Anish Bhatt ed45d40369 kbuild : Fix documentation of INSTALL_HDR_PATH
The header install makefile creates an 'include' directory inside
INSTALL_HDR_PATH and appending include to the path results in headers
being installed to include/include.

Don't recommend appending include to the path as makefile already does
this.

Instead of (partly) open coding watchdog_init_timeout to determine the
inital timeout use the core function that exists for exactly this
purpose.

As a side effect the "timeout-sec" device-tree property is recognized now
(though currently unused in the omap device trees).

Viresh Kumar a9a80e7e31 PM / OPP: Allow multiple OPP tables to be passed via DT
On some platforms (Like Qualcomm's SoCs), it is not decided until
runtime on what OPPs to use. The OPP tables can be fixed at compile
time, but which table to use is found out only after reading some efuses
(sort of an prom) and knowing characteristics of the SoC.

To support such platform we need to pass multiple OPP tables per device
and hardware should be able to choose one and only one table out of
those.

Update operating-points-v2 bindings to support that.

Viresh Kumar b901b51807 PM / OPP: Add new bindings to address shortcomings of existing bindings
Current OPP (Operating performance point) device tree bindings have been
insufficient due to the inflexible nature of the original bindings. Over
time, we have realized that Operating Performance Point definitions and
usage is varied depending on the SoC and a "single size (just frequency,
voltage) fits all" model which the original bindings attempted and
failed.

The proposed next generation of the bindings addresses by providing a
expandable binding for OPPs and introduces the following common
shortcomings seen with the original bindings:

- Getting clock/voltage/current rails sharing information between CPUs.
  Shared by all cores vs independent clock per core vs shared clock per
  cluster.

- Support for specifying current levels along with voltages.

- Support for multiple regulators.

- Support for turbo modes.

- Other per OPP settings: transition latencies, disabled status, etc.?

- Expandability of OPPs in future.

This patch introduces new bindings "operating-points-v2" to get these problems
solved. Refer to the bindings for more details.

We now have multiple versions of OPP binding and only one of them should
be used per device.

  - Lots of refactoring to avoid direct access to snd_soc_codec where
    it's not needed supporting future refactoring.
  - Big refactoring and cleanup serieses for the Wolfson ADSP and TI
    TAS2552 drivers.
  - Support for TI TAS571x power amplifiers.
  - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
  - Support for x86 systems with RT5650 and Qualcomm Storm.

Boris BREZILLON 1fa2e9ae1d crypto: mv_cesa - explicitly define kirkwood and dove compatible strings
We are about to add a new driver to support new features like using the
TDMA engine to offload the CPU.
Orion, Dove and Kirkwood platforms are already using the mv_cesa driver,
but Orion SoCs do not embed the TDMA engine, which means we will have to
differentiate them if we want to get TDMA support on Dove and Kirkwood.
In the other hand, the migration from the old driver to the new one is not
something all people are willing to do without first auditing the new
driver.
Hence we have to support the new compatible in the mv_cesa driver so that
new platforms with updated DTs can still attach their crypto engine device
to this driver.

Boris BREZILLON 51b44fc811 crypto: mv_cesa - use gen_pool to reserve the SRAM memory region
The mv_cesa driver currently expects the SRAM memory region to be passed
as a platform device resource.

This approach implies two drawbacks:
- the DT representation is wrong
- the only one that can access the SRAM is the crypto engine

The last point is particularly annoying in some cases: for example on
armada 370, a small region of the crypto SRAM is used to implement the
cpuidle, which means you would not be able to enable both cpuidle and the
CESA driver.

To address that problem, we explicitly define the SRAM device in the DT
and then reference the sram node from the crypto engine node.

Also note that the old way of retrieving the SRAM memory region is still
supported, or in other words, backward compatibility is preserved.

Vineet Gupta 8d0d56ba24 ARC: [axs101] support early 8250 uart
Earlycon calculates UART clock as "BASE_BAUD * 16". In case of ARC
"BASE_BAUD" is calculated dynamically in runtime, basically it is an
alias to arc_early_base_baud(), which in turn just does
"arc_base_baud/16".

