The plane buffer address/stride/height was incorrectly updated in the
plane_atomic_update operation instead of the vsync irq.
This patch delays this operation in the vsync irq along with the
other plane delayed setup.
This issue was masked using legacy framebuffer and X11 modesetting, but
is clearly visible using gbm rendering when buffer is submitted late after
vblank, like using software decoding and OpenGL rendering in Kodi.
With this patch, tearing and other artifacts disappears completely.

During eviction, the driver may free more than one hole in the drm_mm
due to the side-effects in evicting the scanned nodes. However,
drm_mm_scan_color_evict() expects that the scan result is the first
available hole (in the mru freed hole_stack list):

We can trivially relax this assumption by searching the hole_stack for
the scan result and warn instead if the driver called us without any

Bit field [2:0] of HDMI_I2S_PIN_SEL_1 corresponds to SDATA_0,
not SDATA_2. This patch removes redefinition of HDMI_I2S_SEL_DATA2
constant and adds missing HDMI_I2S_SEL_DATA0.
The value of bit field selecting SDATA_1 (pin_sel_3) is also changed,
so it is 3 as suggested in the Exynos TRMs.

The exynos DRM driver uses real-time 'struct timeval' values
for exporting its timestamps to user space. This has multiple
problems:
1. signed seconds overflow in y2038
2. the 'struct timeval' definition is deprecated in the kernel
3. time may jump or go backwards after a 'settimeofday()' syscall
4. other DRM timestamps are in CLOCK_MONOTONIC domain, so they
can't be compared
5. exporting microseconds requires a division by 1000, which may
be slow on some architectures.
The code existed in two places before, but the IPP portion was
removed in 8ded59413ccc ("drm/exynos: ipp: Remove Exynos DRM
IPP subsystem"), so we no longer need to worry about it.
Ideally timestamps should just use 64-bit nanoseconds instead, but
of course we can't change that now. Instead, this tries to address
the first four points above by using monotonic 'timespec' values.
According to Tobias Jakobi, user space doesn't care about the
timestamp at the moment, so we can change the format. Even if
there is something looking at them, it will work just fine with
monotonic times as long as the application only looks at the
relative values between two events.

amdgpu's ->runtime_suspend hook calls drm_kms_helper_poll_disable(),
which waits for the output poll worker to finish if it's running.
The output poll worker meanwhile calls pm_runtime_get_sync() in
amdgpu's ->detect hooks, which waits for the ongoing suspend to finish,
causing a deadlock.
Fix by not acquiring a runtime PM ref if the ->detect hooks are called
in the output poll worker's context. This is safe because the poll

Introduce a helper to determine if the current task is an output poll
worker.
This allows us to fix a long-standing deadlock in several DRM drivers
wherein the ->runtime_suspend callback waits for the output poll worker
to finish and the worker in turn calls a ->detect callback which waits
for runtime suspend to finish. The ->detect callback is invoked from
multiple call sites and waiting for runtime suspend to finish is the
correct thing to do except if it's executing in the context of the
worker.
v2: Expand kerneldoc to specifically mention deadlock between
output poll worker and autosuspend worker as use case. (Lyude)

drm/amdgpu: add new device to use atpx quirk
|

So far models of the Dell Venue 8 Pro, with a panel with MIPI panel
index = 3, one of which has been kindly provided to me by Jan Brummer,
where not working with the i915 driver, giving a black screen on the
first modeset.
The problem with at least these Dells is that their VBT defines a MIPI
ASSERT sequence, but not a DEASSERT sequence. Instead they DEASSERT the
reset in their INIT_OTP sequence, but the deassert must be done before
calling intel_dsi_device_ready(), so that is too late.
Simply doing the INIT_OTP sequence earlier is not enough to fix this,
because the INIT_OTP sequence also sends various MIPI packets to the
panel, which can only happen after calling intel_dsi_device_ready().
This commit fixes this by splitting the INIT_OTP sequence into everything
before the first DSI packet and everything else, including the first DSI
packet. The first part (everything before the first DSI packet) is then
used as deassert sequence.
Changed in v2:
-Split the init OTP sequence into a deassert reset and the actual init
OTP sequence, instead of calling it earlier and then having the first
mipi_exec_send_packet() call call intel_dsi_device_ready().
Changes in v3:
-Move the whole shebang to intel_bios.c

