Subject: drm/sched: Avoid memory leaks with cancel_job() callback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since its inception, the GPU scheduler can leak memory if the driver
calls drm_sched_fini() while there are still jobs in flight.

The simplest way to solve this in a backwards compatible manner is by
adding a new callback, drm_sched_backend_ops.cancel_job(), which
instructs the driver to signal the hardware fence associated with the
job. Afterwards, the scheduler can safely use the established free_job()
callback for freeing the job.

Implement the new backend_ops callback cancel_job().

Subject: drm/sched/tests: Implement cancel_job() callback

The GPU Scheduler now supports a new callback, cancel_job(), which lets
the scheduler cancel all jobs which might not yet be freed when
drm_sched_fini() runs. Using this callback allows for significantly
simplifying the mock scheduler teardown code.

Implement the cancel_job() callback and adjust the code where necessary.

Subject: drm/sched/tests: Add unit test for cancel_job()

The scheduler unit tests now provide a new callback, cancel_job(). This
callback gets used by drm_sched_fini() for all still pending jobs to
cancel them.

Implement a new unit test to test this.

Subject: drm/nouveau: Make fence container helper usable driver-wide

In order to implement a new DRM GPU scheduler callback in Nouveau, a
helper for obtaining a nouveau_fence from a dma_fence is necessary. Such
a helper exists already inside nouveau_fence.c, called from_fence().

Make that helper available to other C files with a more precise name.

Subject: drm/nouveau: Remove waitque for sched teardown

struct nouveau_sched contains a waitque needed to prevent
drm_sched_fini() from being called while there are still jobs pending.
Doing so so far would have caused memory leaks.

With the new memleak-free mode of operation switched on in
drm_sched_fini() by providing the callback nouveau_sched_cancel_job()
the waitque is not necessary anymore.

Remove the waitque.

When hibernate with data center dGPUs, huge number of VRAM BOs evicted
to GTT and takes too much system memory. This will cause hibernation
fail due to insufficient memory for creating the hibernation image.

Move GTT BOs to shmem in KMD, then shmem to swap disk in kernel
hibernation code to make room for hibernation image.

Subject: PM: hibernate: add new api pm_hibernate_is_recovering()

dev_pm_ops.thaw() is called in following cases:
* normal case: after hibernation image has been created.
* error case 1: creation of a hibernation image has failed.
* error case 2: restoration from a hibernation image has failed.

For normal case, it is called mainly for resume storage devices for
saving the hibernation image. Other devices that are not involved
in the image saving do not need to resume the device. But since there's
no api to know which case thaw() is called, device drivers can't
conditionally resume device in thaw().

The new pm_hibernate_is_recovering() is such a api to query if thaw() is
called in normal case.

Subject: drm/amdgpu: do not resume device in thaw for normal hibernation

For normal hibernation, GPU do not need to be resumed in thaw since it is
not involved in writing the hibernation image. Skip resume in this case
can reduce the hibernation time.

On VM with 8 * 192GB VRAM dGPUs, 98% VRAM usage and 1.7TB system memory,
this can save 50 minutes.

Subject: drm/amdgpu: Fix lifetime of struct amdgpu_task_info after ring reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a ring reset happens, amdgpu calls drm_dev_wedged_event() using
struct amdgpu_task_info *ti as one of the arguments. After using *ti, a
call to amdgpu_vm_put_task_info(ti) is required to correctly track its
lifetime.

However, it's called from a place that the ring reset path never reaches
due to a goto after drm_dev_wedged_event() is called. Move
amdgpu_vm_put_task_info() bellow the exit label to make sure that it's
called regardless of the code path.

amdgpu_vm_put_task_info() can only accept a valid address or NULL as
argument, so initialise *ti to make sure we can call this function if
*ti isn't used.

Subject: drm/bridge: Pass down connector to drm bridge detect hook

In some application scenarios, we hope to get the corresponding
connector when the bridge's detect hook is invoked.

In most cases, we can get the connector by drm_atomic_get_connector_for_encoder
if the encoder attached to the bridge is enabled, however there will
still be some scenarios where the detect hook of the bridge is called
but the corresponding encoder has not been enabled yet. For instance,
this occurs when the device is hot plug in for the first time.

Since the call to bridge's detect is initiated by the connector, passing
down the corresponding connector directly will make things simpler.

Commit ec62d37d2c0d("drm/panthor: Fix the fast-reset logic") did away
with the only reference to panthor_vm_flush_all(), so let's get rid
of the orphaned definition.

