uninitialized symbol usage - Toggle airplane mode LED asus-wmi: - Add keyboard backlight toggle support - Call led hw_changed API on kbd brightness change dell-laptop: - Fix backlight detection dell-smbios: - make a function and a pointer static dell-smbios-base: - Support systems without tokens dell-smbios-wmi: - make function dell_smbios_wmi_call static ideapad-laptop: - Add Y520-15IKBM and Y720-15IKBM to no_hw_rfkill - Apply no_hw_rfkill to Y20-15IKBM, too intel-hid: - Add support for Device Specific Methods intel_ips: - remove redundant variables slope and offset intel_pmc_core: - Add CNP SLPS0 debug registers intel_punit_ipc: - fix build errors intel-vbtn: - Add support for dock mode detection mlx-platform: - Fix copy-paste error in mlxplat_init() - Remove unused define - Change mlxreg-io configuration for MSN274x systems - Allow mlxreg-io driver activation for more systems - Add ASIC hotplug device configuration - Add new attribute for mlxreg-io sysfs interfaces - Add mlxreg-fan platform driver activation - Add documentation mlxreg-io sysfs interfaces - Add mlxreg-io platform driver activation platform/mellanox: - mlxreg-hotplug: Add hotplug hwmon uevent notification - mlxreg-hotplug: Improve mechanism of ASIC health discovery - Use 2-factor allocator calls - Introduce support for Mellanox register access driver thinkpad_acpi: - Fix multi-battery bug - extend battery quirk coverage - Support battery quirk - Proper model/release matching - Add support for calculator hotkey toshiba_acpi: - Fix defined but not used build warnings - Update KBD backlight LED on second gen laptops touchscreen_dmi: - Rename silead_dmi to touchscreen_dmi - Add touchscreen info for the Chuwi Vi10 tablet - Sort entries alphabetically - Rename trekstor entries - Add info for the Cube KNote i1101 tablet - Add info for the Onda V820w tablet - Add info for the "Connect Tablet 9" tablet - Add info for the ONDA V891W Dual OS tablet wmi: - Do not mix pages and kmalloc -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEhiZOUlnC9oKN3n3AmT3/83c5Sy0FAlt9wVgACgkQmT3/83c5 Sy3Jdg//WnEJZx7+zEsO+3dJnQGN4Fur6xhP79subRhZPFNTZ+D5vMHC9DL8ZQYx U8Kz1ilxCC5HuOo2S1BlzRG+h6ztMSYIFo2H8KRdygOqALEH7hoStPEGYdZcQ0qE 6SKa4MnRw46UcGPij3f6STPiOjicPaLoUSTXZmi2dbmy6sJZMMJamvnRhezgEgJl rA6xvg+tKNBK2jwLpAVfLhy4Btd6LCE4EGgkYdnytOM9ByHLDsTWCZxd/9h7WjPa L8Zd8rftrazWF6X2tAhpXtUcMPg/D4lfL5HHaMmL9FioycQ88WqDBZN5sEWdIbaP OfaMbcbhCIrrHoMNdq0544IgqRQahX+m3VjSkVf3/Aj5AU0nUJMBWSpGHAs7UCSN 8i8M2jdpVW7CVxA+4OU2l19udKrQzXutfXXhVYX0B3hKCkH7TBKax+m/ev9n2yvZ KoTdSJ/4bB6iGhXF8/MA6H72k0g972d4WXozbTusiBO9grqgU1EIe5bYZ4y+FkJL 9gtK1xgtDJB7J8U14lpGC+zKhcYn1Mn3Iq4i5HD3sfnKsVGGWJIjRZsDtALD2RKT OQe7S8xhQWqsUZFGNflWL+8oHyXOHGD5Q8b/YI92ubriyAzh3I3Ybt/atk20vdmG QfKU46suOoOUwcAs00v13oo+9s9GatekXEjGgdRJ14vgzdgx3lc= =vRud -----END PGP SIGNATURE----- Merge tag 'platform-drivers-x86-v4.19-1' of git://git.infradead.org/linux-platform-drivers-x86 Pull x86 platform driver updates from Andy Shevchenko: - The driver for Silead touchscreen configurations has been renamed from silead_dmi to touchscreen_dmi since it starts supporting other touchscreens which require some DMI quirks It also gets expanded to cover cases for Chuwi Vi10, ONDA V891W, Connect Tablet 9, Onda V820w, and Cube KNote i1101 tablets. - Another bunch of changes is related to Mellanox platform code to allow user space to communicate with Mellanox for system control and monitoring purposes.

