| | | | | | | | | | | | | | | | | | | | | gv100 cannot use idle filter values defined for gp106 since values are different. Also gv100 cannot use gv11b idle filter values since prod values are different between gv100 and gv11b. Finally since PROD values match with POR INIT values, there is no need to init idle filters for gv100.

* gpu: nvgpu: handle clk arb event posting in OS specific codeSourab Gupta2018-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mechanism of posting events to userspace is OS specific. In linux this works through poll fd, wherein we can make use of nvgpu_cond variables to poll and trigger the corresponding wait_queue. The post event functionality on QNX doesn't work on poll though. It uses iofunc_notify_trigger to post the events to the calling process. As such QNX can't work with nvgpu_cond's. To overcome this issue, it is proposed to create OS specific interface function for posting clk arb events. Linux can call nvgpu_cond based implementation, which makes sense since these are already initialized and poll'ed in Linux specific code only. QNX can implement this interface to call iofunc_notify_* functions, as per its need.

| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | Currently gpu sysfs retrieves Fmax@Vmin by direct call into Tegra DVFS driver that introduces compile time dependencies on CONFIG_TEGRA_DVFS. In addition incorrect clock is used for DVFS information access. Re-factored sysfs node to use generic GPU clock operation for Fmax@Vmin read. This would fix a bug in target clock selection, and allows to remove dependency of sysfs on CONFIG_TEGRA_DVFS. Updated nvgpu_linux_get_fmax_at_vmin_safe operation itself so it can be called on platforms that does not support Tegra DVFS, although 0 will still be returned as Fmax@Vmin on such platforms.

* gpu: nvgpu: poll watchdog status activelyKonsta Holtta2018-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Read GP_GET and GET from hardware every time when the poll timer expires instead of when the watchdog timer expires. Restart the watchdog timer if the get pointers have increased since the previous read. This way stuck channels are detected quicker. Previously it could have taken at most twice the watchdog timeout limit for a stuck channel to get recovered; with this change, a coarse sliding window is used. The polling period is still 100 ms. The difference is illustrated in the following diagram: time 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 get a b b b b b b b b b b b b b b b b b b b b prev - n n n n n n n n n A n n n n n n n n n S next - A s s s s s s s s s S "time" represents wall time in polling units; 0 is submit time. For simplicity, watchdog timeout is ten units. "get" is the GP_GET that advances a little from a and then gets stuck at b. "prev" is the previous behaviour, "next" is after this patch. "A" is when the channel is detected as advanced, and "S" when it's found stuck and recovered; small "s" is when it's found stuck but when the time limit has not yet expired and "n" is when the hw state is not read.

* gpu: nvgpu: create a wrapper over sync_fencesDebarshi Dutta2018-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch constructs an abstraction to hide the sync_fence functionality from the common code. struct nvgpu_os_fence acts as an abstraction for struct sync_fence. struct nvgpu_os_fence consists of an ops structure named nvgpu_os_fence_ops which contains an API to do pushbuffer programming to generate wait commands for the fence. The current implementation of nvgpu only allows for wait method on a sync_fence which was generated using a similar backend(i.e. either Nvhost Syncpoints or Semaphores). In this patch, a generic API is introduced which will decide the type of the underlying implementation of the struct nvgpu_os_fence at runtime and run the corresponding wait implementation on it. This patch changes the channel_sync_gk20a's semaphore specific implementation to use the abstract API. A subsequent patch will make the changes for the nvhost_syncpoint based implementations as well.

We do not support bare channels without TSG, and if channel is not part of TSG then it means channel is already unbound from TSG with call to NVGPU_TSG_IOCTL_UNBIND_CHANNEL, and there is nothing to do while closing the channel Bug 200327095 Jira NVGPU-229 Change-Id: Ib7f6710f0dc8125caafabe7bee737622c3dd9fa3 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1708902 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
