drm/vc4: plane: Add support for DRM_FORMAT_P030
The P030 format, used with the DRM_FORMAT_MOD_BROADCOM_SAND128 modifier,
is a format output by the video decoder on the BCM2711.

Add native support to the KMS planes for that format.

Matthew Brost 0013f5f5c0 drm/i915/guc: Selftest for stealing of guc ids
Testing the stealing of guc ids is hard from user space as we have 64k
guc_ids. Add a selftest, which artificially reduces the number of guc
ids, and forces a steal.

The test creates a spinner which is used to block all subsequent
submissions until it completes. Next, a loop creates a context and a NOP
request each iteration until the guc_ids are exhausted (request creation
returns -EAGAIN). The spinner is ended, unblocking all requests created
in the loop. At this point all guc_ids are exhausted but are available
to steal. Try to create another request which should successfully steal
a guc_id. Wait on last request to complete, idle GPU, verify a guc_id
was stolen via a counter, and exit the test. Test also artificially
reduces the number of guc_ids so the test runs in a timely manner.

John Harrison 2406846ec4 drm/i915/guc: Don't hog IRQs when destroying contexts
While attempting to debug a CT deadlock issue in various CI failures
(most easily reproduced with gem_ctx_create/basic-files), I was seeing
CPU deadlock errors being reported. This were because the context
destroy loop was blocking waiting on H2G space from inside an IRQ
spinlock. There no was deadlock as such, it's just that the H2G queue
was full of context destroy commands and GuC was taking a long time to
process them. However, the kernel was seeing the large amount of time
spent inside the IRQ lock as a dead CPU. Various Bad Things(tm) would
then happen (heartbeat failures, CT deadlock errors, outstanding H2G
WARNs, etc.).

Re-working the loop to only acquire the spinlock around the list
management (which is all it is meant to protect) rather than the
entire destroy operation seems to fix all the above issues.

Maxime Ripard 244a36e50d drm/vc4: kms: Wait for the commit before increasing our clock rate
Several DRM/KMS atomic commits can run in parallel if they affect
different CRTC. These commits share the global HVS state, so we have
some code to make sure we run commits in sequence. This synchronization
code is one of the first thing that runs in vc4_atomic_commit_tail().

Another constraints we have is that we need to make sure the HVS clock
gets a boost during the commit. That code relies on clk_set_min_rate and
will remove the old minimum and set a new one. We also need another,
temporary, minimum for the duration of the commit.

The algorithm is thus to set a temporary minimum, drop the previous
one, do the commit, and finally set the minimum for the current mode.

However, the part that sets the temporary minimum and drops the older
one runs before the commit synchronization code.

Thus, under the proper conditions, we can end up mixing up the minimums
and ending up with the wrong one for our current step.

To avoid it, let's move the clock setup in the protected section.

Nicholas Kazlauskas 47e62dbd8d drm/amd/display: Reset DMCUB before HW init
[Why]
If the firmware wasn't reset by PSP or HW and is currently running
then the firmware will hang or perform underfined behavior when we
modify its firmware state underneath it.

[How]
Reset DMCUB before setting up cache windows and performing HW init.

Nicholas Kazlauskas 0215466a85 drm/amd/display: Set exit_optimized_pwr_state for DCN31
[Why]
SMU now respects the PHY refclk disable request from driver.

This causes a hang during hotplug when PHY refclk was disabled
because it's not being re-enabled and the transmitter control
starts on dc_link_detect.

[How]
We normally would re-enable the clk with exit_optimized_pwr_state
but this is only set on DCN21 and DCN301. Set it for dcn31 as well.

This fixes DMCUB timeouts in the PHY.

Matthew Auld 1b9e8b1feb drm/i915/debugfs: add noreclaim annotations
We have a debugfs hook to directly call into i915_gem_shrink() with the
fs_reclaim acquire annotations to simulate hitting direct reclaim.
However we should also annotate this with memalloc_noreclaim, which will
set PF_MEMALLOC for us on the current context, to ensure we can't
re-enter direct reclaim(just like "real" direct reclaim does). This is
an issue now that ttm_bo_validate could potentially be called here,
which might try to allocate a tiny amount of memory to hold the new
ttm_resource struct, as per the below splat:

Simon Ser 43d5ac7d07 drm: document DRM_IOCTL_MODE_GETFB2
There are a few details specific to the GETFB2 IOCTL.

It's not immediately clear how user-space should check for the
number of planes. Suggest using the handles field or the pitches
field.

The modifier array is filled with zeroes, ie. DRM_FORMAT_MOD_LINEAR.
So explicitly tell user-space to not look at it unless the flag is
set.

Changes in v2 (Daniel):
- Mention that handles should be used to compute the number of planes,
  and only refer to pitches as a fallback.
- Reword bit about undefined modifier.

This extends the previous sanitychecking of device memory to read/write
all the memory on the device during the device probe, ala memtest86,
as an optional module parameter: i915.memtest=1. This is not expected to
be fast, but a reasonably thorough verfification that the device memory
is accessible and doesn't return bit errors.
