* gpu: nvgpu: Move MC HAL to commonTerje Bergstrom2018-09-13
| | | | | | | | | | | | | | | | | | | | | | | Move implementation of MC HAL to common/mc. Also bump gk20a implementation to gm20b. gk20a_mc_boot_0 was used via a HAL, but we have only one possible implementation. It also has to be anyway called directly to detect which HALs to assign, so make it a true common function. mc_gk20a_handle_intr_nonstall was also used only in os/linux/intr.c so move it there.

* gk20a: nvgpu: Remove io.h dependency from gk20a.hDebarshi Dutta2018-07-30
| | | | | | | | | | | | | | | | In the current code, gk20a.h includes io.h which gets directly included in a lot of other files. io.h contains methods which uses a struct gk20a as a parameter leading to a circular dependency between io.h and gk20a.h. This can be mitigated by removing io.h from gk20a.h as part of larger effort to moving gk20a.h to nvgpu/gk20a.h JIRA NVGPU-597 Change-Id: I93e504fa9371b88152737b342a75580c65e8f712 Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1787316 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* 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.

* 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.