8250 UART on AXS/SDP board uses 33.3MHz clock source which is set in
"arc_base_baud" with this change.

Additional compatibility string "snps,arc-sdp" is introduced as well
because there're different flavours of AXS boards but they all share the
same motherboard and so it's possible to re-use the same code for
motherbord even if CPU daughterboard changes.

Sam bobroff b4b56f9eca powerpc/tm: Abort syscalls in active transactions
This patch changes the syscall handler to doom (tabort) active
transactions when a syscall is made and return very early without
performing the syscall and keeping side effects to a minimum (no CPU
accounting or system call tracing is performed). Also included is a
new HWCAP2 bit, PPC_FEATURE2_HTM_NOSC, to indicate this
behaviour to userspace.

Currently, the system call instruction automatically suspends an
active transaction which causes side effects to persist when an active
transaction fails.

This does change the kernel's behaviour, but in a way that was
documented as unsupported.  It doesn't reduce functionality as
syscalls will still be performed after tsuspend; it just requires that
the transaction be explicitly suspended.  It also provides a
consistent interface and makes the behaviour of user code
substantially the same across powerpc and platforms that do not
support suspended transactions (e.g. x86 and s390).

Performance measurements using
http://ozlabs.org/~anton/junkcode/null_syscall.c indicate the cost of
a normal (non-aborted) system call increases by about 0.25%.

Mathias Krause 1a147ed75c ACPI: Constify ACPI device IDs in documentation
ACPI device ID arrays normally don't need to be written to as they're
only ever read. The common usage -- embedding pointers to acpi_device_id
arrays in other data structures -- reference them as 'const', e.g. as in
struct acpi_driver / acpi_scan_handler / device_driver. The matchers are
taking const pointers, too. So it's only natural, to propose using const
arrays. Change the documentation accordingly.

Mike Snitzer bccab6a01a dm cache: switch the "default" cache replacement policy from mq to smq
The Stochastic multiqueue (SMQ) policy (vs MQ) offers the promise of
less memory utilization, improved performance and increased adaptability
in the face of changing workloads.  SMQ also does not have any
cumbersome tuning knobs.

Users may switch from "mq" to "smq" simply by appropriately reloading a
DM table that is using the cache target.  Doing so will cause all of the
mq policy's hints to be dropped.  Also, performance of the cache may
degrade slightly until smq recalculates the origin device's hotspots
that should be cached.

In the future the "mq" policy will just silently make use of "smq" and
the mq code will be removed.

The rk3368 is the first ARM64 soc from Rockchip, but seems to share most
peripherals with the ARM32 soc, including the pinctrl functionality.
The only notable difference is - as with every Rockchip soc - that the
offsets in the General Register Files moved around and a split of the pmu
section of the rk3288 into pmu and pmugrf (pmu general register files)
sections. The pinctrl driver of course only needs the pmugrf registers
for controlling the pin settings.

Allow users of remoteproc the ability to get a handle to an rproc by
passing a phandle supplied in the user's device tree node. This is
useful in situations that require manual booting of the rproc.

This patch uses the code removed by commit 40e575b1d0 ("remoteproc:
remove the get_by_name/put API") for the ref counting but is modified
to use a simple list and locking mechanism and has rproc_get_by_name
replaced with an rproc_get_by_phandle API.

Mimi Zohar 24fd03c876 ima: update builtin policies
This patch defines a builtin measurement policy "tcb", similar to the
existing "ima_tcb", but with additional rules to also measure files
based on the effective uid and to measure files opened with the "read"
mode bit set (eg. read, read-write).

Changing the builtin "ima_tcb" policy could potentially break existing
users.  Instead of defining a new separate boot command line option each
time the builtin measurement policy is modified, this patch defines a
single generic boot command line option "ima_policy=" to specify the
builtin policy and deprecates the use of the builtin ima_tcb policy.

[The "ima_policy=" boot command line option is based on Roberto Sassu's
"ima: added new policy type exec" patch.]

Cyrille Pitchen 2c01a3d6b3 spi: atmel: update DT bindings documentation
- add new property "atmel,fifo-size"
- change "cs-gpios" to optional for SPI controller version >= 2.

Please be aware that the VERSION register can not be used to guess the
size of FIFOs. Indeed, for a given hardware version, the SPI controller
can be integrated on Atmel SoCs with different FIFO sizes. Also the
"atmel,fifo-size" property is optional as older SPI controllers don't
embed FIFO at all.