Subject: drm/panel-edp: Add BOE NE14QDM panel for Dell Latitude 7455

Cannot confirm which variant exactly it is, as the EDID alphanumeric data
contains '0RGNR' <0x80> 'NE14QDM' and ends there; but it's 60 Hz and with
touch.

I do not have access to datasheets for these panels, so the timing is
a guess that was tested to work fine on this laptop.

Raw EDID dump:

Subject: drm/sched: Rename DRM_GPU_SCHED_STAT_NOMINAL to
 DRM_GPU_SCHED_STAT_RESET
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Among the scheduler's statuses, the only one that indicates an error is
DRM_GPU_SCHED_STAT_ENODEV. Any status other than DRM_GPU_SCHED_STAT_ENODEV
signifies that the operation succeeded and the GPU is in a nominal state.

However, to provide more information about the GPU's status, it is needed
to convey more information than just "OK".

Therefore, rename DRM_GPU_SCHED_STAT_NOMINAL to
DRM_GPU_SCHED_STAT_RESET, which better communicates the meaning of this
status. The status DRM_GPU_SCHED_STAT_RESET indicates that the GPU has
hung, but it has been successfully reset and is now in a nominal state
again.

Subject: drm/sched: Allow drivers to skip the reset and keep on running
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the DRM scheduler times out, it's possible that the GPU isn't hung;
instead, a job just took unusually long (longer than the timeout) but is
still running, and there is, thus, no reason to reset the hardware. This
can occur in two scenarios:

  1. The job is taking longer than the timeout, but the driver determined
     through a GPU-specific mechanism that the hardware is still making
     progress. Hence, the driver would like the scheduler to skip the
     timeout and treat the job as still pending from then onward. This
     happens in v3d, Etnaviv, and Xe.
  2. Timeout has fired before the free-job worker. Consequently, the
     scheduler calls `sched->ops->timedout_job()` for a job that isn't
     timed out.

These two scenarios are problematic because the job was removed from the
`sched->pending_list` before calling `sched->ops->timedout_job()`, which
means that when the job finishes, it won't be freed by the scheduler
though `sched->ops->free_job()` - leading to a memory leak.

To solve these problems, create a new `drm_gpu_sched_stat`, called
DRM_GPU_SCHED_STAT_NO_HANG, which allows a driver to skip the reset. The
new status will indicate that the job must be reinserted into
`sched->pending_list`, and the hardware / driver will still complete that
job.

As more KUnit tests are introduced to evaluate the basic capabilities of
the `timedout_job()` hook, the test suite will continue to increase in
duration. To reduce the overall running time of the test suite, decrease
the scheduler's timeout for the timeout tests.

Subject: drm/v3d: Use DRM_GPU_SCHED_STAT_NO_HANG to skip the reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a CL/CSD job times out, we check if the GPU has made any progress
since the last timeout. If so, instead of resetting the hardware, we skip
the reset and allow the timer to be rearmed. This gives long-running jobs
a chance to complete.

Instead of manipulating scheduler's internals, inform the scheduler that
the job did not actually timeout and no reset was performed through
the new status code DRM_GPU_SCHED_STAT_NO_HANG.

Subject: drm/etnaviv: Use DRM_GPU_SCHED_STAT_NO_HANG to skip the reset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Etnaviv can skip a hardware reset in two situations:

  1. TDR has fired before the free-job worker and the timeout is spurious.
  2. The GPU is still making progress on the front-end and we can give
     the job a chance to complete.

Instead of manipulating scheduler's internals, inform the scheduler that
the job did not actually timeout and no reset was performed through
the new status code DRM_GPU_SCHED_STAT_NO_HANG.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Xe can skip the reset if TDR has fired before the free job worker and can
also re-arm the timeout timer in some scenarios. Instead of manipulating
scheduler's internals, inform the scheduler that the job did not actually
timeout and no reset was performed through the new status code
DRM_GPU_SCHED_STAT_NO_HANG.

Note that, in the first case, there is no need to restart submission if it
hasn't been stopped.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

Panfrost can skip the reset if TDR has fired before the free-job worker.
Currently, since Panfrost doesn't take any action on these scenarios, the
job is being leaked, considering that `free_job()` won't be called.

To avoid such leaks, inform the scheduler that the job did not actually
timeout and no reset was performed through the new status code
DRM_GPU_SCHED_STAT_NO_HANG.

