Reduce the dependencies on drm_eld.h. Some files might be able to drop
the dependency on drm_edid.h too with the direct inclusion of drm_eld.h.

Both the drm_buddy and drm_mm tests have been converted from selftest to
kunit recently.
However, a significant portion of them are trying to exert some part of
their API over a huge number of iterations and with random variations of
their parameters. They are thus more a way to discover new bugs than
actual unit tests.
This is fine in itself but leads to very slow runtime (up to 25s for
some drm_test_mm_reserve and drm_test_mm_insert on a Ryzen 7950x while
running the tests in qemu) which make them a poor fit for kunit.
Let's remove those tests from the drm_mm and drm_buddy test suites for
now, and if it's ever needed we can always create proper unit tests for
them later on.
This made the entire DRM tests execution time (as of v6.6-rc1) come from
65s to less than .5s on a Ryzen 7950x system when running under qemu,
and from 9 minutes to about 4s on a RaspberryPi4.

Don't call drm_sched_select_entity() in drm_sched_run_job_queue(). In fact,
rename __drm_sched_run_job_queue() to just drm_sched_run_job_queue(), and let
it do just that, schedule the work item for execution.
The problem is that drm_sched_run_job_queue() calls drm_sched_select_entity()
to determine if the scheduler has an entity ready in one of its run-queues,
and in the case of the Round-Robin (RR) scheduling, the function
drm_sched_rq_select_entity_rr() does just that, selects the _next_ entity
which is ready, sets up the run-queue and completion and returns that
entity. The FIFO scheduling algorithm is unaffected.
Now, since drm_sched_run_job_work() also calls drm_sched_select_entity(), then
in the case of RR scheduling, that would result in drm_sched_select_entity()
having been called twice, which may result in skipping a ready entity if more
than one entity is ready. This commit fixes this by eliminating the call to
drm_sched_select_entity() from drm_sched_run_job_queue(), and leaves it only
in drm_sched_run_job_work().

The previous patch exposed the accumulated amount of active time per
client for each V3D queue. But this doesn't provide a global notion of
the GPU usage.
Therefore, provide the accumulated amount of active time for each V3D
queue (BIN, RENDER, CSD, TFU and CACHE_CLEAN), considering all the jobs
submitted to the queue, independent of the client.
This data is exposed through the sysfs interface, so that if the
interface is queried at two different points of time the usage percentage
of each of the queues can be calculated.

This patch exposes the accumulated amount of active time per client
through the fdinfo infrastructure. The amount of active time is exposed
for each V3D queue: BIN, RENDER, CSD, TFU and CACHE_CLEAN.
In order to calculate the amount of active time per client, a CPU clock
is used through the function local_clock(). The point where the jobs has
started is marked and is finally compared with the time that the job had
finished.
Moreover, the number of jobs submitted to each queue is also exposed on
fdinfo through the identifier "v3d-jobs-<queue>".

It is better not to lose precision and not revert to 1 MiB size
granularity for every size greater than 1 MiB.
Sizes in KiB should not be so troublesome to read (and in fact machine
parsing is I expect the norm here), they align with other api like
/proc/meminfo, and they allow writing tests for the interface without
having to embed drm.ko implementation knowledge into them. (Like knowing
that minimum buffer size one can use for successful verification has to be
1MiB aligned, and on top account for any pre-existing memory utilisation
outside of driver's control.)
But probably even more importantly I think that it is just better to show
the accurate sizes and not arbitrary lose precision for a little bit of a
stretched use case of eyeballing fdinfo text directly.

Because a) helper is exported to other parts of the scheduler and
b) there isn't a plain drm_sched_wakeup to begin with, I think we can
drop the suffix and by doing so separate the intimiate knowledge
between the scheduler components a bit better.

"If ready" is not immediately clear what it means - is the scheduler
ready or something else? Drop the suffix, clarify kerneldoc, and employ
the same naming scheme as in drm_sched_run_free_queue:
- drm_sched_run_job_queue - enqueues if there is something to enqueue
*and* scheduler is ready (can queue)
- __drm_sched_run_job_queue - low-level helper to simply queue the job

The current name makes it sound like helper will free a queue, while what
it does is it enqueues the free job worker.
Rename it to drm_sched_run_free_queue to align with existing
drm_sched_run_job_queue.
Despite that creating an illusion there are two queues, while in reality
there is only one, at least it creates a consistent naming for the two
enqueuing helpers.
At the same time simplify the "if done" helper by dropping the suffix and
adding a double underscore prefix to the one which just enqueues.

Whether or not there are more jobs to clean up does not depend on the
existance of the current job, given both drm_sched_get_finished_job and
drm_sched_free_job_queue_if_done take and drop the job list lock.
Therefore it is confusing to make it read like there is a dependency.

"Get cleanup job" makes it sound like helper is returning a job which will
execute some cleanup, or something, while the kerneldoc itself accurately
says "fetch the next _finished_ job". So lets rename the helper to be self

In Xe, the new Intel GPU driver, a choice has made to have a 1 to 1
mapping between a drm_gpu_scheduler and drm_sched_entity. At first this
seems a bit odd but let us explain the reasoning below.
1. In Xe the submission order from multiple drm_sched_entity is not
guaranteed to be the same completion even if targeting the same hardware
engine. This is because in Xe we have a firmware scheduler, the GuC,
which allowed to reorder, timeslice, and preempt submissions. If a using
shared drm_gpu_scheduler across multiple drm_sched_entity, the TDR falls
apart as the TDR expects submission order == completion order. Using a
dedicated drm_gpu_scheduler per drm_sched_entity solve this problem.
2. In Xe submissions are done via programming a ring buffer (circular
buffer), a drm_gpu_scheduler provides a limit on number of jobs, if the
limit of number jobs is set to RING_SIZE / MAX_SIZE_PER_JOB we get flow
control on the ring for free.
A problem with this design is currently a drm_gpu_scheduler uses a
kthread for submission / job cleanup. This doesn't scale if a large
number of drm_gpu_scheduler are used. To work around the scaling issue,
use a worker rather than kthread for submission / job cleanup.
v2:
- (Rob Clark) Fix msm build
- Pass in run work queue
v3:
- (Boris) don't have loop in worker
v4:
- (Tvrtko) break out submit ready, stop, start helpers into own patch

