5740682e66 drm/amdgpu:implement new GPU recover(v3)
1,new imple names amdgpu_gpu_recover which gives more hint
on what it does compared with gpu_reset

2,gpu_recover unify bare-metal and SR-IOV, only the asic reset
part is implemented differently

3,gpu_recover will increase hang job karma and mark its entity/context
as guilty if exceeds limit

V2:

4,in scheduler main routine the job from guilty context  will be immedialy
fake signaled after it poped from queue and its fence be set with
"-ECANCELED" error

5,in scheduler recovery routine all jobs from the guilty entity would be
dropped

6,in run_job() routine the real IB submission would be skipped if @skip parameter
equales true or there was VRAM lost occured.

V3:

7,replace deprecated gpu reset, use new gpu recover

48f05f2955 amd/scheduler:imple job skip feature(v3)
jobs are skipped under two cases
1)when the entity behind this job marked guilty, the job
poped from this entity's queue will be dropped in sched_main loop.

2)in job_recovery(), skip the scheduling job if its karma detected
above limit, and also skipped as well for other jobs sharing the
same fence context. this approach is becuase job_recovery() cannot
access job->entity due to entity may already dead.

v2:
some logic fix

v3:
when entity detected guilty, don't drop the job in the poping
stage, instead set its fence error as -ECANCELED

in run_job(), skip the scheduling either:1) fence->error < 0
or 2) there was a VRAM LOST occurred on this job.
this way we can unify the job skipping logic.

with this feature we can introduce new gpu recover feature.

4952d4c584 drm/amd/display: DMCU FW loading from PSP
Update the programming sequence to allow DMCU firmware to be loaded by
PSP. This code detects whether the firmware is loaded and does a check
to verify the expected interface version and checks for correct response
from micro controller.

Added registry key method to allow force loading of firmware from kernel
mode driver for test purposes. This is old method of firmware loading
without PSP.

Moved some init sequences into dc/dmcu.

Changed loading sequence to initialize IRAM after firmware completely
loaded. Firmware will now disable features that use IRAM
until initialized.

consume the items in the fifo while holding reservation lock
on a BO. The gpu reset thread on the other hand blocks the scheduler
during reset. Before it unblocks the sceduler it might want
to recover VRAM and so will try to reserve the same BO the producer
thread is already holding creating a deadlock.

Fix:
Switch from kfifo to SPSC queue which is unlimited in size.

401712e035 drm: rcar-du: Clip planes to screen boundaries
Unlike the KMS API, the hardware doesn't support planes exceeding the
screen boundaries or planes being located fully off-screen. We need to
clip plane coordinates to support the use case.

Fortunately the DRM core offers a drm_atomic_helper_check_plane_state()
helper that validates the scaling factor and clips the plane
coordinates. Use it to implement the plane atomic check and use the
clipped source and destination rectangles from the plane state instead
of the unclipped source and CRTC coordinates to configure the device.

ca0e68e21a drm/prime: skip CPU sync in map/unmap dma_buf
Dma-bufs should already be device coherent, as they are only pulled in the
CPU domain via the begin/end cpu_access calls. As we cache the mapping set
up by dma_map_sg a CPU sync at this point will not actually guarantee proper
coherency on non-coherent architectures, so we can as well stop pretending.

This is an important performance fix for architectures which need explicit
cache synchronization and userspace doing lots of dma-buf imports.
Improves Weston on Etnaviv performance 5x, where before this patch > 90%
of Weston CPU time was spent synchronizing caches for buffers which are
already device coherent.

e2f930aaa3 drm: rcar-du: Don't set connector DPMS property
Since commit 4a97a3da42 ("drm: Don't update property values for atomic
drivers") atomic drivers must not update property values as properties
are read from the state instead. To catch remaining users, the
drm_object_property_set_value() function now throws a warning when
called by atomic drivers on non-immutable properties, and we hit that
warning when creating connectors.

The easy fix is to just remove the drm_object_property_set_value() as it
is used here to set the initial value of the connector's DPMS property
to OFF. The DPMS property applies on top of the connector's state crtc
pointer (initialized to NULL) that is the main connector on/off control,
and should thus default to ON.

The available documentation fails to mention this fact. I
contacted some hardware people who eventually managed to locate
the relevant HSD for VLV, which was resolved by declaring
interlaced DP output as not supported. The HSD was never cloned
for CHV even though it inherited most of the hardware and
thus has the same problems with interlaced DP output.

8fedd64dab drm/i915: Fix vblank timestamp/frame counter jumps on gen2
Previously I was under the impression that the scanline counter
reads 0 when the pipe is off. Turns out that's not correct, and
instead the scanline counter simply stops when the pipe stops, and
it retains it's last value until the pipe starts up again, at which
point the scanline counter jumps to vblank start.

These jumps can cause the timestamp to jump backwards by one frame.
Since we use the timestamps to guesstimage also the frame counter
value on gen2, that would cause the frame counter to also jump
backwards, which leads to a massice difference from the previous value.
The end result is that flips/vblank events don't appear to complete as
they're stuck waiting for the frame counter to catch up to that massive
difference.

Fix the problem properly by actually making sure the scanline counter
has started to move before we assume that it's safe to enable vblank
processing.

v2: Less pointless duplication in the code (Chris)

5816d9cbc0 drm/i915: Fix deadlock in i830_disable_pipe()
i830_disable_pipe() gets called from the power well code, and thus
we're already holding the power domain mutex. That means we can't
call plane->get_hw_state() as it will also try to grab the
same mutex and will thus deadlock.

Replace the assert_plane() calls (which calls ->get_hw_state()) with
just raw register reads in i830_disable_pipe(). As a bonus we can
now get a warning if plane C is enabled even though we don't even
expose it as a drm plane.

v2: Do a separate WARN_ON() for each plane (Chris)

b5e0a9418e drm/i915: Set fake_vma.size as well as fake_vma.node.size for capture
When capturing the bo, we allocate an error object with an array of
min(vma->size, vma->node.size) pages, plus a bit for compression overhead.
However, when creating the fake vma to describe the bo, only one of the
sizes was filled in, resulting in a too small array. Through my and CI
testing, this was sufficient for the mostly empty NULL context as
it compressed well (or the out-of-bounds access simply didn't cause an
issue). However, in real workloads on Cannonlake, we were overflowing
that array and causing havoc with the random memory corruption.

- Put the conditions for enabling and disabling IPS in a helper.
Changes since v3:
- Keep the max_cdclk workaround working. (Ville)
- Also check logical cdclk out of paranoia.
- Remove planes check from IPS disable function for initial disable.
- Remove assert_plane_enabled/disabled checks and use
  crtc_state->active_planes for hsw_enable_ips only, always allow
  calling hsw_disable_ips to disable it initially in hw.

ff71c2cf5e drm/sun4i: use sun4i_tcon_of_table to check if a device node is a TCON
The sun4i DRM driver maintains a list of compatible strings it uses to
check if a device node within the display component graph is a TCON.
The TCON driver also has this list, used to bind the TCON driver to
the device. These two lists are identical.