platform/x86: acer-wmi: Silence "unsupported" message a bit
This driver prints that "Unsupported machine..." message on every boot on ThinkPad X1 Carbon laptops (and I assume a number of other systems), which causes graphical boots to "glitch" a bit and is rather annoying ... Make it a pr_debug instead. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> |

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull core signal handling updates from Eric Biederman:
"It was observed that a periodic timer in combination with a
sufficiently expensive fork could prevent fork from every completing.
This contains the changes to remove the need for that restart.
This set of changes is split into several parts:
- The first part makes PIDTYPE_TGID a proper pid type instead
something only for very special cases. The part starts using
PIDTYPE_TGID enough so that in __send_signal where signals are
actually delivered we know if the signal is being sent to a a group
of processes or just a single process.
- With that prep work out of the way the logic in fork is modified so
that fork logically makes signals received while it is running
appear to be received after the fork completes"

Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level
hardware bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of
the crazy out-of-tree drivers that have been floating around
for years, combined with some really hacky userspace
implementations. This is only for GNSS receivers, but you
have to start somewhere, and this is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and existing
drivers.
Full details of everything is in the shortlog.
All of these have been in linux-next for a while with no reported
issues.

Here are the main MIPS changes for 4.19.
An overview of the general architecture changes:
- Massive DMA ops refactoring from Christoph Hellwig (huzzah for
deleting crufty code!).
- We introduce NT_MIPS_DSP & NT_MIPS_FP_MODE ELF notes & corresponding
regsets to expose DSP ASE & floating point mode state respectively,
both for live debugging & core dumps.
- We better optimize our code by hard-coding cpu_has_* macros at
compile time where their values are known due to the ISA revision
that the kernel build is targeting.
- The EJTAG exception handler now better handles SMP systems, where it
was previously possible for CPUs to clobber a register value saved
by another CPU.
- Our implementation of memset() gained a couple of fixes for MIPSr6
systems to return correct values in some cases where stores fault.
- We now implement ioremap_wc() using the uncached-accelerated cache
coherency attribute where supported, which is detected during boot,
and fall back to plain uncached access where necessary. The
MIPS-specific (and unused in tree) ioremap_uncached_accelerated() &
ioremap_cacheable_cow() are removed.
- The prctl(PR_SET_FP_MODE, ...) syscall is better supported for SMP
systems by reworking the way we ensure remote CPUs that may be
running threads within the affected process switch mode.
- Systems using the MIPS Coherence Manager will now set the
MIPS_IC_SNOOPS_REMOTE flag to avoid some unnecessary cache
maintenance overhead when flushing the icache.
- A few fixes were made for building with clang/LLVM, which
now sucessfully builds kernels for many of our platforms.
- Miscellaneous cleanups all over.
And some platform-specific changes:
- ar7 gained stubs for a few clock API functions to fix build failures
for some drivers.
- ath79 gained support for a few new SoCs, a few fixes & better
gpio-keys support.
- Ci20 now exposes its SPI bus using the spi-gpio driver.
- The generic platform can now auto-detect a suitable value for
PHYS_OFFSET based upon the memory map described by the device tree,
allowing us to avoid wasting memory on page book-keeping for systems
where RAM starts at a non-zero physical address.
- Ingenic systems using the jz4740 platform code now link their
vmlinuz higher to allow for kernels of a realistic size.
- Loongson32 now builds the kernel targeting MIPSr1 rather than MIPSr2
to avoid CPU errata.
- Loongson64 gains a couple of fixes, a workaround for a write
buffering issue & support for the Loongson 3A R3.1 CPU.
- Malta now uses the piix4-poweroff driver to handle powering down.
- Microsemi Ocelot gained support for its SPI bus & NOR flash, its
second MDIO bus and can now be supported by a FIT/.itb image.
- Octeon saw a bunch of header cleanups which remove a lot of
duplicate or unused code.

platform/x86: Add ACPI i2c-multi-instantiate pseudo driver
On systems with ACPI instantiated i2c-clients, normally there is 1 fw_node per i2c-device and that fw-node contains 1 I2cSerialBus resource for that 1 i2c-device. But in some rare cases the manufacturer has decided to describe multiple i2c-devices in a single ACPI fwnode with multiple I2cSerialBus resources. An earlier attempt to fix this in the i2c-core resulted in a lot of extra code to support this corner-case. This commit introduces a new i2c-multi-instantiate driver which fixes this in a different way. This new driver can be built as a module which will only loaded on affected systems. This driver will instantiate a new i2c-client per I2cSerialBus resource, using the driver_data from the acpi_device_id it is binding to to tell it which chip-type (and optional irq-resource) to use when instantiating. Note this driver depends on a platform device being instantiated for the ACPI fwnode, see the i2c_multi_instantiate_ids list of ACPI device-ids in drivers/acpi/scan.c: acpi_device_enumeration_by_parent().

