drm/lima: fix lima_gem_wait() return value

2019-09-10T02:09:00Z

drm_gem_reservation_object_wait() returns 0 if it succeeds and -ETIME if it timeouts, but lima driver assumed that 0 is error.

drm/lima: add timeout to drm scheduler init

2019-05-21T12:47:36Z

After "5918045c4ed4 drm/scheduler: rework job destruction", lima started to leak memory due to buffers not being destroyed after job execution in the drm scheduler. This started happening because the drm scheduler only destroyed buffers after cancelling the job timeout handler, and for lima this handler was never started as lima specified a MAX_SCHEDULE_TIMEOUT timeout. Lima seems to run well in its current state with a real timeout, so to make it more aligned with the other drivers from now on, let's use a real default timeout. This also fixes the observed memory leaks. The 500ms value was chosen as it is the current value for all other embedded gpu drivers using drm sched.

drm/scheduler: rework job destruction

2019-05-02T20:45:48Z

We now destroy finished jobs from the worker thread to make sure that we never destroy a job currently in timeout processing. By this we avoid holding lock around ring mirror list in drm_sched_stop which should solve a deadlock reported by a user. v2: Remove unused variable. v4: Move guilty job free into sched code. v5: Move sched->hw_rq_count to drm_sched_start to account for counter decrement in drm_sched_stop even when we don't call resubmit jobs if guily job did signal. v6: remove unused variable Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109692 Acked-by: Chunming Zhou Signed-off-by: Christian König Signed-off-by: Andrey Grodzovsky Signed-off-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/1555599624-12285-3-git-send-email-andrey.grodzovsky@amd.com

drm/lima: handle shared irq case for lima_pp_bcast_irq_handler

2019-04-20T08:14:09Z

On Hikey board all lima ip blocks are shared with one irq. This patch avoids a NULL ptr deref crash on this platform on startup. Tested with Weston and kmscube.