Instead of maintaining two identical lists, export the list from the
TCON driver for the DRM driver to use.

a152992062 drm/imx: always call wait_for_flip_done in commit_tail
drm_atomic_helper_wait_for_vblanks will go away in the future.

The new drm_atomic_helper_setup_commit in 4.15 expects that blocking commits
have completed flipping before the commit_tail returns. This must be ensured
by calling wait_for_vblanks or wait_for_flip_done, where flip_done might do
a less agressive wait, which is fine for imx-drm.

5643205c63 drm/i915: Avoid PPS HW/SW state mismatch due to rounding
We store a SW state of the t11_t12 timing in 100usec units but have to
program it in 100msec as required by HW. The rounding used during
programming means there will be a mismatch between the SW and HW states
of this value triggering a "PPS state mismatch" error. Avoid this by
storing the already rounded-up value in the SW state.

Note that we still calculate panel_power_cycle_delay with the finer
100usec granularity to avoid any needless waits using that version of
the delay.

Commit d178e034d5 ("drm: omapdrm: Move FEAT_DPI_USES_VDDS_DSI feature
to dpi code") replaced usage of platform data version with SoC matching
to configure DPI VDDS. The SoC match entries were incorrect, they should
have matched on the machine name instead of the SoC family. Fix it.

The result was observed on OpenPandora with OMAP3530 where the panel only
had the Blue channel and Red&Green were missing. It was not observed on
GTA04 with DM3730.

23970e150a omapdrm: hdmi4: Correct the SoC revision matching
I believe the intention of the commit 2c9fc9bf45
("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver")
was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions,
like omap4460.

By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a
same way as it would treat omap4430 ES1.x

This breaks HDMI audio on OMAP4460 devices (PandaES for example).

Correct the match rule so we are not going to get false positive match.

1b6fba458c drm/bridge: adv7511/33: Fix adv7511_cec_init() failure handling
If the device tree for a board did not specify a cec clock, then
adv7511_cec_init would return an error, which would cause adv7511_probe()
to fail and thus there is no HDMI output.

There is no need to have adv7511_probe() fail if the CEC initialization
fails, so just change adv7511_cec_init() to a void function. In addition,
adv7511_cec_init() should just return silently if the cec clock isn't
found and show a message for any other errors.

An otherwise correct cleanup patch from Dan Carpenter turned this broken
failure handling into a kernel Oops, so bisection points to commit
7af35b0add ("drm/kirin: Checking for IS_ERR() instead of NULL") rather
than 3b1b975003 ("drm: adv7511/33: add HDMI CEC support").

while using GuC action UK_LOG_ENABLE_LOGGING.
However i915 is currently not doing this because it is version
specific change and can be handled entirely in GuC. It will need
to be fixed in future firmwares.

This update includes (since v9.14):

- DCC spec changes for BXT + DCT enabling
- Bug Fix for power conservation feature SLPC_DCC
- Scheduler 1-element submission during DCC cycles.
- SB based Pre-ETM/ETM flow enabling for debug signed GuC/HuC
- Moving GuC non_critical r/w data to lower SRAM 64KB
- Media engine Reset fix.  Correctly marking context for resubmission in
  Media Reset case.
- ABT Disable bug fix. Disabled Evaluation mode on context change.
- Async FW in Engine Schedule feature (not enabled from KMD)
- GuC clean up to align developer build in line to production build.
- Disable ARAT interrupt before programming ARAT delta.
- Memory range check in Parse to avoid failure due to overflow.
- GuC Msg Channel Hang WA - Stall GUC for mmio access when IDI is low
  during CPD flow.
- Fix for submit queue over flow issue
- Enabling IBC on KBL GT3 15W, GT4 45W
- Disabling wrong device ID WA in production signed kernel
- Enabling WA for MSGCH hang issue upto required KBL stepping
- Clear forcewake in CSB when SQ is empty.
- 3Tries of GuC2CSME wake request
- During reset one parameter was not getting accounted
- Disable DCC 1-elem mode submission
- Move UkGuckmdInterface.h file from 2016 folders to common 2016 folder.
- This is file location change.No functional change done as part of this
  check in.

- Enabling Dynamic Render Power Well Hysteresis Programming for Compute
  Worklaods
- Enabling build failure check to catch critical section overflow.
- Disable build.bat redundant prints.
- Move few least used functions to non-critical section.
- Rearrange GuC documentation folder structure.

580b9d05a3 drm/i915/guc: Change default GuC FW for SKL to v9.33
This patch makes v9.33 firmware as default firmware for SKL.

Note: GuC logging control is changed with this firmware. GuC is
expecting i915 to set control bit to enable "default logging"
while using GuC action UK_LOG_ENABLE_LOGGING.
However i915 is currently not doing this because it is version
specific change and can be handled entirely in GuC. It will need
to be fixed in future firmwares.

This update includes (since v6.1):

- HuC RSA Keys updated.
- Adding per engine preemption support in GuC scheduler
- Minor bug fixes.
- Added support to log media reset count for host to read it
- Sub-feature level control for power management features.
- Minor clean-up for power management interface.
- Unified power management interface and scheduler interface into
  1 file using same version.
- Bug Fix for multi context scheduler flag.
- DCC spec changes for BXT + DCT enabling
- SB based Pre-ETM/ETM flow enabling for debug signed GuC/HuC
- Moving GuC non_critical r/w data to lower SRAM 64KB
- Media engine Reset fix.  Correctly marking context for resubmission in
  Media Reset case.
- ABT Disable bug fix. Disabled Evaluation mode on context change.
- Async FW in Engine Schedule feature (not enabled from KMD)
- GuC clean up to align developer build in line to production build.
- DCC consistency fix for SKL
- Disable ARAT interrupt before programming ARAT delta.
- Memory range check in Parse to avoid failure due to overflow.
- Enabled WA for MSGCH hang issue
- Clear forcewake in CSB when SQ is empty.
- Move UkGuckmdInterface.h file from 2016 folders to common 2016 folder.
- This is file location change.No functional change done as part of this
  check in.
- Enable decoupled freq for SKL GT4
- 3 tries of wake request needed from GuC2CSME for ME to wake up. Request
  has come from ME spec
- During reset one parameter was not getting accounted
- Enabling Guc Log changes for ultra low logging for OCA
- Enabling build failure check to catch critical section overflow.
- Disable build.bat redundant prints.
- Move few least used functions to non-critical section.
- Rearrange GuC documentation folder structure.
- Synchronize SLPC internal debug interface with other branches.
- Fixing Issue with Default Guc Log changes for OCA using special Control
  Bit

v2: Rebase. Updated commit message.

