* gpu: nvgpu: gv11b: detect stall intr during preemptionSeema Khowala2017-11-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Check for interrupts or hangs while waiting for the preempt to complete. During pbdma/eng preempt done polling, any stalling interrupts relating to the runlist must be detected and handled in order for the preemption to complete. When PBDMA fault or CE fault occurs, the PBDMA will save out automatically. TSG related to the context in which the fault occurred will not be scheduled again until the fault is handled. In the case of some other issue requiring the engine to be reset, TSG will need to be manually preempted. In all cases, a PBDMA interrupt may occur prior to the PBDMA being able to switch out. SW must handle these interrupts according to the relevant handling procedure before the PBDMA preempt can complete. Opt for eng reset instead of waiting for preemption to be finished when there is any stall interrupt pending during engine context preempt completion.

| | | | | | | | | | | | | | | | | | | Reorganize HAL initialization to remove inheritance and construct the gpu_ops struct at compile time. This patch only covers the mc sub-module of the gpu_ops struct. Perform HAL function assignments in hal_gxxxx.c through the population of a chip-specific copy of gpu_ops.
