f16e9bfb57 drm/rockchip: Don't spam logs in atomic check
commit 43dae319b5 upstream.

Userspace should not be able to trigger DRM_ERROR messages to spam the

bd7b1430a2 drm/nouveau: remove unused tu102_gr_load() function
commit 421dabcad1 upstream.

tu102_gr_load() is completely unused and can be removed to address
this warning:

drivers/gpu/drm/nouveau/dispnv50/disp.c:2517:1: error: no previous prototype for 'nv50_display_create'

Another patch was sent in the meantime to mark the function static but
that would just cause a different warning about an unused function.

7eacde7fb9 drm/bridge: it6505: Check power state with it6505->powered in IRQ handler
commit e9d699af3f upstream.

On system resume, the driver might call it6505_poweron directly if the
runtime PM hasn't been enabled. In such case, pm_runtime_get_if_in_use
will always return 0 because dev->power.runtime_status stays at
RPM_SUSPENDED, and the IRQ will never be handled.

Use it6505->powered from the driver struct fixes this because it always
gets updated when it6505_poweron is called.

e41bc6e0ec drm/nouveau/disp: Revert a NULL check inside nouveau_connector_get_modes

The original commit adding that check tried to protect the kenrel against
a potential invalid NULL pointer access.

However we call nouveau_connector_detect_depth once without a native_mode

349a7b42bc drm/amd: Disable S/G for APUs when 64GB or more host memory
commit 08fffa74d9 upstream.

Users report a white flickering screen on multiple systems that
is tied to having 64GB or more memory.  When S/G is enabled pages
will get pinned to both VRAM carve out and system RAM leading to
this.

Until it can be fixed properly, disable S/G when 64GB of memory or
more is detected.  This will force pages to be pinned into VRAM.
This should fix white screen flickers but if VRAM pressure is
encountered may lead to black screens.  It's a trade-off for now.

implementation just have nothing special to do and leave vm_ops

is the case with the system_heap implementation for instance).
Let's reset vma->vm_ops to NULL to keep things working with these

ab4ae028f9 drm/nouveau/nvkm/dp: Add workaround to fix DP 1.3+ DPCD issues
commit e4060dad25 upstream.

Currently we use the drm_dp_dpcd_read_caps() helper in the DRM side of
nouveau in order to read the DPCD of a DP connector, which makes sure we do
the right thing and also check for extended DPCD caps. However, it turns
out we're not currently doing this on the nvkm side since we don't have
access to the drm_dp_aux structure there - which means that the DRM side of
the driver and the NVKM side can end up with different DPCD capabilities
for the same connector.

Ideally in order to fix this, we just want to use the
drm_dp_read_dpcd_caps() helper in nouveau. That's not currently possible
though, and is going to depend on having a bunch of the DP code moved out
of nvkm and into the DRM side of things as part of the GSP enablement work.

Until then however, let's workaround this problem by porting a copy of
drm_dp_read_dpcd_caps() into NVKM - which should fix this issue.

1092c929bb drm/nouveau/gr: enable memory loads on helper invocation on all channels
commit 1cb9e2ef66 upstream.

We have a lurking bug where Fragment Shader Helper Invocations can't load
from memory. But this is actually required in OpenGL and is causing random
hangs or failures in random shaders.

It is unknown how widespread this issue is, but shaders hitting this can
end up with infinite loops.

We enable those only on all Kepler and newer GPUs where we use our own
Firmware.

Nvidia's firmware provides a way to set a kernelspace controlled list of
mmio registers in the gr space from push buffers via MME macros.

v2: drop code for gm200 and newer.

61977b1526 drm/imx/ipuv3: Fix front porch adjustment upon hactive aligning
[ Upstream commit ee31742bf1 ]

When hactive is not aligned to 8 pixels, it is aligned accordingly and
hfront porch needs to be reduced the same amount. Unfortunately the front
porch is set to the difference rather than reducing it. There are some
Samsung TVs which can't cope with a front porch of instead of 70.

ed7ac41cfc drm/i915: Fix premature release of request's reusable memory
commit a337b64f0d upstream.

