 "DP quirk for usb c dongles.

  As mentioned I have a separate request for fixing a regression, but
  also keeping the broken hw working, for certain USB-C DP adapters they
  require a minimised n/m parameters, but an attempt to do this
  generically has failed, we need to quirk these specific adapters.
  However doing it generically regressed some eDP panels.

  This pull adds the infrastructure and a quirk for the adapter"

Jani Nikula b31e85eda3 drm/i915: Detect USB-C specific dongles before reducing M and N
The Analogix 7737 DP to HDMI converter requires reduced M and N values
when to operate correctly at HBR2. We tried to reduce the M/N values for
all devices in commit 9a86cda07a ("drm/i915/dp: reduce link M/N
parameters"), but that regressed some other sinks. Detect this IC by its
OUI value of 0x0022B9 via the DPCD quirk list, and only reduce the M/N
values for that.

Jani Nikula 76fa998acd drm/dp: start a DPCD based DP sink/branch device quirk database
Face the fact, there are Display Port sink and branch devices out there
in the wild that don't follow the Display Port specifications, or they
have bugs, or just otherwise require special treatment. Start a common
quirk database the drivers can query based on the DP device
identification. At least for now, we leave the workarounds for the
drivers to implement as they see fit.

For starters, add a branch device that can't handle full 24-bit main
link Mdiv and Ndiv main link attributes properly. Naturally, the
workaround of reducing main link attributes for all devices ended up in
regressions for other devices. So here we are.

v2: Rebase on DRM DP desc read helpers

Somehow the helper was never retrofitted for mdp5.  Which meant when
plane_state->fence was added, it could get copied into new state in

If an update to disable the plane (for example on rmfb) managed to sneak
in after an nonblock update had swapped state, but before it was
committed, we'd get a splat:

Ville Syrjälä 9bd9590997 drm/i915: Stop pretending to mask/unmask LPE audio interrupts
vlv_display_irq_postinstall() enables the LPE audio interrupts
regardless of whether the LPE audio irq chip has masked/unmasked
them. Also the irqchip masking/unmasking doesn't consider the state
of the display power well or the device, and hence just leads to
dmesg spew when it tries to access the hardware while it's powered
down.

If the current way works, then we don't need to do anything in the
mask/unmask hooks. If it doesn't work, well, then we'd need to properly
track whether the irqchip has masked/unmasked the interrupts when
we enable display interrupts. And the mask/unmask hooks would need
to check whether display interrupts are even enabled before frobbing
with he registers.

So let's just assume the current way works and neuter the mask/unmask
hooks. Also clean up vlv_display_irq_postinstall() a bit and stop
it from trying to unmask/enable the LPE C interrupt on VLV since it
doesn't exist.

Lyude 3d18e33735 drm/radeon: Unbreak HPD handling for r600+
We end up reading the interrupt register for HPD5, and then writing it
to HPD6 which on systems without anything using HPD5 results in
permanently disabling hotplug on one of the display outputs after the
first time we acknowledge a hotplug interrupt from the GPU.

This code is really bad. But for now, let's just fix this. I will
hopefully have a large patch series to refactor all of this soon.

Christian König b3c85a0fb2 drm/amdgpu: fix fundamental suspend/resume issue
Reinitializing the VM manager during suspend/resume is a very very bad
idea since all the VMs are still active and kicking.

This can lead to random VM faults after resume when new processes
become the same client ID assigned.

Chris Wilson 2e0bb5b38f drm/i915/selftests: Silence compiler warning in igt_ctx_exec
The compiler doesn't always spot the guard that object is allocated on
the first pass, leading to:

drivers/gpu/drm/i915/selftests/i915_gem_context.c: warning: 'obj' may be used uninitialized in this function [-Wuninitialized]:  => 370:8

v2: Make it more obvious by setting obj to NULL on the first pass and
any later pass where we need to reallocate.

With LVDS we were incorrectly picking the pre-programmed mode instead of
the prefered mode provided by VBT. Make sure we pick the VBT mode if
one is provided. It is likely that the mode read-out code is still wrong
but this patch fixes the immediate problem on most machines.

Daniel Vetter f928543404 drm: Fix deadlock retry loop in page_flip_ioctl
I failed to properly onion-wrap the unwind code: We acquire the vblank
reference before we start with the wait-wound locking dance, hence we
must make sure we retry before we drop the reference. Oops.

v2: The vblank_put must be after the frambuffer_put (Michel). I suck at
unwrapping code that doesn't use separate labels for each stage, but
checks each pointer first ... While re-reading everything I also
realized that we must clean up the fb refcounts, and specifically
plane->old_fb before we drop the locks, either in the final unlocking,
or in the w/w retry path. Hence the correct fix is to drop the
vblank_put to the very bottom.

Chuanxiao Dong 46cd902f6d drm/i915: set initialised only when init_context callback is NULL
During execlist_context_deferred_alloc() we presumed that the context is
uninitialised (we only just allocated the state object for it!) and
chose to optimise away the later call to engine->init_context() if
engine->init_context were NULL. This breaks with GVT's contexts that are
marked as pre-initialised to avoid us annoyingly calling
engine->init_context(). The fix is to not override ce->initialised if it
is already true.
