* gpu: nvgpu: wait for stalling interrupts to complete during TSG unbind preemptSagar Kamble2021-05-04
| | | | | | | | | | | | | | | | | | | | | Some of the engine stalling interrupts can block the context save off the engine if not handled during fifo.preempt_tsg. They need to be handled while polling for engine ctxsw status.

* gpu: nvgpu: replace input param chid with pointer to channelDebarshi Dutta2019-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | preempt_channel needs to use the channel to pass it to other public functions, get access to a tsg etc. This qualifies it to take a pointer to a channel as an input parameter instead of a chid. Increment the channel ref counter using the function gk20a_channel_from_id in functions where we get the chid from the h/w registers directly. Once the prempt_channel function call is done, use a gk20a_channel_put on the referenced channel.

* Revert "Revert: GV11B runlist preemption patches"Seema Khowala2018-07-19
| | | | | | | | | | | | | | | | | | | This reverts commit 0b02c8589dcc507865a8fd398431c45fbda2ba9c. Originally change was reverted as it was making ap_compute test on embedded-qnx-hv e3550-t194 fail. With fixes related to replacing tsg preempt with runlist preempt during teardown, preempt timeout set to 100 ms (earlier this was set to 1000ms for t194 and 3000ms for legacy chips) and not issuing preempt timeout recovery if preempt fails, helped resolve the issue.

| | | | | | | | | | | | | | | | | | | | | | | Add NVGPU_IOCTL_CHANNEL_RESCHEDULE_RUNLIST ioctl to reschedule runlist, and optionally check host and FECS status to preempt pending load of context not belonging to the calling channel on GR engine during context switch. This should be called immediately after a submit to decrease worst case submit to start latency for high interleave channel. There is less than 0.002% chance that the ioctl blocks up to couple miliseconds due to race condition of FECS status changing while being read. For GV11B it will always preempt pending load of unwanted context since there is no chance that ioctl blocks due to race condition. Also fix bug with host reschedule for multiple runlists which needs to write both runlist registers.

* gpu: nvgpu: gv11b: add a function to reset pbdma and eng faultedSeema Khowala2017-07-02
| | | | | | | | | | | | | | | | | | | | When Host receives a page fault signal from a CE, Host will immediately set _ENG_FAULTED bit in the NV_PCCSR_CHANNEL register for the channel and will trigger a preempt of the TSG/channel. A channel will only be scheduled when _ENABLED=1, _ENG_FAULTED=0 and _PBDMA_FAULTED=0 in pccsr_channel reg for the channel. If a TSG has a faulted channel, Host will not schedule the entire TSG agin until all _FAULTED bits from channels in the TSG are cleared by SW. This function will be required for ce page fault handling.

The method buffers (one per TSG runqueue) are allocated in BAR2 space during TSG creation All channels in a TSG that are mapped to the same runqueue will point to the same buffer. S/w will insert channel's method buffer pointer in the channel's instance block entries NV_RAMIN_ENG_METHOD_BUFFER_ADDR_LO and NV_RAMIN_ENG_METHOD_BUFFER_ADDR_HI. Method buffer in memory will be 32B aligned. Eng method buffer allocated per tsg will be de-allocated during tsg_release.

* 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.
