fc94d32dbf drm/radeon: drop confusing message about backlight control
The message is harmless and confusing.  On PX systems,
there is one ATIF method, but potentially multiple GPUs
leading to an error on the GPU with no backlight control.

23a1a9e54e drm/amdgpu: Disable RPM helpers while reprobing connectors on resume
Just about all of amdgpu's connector probing functions try to acquire
runtime PM refs. If we try to do this in the context of
amdgpu_resume_kms by calling drm_helper_hpd_irq_event(), we end up
deadlocking the system.

Since we're guaranteed to be holding the spinlock for RPM in
amdgpu_resume_kms, and we already know the GPU is in working order, we
need to prevent the RPM helpers from trying to run during the initial
connector reprobe on resume.

There's a couple of solutions I've explored for fixing this, but this
one by far seems to be the simplest and most reliable (plus I'm pretty
sure that's what disable_depth is there for anyway).

Reproduction recipe:
  - Get any laptop dual GPUs using PRIME
  - Make sure runtime PM is enabled for amdgpu
  - Boot the machine
  - If the machine managed to boot without hanging, switch out of X to
    another VT. This should definitely cause X to hang infinitely.

Changes since v1:
  - add appropriate #ifdef checks for CONFIG_PM. This is not very
    useful, but it appears some kernel test suites test compiling amdgpu
    with CONFIG_PM disabled, which results in this patch breaking the builds
    if we don't include this #ifdef

6ce213575c drm/i915: Add missing ring_mask to Pineview
It appears that we never told Pineview it has a RENDER_RING. This was
all fine until we started using the ring_mask for determining all the
available rings to initialise for legacy ringbuffer submission in commit
88d2ba2e95 ("drm/i915: Unify engine init loop"). Though really it is a
latent bug since the ring_mask inception in commit 73ae478cdf
("drm/i915: Replace has_bsd/blt/vebox with a mask").

To prevent similar mishaps in future, add a WARN_ON() if we find
ourselves with a device without any rings.

a1f5524a66 drm: aux ->transfer() can return 0, deal with it
Restore the correct behaviour (as in check msg.reply) when aux
->transfer() returns 0. It got removed in
commit 82922da391 ("drm/dp_helper: Retry aux transactions on all errors")

Now I can actually dump the "entire" DPCD on a Dell UP2314Q with
ddrescue. It has some offsets in the DPCD that can't be read
for some resaon, all you get is defers. Previously ddrescue would
just give up at the first unredable offset on account of
read() returning 0 means EOF. Here's the ddrescue log

12c100bfa5 drm/i915: Never fully mask the the EI up rps interrupt on SNB/IVB
SNB (and IVB too I suppose) starts to misbehave if the GPU gets stuck
in an infinite batch buffer loop. The GPU apparently hogs something
critical and CPUs start to lose interrupts and whatnot. We can keep
the system limping along by unmasking some interrupts in
GEN6_PMINTRMSK. The EI up interrupt has been previously chosen for
that task, so let's never mask it.

Since 0b52297f22 ("reset: Add support for shared reset controls") the
new Reset API now demands consumers choose either an *_exclusive or a

This issue was found when running a kernel containing the aforementioned

more used reset lines are in fact shared.  This is why we're using the
*_shared variant.

This is also blocking a platform milestone so let's disable
this for now while we make sure we don't have any more loading
issue, or related basic hangs and it pass BAT for real in all
platofmrs.

In case BAT is wrong let's first fix BAT before re-enable it here.

1542f5d90a drm/i915/bxt: Fix inadvertent CPU snooping due to incorrect MOCS config
Setting a write-back cache policy in the MOCS entry definition also
implies snooping, which has a considerable overhead. This is
unexpected for a few reasons:
- From user-space's point of view since it didn't want a coherent
  surface (it didn't set the buffer as such via the set caching IOCTL).
- There is a separate MOCS entry field for snooping (which we never
  set).
- This MOCS table is about caching in (e)LLC and there is no (e)LLC on
  BXT. There is a separate table for L3 cache control.

Considering the above the current behavior of snooping looks like an
unintentional side-effect of the WB setting. Changing it to be LLC-UC
gets rid of the snooping without any ill-effects. For a coherent
surface the application would use a separate MOCS entry at index 1 and
call the set caching IOCTL to setup the PTE entries for the
corresponding buffer to be snooped. In the future we could also add a
new MOCS entry for coherent surfaces.

This resulted in 70% improvement in synthetic texturing benchmarks.

Kudos to Valtteri Rantala, Eero Tamminen and Michael T Frederick and
Ville who helped to narrow the source of problem to the kernel and to
the snooping behaviour in particular.

With a follow-up change to adjust the 3rd entry value
igt/gem_mocs_settings is passing after this change.

v2:
- Rebase on v2 of patch 1/2.
v3:
- Set the entry as LLC uncached instead of PTE-passthrough. This way
  we also keep snooping disabled, but we also make the cacheability/
  coherency setting indepent of the PTE which is managed by the
  kernel. (Chris)

f527a38ee7 drm/i915: Update the breadcrumb interrupt counter before enabling
In order to close a race with a long running hangcheck comparing a stale
interrupt counter with a just started waiter, we need to first bump the
counter as we start the fresh wait.

2529d57050 drm/i915: Drop racy markup of missed-irqs from idle-worker
During the idle-worker we disable the hangcheck and so kick any waiters
that should have been completed (since the GPU is now idle). Unlike the
hangcheck, we do not take any care to avoid the race between the irq
handler and ourselves, and so it is possible for us to declare a missed
interrupt even as the bottom-half is being scheduled to run. Let's
ignore this race to stop a potential false-positive error.