platform/mellanox: mlxreg-hotplug: Improve mechanism of ASIC health discovery
Simplify the logic of ASIC health discovery. ASIC device can indicate its health state as a good, booting or dormant. During ASIC reset the device is dropped to dormant state and should get to the stable good health state through the intermediate booting state. The sequence for getting to the steady state health after reset is: (dormant -> booting -> good)+. Initial implementation assumes that ?good? within this sequence is always repeated twice and device is getting steady state only after the second ?good?. This patch removes this dependency, since the second ?good? is received because of the noise on line and can be ignored. Device reaches steady state after the first ?good? is received.

The Dell laptop ACPI video brightness control is not present on dell
laptops anymore, but was present in older kernel versions.
The code that checks the return value is incorrect since the SMM

The old code was:
if (buffer->output[0] == 0)
Which was changed to:
ret = dell_send_request(...)
if (ret)
However, dell_send_request() will return 0 if buffer->output[0] == 0,
so we must change the check to:

PCI: hotplug: Demidlayer registration with the core
When a hotplug driver calls pci_hp_register(), all steps necessary for
registration are carried out in one go, including creation of a kobject
and addition to sysfs. That's a problem for pciehp once it's converted
to enable/disable the slot exclusively from the IRQ thread: The thread
needs to be spawned after creation of the kobject (because it uses the
kobject's name), but before addition to sysfs (because it will handle
enable/disable requests submitted via sysfs).
pci_hp_deregister() does offer a ->release callback that's invoked
after deletion from sysfs and before destruction of the kobject. But
because pci_hp_register() doesn't offer a counterpart, hotplug drivers'
->probe and ->remove code becomes asymmetric, which is error prone
as recently discovered use-after-free bugs in pciehp's ->remove hook
have shown.
In a sense, this appears to be a case of the midlayer antipattern:
"The core thesis of the "midlayer mistake" is that midlayers are
bad and should not exist. That common functionality which it is
so tempting to put in a midlayer should instead be provided as
library routines which can [be] used, augmented, or ignored by
each bottom level driver independently. Thus every subsystem
that supports multiple implementations (or drivers) should
provide a very thin top layer which calls directly into the
bottom layer drivers, and a rich library of support code that
eases the implementation of those drivers. This library is
available to, but not forced upon, those drivers."
-- Neil Brown (2009), https://lwn.net/Articles/336262/
The presence of midlayer traits in the PCI hotplug core might be ascribed
to its age: When it was introduced in February 2002, the blessings of a
library approach might not have been well known:
https://git.kernel.org/tglx/history/c/a8a2069f432c
For comparison, the driver core does offer split functions for creating
a kobject (device_initialize()) and addition to sysfs (device_add()) as
an alternative to carrying out everything at once (device_register()).
This was introduced in October 2002:
https://git.kernel.org/tglx/history/c/8b290eb19962
The odd ->release callback in the PCI hotplug core was added in 2003:
https://git.kernel.org/tglx/history/c/69f8d663b595
Clearly, a library approach would not force every hotplug driver to
implement a ->release callback, but rather allow the driver to remove
the sysfs files, release its data structures and finally destroy the
kobject. Alternatively, a driver may choose to remove everything with
pci_hp_deregister(), then release its data structures.
To this end, offer drivers pci_hp_initialize() and pci_hp_add() as a
split-up version of pci_hp_register(). Likewise, offer pci_hp_del()
and pci_hp_destroy() as a split-up version of pci_hp_deregister().
Eliminate the ->release callback and move its code into each driver's
teardown routine.
Declare pci_hp_deregister() void, in keeping with the usual kernel
pattern that enablement can fail, but disablement cannot. It only
returned an error if the caller passed in a NULL pointer or a slot which
has never or is no longer registered or is sharing its name with another
slot. Those would be bugs, so WARN about them. Few hotplug drivers
actually checked the return value and those that did only printed a
useless error message to dmesg. Remove that.
For most drivers the conversion was straightforward since it doesn't
matter whether the code in the ->release callback is executed before or
after destruction of the kobject. But in the case of ibmphp, it was
unclear to me whether setting slot_cur->ctrl and slot_cur->bus_on to
NULL needs to happen before the kobject is destroyed, so I erred on
the side of caution and ensured that the order stays the same. Another
nontrivial case is pnv_php, I've found the list and kref logic difficult
to understand, however my impression was that it is safe to delete the
list element and drop the references until after the kobject is
destroyed.

