Jonathan Cameron d403719eeb dt-bindings:iio:cdc:adi,ad7150 binding doc
Binding covering the ad7150, ad7151 and ad7156 capacitance to digital
convertors.  The only difference between these is how many channels they
have (1 or 2)

Whilst it is clearly necessary to provide power to the part, we don't
need to know the voltage or anything so if it is always on, there should
be no need to have it specified in the binding.

Jonathan Cameron 9b2571b02d iio:Documentation:ABI Add missing elements as used by the adi,ad7150
Main additions are around thresh_adaptive.  This has been supported
by the core of IIO for a long time, but no driver that uses it has
previously graduated from staging, hence we are missing Docs.

Otherwise, just new entries in existing lists.

Greg Kroah-Hartman 9c15db92a8 1st set of IIO/counter device support, features and cleanup in the 5.13 cycle
Big set in here from Alexandru Ardelean enabling multiple buffer support.
 This includes providing a new directory per buffer that combines
 what was previously in buffer/ and scan_elements/. Old interfaces still
 in place for compatiblity.
 
 Note immuatable branch for scmi patches to allow for some significant
 rework going on in that subsystem.  Merge required updating to reflect
 some changes in IIO.
 
 Late rebase to fix some wrong fixes tags due to some earlier rebases
 made necessary by messing up the immutable branch.
 
 IIO New Device Support
 * adi,ad5686
   - Add info to support AD5673R and AD5677R
 * bosch,bmi088
   - New driver supporting this accelerometer + gyroscope
 * cros_ec_mkbp
   - New driver for this proximity sensor that exposes a 'front'
     sensor. Very simple switch like device, but driver allows it
     to share interface with more sophisticated proximity sensors.
 * iio_scmi
   - New driver to support ARM SCMI protocol to expose underlying
     accelerometers and gyroscopes via this firmware interface.
 * st,st_magn
   - Add ID for IISMDC magnetometer.
 * ti,ads131e0
   - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs
 
 Counter New Device Support
 * IRQ or GPIO based counter
   - New driver for a conceptually simple counter that uses interrupts
     to perform the count.
 
 Features
 * core
   - Dual buffer supprt including:
      Various helpers to centralize handling of bufferer related elements.
      Document existing and new IOCTLs
      Register the IIO chrdev only if it can actually be used for anything.
      Rework attribute group creation in the core (lots of patches)
      Merge buffer/ and scan_elements/ entries into one list + maintain
      backwards compatible set.
      Introduce the internal logic and IOCTL to allow multiple buffers
      + access to an anon FD per buffer to actually read from it.
      Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
      Update ABI docs.
      A few follow up fixes, unsuprising as this was a huge bit of rework.
   - Move common case setting of trig->parent to the core.
   - Provide an iio_read_channel_processed_scale() to avoid loss of
     precision from iio_read_channel_processed() then applying integer
     scale. Use it in ntc_thermistor driver in hwmon.
   - Allow drivers to specify labels from elsewhere than DT. Use it for
     bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
   - Document label usage for proximity and accelerometer sensors.
   - Some local variable renames for consistency
 tools
   - Add -a parameter to iio_event_monitor to allow autoenabling of events.
 * acpi_als
   - Add trigger support for devices that don't support notification method.
 * adi,ad7124
   - Allow more than 8 channels.  This is a complex little device, but is
     capable of supporting up to 16 channels if the share certain
     configuration settings.
 * hrtimer-trigger
   - Support sampling frequency below 1Hz.
 * mediatek,mt8195-auxadc
   - Add compatible to binding docs (always also includes mt8173)
 * st,stm32-adc
   - Enable timetamps when not using DMA.
 * vishay,vcnl3020
   - Sampling frequency control.
 
 Cleanup and minor fixes:
 * treewide
   - Use some getter and setter functions instead of opencoding.
   - Set of fixes for pointless casts in various drivers.
   - Avoid wrong kernel-doc marking on comment blocks.
   - Fix various other minor kernel-doc issues shown by W=1
 * core
   - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
   - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
   - Add unit tests for iio_format_value()
 * docs
   - Fix formatting/typos in iio_configfs.rst and buffers.rst
   - Add documentation of index in buffers.rst
   - Fix scan element description
   - Avoid some issues with HTML generation from ABI docs by moving
     duplicated defintions to more generic files.
   - Drop reference to long dead mailing list.
 * 104-quad
   - Remove left over deprecated IIO counter ABI.
 * adi,adi-axi-adc
   - Fix wrong bit of docs.

     on sysfs based configuration rather than getting from DT. Drop now
     unnecessary property from DT bindings doc.
 * cros_ec
    - Fix result of a series of recent changes that means extended buffer
      attributes turn up in the wrong place. Too complex to revert the
      various patches unfortunately so this is a bit messy.

