* gpu: nvgpu: gv11b: implement teardown_ch_tsg fifo opsSeema Khowala2017-04-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Context TSG teardown procedure: 1. Disable scheduling for the engine's runlist via NV_PFIFO_SCHED_DISABLE. This enables SW to determine whether a context has hung later in the process: otherwise, ongoing work on the runlist may keep ENG_STATUS from reaching a steady state. 2. Disable all channels in the TSG being torn down or submit a new runlist that does not contain the TSG. This is to prevent the TSG from being rescheduled once scheduling is reenabled in step 6. 3. Initiate a preempt of the engine by writing the bit associated with its runlist to NV_PFIFO_RUNLIST_PREEMPT. This allows to begin the preempt process prior to doing the slow register reads needed to determine whether the context has hit any interrupts or is hung. Do not poll NV_PFIFO_RUNLIST_PREEMPT for the preempt to complete. 4. Check for interrupts or hangs while waiting for the preempt to complete. During the pbdma/eng preempt finish polling, any stalling interrupts relating to runlist must be detected and handled in order for the preemption to complete. 5. If a reset is needed as determined by step 4: a. Halt the memory interface for the engine (as per the relevant engine procedure). b. Reset the engine via NV_PMC_ENABLE. c. Take the engine out of reset and reinit the engine (as per relevant engine procedure) 6. Re-enable scheduling for the engine's runlist via NV_PFIFO_SCHED_ENABLE.