7fdf165a52 drm/radeon: remove init of CIK VMIDs 8-16 for amdkfd
VMIDs 8-16 in Kaveri were reserved for use by the amdkfd driver.
Because we removed amdkfd support from radeon, those VMIDs are now
used by radeon and are initialized by radeon.

This patch removes the function that initialized those VMIDs for amdkfd
use.
This initialization overridden the radeon initialization and caused GPU
faults and GUI crashed.

52dd06506e drm/fb_helper: Disable all crtc's when initial setup fails.
Some drivers like i915 start with crtc's enabled, but with deferred
fbcon setup they were no longer disabled as part of fbdev setup.
Headless units could no longer enter pc3 state because the crtc was
still enabled.

Fix this by calling restore_fbdev_mode when we would have called
it otherwise once during initial fbdev setup.

a76dfe350c drm/atomic: make drm_atomic_helper_wait_for_vblanks more agressive
drm_atomic_helper_setup_commit expects that flipping of previous commits
has happened when it is called to set up a new commit. This can be violated
by commits where userspace doesn't get a flip completion event to
synchronize against i.e. legacy modesets and property changes.

The expectation is that those are done by blocking commits, which wait for
completion. Most drivers call drm_atomic_helper_wait_for_vblanks in the
commit_tail to ensure completion, but the wait for next vblank might not
actually happen if the commit didn't change any planes.

Make the wait more agressive by also waiting if no planes changed. This
is the minimal regression fix for the 4.15 kernel series. Long term
drivers should switch away from drm_atomic_helper_wait_for_vblanks and
use drm_atomic_helper_wait_for_flip_done instead.

cf669b4e9f drm/i915: Consolidate checks for engine stats availability
Sagar noticed the check can be consolidated between the engine stats
implementation and the PMU.

My first choice was a static inline helper but that got into include
ordering mess quickly fast so I went with a macro instead. At some point
we should perhaps looking into taking out the non-ringubffer bits from
intel_ringbuffer.h into a new intel_engine.h or something.

v2: Use engine->flags. (Chris Wilson)
v3: Rebase and mark GuC as not yet supported. (Chris Wilson)
v4: Move flag setting to intel_engines_reset_default_submission.
    (Chris Wilson)
v5: Move flag setting to logical_ring_setup.
v6: intel_engines_reset_default_submission is the wrong place to set the

8ffca5dca0 drm/amd/display: Do DC mode-change check when adding CRTCs
Within atomic check, dm_update_crtcs_state is called twice. First to
remove from the dc_state, and subsequently to add to it.

In both calls, a secondary mode-change check is done using dc-level
states. We shouldn't be doing this while removing, since a new
dc_stream_state has not been created to do the necessary comparison.
Because of this, the mode_changed flag within the DRM state can be
mistakenly set to false. Doing so only when adding prevents this.

We are also guaranteed that a call to add will come after remove, or
else the atomic check fails (and a commit will not happen).

6bffebc90c drm/amd/display: Add timing validation against dongle cap
For DP active dongles, the dpcd dongle caps are read but not
used to validate mode timing. This addresses this.

In particular, this change fixes light up on the HDMI 4k TV
connected through DP active dongle. Since the 4k TV defaults
to YCbCr420, which the dongle don't support.

This change does not address MST cases, a more generalized
approach must be taken for that.

00a797225e drm/i915/pmu: Return -EINVAL when selecting the inactive CPU
In commit 0426c04654 ("drm/i915/pmu: Only allow running on a single
CPU") I attempted to clarify the CPU hotplug logic in our PMU
implementation, but missed that a more logical error to return, when
attempting to initialize an event on a currently inactive CPU, is -EINVAL
rather than -ENODEV.

This is because i915 PMU explicitly disallows running counters on more
than one CPU at a time, and is not reporting that the requested CPU does
not exist, or is off-line.

448aa9117c drm/i915: Enable hotplug polling after registering the outputs
Previously we would enable hotplug polling on the outputs immediately
upon construction. This would allow a very early hotplug event to
trigger before we had finishing setting up the driver to handle it.
Instead, move the output polling to the last step of registration, after
we have set up all handlers, including the fbdev configuration.

v2: Symmetrically turnoff the hotplug helper in unregister after the
fbdev is first synchronised then finalized. This stops a late hotplug
event being processed after the interrupts are disabled.

Previously the performance is improved through the workload auditing
and shadowing ahead of vGPU scheduling, however, there is the case that
more requests are allocated in submit_context before the previous request
is added, the timeline will hold its seqno which is later.

This patch is to move the request alloc to dispatch_workload function,
where is the same place as request is added.

It will fix the issue of kernel BUG for (timeline->seqno != request->fence.seqno)
check when add_request.

bf3a26b3cb drm/i915/gvt: remove skl_misc_ctl_write handler
With different settings of compressed data hash mode between VMs and host

Commit: 1999f108c ("drm/i915/gvt: Disable compression workaround for Gen9")
disable compression workaround of guest in gvt host to align with host.

Commit: 93564044f ("drm/i915: Switch over to the LLC/eLLC hotspot avoidance

skl_misc_ctl_write hanlder.

Better solution should be always keeping same settings as host, and bypass
the write request from VMs, but it need to fetch data from host's
"Context".

In order to keep the dev_priv->ifbdev alive after failure, we have to
avoid the free and leave it empty until we unload the module (which is
less than ideal, but a necessary evil for simplicity). Then we can use
intel_fbdev_sync() to serialise the hotplug event with the configuration.
The serialisation between the two was removed in commit 934458c2c9
("Revert "drm/i915: Fix races on fbdev""), but the use after free is much
older, commit 366e39b4d2 ("drm/i915: Tear down fbdev if initialization
fails")

Even though all rendering should have been flushed at the end of the

kernel_context. As the switch to the kernel_context is used when idling
the gpu (e.g. suspend), having an extra layer of paranoia to ensure
everything is flushed to memory seems sensible.

44a2d56429 drm/via: use monotonic time for VIA_WAIT_IRQ
The normal DRM vblank interrupt events started using monotonic times in
commit c61eef726a ("drm: add support for monotonic vblank timestamps"),
which is useful for a number of reasons, including the possible y2038
overflow.

The VIA_WAIT_IRQ ioctl uses the same drm_wait_vblank_reply as
DRM_IOCTL_WAIT_VBLANK, but still uses wall-clock time.

This converts it to using monotonic time as well, which is more
consistent, and avoids problems with the y2038 overflow as well
as synchronization issues when the real time skips.

I could not find the matching user space that calls the VIA_WAIT_IRQ
ioctl to verify that this is safe, but it very likely is. Please
either test or review the user space side before applying this.