The test works even without it, but lockdep starts screaming when it is

Trivially fix it by acquiring the lock before we try to allocate

The test is quite fragile since it tries to allocate halve available system
memory + 1 page.

If the system has either not enough memory to make the allocation work
with other things running in parallel or to much memory so the allocation
fails as to large/invalid the test will fail.

Completely remove the test. We already validate swapout on the device
level and that test seems to be stable.

The driver already uses the dev_err_probe() helper (that only prints error

Also do the same when it fails to obtain the reset GPIO.

Subject: drm/sitronix/st7571-i2c: Add an indirection level to parse DT

Other Sitronix display controllers might need a different parsing DT
logic, so lets add a .parse_dt callback to struct st7571_panel_data.

Subject: drm/sitronix/st7571-i2c: Add support for the ST7567 Controller

The Sitronix ST7567 is a monochrome Dot Matrix LCD Controller that has SPI,
I2C and parallel interfaces. The st7571-i2c driver only has support for I2C
so displays using other transport interfaces are currently not supported.

The DRM_FORMAT_R1 pixel format and data commands are the same than what
is used by the ST7571 controller, so only is needed a different callback
that implements the expected initialization sequence for the ST7567 chip.

Move to using the new API devm_drm_panel_alloc() to allocate the
panel. In the call to the new API, avoid using explicit type and use
__typeof() for more type safety.

Subject: drm/tests: edid: Fix monitor range limits

For some reason, some EDIDs used by kunit had Monitor Range Limits
making no sense, and not matching the edid-decode output in the comment.

While they were in the comments as:
    Display Range Limits:
      Monitor ranges (GTF): 50-70 Hz V, 30-70 kHz H, max dotclock 150 MHz

They were actually:
    Display Range Limits:
      Monitor ranges (GTF): 50-70 Hz V, 0-0 kHz H, max dotclock 1960 MHz

Fix that section of the EDIDs to match the expected edid-decode output.

Subject: drm/tests: edid: Update CTA-861 HDMI Vendor Specific Data Block

For some reason, the HDMI VSDBs in our kunit EDIDs had a length longer
than expected.

While this was harmless, we should get rid of it to make it somewhat
predictable.

Subject: drm/tests: edid: Add edid-decode --check output

Some of our EDIDs are (rightfully) invalid, but most of them should be
valid.

Let's add the edid-decode --check of these EDIDs when they were
generated, so we know what to expect going forward, and a comment to
explicitly mention when we expect them to be broken.

Subject: drm: Pass pixel_format+modifier to .get_format_info()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Decouple .get_format_info() from struct drm_mode_fb_cmd2 and just
pass the pixel format+modifier combo in by hand.

We may want to use .get_format_info() outside of the normal
addfb paths where we won't have a struct drm_mode_fb_cmd2, and
creating a temporary one just for this seems silly.

v2: Fix intel_fb_get_format_info() docs (Laurent)

Subject: drm: Look up the format info earlier
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Look up the format info already in drm_internal_framebuffer_create()
so that we can later pass it along to .fb_create(). Currently various
drivers are doing additional lookups in their .fb_create()
implementations, and these lookups are rather expensive now (given
how many different pixel formats we have).

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Pass along the format information from the top to .fb_create()
so that we can avoid redundant (and somewhat expensive) lookups
in the drivers.

Done with cocci (with some manual fixups):

Subject: drm: Allow the caller to pass in the format info to
 drm_helper_mode_fill_fb_struct()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Soon all drivers should have the format info already available in the
places where they call drm_helper_mode_fill_fb_struct(). Allow it to
be passed along into drm_helper_mode_fill_fb_struct() instead of doing
yet another redundant lookup.

Start by always passing in NULL and still doing the extra lookup.
The actual changes to avoid the lookup will follow.

Done with cocci (with some manual fixups):

Subject: drm: Make passing of format info to drm_helper_mode_fill_fb_struct()
 mandatory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that everyone passes along the format info to
drm_helper_mode_fill_fb_struct() we can make this behaviour
mandatory and drop the extra lookup.

Subject: drm/amdgpu: Fix missing unlocking in an error path in
 amdgpu_userq_create()

If kasprintf() fails, some mutex still need to be released to avoid locking
issue, as already done in all other error handling path.

Fixes: c03ea34cbf88 ("drm/amdgpu: add support of debugfs for mqd information")