Besides, the FIFO size can not be read or guessed from other registers:
When designing the FIFO feature, no dedicated registers were added to
store this size. Unused spaces in the I/O register range are limited and
better reserved for future usages. Instead, the FIFO size of each
peripheral is documented in the programmer datasheet.

Finally, on a given SoC, there can be several instances of the SPI
controller with different FIFO sizes. This explain why we'd rather use a
dedicated DT property than use the "compatible" property.

For instance, sama5d2x SoCs come with some SPI controllers, the ones
inside Flexcoms, integrating 32 data FIFOs whereas other SPI controllers
use 16 data FIFOs. All these SPI controllers share the same IP version.

Scott Feldman b4ad7baa01 bridge: del external_learned fdbs from device on flush or ageout
We need to delete from offload the device externally learnded fdbs when any
one of these events happen:

1) Bridge ages out fdb.  (When bridge is doing ageing vs. device doing
ageing.  If device is doing ageing, it would send SWITCHDEV_FDB_DEL
directly).

2) STP state change flushes fdbs on port.

3) User uses sysfs interface to flush fdbs from bridge or bridge port:

	echo 1 >/sys/class/net/BR_DEV/bridge/flush
	echo 1 >/sys/class/net/BR_PORT/brport/flush

4) Offload driver send event SWITCHDEV_FDB_DEL to delete fdb entry.

For rocker, we can now get called to delete fdb entry in wait and nowait
contexts, so set NOWAIT flag when deleting fdb entry.

Alexandru M Stan f44c21ff6d mfd: cros_ec: spi: Add a DT property to delay asserting the CS
Some ECs need a little time for waking up before they can accept
SPI data at a high speed. Add a "google,cros-ec-spi-pre-delay"
property to the DT binding to configure this.

If this property isn't set, then no delay will be added. However,
if set it will cause a delay equal to the value passed to it to
be inserted at the beginning of a transaction.

Linus Torvalds c39f3bc659 Merge git://git.infradead.org/intel-iommu
Pull VT-d hardware workarounds from David Woodhouse:
 "This contains a workaround for hardware issues which I *thought* were
  never going to be seen on production hardware.  I'm glad I checked
  that before the 4.1 release...

  Firstly, PASID support is so broken on existing chips that we're just
  going to declare the old capability bit 28 as 'reserved' and change
  the VT-d spec to move PASID support to another bit.  So any existing
  hardware doesn't support SVM; it only sets that (now) meaningless bit
  28.

  That patch *wasn't* imperative for 4.1 because we don't have PASID
  support yet.  But *even* the extended context tables are broken — if
  you just enable the wider tables and use none of the new bits in them,
  which is precisely what 4.1 does, you find that translations don't
  work.  It's this problem which I thought was caught in time to be
  fixed before production, but wasn't.

  To avoid triggering this issue, we now *only* enable the extended
  context tables on hardware which also advertises "we have PASID
  support and we actually tested it this time" with the new PASID
  feature bit.

  In addition, I've added an 'intel_iommu=ecs_off' command line
  parameter to allow us to disable it manually if we need to"

David Woodhouse c83b2f20fd iommu/vt-d: Only enable extended context tables if PASID is supported
Although the extended tables are theoretically a completely orthogonal
feature to PASID and anything else that *uses* the newly-available bits,
some of the early hardware has problems even when all we do is enable
them and use only the same bits that were in the old context tables.

For now, there's no motivation to support extended tables unless we're
going to use PASID support to do SVM. So just don't use them unless
PASID support is advertised too. Also add a command-line bailout just in
case later chips also have issues.

The equivalent problem for PASID support has already been fixed with the
upcoming VT-d spec update and commit bd00c606a ("iommu/vt-d: Change
PASID support to bit 40 of Extended Capability Register"), because the
problematic platforms use the old definition of the PASID-capable bit,
which is now marked as reserved and meaningless.

So with this change, we'll magically start using ECS again only when we
see the new hardware advertising "hey, we have PASID support and we
actually tested it this time" on bit 40.

The VT-d hardware architect has promised that we are not going to have
any reason to support ECS *without* PASID any time soon, and he'll make
sure he checks with us before changing that.