Infinite waits for completion of GPU activity have been observed in CI,
mostly inside __i915_active_wait(), triggered by igt@gem_barrier_race or
igt@perf@stress-open-close.  Root cause analysis, based of ftrace dumps
generated with a lot of extra trace_printk() calls added to the code,
revealed loops of request dependencies being accidentally built,
preventing the requests from being processed, each waiting for completion
of another one's activity.

After we substitute a new request for a last active one tracked on a
timeline, we set up a dependency of our new request to wait on completion
of current activity of that previous one.  While doing that, we must take
care of keeping the old request still in memory until we use its
attributes for setting up that await dependency, or we can happen to set
up the await dependency on an unrelated request that already reuses the
memory previously allocated to the old one, already released.  Combined
with perf adding consecutive kernel context remote requests to different
user context timelines, unresolvable loops of await dependencies can be
built, leading do infinite waits.

We obtain a pointer to the previous request to wait upon when we
substitute it with a pointer to our new request in an active tracker,
e.g. in intel_timeline.last_request.  In some processing paths we protect
that old request from being freed before we use it by getting a reference
to it under RCU protection, but in others, e.g.  __i915_request_commit()
-> __i915_request_add_to_timeline() -> __i915_request_ensure_ordering(),
we don't.  But anyway, since the requests' memory is SLAB_FAILSAFE_BY_RCU,
that RCU protection is not sufficient against reuse of memory.

We could protect i915_request's memory from being prematurely reused by
calling its release function via call_rcu() and using rcu_read_lock()
consequently, as proposed in v1.  However, that approach leads to
significant (up to 10 times) increase of SLAB utilization by i915_request
SLAB cache.  Another potential approach is to take a reference to the
previous active fence.

When updating an active fence tracker, we first lock the new fence,
substitute a pointer of the current active fence with the new one, then we
lock the substituted fence.  With this approach, there is a time window
after the substitution and before the lock when the request can be
concurrently released by an interrupt handler and its memory reused, then
we may happen to lock and return a new, unrelated request.

Always get a reference to the current active fence first, before
replacing it with a new one.  Having it protected from premature release
and reuse, lock it and then replace with the new one but only if not
yet signalled via a potential concurrent interrupt nor replaced with
another one by a potential concurrent thread, otherwise retry, starting
from getting a reference to the new current one.  Adjust users to not
get a reference to the previous active fence themselves and always put the
reference got by __i915_active_fence_set() when no longer needed.

v3: Fix lockdep splat reports and other issues caused by incorrect use of
    try_cmpxchg() (use (cmpxchg() != prev) instead)
v2: Protect request's memory by getting a reference to it in favor of
    delegating its release to call_rcu() (Chris)

the hw_fence pointer is simply a kzalloc'd block of memory.  In this
case we should just kfree() it, rather than trying to decrement it's

checking for a zero refcount, since if the job was run, the submit would
be holding a reference to the hw_fence.

Only set vtotal to the crtc adjustment vtotal_min value
in cases where the value is non-zero.

8e2fd3a158 drm/amd/display: update extended blank for dcn314 onwards
[ Upstream commit 469a62938a ]

[Why]
Flickering and underflow was observed when testing extended
blank on dcn314.

[What]
Vstartup is contrainted by vblank_nom, so adjusting it to include
non-adjusted vtotal in its calculation during freesync video
means that Vstartup is not changed when vtotal changes.
This fixed the flickering + underflow.

dc_extended_blank_supported function was removed
because extended blank is only relevant to when
zstate is supported. The increased vtotal during
freesync can be passed to dml regardless of whether
extended blank is supported or not, so this function is
not needed.

Updates were made recently in dml to the calculation of
min_dst_y_next_start. Dml input for dcn314 will now
always use the newer calculation for min_dst_y_next_start.
Dml input for older dcn versions remains untouched.

The variable optimized_min_dst_y_next_start
is replaced everywhere with min_dst_y_next_start,
and the updated dml allows min_dst_y_next_start to
increase to an optimized value during freesync video,
then return to default when freesync is disengaged.

Also removed registry key for controlling
extended blank feature.