So, move the I2C and SPI transport drivers to the platform/chrome directory. The patch also removes the MFD_ prefix of their Kconfig symbols.

goldfish_pipe: make tasklet goldfish_interrupt_tasklet static
Tasklet goldfish_interrupt_tasklet is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: symbol 'goldfish_interrupt_tasklet' was not declared. Should it be static? Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

platform/x86: asus-wireless: Fix uninitialized symbol usage
'ret' will not be initialized if acpi_evaluate_integer() returns through
an error path, so it should not be used in this case. This fixes the
following Smatch static analyser error:
drivers/platform/x86/asus-wireless.c:76 asus_wireless_method() error:
uninitialized symbol 'ret'.

platform/x86: intel-vbtn: Add support for dock mode detection
The Dell laptop I have has an ACPI that sends 0xCB and 0xCC on entering tablet mode. On exiting tablet mode it sends 0xCA and 0xCD. Based on: http://www.traby.de/medion/DSDT/dsdt.dsl https://gist.github.com/jprvita/5737de3cbb670e80973b7d4e51c38ab6 https://osdn.net/projects/android-x86/scm/git/kernel/commits/ 7cbe5a330687b851f32dd9f1048a6ce182d0ff44 It appears that 0xCA and 0xCB are about dock mode, which for my convertible laptop seems questionably tied to whether I've put the laptop in tablet or laptop mode. I previously proposed no-oping 0xCA and 0xCB but this revised change attempts to add support for detecting dock mode--this detection will essentially be broken for my laptop (the main workaround would be for 0xCA and 0xCB to be used to provoke a query of the VGBS method that reports the current dock & tablet mode [which is accurately reported on my laptop but based on the prior workarounds in the driver it apparently can't be trusted for all systems]).

platform/x86: intel-hid: Add support for Device Specific Methods
In some of the recent platforms, it is possible that stand alone methods for HEBC() or other methods used in this driver may not exist. In this case intel-hid driver will fail to load and power button will not be functional. It is also possible that some quirks in this driver added for some platforms may have same issue in loading intel-hid driver. There is an update to the ACPI details for the HID event filter driver. In the updated specification a _DSM is added, which has separate function indexes for each of the previous stand alone methods. This change brings in support for the _DSM and allows usage of function index for corresponding stand alone methods. Details of Device Specific Method: Intel HID Event Filter Driver _DSM UUID: eeec56b3-4442-408f-a792-4edd4d758054 • Function index 0: Returns a buffer with a bit-field representing the supported function IDs. Function Index ASL Object -------------------------------- 1 BTNL 2 HDMM 3 HDSM 4 HDEM 5 BTNS 6 BTNE 7 HEBC 8 VGBS 9 HEBC One significant change is to query the supported methods implemented on the platform. So the previous HEBC() has two variants. HEBC v1 and HEBC v2. The v2 version allowed further define which of the 5-button are actually defined by the platform. HEBC v2 support is only available via new DSM. v1 Button details: Bits [0] - Rotation Lock, Num Lock, Home, End, Page Up, Page Down Bits [1] - Wireless Radio Control Bits [2] - System Power Down Bits [3] - System Hibernate Bits [4] - System Sleep/ System Wake Bits [5] - Scan Next Track Bits [6] - Scan Previous Track Bits [7] - Stop Bits [8] - Play/Pause Bits [9] - Mute Bits [10] - Volume Increment Bits [11] - Volume Decrement Bits [12] - Display Brightness Increment Bits [13] - Display Brightness Decrement Bits [14] - Lock Tablet Bits [15] - Release Tablet Bits [16] - Toggle Bezel Bits [17] - 5 button array Bits [18-31] - reserved v2 Buttom details: Bits [0-16] - Same as v1 version Bits [17] - 5 button array Bits [18] – Power Button Bits [19] - W Home Button Bits [20] - Volume Up Button Bits [21] - Volume Down Button Bits [22] – Rotation Lock Button Bits [23-31] – reserved Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Tested-by: Mario Limonciello <mario.limonciello@dell.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> |