At least on the Chuwi Vi8 (non pro/plus) the LCD panel will show an image
shifted aprox. 20% to the left (with wraparound) and sometimes also wrong
colors, showing that the panel controller is starting with sampling the
datastream somewhere mid-line. This happens after the first blanking and
re-init of the panel.
After looking at drm.debug output I noticed that initially we inherit the
cdclk of 333333 KHz set by the GOP, but after the re-init we picked 266667
KHz, which turns out to be the cause of this problem, a quick hack to hard
code the cdclk to 333333 KHz makes the problem go away.
I've tested this on various Bay Trail devices, to make sure this not does
cause regressions on other devices and the higher cdclk does not cause
any problems on the following devices:
-GP-electronic T701 1024x600 333333 KHz cdclk after this patch
-PEAQ C1010 1920x1200 333333 KHz cdclk after this patch
-PoV mobii-wintab-800w 800x1280 333333 KHz cdclk after this patch
-Asus Transformer-T100TA 1368x768 320000 KHz cdclk after this patch
Also interesting wrt this is the comment in vlv_calc_cdclk about the
existing workaround to avoid 200 Mhz as clock because that causes issues
in some cases.
This commit extends the "do not use 200 Mhz" workaround with an extra
check to require atleast 320000 KHz (avoiding 266667 KHz) when a DSI
panel is active.
Changes in v2:

a reference, the GOP should not be treated as a reference

GGTT is in BAR0 with 8 bytes aligned. With a qemu patch (commit:
38d49e8c1523d97d2191190d3f7b4ce7a0ab5aa3), VFIO can use 8-byte reads/
writes to access it.
This patch is to support the 8-byte GGTT reads/writes.
Ideally, we would like to support 8-byte reads/writes for the total BAR0.
But it needs more work for handling 8-byte MMIO reads/writes.
This patch can fix the issue caused by partial updating GGTT entry, during
guest booting up.
v3:
- Use intel_vgpu_get_bar_gpa() stead. (Zhenyu)

We are not allowed to call intel_runtime_pm_get from the PMU counter read
callback since the former can sleep, and the latter is running under IRQ
context.
To workaround this, we record the last known RC6 and while runtime
suspended estimate its increase by querying the runtime PM core
timestamps.
Downside of this approach is that we can temporarily lose a chunk of RC6
time, from the last PMU read-out to runtime suspend entry, but that will
eventually catch up, once device comes back online and in the presence of
PMU queries.
Also, we have to be careful not to overshoot the RC6 estimate, so once
resumed after a period of approximation, we only update the counter once
it catches up. With the observation that RC6 is increasing while the
device is suspended, this should not pose a problem and can only cause
slight inaccuracies due clock base differences.
v2: Simplify by estimating on top of PM core counters. (Imre)

Commit 99e48bf98dd0 ("drm/i915: Lock out execlist tasklet while peeking
inside for busy-stats") added a tasklet_disable call in busy stats
enabling, but we failed to understand that the PMU enable callback runs
as an hard IRQ (IPI).
Consequence of this is that the PMU enable callback can interrupt the
execlists tasklet, and will then deadlock when it calls
intel_engine_stats_enable->tasklet_disable.
To fix this, I realized it is possible to move the engine stats enablement
and disablement to PMU event init and destroy hooks. This allows for much
simpler implementation since those hooks run in normal context (can
sleep).
v2: Extract engine_event_destroy. (Chris Wilson)

In order to prevent a race condition where we may end up overaccounting
the active state and leaving the busy-stats believing the GPU is 100%
busy, lock out the tasklet while we reconstruct the busy state. There is
no direct spinlock guard for the execlists->port[], so we need to
utilise tasklet_disable() as a synchronous barrier to prevent it, the
only writer to execlists->port[], from running at the same time as the
enable.

When a request is preempted, it is unsubmitted from the HW queue and
removed from the active list of breadcrumbs. In the process, this
however triggers the signaler and it may see the clear rbtree with the
old, and still valid, seqno, or it may match the cleared seqno with the
now zero rq->global_seqno. This confuses the signaler into action and
signaling the fence.

This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:
for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
done
with de-mangling cleanups yet to come.
NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do. But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.
The next patch from Al will sort out the final differences, and we
should be all done.

- GP108 acceleration support is enabled by "secure boot" support
- some clockgating work on Kepler, and bunch of fixes
- the bulk of the diff is regenerated firmware files, the change to
them really isn't that large.
Otherwise this contains regular Intel and AMDGPU fixes"

git://anongit.freedesktop.org/drm/drm-intel into drm-next
Fix for pcode timeouts on BXT and GLK, cmdparser fixes and fixes
for new vbt version on CFL and CNL.
GVT contains vGPU reset enhancement, which refines vGPU reset flow
and the support of virtual aperture read/write when x-no-mmap=on
is set in KVM, which is required by a test case from Redhat and
also another fix for virtual OpRegion.
