Vladimir Lypak 9bcf5687fe drm/msm/a5xx: fix races in preemption evaluation stage ... [ Upstream commit ce050f307ad93bcc5958d0dd35fc276fd394d274 ] On A5XX GPUs when preemption is used it's invietable to enter a soft lock-up state in which GPU is stuck at empty ring-buffer doing nothing. This appears as full UI lockup and not detected as GPU hang (because it's not). This happens due to not triggering preemption when it was needed. Sometimes this state can be recovered by some new submit but generally it won't happen because applications are waiting for old submits to retire. One of the reasons why this happens is a race between a5xx_submit and a5xx_preempt_trigger called from IRQ during submit retire. Former thread updates ring->cur of previously empty and not current ring right after latter checks it for emptiness. Then both threads can just exit because for first one preempt_state wasn't NONE yet and for second one all rings appeared to be empty. To prevent such situations from happening we need to establish guarantee for preempt_trigger to make decision after each submit or retire. To implement this we serialize preemption initiation using spinlock. If switch is already in progress we need to re-trigger preemption when it finishes.