In order to keep the dev_priv->ifbdev alive after failure, we have to
avoid the free and leave it empty until we unload the module (which is
less than ideal, but a necessary evil for simplicity). Then we can use
intel_fbdev_sync() to serialise the hotplug event with the configuration.
The serialisation between the two was removed in commit 934458c2c9
("Revert "drm/i915: Fix races on fbdev""), but the use after free is much
older, commit 366e39b4d2 ("drm/i915: Tear down fbdev if initialization

3452fa3095 drm/i915/pmu: Aggregate all RC6 states into one counter
Chris has discovered that RC6, RC6p and RC6pp counters are mutually
exclusive, and even that on some SNB SKUs you get RC6p increasing, and on
the others RC6.

Furthermore RC6p and RC6pp were only present starting from GEN6 until,
GEN7, not including Haswell.

All this combined makes it questionable whether we need to reserve new ABI
for these counters. One idea was to just combine them all under the RC6
counter to simplify things for userspace. So that is what this patch does.

a54b1873c0 drm/i915: Use exponential backoff for wait_for()
Instead of sleeping for a fixed 1ms (roughly, depending on timer slack),
start with a small sleep and exponentially increase the sleep on each
cycle.

A good example of a beneficiary is the guc mmio communication channel.
Typically we expect (and so spin) for 10us for a quick response, but this
doesn't cover everything and so sometimes we fallback to the millisecond+
sleep. This incurs a significant delay in time-critical operations like
preemption (igt/gem_exec_latency), which can be improved significantly by
using a small sleep after the spin fails.

We've made this suggestion many times, but had little experimental data
to support adding the complexity.

v2: Bump the minimum usleep to 10us on advice of
Documentation/timers/timers-howto.txt (Tvrko)
v3: Specify min, max range for usleep intervals -- some code may
crucially depend upon and so want to specify the sleep pattern.

8ee4f19c47 drm/i915/pmu: Stop averaging with the previous sample
Averaging with the previous sample brings a small statistical improvement
to sampling counters, but can leek a little bit of state from a current
client to the next which mulls the border between past and present for
observing clients.

This is because on event enable clients record the current counter value
and use it as reference, but with rapid off-on event cycles, and due the
delayed nature of sampling timer self-disarm, previous sample value does
not get cleared under these circumstances.

Solution is to stop averaging with the previous sample. This has a small
downside of losing some precision with short and spiky signals, but the
alternatives look too complicated for the benefit.

0426c04654 drm/i915/pmu: Only allow running on a single CPU
We do two things, both of which are purely to simplify and clarify the
implementation:

1.

Simplify the CPU online callback so it is more obvious that the purpose
there is to set a single CPU mask bit for the first CPU which comes
online. Using cpumask_weight for this reads more obvious than the trick
with cpumask_and_any.

2.

Modify the event init so that events can be created only on a single CPU.

This removes looking at the requested CPU thread siblings, and only allows
creating on the current active CPU.

e7e5da7127 drm/i915/selftests: Hold rpm wakeref for request + ggtt usage
Since the removal of the delayed rc6 enabling, we now setup and drop the
early rpm wakeref during modules initialisation before we start the live
selftests. As such, we are now detecting errors in the tests where we
were not holding the required wakeref for various actions. As rpm is not
the primary goal of the tests involved, take a coarse and convenient rpm
wakeref around the tests.

b7d3aabf90 drm/i915/pmu: Hide the (unsigned long)ptr cast
We pretend the PMU config id is a pointer value when encoding it into
the device parameters for presentation via sysfs. This requires casting
of an unsigned long into and out of the pointer member, which annoys
smatch:

drivers/gpu/drm/i915/i915_pmu.c:684 i915_pmu_event_show() warn: argument 3 to %lx specifier is cast from pointer

Instead of abusing a generic dev_ext_attribute, define our own typesafe
attributes.

   - remove the MSM dt-bindings file Rob managed to push in the previous

   - add a property/edid quirk to denote HMD devices, I had these
     hanging around for a few weeks and Keith had done some work on
     them, they are fairly self contained and small, and only affect
     people using HTC Vive VR headsets so far.

   - amdgpu, tegra, tilcdc, fsl fixes

   - some imx-drm cleanups I missed, these seemed pretty small, and no
     reason to hold off.

  I have one TTM regression fix (fixes bochs-vga in qemu) sitting

b1c24a6137 drm/i915: Unwind incomplete legacy context switches
The legacy context switch for ringbuffer submission is multistaged,
where each of those stages may fail. However, we were updating global
state after some stages, and so we had to force the incomplete request
to be submitted because we could not unwind. Save the global state
before performing the switches, and so enable us to unwind back to the
previous global state should any phase fail. We then must cancel the
request instead of submitting it should the construction fail.

This goes back to pre-atomic, where due to intermediate dpms states
connectors and encoder states might indeed not have matched.

With atomic that's all smashed together (and hopefully no bios ever
enables a vga output in dpms standby/suspedn state or we're toast).

sanitize_encoders was changed to disable the encoder in all cases,

42e5e65765 drm/i915: sync dp link status checks against atomic commmits
Two bits:
- check actual atomic state, the legacy stuff can only be looked at
  from within the atomic_commit_tail function, since it's only
  protected by ordering and not by any locks.

- Make sure we don't wreak the work an ongoing nonblocking commit is
  doing.

v2: We need the crtc lock too, because a plane update might change it
without having to acquire the connection_mutex (Maarten). Use
Maarten's changes for this locking, while keeping the logic that uses
the connection->commit->hw_done signal for syncing with nonblocking
commits.

v3: The initial state objects from the hw state readout do not have a
commit object. Check for that (spotted by CI).

v4: Fix deadlock from jumping to put_power with locks still held.

b552ae444e drm/i915/pmu: Drop I915_ENGINE_SAMPLE_MAX from uapi headers
We have agreed during the engine classes discussion that fields marked as
non-ABI are better left out altogether from uapi headers.

b8a3365a30 drm/vblank: Pass crtc_id to page_flip_ioctl.
We added crtc_id to the atomic ioctl, but forgot to add it for vblank
and page flip events. Commit bd386e5180 ("drm: Reorganize
drm_pending_event to support future event types [v2]") added it to
the vblank event, but page flip event was still missing.

Correct this and add a test for making sure we always set crtc_id correctly.

b4e3c935b2 drm/i915: Save/restore irq state for vlv_residency_raw()
Since commit 6060b6aec0 ("drm/i915/pmu: Add RC6 residency metrics"),
vlv_residency_raw() may be called from an irq-disabled context (via perf
event sampling on remote cpu). As such, we can no longer assume that we
are called from process context and must save/restore the irq state for
the spinlock.

f1781e9bb2 drm/edid: Allow HDMI infoframe without VIC or S3D
Appedix F of HDMI 2.0 says that some HDMI sink may fail to switch from
3D to 2D mode in a timely fashion if the source simply stops sending the
HDMI infoframe. The suggested workaround is to keep sending the
infoframe even when strictly not necessary (ie. no VIC and no S3D).
HDMI 1.4 does allow for this behaviour, stating that sending the
infoframe is optional in this case.