When a fence signals there is a very small race window where the timestamp
isn't updated yet. sync_file solves this by busy waiting for the
timestamp to appear, but on other ocassions didn't handled this
correctly.
Provide a dma_fence_timestamp() helper function for this and use it in
all appropriate cases.
Another alternative would be to grab the spinlock when that happens.
v2 by teddy: add a wait parameter to wait for the timestamp to show up, in case
the accurate timestamp is needed and/or the timestamp is not based on
ktime (e.g. hw timestamp)

This reverts commit 4d56a4f08391857ba93465de489707b66adad114.
The DMA-fence annotations cause a lockdep warning (see below). As per
https://patchwork.freedesktop.org/patch/462170/ it sounds like the
annotations don't work correctly.

sg_page_iter_page() doesn't return an error code, so the IS_ERR() check
is wrong and the error path will never be executed. This also allows
simplifying the code to remove the local variable 'page'.

This is already uAPI, xserver parses it. It's useful to document
since user-space might want to lookup the parent connector.
Additionally, people (me included) have misunderstood the PATH
property for being stable across reboots, but since a KMS object
ID is baked in there that's not the case. So PATH shouldn't be
used as-is in config files and such.

This new IOCTL allows callers to close a framebuffer without
disabling planes or CRTCs. This takes inspiration from Rob Clark's
unref_fb IOCTL [1] and DRM_MODE_FB_PERSIST [2].
User-space patch for wlroots available at [3]. IGT test available
at [4].
v2: add an extra pad field just in case we want to extend this IOCTL
in the future (Pekka, Sima).

drm_mode_rmfb performs two operations: drop the FB from the
file_priv->fbs list, and make sure the FB is no longer used on a
plane.
In the next commit an IOCTL which only does so former will be
introduced, so let's split it into a separate function.
No functional change, only refactoring.
v2: no change

Signed-off-by: Luben Tuikov <ltuikov89@gmail.com>

The GPU scheduler has now a variable number of run-queues, which are set up at
drm_sched_init() time. This way, each driver announces how many run-queues it
requires (supports) per each GPU scheduler it creates. Note, that run-queues
correspond to scheduler "priorities", thus if the number of run-queues is set
to 1 at drm_sched_init(), then that scheduler supports a single run-queue,
i.e. single "priority". If a driver further sets a single entity per
run-queue, then this creates a 1-to-1 correspondence between a scheduler and
a scheduled entity.

The Collabora Lava farm added a tag called `subset-1-gfx` to half of
devices the graphics community use.
Lets use this tag so we don't occupy all the resources.
This is particular important because Mesa3D shares the resources with
DRM-CI and use them to do pre-merge tests, so it can block developers
from getting their patches merged.

Add helper script that given a gitlab pipeline url, analyse which are
the failures and flakes and update the xfails folder accordingly.
Example:
Trigger a pipeline in gitlab infrastructure, than re-try a few jobs more
than once (so we can have data if failures are consistent across jobs
with the same name or if they are flakes) and execute:
update-xfails.py https://gitlab.freedesktop.org/helen.fornazier/linux/-/pipelines/970661
git diff should show you that it updated files in xfails folder.

In case of the merge requests it might be useful to push repo-specific
fixes which have not yet propagated to the -external-fixes branch in the
main UPSTREAM_REPO. For example, in case of drm/msm development, we are
staging fixes locally for testing, before pushing them to the drm/drm
repo. Thus, if the CI run was triggered by merge request, also pick up
the -external fixes basing on the the CI_MERGE target repo / and branch.

Add support for displaying 10-bit 4:2:0 and 4:2:2 formats produced by
the Rockchip Video Decoder on RK322X, RK3288, RK3328 and RK3399.
Also add support for 10-bit 4:4:4 format while at it.
V5: Use drm_format_info_min_pitch() for correct bpp
Add missing NV21, NV61 and NV42 formats
V4: Rework RK3328/RK3399 win0/1 data to not affect RK3368
V2: Added NV30 support

DRM_FORMAT_NV20 and DRM_FORMAT_NV30 formats is the 2x1 and non-subsampled
variant of NV15, a 10-bit 2-plane YUV format that has no padding between
components. Instead, luminance and chrominance samples are grouped into 4s
so that each group is packed into an integer number of bytes:
YYYY = UVUV = 4 * 10 bits = 40 bits = 5 bytes
The '20' and '30' suffix refers to the optimum effective bits per pixel
which is achieved when the total number of luminance samples is a multiple
of 4.
V2: Added NV30 format

formats_win_full_10bit is for cluster window,
formats_win_full_10bit_yuyv is for rk356x esmart, rk3588 esmart window
will support more format.
formats_win_lite is for smart window.
Rename it based the windows type may let meaning is clearer

The cluster window on vop2 doesn't support linear yuv
format(NV12/16/24), it only support afbc based yuv
format(DRM_FORMAT_YUV420_8BIT/10BIT), which will be
added in next patch.

We can't rely on cpp for bpp calculation as the cpp of
some formats(DRM_FORMAT_YUV420_8BIT/10BIT, etc) is zero.
