Subject: [PATCH] drm/rockchip: Convert to drm_gem_object_funcs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in rockchip. The only exception is gem_prime_mmap,
which is non-trivial to convert.
v3:
* update documentation

The only usage of dw_hdmi_i2s_ops is to assign its address to the ops
field in the hdmi_codec_pdata struct, which is a const pointer. Make it
const to allow the compiler to put it in read-only memory.

Subject: [PATCH] drm/panfrost: Fix job timeout handling
If more than two jobs end up timeout-ing concurrently, only one of them
(the one attached to the scheduler acquiring the lock) is fully handled.
The other one remains in a dangling state where it's no longer part of
the scheduling queue, but still blocks something in scheduler, leading
to repetitive timeouts when new jobs are queued.
Let's make sure all bad jobs are properly handled by the thread
acquiring the lock.
v3:
- Add Steven's R-b
- Don't take the sched_lock when stopping the schedulers
v2:
- Fix the subject prefix
- Stop the scheduler before returning from panfrost_job_timedout()
- Call cancel_delayed_work_sync() after drm_sched_stop() to make sure
no timeout handlers are in flight when we reset the GPU (Steven Price)
- Make sure we release the reset lock before restarting the
schedulers (Steven Price)