The infoframe was first specified in HDMI 1.4, so in theory sinks
predating that may not appreciate us sending an uknown infoframe
their way. To avoid regressions let's try to determine if the sink
supports the infoframe or not. Unfortunately there's no direct way
to do that, so instead we'll just check if we managed to parse any
HDMI 1.4 4k or stereo modes from the EDID, and if so we assume the
sink will accept the infoframe. Also if the EDID contains the HDMI
2.0 HDMI Forum VSDB we can assume the sink is prepared to receive
the infoframe.

v2: Fix getting has_hdmi_infoframe from display_info
    Always fail constructing the infoframe if the display
    possibly can't handle it

b3add01ee2 drm/i915/pmu: Wire up engine busy stats to PMU
We can use engine busy stats instead of the sampling timer for
better accuracy.

By doing this we replace the stohastic sampling with busyness
metric derived directly from engine activity. This is context
switch interrupt driven, so as accurate as we can get from
software tracking.

As a secondary benefit, we can also not run the sampling timer
in cases only busyness metric is enabled.

v2: Rebase.
v3:
 * Rebase, comments.
 * Leave engine busyness controls out of workers.
v4: Checkpatch cleanup.

30e17b7847 drm/i915: Engine busy time tracking
Track total time requests have been executing on the hardware.

We add new kernel API to allow software tracking of time GPU
engines are spending executing requests.

Both per-engine and global API is added with the latter also
being exported for use by external users.

v2:
 * Squashed with the internal API.
 * Dropped static key.
 * Made per-engine.
 * Store time in monotonic ktime.

v3: Moved stats clearing to disable.

v4:
 * Comments.
 * Don't export the API just yet.

v5: Whitespace cleanup.

v6:
 * Rename ref to active.
 * Drop engine aggregate stats for now.
 * Account initial busy period after enabling stats.

v7:
 * Rebase.

v8:
 * Move context in notification after the notifier. (Chris Wilson)

v9:

In cases where stats tracking is getting disabled while there is
an active context on an engine, add up the current value to the
total. This also implies we don't clear the total when tracking
is disabled any longer. There is no real need to do so because
we define the stats as relative while enabled, meaning
comparison between two samples while tracking is enabled is the
valid usage. However, when busy stats will later be plugged into
the perf PMU API, it is beneficial to not reset the total, since
the PMU core likes to do some counter disable/enable cycles on
startup, and while doing so during a single long context
executing on an engine we would lose some accuracy and so make
unit testing more difficult than needs to be.

v10:
 * Fix accounting for preemption.

v11:
 * Rebase for i915_modparams.enable_execlists removal.

b46a33e271 drm/i915/pmu: Expose a PMU interface for perf queries
From: Chris Wilson <chris@chris-wilson.co.uk>
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
From: Dmitry Rogozhkin <dmitry.v.rogozhkin@intel.com>

The first goal is to be able to measure GPU (and invidual ring) busyness
without having to poll registers from userspace. (Which not only incurs
holding the forcewake lock indefinitely, perturbing the system, but also
runs the risk of hanging the machine.) As an alternative we can use the
perf event counter interface to sample the ring registers periodically
and send those results to userspace.

Functionality we are exporting to userspace is via the existing perf PMU
API and can be exercised via the existing tools. For example:

  perf stat -a -e i915/rcs0-busy/ -I 1000

Will print the render engine busynnes once per second. All the performance
counters can be enumerated (perf list) and have their unit of measure
correctly reported in sysfs.

v1-v2 (Chris Wilson):

v2: Use a common timer for the ring sampling.

v3: (Tvrtko Ursulin)
 * Decouple uAPI from i915 engine ids.
 * Complete uAPI defines.
 * Refactor some code to helpers for clarity.
 * Skip sampling disabled engines.
 * Expose counters in sysfs.
 * Pass in fake regs to avoid null ptr deref in perf core.
 * Convert to class/instance uAPI.
 * Use shared driver code for rc6 residency, power and frequency.

v4: (Dmitry Rogozhkin)
 * Register PMU with .task_ctx_nr=perf_invalid_context
 * Expose cpumask for the PMU with the single CPU in the mask
 * Properly support pmu->stop(): it should call pmu->read()
 * Properly support pmu->del(): it should call stop(event, PERF_EF_UPDATE)
 * Introduce refcounting of event subscriptions.
 * Make pmu.busy_stats a refcounter to avoid busy stats going away
   with some deleted event.
 * Expose cpumask for i915 PMU to avoid multiple events creation of
   the same type followed by counter aggregation by perf-stat.
 * Track CPUs getting online/offline to migrate perf context. If (likely)
   cpumask will initially set CPU0, CONFIG_BOOTPARAM_HOTPLUG_CPU0 will be
   needed to see effect of CPU status tracking.
 * End result is that only global events are supported and perf stat
   works correctly.
 * Deny perf driver level sampling - it is prohibited for uncore PMU.

v5: (Tvrtko Ursulin)

 * Don't hardcode number of engine samplers.
 * Rewrite event ref-counting for correctness and simplicity.
 * Store initial counter value when starting already enabled events
   to correctly report values to all listeners.
 * Fix RC6 residency readout.
 * Comments, GPL header.

v6:
 * Add missing entry to v4 changelog.
 * Fix accounting in CPU hotplug case by copying the approach from
   arch/x86/events/intel/cstate.c. (Dmitry Rogozhkin)

v7:
 * Log failure message only on failure.
 * Remove CPU hotplug notification state on unregister.

v8:
 * Fix error unwind on failed registration.
 * Checkpatch cleanup.

v9:
 * Drop the energy metric, it is available via intel_rapl_perf.
   (Ville Syrjälä)
 * Use HAS_RC6(p). (Chris Wilson)
 * Handle unsupported non-engine events. (Dmitry Rogozhkin)
 * Rebase for intel_rc6_residency_ns needing caller managed
   runtime pm.
 * Drop HAS_RC6 checks from the read callback since creating those
   events will be rejected at init time already.
 * Add counter units to sysfs so perf stat output is nicer.
 * Cleanup the attribute tables for brevity and readability.

v10:
 * Fixed queued accounting.

