Each hardware CRTC has a single flip work queue.
When a radeon_flip_work_func item is queued, it needs to be executed
ASAP because even a slight delay may cause the flip to be delayed by
one refresh cycle.
Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here
since a delay can cause the outcome to miss the refresh cycle.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary here.

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.
Bug: https://bugzilla.kernel.org/show_bug.cgi?id=115011 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Hans de Goede <jwrdegoede@fedoraproject.org>
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

The code in imx_ldb_encoder_mode_set crashes with a NULL pointer

cleared by drm_atomic_helper_swap_state:
Instead of trying to walk only the connectors in atomic state to which we

current encoder and containing a bus_format description.

drm/sti: use new Reset API
Since 0b52297f228 ("reset: Add support for shared reset controls") the
new Reset API now demands consumers choose either an *_exclusive or a
*_shared line when requesting reset lines.
This issue was found when running a kernel containing the aforementioned
patch which includes an informitive WARN(). It implies that one or
more used reset lines are in fact shared. This is why we're using the
*_shared variant.
We have latency issues that might impact the performance: #96606.
and hangs and loading issues on resume after S4: #96526.
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.

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)

v4.7-rc6.
In 4.7-rc1 we introduced auto-probing for the ACPI DSM (device-
specific-method) format that the platform firmware implements for
nvdimm devices. We initially fixed a regression in probing the QEMU
DSM implementation by making acpi_check_dsm() tolerant of the way QEMU
reports the "0 DSMs supported" condition.
However, that broke HPE platforms since that tolerance caused the
driver to mistakenly match the 1-zero-byte response those platforms
give to "unknown" commands. Instead, we simply make the driver
tolerant of not finding any supported DSMs. This has been tested to
work with both QEMU and HPE platforms.
This commit has appeared in a -next release with no reported issues"