In the future, if hypothetical new features also use new bits in the
context tables and can be seen on implementations *without* PASID support,
we might need to add their feature bits to the ecs_enabled() macro.

Samuel Thibault f60c8ba77d Input: export LEDs as class devices in sysfs
This change creates a new input handler called "leds" that exports LEDs on input
devices as standard LED class devices in sysfs and allows controlling their
state via sysfs or via any of the standard LED triggers. This allows to
re-purpose and reassign LDEs on the keyboards to represent states other
than the standard keyboard states (CapsLock, NumLock, etc).

The old API of controlling input LEDs by writing into /dev/input/eventX
devices is still present and will take precedence over accessing via LEDs
subsystem (i.e. it may override state set by a trigger). If input device is
"grabbed" then requests coming through LED subsystem will be ignored.

Joe Thornber 028ae9f76f dm cache: add fail io mode and needs_check flag
If a cache metadata operation fails (e.g. transaction commit) the
cache's metadata device will abort the current transaction, set a new
needs_check flag, and the cache will transition to "read-only" mode.  If
aborting the transaction or setting the needs_check flag fails the cache
will transition to "fail-io" mode.

Once needs_check is set the cache device will not be allowed to
activate.  Activation requires write access to metadata.  Future work is
needed to add proper support for running the cache in read-only mode.

Once in fail-io mode the cache will report a status of "Fail".

Also, add commit() wrapper that will disallow commits if in read_only or
fail mode.

There are different types of PHY from one chipset to another, while
the DSI host controller is relatively consistent across platforms.
Also, the PLL inside PHY is providing the source of DSI byte and
pixel clocks, which are used by DSI host controller. Separated devices
for clock provider and clock consumer make DSI driver better fit into
common clock framework.

Sergei Shtylyov c156633f13 Renesas Ethernet AVB driver proper
Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically
compatible with SuperH Gigabit Ethernet E-MAC.  Ethernet AVB has  a  dedicated
direct memory access controller (AVB-DMAC) that is a new design compared to the
SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE
802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real-
time transfer, and the IEEE 802.1Qat stream reservation protocol.

The  driver only supports device tree probing, so the binding document is
included in this patch.

Based on the original patches by Mitsuhiro Kimura.

Alexey Kardashevskiy e633bc86a9 vfio: powerpc/spapr: Support Dynamic DMA windows
This adds create/remove window ioctls to create and remove DMA windows.
sPAPR defines a Dynamic DMA windows capability which allows
para-virtualized guests to create additional DMA windows on a PCI bus.
The existing linux kernels use this new window to map the entire guest
memory and switch to the direct DMA operations saving time on map/unmap
requests which would normally happen in a big amounts.

This adds 2 ioctl handlers - VFIO_IOMMU_SPAPR_TCE_CREATE and
VFIO_IOMMU_SPAPR_TCE_REMOVE - to create and remove windows.
Up to 2 windows are supported now by the hardware and by this driver.

This changes VFIO_IOMMU_SPAPR_TCE_GET_INFO handler to return additional
information such as a number of supported windows and maximum number
levels of TCE tables.

DDW is added as a capability, not as a SPAPR TCE IOMMU v2 unique feature
as we still want to support v2 on platforms which cannot do DDW for
the sake of TCE acceleration in KVM (coming soon).

Alexey Kardashevskiy 2157e7b82f vfio: powerpc/spapr: Register memory and define IOMMU v2
The existing implementation accounts the whole DMA window in
the locked_vm counter. This is going to be worse with multiple
containers and huge DMA windows. Also, real-time accounting would requite
additional tracking of accounted pages due to the page size difference -
IOMMU uses 4K pages and system uses 4K or 64K pages.

Another issue is that actual pages pinning/unpinning happens on every
DMA map/unmap request. This does not affect the performance much now as
we spend way too much time now on switching context between
guest/userspace/host but this will start to matter when we add in-kernel
DMA map/unmap acceleration.