This control on the gain of a measurement used for time of flight sensing
is standard but the expected values for different enviroments may not be.
As we cannot have the same ABI element documented in two files, add a

Sean Christopherson b318e8decf KVM: x86: Protect userspace MSR filter with SRCU, and set atomically-ish
Fix a plethora of issues with MSR filtering by installing the resulting
filter as an atomic bundle instead of updating the live filter one range
at a time.  The KVM_X86_SET_MSR_FILTER ioctl() isn't truly atomic, as
the hardware MSR bitmaps won't be updated until the next VM-Enter, but
the relevant software struct is atomically updated, which is what KVM
really needs.

Similar to the approach used for modifying memslots, make arch.msr_filter
a SRCU-protected pointer, do all the work configuring the new filter
outside of kvm->lock, and then acquire kvm->lock only when the new filter
has been vetted and created.  That way vCPU readers either see the old
filter or the new filter in their entirety, not some half-baked state.

Yuan Yao pointed out a use-after-free in ksm_msr_allowed() due to a
TOCTOU bug, but that's just the tip of the iceberg...

  - Nothing is __rcu annotated, making it nigh impossible to audit the
    code for correctness.
  - kvm_add_msr_filter() has an unpaired smp_wmb().  Violation of kernel
    coding style aside, the lack of a smb_rmb() anywhere casts all code
    into doubt.
  - kvm_clear_msr_filter() has a double free TOCTOU bug, as it grabs
    count before taking the lock.
  - kvm_clear_msr_filter() also has memory leak due to the same TOCTOU bug.

The entire approach of updating the live filter is also flawed.  While
installing a new filter is inherently racy if vCPUs are running, fixing
the above issues also makes it trivial to ensure certain behavior is
deterministic, e.g. KVM can provide deterministic behavior for MSRs with
identical settings in the old and new filters.  An atomic update of the
filter also prevents KVM from getting into a half-baked state, e.g. if
installing a filter fails, the existing approach would leave the filter
in a half-baked state, having already committed whatever bits of the
filter were already processed.

Marc Zyngier 7d717558dd KVM: arm64: Reject VM creation when the default IPA size is unsupported
KVM/arm64 has forever used a 40bit default IPA space, partially
due to its 32bit heritage (where the only choice is 40bit).

However, there are implementations in the wild that have a *cough*
much smaller *cough* IPA space, which leads to a misprogramming of
VTCR_EL2, and a guest that is stuck on its first memory access
if userspace dares to ask for the default IPA setting (which most
VMMs do).

Instead, blundly reject the creation of such VM, as we can't
satisfy the requirements from userspace (with a one-off warning).
Also clarify the boot warning, and document that the VM creation
will fail when an unsupported IPA size is provided.

Although this is an ABI change, it doesn't really change much
for userspace:

- the guest couldn't run before this change, but no error was
  returned. At least userspace knows what is happening.

- a memory slot that was accepted because it did fit the default
  IPA space now doesn't even get a chance to be registered.

The other thing that is left doing is to convince userspace to
actually use the IPA space setting instead of relying on the
antiquated default.

Hans de Goede 9a6df4b1ab iio: documentation: Document accelerometer label use
Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges,
have 2 accelerometers, 1 in their base and 1 in their display.

In many cases the kernel can detect the location of each accelerometer
based on e.g. information from the ACPI tables.

It is important for userspace to know the location of the 2 accelerometers.
Rather then adding a new sysfs-attribute for this we can relay this
information to userspace by using standardized label strings for this.
This mirrors how this is done for proximity sensors.

This commit documents 2 new standardized label strings for this purpose:
"accel-base"
"accel-display"

Note the "base" and "display" suffixes were chosen to match the values
used for the systemd/udev hwdb.d/60-sensor.hwdb file's ACCEL_LOCATION
property.

Hans de Goede 6505dfab33 iio: documentation: Document proximity sensor label use
Add an entry to Documentation/ABI/testing/sysfs-bus-iio for
the new device label sysfs-attribute support.

And document the standardized labels which may be used with proximity
sensors to hint userspace about the intended use of the sensor.

Using labels to differentiate between the multiple proximity sensors
which a modern laptop/tablet may have was discussed in this thread:
https://lore.kernel.org/linux-iio/9f9b0ff6-3bf1-63c4-eb36-901cecd7c4d9@redhat.com/

As mentioned there the "proximity-wifi*" labels are already being used
in this manner on some chromebooks, see e.g.:
arch/arm64/boot/dts/qcom/sc7180-trogdor.dtsi
arch/arm64/boot/dts/qcom/sc7180-trogdor-lte-sku.dtsi

And the "proximity-palmrest" and "proximity-lap" labels are intended
to be used with the lap and palmrest sensors found in recent Lenovo
ThinkPad models.