v11:
 * Move intel_engine_lookup_user to intel_engine_cs.c
 * Commit update. (Joonas Lahtinen)

v12:
 * More accurate sampling. (Chris Wilson)
 * Store and report frequency in MHz for better usability from
   perf stat.
 * Removed metrics: queued, interrupts, rc6 counters.
 * Sample engine busyness based on seqno difference only
   for less MMIO (and forcewake) on all platforms. (Chris Wilson)

v13:
 * Comment spelling, use mul_u32_u32 to work around potential GCC
   issue and somne code alignment changes. (Chris Wilson)

v14:
 * Rebase.

v15:
 * Rebase for RPS refactoring.

v16:
 * Use the dynamic slot in the CPU hotplug state machine so that we are
   free to setup our state as multi-instance. Previously we were re-using
   the CPUHP_AP_PERF_X86_UNCORE_ONLINE slot which is neither used as
   multi-instance, nor owned by our driver to start with.
 * Register the CPU hotplug handlers after the PMU, otherwise the callback
   will get called before the PMU is initialized which can end up in
   perf_pmu_migrate_context with an un-initialized base.
 * Added workaround for a probable bug in cpuhp core.

v17:
 * Remove workaround for the cpuhp bug.

v18:
 * Rebase for drm_i915_gem_engine_class getting upstream before us.

v19:
 * Rebase. (trivial)

e99e88a9d2 treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.

Casting from unsigned long:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, ptr);

and forced object casts:

    void my_callback(struct something *ptr)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);

become:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

Direct function assignments:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    ptr->my_timer.function = my_callback;

have a temporary cast added, along with converting the args:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;

And finally, callbacks without a data assignment:

    void my_callback(unsigned long data)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, 0);

have their argument renamed to verify they're unused during conversion:

    void my_callback(struct timer_list *unused)
    {
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

The conversion is done with the following Coccinelle script:

spatch --very-quiet --all-includes --include-headers \
	-I ./arch/x86/include -I ./arch/x86/include/generated \
	-I ./include -I ./arch/x86/include/uapi \

b9eaf18722 treewide: init_timer() -> setup_timer()
This mechanically converts all remaining cases of ancient open-coded timer
setup with the old setup_timer() API, which is the first step in timer
conversions. This has no behavioral changes, since it ultimately just
changes the order of assignment to fields of struct timer_list when
finding variations of:

    init_timer(&t);
    f.function = timer_callback;
    t.data = timer_callback_arg;

to be converted into:

    setup_timer(&t, timer_callback, timer_callback_arg);

The conversion is done with the following Coccinelle script, which
is an improved version of scripts/cocci/api/setup_timer.cocci, in the
following ways:
 - assignments-before-init_timer() cases
 - limit the .data case removal to the specific struct timer_list instance
 - handling calls by dereference (timer->field vs timer.field)

f9eb63b98c drm/i915/selftests: Avoid drm_gem_handle_create under struct_mutex
Despite us reloading the module around every selftest, the lockclasses
persist and the chains used in selftesting may then dictate how we are
allowed to nest locks during runtime testing. As such we have to be just
as careful, and in particular it turns out we are not allowed to nest
dev->object_name_lock (drm_gem_handle_create) inside dev->struct_mutex.

b1e01595a6 drm/i915: Redo plane sanitation during readout
Unify the plane disabling during state readout by pulling the code into
a new helper intel_plane_disable_noatomic(). We'll also read out the
state of all planes, so that we know which planes really need to be
diabled.

Additonally we change the plane<->pipe mapping sanitation to work by
simply disabling the offending planes instead of entire pipes. And
we do it before we otherwise sanitize the crtcs, which means we don't
have to worry about misassigned planes during crtc sanitation anymore.

3572f04c69 drm/i915: Fix init_clock_gating for resume
Moving the init_clock_gating() call from intel_modeset_init_hw() to
intel_modeset_gem_init() had an unintended effect of not applying
some workarounds on resume. This, for example, cause some kind of
corruption to appear at the top of my IVB Thinkpad X1 Carbon LVDS
screen after hibernation. Fix the problem by explicitly calling
init_clock_gating() from the resume path.

I really hope this doesn't break something else again. At least
the problems reported at https://bugs.freedesktop.org/show_bug.cgi?id=103549
didn't make a comeback, even after a hibernate cycle.

6e068270b7 drm/i915: Clear breadcrumb node when cancelling signaling
When we call intel_engine_cancel_signaling() to stop reporting when
a request is completed via an asynchronous signal, we remove that request
from the breadcrumb wait queue. However, we may be concurrently
processing that request in the signaler itself, the actual operations on
the request's node itself are serialised but we do not actually clear the
waiter after removing it from the tree allowing both parties to attempt
to do so and corrupting the rbtree. (Previously removing from the
breadcrumb wait queue could only be done on behalf of i915_wait_request,
so this race could not happen).

f4359cedfb drm/i915: Fix false-positive assert_rpm_wakelock_held in i915_pmic_bus_access_notifier v2
assert_rpm_wakelock_held is triggered from i915_pmic_bus_access_notifier
even though it gets unregistered on (runtime) suspend, this is caused
by a race happening under the following circumstances:

intel_runtime_pm_put does:

   atomic_dec(&dev_priv->pm.wakeref_count);

   pm_runtime_mark_last_busy(kdev);
   pm_runtime_put_autosuspend(kdev);

And pm_runtime_put_autosuspend calls intel_runtime_suspend from
a workqueue, so there is ample of time between the atomic_dec() and
intel_runtime_suspend() unregistering the notifier. If the notifier
gets called in this windowd assert_rpm_wakelock_held falsely triggers
(at this point we're not runtime-suspended yet).

This commit adds disable_rpm_wakeref_asserts and
enable_rpm_wakeref_asserts calls around the
intel_uncore_forcewake_get(FORCEWAKE_ALL) call in
i915_pmic_bus_access_notifier fixing the false-positive WARN_ON.

Changes in v2:
-Reword comment explaining why disabling the wakeref asserts is
 ok and necessary

0da715ee60 drm/i915: Disable semaphores on Sandybridge
I should have admitted defeat long ago as there has been a rare but
persistent error on Sandybridge where semaphore signaling did not
propagate to the waiter, leading to a GPU hang.

With the work on fence signaling for v4.9, the impact of using CPU driven
signaling was greatly reduced wrt to the latency of GPU semaphores,
though without logical rings support, the benefit of reordering work to
avoid bubbles is not realised (i.e. as it stands fence signaling is just
a slower, more costly version of HW semaphores; but works more
consistently). As a rough indicator of the difference,

with semaphores:
Sequential (3 engines, 1 processes): average 5.470us per cycle [expected 4.988us]
w/o semaphores:
Sequential (3 engines, 1 processes): average 15.771us per cycle [expected 4.923us]

In comparison, v3.4:
with semaphores:
Sequential (3 engines, 1 processes): average 16.066us per cycle [expected 11.842us]
w/o semaphores:
Sequential (3 engines, 1 processes): average 23.460us per cycle [expected 11.839us]

79e6770cb1 drm/i915: Remove obsolete ringbuffer emission for gen8+
Since removing the module parameter to force selection of ringbuffer
emission for gen8, the code is defunct. Remove it.