This introduces a new IOMMU type for SPAPR - VFIO_SPAPR_TCE_v2_IOMMU.
New IOMMU deprecates VFIO_IOMMU_ENABLE/VFIO_IOMMU_DISABLE and introduces
2 new ioctls to register/unregister DMA memory -
VFIO_IOMMU_SPAPR_REGISTER_MEMORY and VFIO_IOMMU_SPAPR_UNREGISTER_MEMORY -
which receive user space address and size of a memory region which
needs to be pinned/unpinned and counted in locked_vm.
New IOMMU splits physical pages pinning and TCE table update
into 2 different operations. It requires:
1) guest pages to be registered first
2) consequent map/unmap requests to work only with pre-registered memory.
For the default single window case this means that the entire guest
(instead of 2GB) needs to be pinned before using VFIO.
When a huge DMA window is added, no additional pinning will be
required, otherwise it would be guest RAM + 2GB.

The new memory registration ioctls are not supported by
VFIO_SPAPR_TCE_IOMMU. Dynamic DMA window and in-kernel acceleration
will require memory to be preregistered in order to work.

The accounting is done per the user process.

This advertises v2 SPAPR TCE IOMMU and restricts what the userspace
can do with v1 or v2 IOMMUs.

In order to support memory pre-registration, we need a way to track
the use of every registered memory region and only allow unregistration
if a region is not in use anymore. So we need a way to tell from what
region the just cleared TCE was from.

This adds a userspace view of the TCE table into iommu_table struct.
It contains userspace address, one per TCE entry. The table is only
allocated when the ownership over an IOMMU group is taken which means
it is only used from outside of the powernv code (such as VFIO).

As v2 IOMMU supports IODA2 and pre-IODA2 IOMMUs (which do not support
DDW API), this creates a default DMA window for IODA2 for consistency.

Greg Kroah-Hartman 78a66b00d9 Third round of new IIO drivers, cleanups and functionality for the 4.2 cycle.
Given Linus announced a 4.8rc coming up, hopefully time for one more
 lot of IIO patches this cycle.  Some of these are actually
 improvements / fixes for patches earlier in the cycle.
 
 New device support
 * st_accel driver - support devices with 8 bit channels.
 
 Cleanup
 * A general cleanup of the iio tools under /tools/ from Hartmut.
   I'm more than a little embarassed by how bad some of these were! Are well,
   much more refined and less bug prone now.
   These cover lots of stuff like unhandled error returns, memory leaks as
   well as general refactoring to tidy the code up.
 * iio_simple_dummy - fix memory leaks in the init functions, drop some
   pointless error returns from functions that never generate errors and
   make the module parameter explicitly unsigned.
 * More buffer handling reworks from Lars-Peter, this time targetting hardware
   buffers (a little used corner that looks likely to get more use in the near
   future). Specifically:
   - Always compute the masklength as inkernel buffer users may need it.
   - Add a means of labeling which buffer modes a given buffer implementation
     supports.
   - In the case of hardware buffers, require strict scan matching rather than
     matching to a superset.  Currently the demux is bypassed by these drivers
     (this may well not change for efficiency reasons) so allowing a superset
     of channels to be selected would otherwise lead to more data than requested
     confusing userspace.
 
 Driver funcationality improvments
 * mmc35240 - adds a compensation to the raw values as borrowed form Memsic's
   own input driver.
 * mma8452
   - event support
   - event debouncing
   - high  pass filter configuration
   - triggers
 * vf610 - allow conversion mode to be adjusted
 
 Fixlets
 * mmc35240
   - Off by one error that by coincidence had no real effect.
   - i2c_device_name should be lowercase.
   - Lack of null terminator at end of attributes array.
   - Avoid computing the fractional part of the magnetic field by moving
     the scaling into userspace where floating point is available to simplify
     the maths.
   - Use a smaller sleep before assuming the measurement is done.  This is
     safe and improves the possible polling rate.
   - Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd
     code and the value used in the code seems to be correct.
 * stk3310 - make a local variable signed to ensure error handling works.
 * twl4030
   - fix calculation of the temperature sense current - bug unlikely
     to have ever been noticed as the difference is small.
   - Fix errors in descriptions.

The Marvell Armada 38x SoC introduce new features to the XOR engine,
especially the fact that the engine mode (MEMCPY/XOR/PQ/etc) can be part of
the descriptor and not set through the controller registers.

This new feature allows mixing of different commands (even PQ) on the same
channel/chain without the need to stop the engine to reconfigure the engine
mode.