Currently, only the 'i' 0x90 ioctl() actually exists and is defined in

It's the IIO_GET_EVENT_FD_IOCTL, which is used to retrieve and FD for
reading events from an IIO device.
We will want to add more ioct() numbers, so with this change the 'i'
0x90-0x9F space is reserved for IIO ioctl() calls.

Alexandru Ardelean a02c09e42b iio: buffer-dma,adi-axi-adc: introduce devm_iio_dmaengine_buffer_setup()
This change does a conversion of the devm_iio_dmaengine_buffer_alloc() to
devm_iio_dmaengine_buffer_setup(). This will allocate an IIO DMA buffer and
attach it to the IIO device, similar to devm_iio_triggered_buffer_setup()
(though the underlying code is different, the final logic is the same).

Since the only user of the devm_iio_dmaengine_buffer_alloc() was the
adi-axi-adc driver, this change does the replacement in a single go in the
driver.

At this point all drivers should use devm_iio_kfifo_buffer_setup() instead
of manually allocating via devm_iio_kfifo_allocate() and assigning ops and
modes.

With this change, the devm_iio_kfifo_allocate() will be made private to the
IIO core, since all drivers should call either
devm_iio_kfifo_buffer_setup() or devm_iio_triggered_buffer_setup() to
create a kfifo buffer.

Alexandru Ardelean e36db6a069 iio: kfifo: add devm_iio_kfifo_buffer_setup() helper
This change adds the devm_iio_kfifo_buffer_setup() helper/short-hand,
which groups the simple routine of allocating a kfifo buffers via
devm_iio_kfifo_allocate() and calling iio_device_attach_buffer().

The mode_flags parameter is required, as the IIO kfifo supports 2 modes:
INDIO_BUFFER_SOFTWARE & INDIO_BUFFER_TRIGGERED.
The setup_ops parameter is optional.

This function will be a bit more useful when needing to define multiple
buffers per IIO device.

The naming for this function has been inspired from
iio_triggered_buffer_setup() since that one does a kfifo alloc + a pollfunc
alloc. So, this should have a more familiar ring to what it is.

Thomas Zimmermann 659ab7a49c drm: Use USB controller's DMA mask when importing dmabufs
USB devices cannot perform DMA and hence have no dma_mask set in their
device structure. Therefore importing dmabuf into a USB-based driver
fails, which breaks joining and mirroring of display in X11.

For USB devices, pick the associated USB controller as attachment device.
This allows the DRM import helpers to perform the DMA setup. If the DMA
controller does not support DMA transfers, we're out of luck and cannot
import. Our current USB-based DRM drivers don't use DMA, so the actual
DMA device is not important.

Tested by joining/mirroring displays of udl and radeon under Gnome/X11.

v8:
	* release dmadev if device initialization fails (Noralf)
	* fix commit description (Noralf)
v7:
	* fix use-before-init bug in gm12u320 (Dan)
v6:
	* implement workaround in DRM drivers and hold reference to
	  DMA device while USB device is in use
	* remove dev_is_usb() (Greg)
	* collapse USB helper into usb_intf_get_dma_device() (Alan)
	* integrate Daniel's TODO statement (Daniel)
	* fix typos (Greg)
v5:

	* add FIXME item to documentation and TODO list (Daniel)
v4:
	* implement workaround with USB helper functions (Greg)
	* use struct usb_device->bus->sysdev as DMA device (Takashi)
v3:
	* drop gem_create_object
	* use DMA mask of USB controller, if any (Daniel, Christian, Noralf)
v2:
	* move fix to importer side (Christian, Daniel)
	* update SHMEM and CMA helpers for new PRIME callbacks

David Woodhouse 30b5c851af KVM: x86/xen: Add support for vCPU runstate information
This is how Xen guests do steal time accounting. The hypervisor records
the amount of time spent in each of running/runnable/blocked/offline
states.

In the Xen accounting, a vCPU is still in state RUNSTATE_running while
in Xen for a hypercall or I/O trap, etc. Only if Xen explicitly schedules
does the state become RUNSTATE_blocked. In KVM this means that even when
the vCPU exits the kvm_run loop, the state remains RUNSTATE_running.

The VMM can explicitly set the vCPU to RUNSTATE_blocked by using the
KVM_XEN_VCPU_ATTR_TYPE_RUNSTATE_CURRENT attribute, and can also use
KVM_XEN_VCPU_ATTR_TYPE_RUNSTATE_ADJUST to retrospectively add a given
amount of time to the blocked state and subtract it from the running
state.

The state_entry_time corresponds to get_kvmclock_ns() at the time the
vCPU entered the current state, and the total times of all four states
should always add up to state_entry_time.

Joseph Qi 4168a8d27e block/bfq: update comments and default value in docs for fifo_expire
Correct the comments since bfq_fifo_expire[0] is for async request,
while bfq_fifo_expire[1] is for sync request.
Also update docs, according the source code, the default
fifo_expire_async is 250ms, and fifo_expire_sync is 125ms.