To put the difference into perspective, a couple of microbenchmarks
(bdw i7-5557u, 20170324):
                                        ring          execlists
exec continuous nops on all rings:   1.491us            2.223us
exec sequential nops on each ring:  12.508us           53.682us
single nop + sync:                   9.272us           30.291us

vblank_mode=0 glxgears:            ~11000fps           ~9000fps

Since the earlier submission, gen8 ringbuffer submission has fallen
further and further behind in features. So while ringbuffer may hold the
throughput crown, in terms of interactive latency, execlists is much
better. Alas, we have no convenient metrics for such, other than
demonstrating things we can do with execlists but can not using
legacy ringbuffer submission.

We have made a few improvements to lowlevel execlists throughput,
and ringbuffer currently panics on boot! (bdw i7-5557u, 20171026):

                                        ring          execlists
exec continuous nops on all rings:       n/a            1.921us
exec sequential nops on each ring:       n/a           44.621us
single nop + sync:                       n/a           21.953us

10b47ee02d drm: Check crtc_state->enable rather than crtc->enabled in drm_plane_helper_check_state()
drm_plane_helper_check_state() is supposed to do things the atomic way,
so it should not be inspecting crtc->enabled. Rather we should be
looking at crtc_state->enable.

We have a slight complication due to drm_plane_helper_check_update()
reusing drm_plane_helper_check_state() for non-atomic drivers. Thus
we'll have to pass the crtc_state in manally and construct a fake
crtc_state in drm_plane_helper_check_update().

v2: Fix the WARNs about plane_state->crtc matching crtc_state->crtc

ba74cb10c7 drm/i915/execlists: Delay writing to ELSP until HW has processed the previous write
The hardware needs some time to process the information received in the
ExecList Submission Port, and expects us to not write anything more until
it has 'acknowledged' this new submission by sending an IDLE_ACTIVE or
PREEMPTED CSB event.

If we do not follow this, the driver could write new data into the ELSP
before HW had finishing fetching the previous one, putting us in
'undefined behaviour' space.

This seems to be the problem causing the spurious PREEMPTED & COMPLETE
events after a COMPLETE like the one below:

[] vcs0: sw rd pointer = 2, hw wr pointer = 0, current 'head' = 3.
[] vcs0:  Execlist CSB[0]: 0x00000018 _ 0x00000007
[] vcs0:  Execlist CSB[1]: 0x00000001 _ 0x00000000
[] vcs0:  Execlist CSB[2]: 0x00000018 _ 0x00000007  <<< COMPLETE
[] vcs0:  Execlist CSB[3]: 0x00000012 _ 0x00000007  <<< PREEMPTED & COMPLETE
[] vcs0:  Execlist CSB[4]: 0x00008002 _ 0x00000006
[] vcs0:  Execlist CSB[5]: 0x00000014 _ 0x00000006

The ELSP writes that lead to this CSB sequence show that the HW hadn't
started executing the previous execlist (the one with only ctx 0x6) by the
time the new one was submitted; this is a bit more clear in the data
show in the EXECLIST_STATUS register at the time of the ELSP write.

[] vcs0: ELSP[0] = 0x0_0        [execlist1] - status_reg = 0x0_302
[] vcs0: ELSP[1] = 0x6_fedb2119 [execlist0] - status_reg = 0x0_8302

[] vcs0: ELSP[2] = 0x7_fedaf119 [execlist1] - status_reg = 0x0_8308
[] vcs0: ELSP[3] = 0x6_fedb2119 [execlist0] - status_reg = 0x7_8308

Note that having to wait for this ack does not disable lite-restores,
although it may reduce their numbers.

    drm/i915/bdw: Avoid non-lite-restore preemptions

execlists has listened to (ACTIVE_IDLE | ELEMENT_SWITCH) for detecting
when one context completed and it either continued onto the next (in port
1) or idled. We would always see COMPLETE | ACTIVE_IDLE on the final
context-switch event, but on recent gen it appears that we now get
separate ACTIVE_IDLE and COMPLETE events. In particular, the ACTIVE_IDLE
events may not be coupled to a context (since it is a general state rather
than a specific context completion event).

v2: Update the history, execlists did originally start out by listening
to the COMPLETE event not ACTIVE_IDLE.
v3: Update preempt completion test to also use COMPLETE not ACTIVE_IDLE.

675f7ff35b drm/i915: Fix init_clock_gating for resume

screen after hibernation. Fix the problem by explicitly calling
init_clock_gating() from the resume path.

the problems reported at https://bugs.freedesktop.org/show_bug.cgi?id=103549
didn't make a comeback, even after a hibernate cycle.

Pull amdgpu DC display code for Vega from Dave Airlie:
 "This is the pull request for the AMD DC (display code) layer which is
  a requirement to program the display engines on the new Vega and Raven
  based GPUs. It also contains support for all amdgpu supported GPUs
  (CIK, VI, Polaris), which has to be enabled. It is also a kms atomic
  modesetting compatible driver (unlike the current in-tree display
  code).

  I've kept it separate from drm-next because it may have some things
  that cause you to reject it.

  Background story:

  AMD have an internal team creating a shared OS codebase for display at
  hw bring up time using information from their hardware teams. This
  process doesn't lead to the most Linux friendly/looking code but we
  have worked together on cleaning a lot of it up and dealing with
  sparse/smatch/checkpatch, and having their team internally adhere to
  Linux coding standards.

  This tree is a complete history rebased since they started opening it,
  we decided not to squash it down as the history may have some value.
  Some of the commits therefore might not reach kernel standards, and we
  are steadily training people in AMD to better write commit msgs.

  There is a major bunch of generated bandwidth calculation and
  verification code that comes from their hardware team. On Vega and
  before this is float calculations, on Raven (DCN10) this is double
  based. They do the required things to do FP in the kernel, and I could
  understand this might raise some issues. Rewriting the bandwidth would
  be a major undertaken in reverification, it's non-trivial to work out
  if a display can handle the complete set of mode information thrown at
  it.

  Future story:

  There is a TODO list with this, and it address most of the remaining
  things that would be nice to refine/remove. The DCN10 code is still
  under development internally and they push out a lot of patches quite
  regularly and are supporting this code base with their display team. I
  think we've reached the point where keeping it out of tree is going to
  motivate distributions to start carrying the code, so I'd prefer we
  get it in tree. I think this code is slightly better than STAGING
  quality but not massively so, I'd really like to see that float/double
  magic gone and fixed point used, but AMD don't seem to think the
  accuracy and revalidation of the code is worth the effort"

6a7a6a982a drm/i915: Add a policy note for removing workarounds
Rodrigo gave a persuasive argument for keeping workarounds: that they
serve as a good guide for the bring up of the next generation. Not only
do workarounds persist into the early revisions, they show where the
workarounds were previously added to the code flow and sometimes the old
workarounds have an explanation that give insight into their wider
implications.

