drm/msm: Add missing check and destroy for alloc_ordered_workqueue

2023-01-18T01:25:18+00:00

Add check for the return value of alloc_ordered_workqueue as it may return NULL pointer. Moreover, use the destroy_workqueue in the later fails in order to avoid memory leak.

drm/msm: Add MSM_SUBMIT_BO_NO_IMPLICIT

2023-01-16T18:33:57+00:00

In cases where implicit sync is used, it is still useful (for things like sub-allocation, etc) to allow userspace to opt-out of implicit sync on per-BO basis.

drm/msm: clean event_thread->worker in case of an error

2023-01-09T20:54:42+00:00

If worker creation fails, nullify the event_thread->worker, so that msm_drm_uninit() doesn't try accessing invalid memory location. While we are at it, remove duplicate assignment to the ret variable.

drm/msm: Hangcheck progress detection

2022-11-17T18:39:12+00:00

If the hangcheck timer expires, check if the fw's position in the cmdstream has advanced (changed) since last timer expiration, and allow it up to three additional "extensions" to it's alotted time. The intention is to continue to catch "shader stuck in a loop" type hangs quickly, but allow more time for things that are actually making forward progress. Because we need to sample the CP state twice to detect if there has not been progress, this also cuts the the timer's duration in half. v2: Fix typo (REG_A6XX_CP_CSQ_IB2_STAT), add comment v3: Only halve hangcheck timer duration for generations which support progress detection (hdanton); removed unused a5xx progress (without knowing how to adjust for data buffered in ROQ it is too likely to report a false negative) v4: Comment updates to better describe the total hangcheck duration when progress detection is applied Reviewed-by: Chia-I Wu Tested-by: Chia-I Wu # dEQP-GLES2.functional.flush_finish.wait Signed-off-by: Rob Clark Reviewed-by: Akhil P Oommen Patchwork: https://patchwork.freedesktop.org/patch/511584/ Link: https://lore.kernel.org/r/20221114193049.1533391-3-robdclark@gmail.com