Refactor the driver to be able to use that new feature on the Armada 38x,
while keeping the old behaviour on the older SoCs.

After updating to the latest Armada XP datasheet, we discovered that
there is a second SPI bus accessible from the MPP pins, called 'spi1'.

In order to be consistent with other SoCs having two SPI busses, this
commit renames the functions of the first SPI bus to 'spi0' instead of
just 'spi'.

This commit obviously breaks the DT backward compatibility for the
people using the "spi" function name in their Device Tree.

This commit normalizes the naming of the Ethernet txclkout pin to be

binding documentation of the Armada XP was wrong for MPP12: it said
the function was ge1(txd0), while it is in fact ge1(txclkout). It is
however not really a fix worth sending to stable since it does not
change the behavior, and the driver itself was correct.

This commit normalizes the naming of the TDM pins accross the

 * Removing the 'n' from signal names: 'intn' becomes 'int' and 'rstn'
   becomes 'rst'

 * Renaming the main name 'tdm2c' to 'tdm' on Armada 38x.

 * Change the main name 'tdm-1' to 'tdm' for one of the pins of the

The last two changes affect DT compatibility, but since the TDM
interface is nowhere near being supported in mainline, it should not
be considered to be a serious problem at this point.

Thomas Petazzoni 5cc0de1faf pinctrl: mvebu: armada-39x: align NAND pin naming
All SoCs use "nand" to designate NAND pins, only Armada 39x is using
"nd", which is not consistent. This commit fixes that by renaming the
corresponding functions.

It also changes the subnames from rbn0/rbn1 to rb0/rb1, to respect the
convention used everywhere that we don't encode the 'n' part of signal
names.

While this commit changes the main name of function, therefore

Thomas Petazzoni 7bd6a26db6 pinctrl: mvebu: armada-{370,375,38x,39x}: normalize dev pins
This commit modifies the definition of the Device Bus interface pins
to be consistent accross SoCs. Especially, it removes the 'n'
indicators that we don't encode in the subnames of pins:

   'dev(wen0)' becomes 'dev(we0)'
   'dev(wen1)' becomes 'dev(we1)'
   'dev(oen)' becomes 'dev(oe)'
   etc.

In addition, it fixes the Armada 375 DT binding documentation, which
forgot to document the 'dev' function for MPP46, MPP57 and MPP63.

Since only the subnames are changed, this commit does not affect DT
compatibility.

Thomas Petazzoni ddf3f19e21 pinctrl: mvebu: armada-39x: normalize SDIO pin naming
In order to be consistent with the datasheet and some other SoCs, this
commit renames the SDIO pins of the Armada 39x from "sd" to "sd0".

While this changes the DT binding, this is not a problem since Armada
39x is a brand new SoC which isn't used in production yet (so now is
the right time to fix such things).

Thomas Petazzoni 52f83174b3 pinctrl: mvebu: armada-39x: normalize SATA present functionality naming
This commit makes the naming of SATA related MPP functions consistent
accross SoCs by adjusting the Armada 39x definition to use "prsnt"
instead of "present".

Since only the subnames are changed, the DT binding is not modified at
all.

Thomas Petazzoni 100dc5d840 pinctrl: mvebu: armada-{38x,39x,xp}: normalize naming of DRAM functions
This commit makes the dram functions naming (both the name and
subname) consistent accross SoC, by using:

  dram(vttctrl)
  dram(deccerr)

in all Marvell SoCs.

Due to the change to the name, it changes the DT binding, but these
functions are not used by any in-tree Device Tree file, and are very
unlikely to be used by anyone.

The subnames are purely informative, but it's nicer when they match
accross SoCs. This commit adjusts the Armada 375, Armada 38x and
Armada 39x MPP definitions so that the subnames of the PTP pins match
the ones used on Armada XP and Kirkwood.

A new revision of the Marvell Armada 38x hardware datasheet unveiled
that the definition of some of the PCIe functions were not
correct. This commit fixes the pinctrl driver accordingly.

Some PCIe functions simply do not exist, some of the PCIe functions in
fact were corresponding to other functions, and some PCIe functions
have been added.

Note: the seemingly unrelated removal of spi(cs2) on MPP47 is related:
this function is in fact implemented on MPP43, instead of a PCIe
function.