Based on his suggestion, document the policy that we want to keep the
workarounds from the current generation to guide the next. Older
preproduction workarounds we still want to remove to keep the code
clean.

223c73a366 drm/i915/selftests: Report ENOMEM clearly for an allocation failure
If we can not run the drunk_hole test because we couldn't allocate the
memory for the permutation array (even after we tried trimming the
size), report a clear ENOMEM. Similary, if we are asked to operate on a
hole too small for ourselves, make it skip quietly.

v2: Avoid malloc(0) since that returns ZERO_SIZE_PTR not NULL.
v3: Fixup similar construction for lowlevel_hole
v4: Use u64 >> 1 to avoid 64b div.

248c2435cb drm/i915: Calculate g4x intermediate watermarks correctly
The watermarks it should calculate against are the old optimal watermarks.
The currently active crtc watermarks are pure fiction, and are invalid in
case of a nonblocking modeset, page flip enabling/disabling planes or any
other reason.

When the crtc is disabled or during a modeset the intermediate watermarks
don't need to be programmed separately, and could be directly assigned
to the optimal watermarks.

CXSR must always be disabled in the intermediate case for modesets,
else we get a WARN for vblank wait timeout.

33a49868e5 drm/i915: Enable FIFO underrun reporting after initial fastset, v4.
The firmware may have set up the pipe correctly, but the FIFO
underrun and CRC interrupts are likely not enabled.

This resulted in debugfs_test.read_all_entries failing on haswell,
because of a timeout when reading the crc debugfs entry.

Solve this by enabling FIFO underrun reporting after the initial
fastset, which lets interrupts be generated as expected.

Changes since v1:
- Always enable CPU FIFO underrun reporting for >GEN2,
  and handle GEN2 correctly.
Changes since v2:
- Remove unneeded HAS_DDI, simplify GEN2 case.
Changes since v3:
- Use intel_crtc_pch_transcoder to determine pch transcoder for underruns. (Ville)
- Remove crtc->config dereference in intel_crtc_pch_transcoder. (Ville)

55bd6bd757 drm/i915/selftests: Add a GuC doorbells selftest
The first test aims to check guc_init_doorbell_hw, changing the existing
guc clients and doorbells state before calling it.

The second test tries to create as many clients as it is currently possible
(currently limited to max number of doorbells) and exercise the doorbell
alloc/dealloc code.

Since our usage mode require very few clients/doorbells, this code has
been exercised very lightly and it's good to have a simple test for it.

As reference, this test already helped identify the bug fixed by
commit 7f1ea2ac30 ("drm/i915/guc: Fix doorbell id selection").

v2: Extend number of clients; check for client allocation failure when
number of doorbells is exceeded; validate client properties; reuse
guc_init_doorbell_hw (Chris).

v3: guc_init_doorbell_hw test added per Chris suggestion.

v4: Try to explain why guc_init_doorbell_hw exist and comment some
details in the subtest.

v5: Remove redundant pr_info at the beginning of each subtest (Chris);
rebase (s/i915_guc_client/intel_guc_client/).

Merge tag 'afs-next-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull AFS updates from David Howells:
 "kAFS filesystem driver overhaul.

  The major points of the overhaul are:

   (1) Preliminary groundwork is laid for supporting network-namespacing
       of kAFS. The remainder of the namespacing work requires some way
       to pass namespace information to submounts triggered by an
       automount. This requires something like the mount overhaul that's
       in progress.

   (2) sockaddr_rxrpc is used in preference to in_addr for holding
       addresses internally and add support for talking to the YFS VL
       server. With this, kAFS can do everything over IPv6 as well as
       IPv4 if it's talking to servers that support it.

   (3) Callback handling is overhauled to be generally passive rather
       than active. 'Callbacks' are promises by the server to tell us
       about data and metadata changes. Callbacks are now checked when
       we next touch an inode rather than actively going and looking for
       it where possible.

   (4) File access permit caching is overhauled to store the caching
       information per-inode rather than per-directory, shared over
       subordinate files. Whilst older AFS servers only allow ACLs on
       directories (shared to the files in that directory), newer AFS
       servers break that restriction.

       To improve memory usage and to make it easier to do mass-key
       removal, permit combinations are cached and shared.

   (5) Cell database management is overhauled to allow lighter locks to
       be used and to make cell records autonomous state machines that
       look after getting their own DNS records and cleaning themselves
       up, in particular preventing races in acquiring and relinquishing
       the fscache token for the cell.

   (6) Volume caching is overhauled. The afs_vlocation record is got rid
       of to simplify things and the superblock is now keyed on the cell
       and the numeric volume ID only. The volume record is tied to a
       superblock and normal superblock management is used to mediate
       the lifetime of the volume fscache token.

   (7) File server record caching is overhauled to make server records
       independent of cells and volumes. A server can be in multiple
       cells (in such a case, the administrator must make sure that the
       VL services for all cells correctly reflect the volumes shared
       between those cells).

       Server records are now indexed using the UUID of the server
       rather than the address since a server can have multiple
       addresses.

   (8) File server rotation is overhauled to handle VMOVED, VBUSY (and
       similar), VOFFLINE and VNOVOL indications and to handle rotation
       both of servers and addresses of those servers. The rotation will
       also wait and retry if the server says it is busy.

   (9) Data writeback is overhauled. Each inode no longer stores a list
       of modified sections tagged with the key that authorised it in
       favour of noting the modified region of a page in page->private
       and storing a list of keys that made modifications in the inode.

       This simplifies things and allows other keys to be used to
       actually write to the server if a key that made a modification
       becomes useless.

  (10) Writable mmap() is implemented. This allows a kernel to be build
       entirely on AFS.

  Note that Pre AFS-3.4 servers are no longer supported, though this can
  be added back if necessary (AFS-3.4 was released in 1998)"

063c886197 drm/i915/cnl: Fix wrpll math for higher freqs.
Spec describe all values in MHz. We handle our
clocks in KHz. This includes the best_dco_centrality that was
forgot in the same unity as spec. Consequently we couldn't
get a good divider for high frequenies. Hence HDMI 2.0 wasn't
working.

Spec tells 999999 for initial best_dco_centrality meaning the
max value in MHz.
Since we convert dco from MHz to KHz we also need to convert
this initial best_doc_centrality to 999999000 or 999999999
or even better, to the max that its variable allow.

This patch also replaces the use of "* KHz(1)" with the values
directly on KHz to avoid future confusion.

v2: Use U32_MAX instead of random 99999 as spec tells. (Ville).
