Alex Waterman	0f5818b89e	gpu: nvgpu: Condition debug dump on recovery profiling ... If recovery sequence profiling is enabled skip the debug dump that happens during an MMU fault. This prevents the debug dump from dominating the time spent by the recovery sequence. The debug dump is severly limited in speed by the (lack of) UART bandwidth.

Alex Waterman	811ba85dc6	gpu: nvgpu: Add basic stats to profiler ... Add the ability to print some basic stats to the SW profiler. This doesn't replace a userspace application to do more sophisticated stats analysis if necessary, but it goves some quick basic info. The stats provided are: { Min, Max, Mean, Media, Sigma^2 } JIRA NVGPU-5606 Change-Id: Iadfa5cf1d57657182dcb63e66dd682b54a6fa0de Signed-off-by: Alex Waterman <alexw@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvgpu/+/2367421 Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> Reviewed-by: automaticguardword <automaticguardword@nvidia.com> Reviewed-by: Tejal Kudav <tkudav@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit	2020-12-15 14:13:28 -06:00
Alex Waterman	71ab9800cd	gpu: nvgpu: Add raw data dump for profiler ... Add the ability to dump raw data from the profiler. The kernel driver can provide some simple analysis, but ultimately a userspace tool such as python, R, matlab/octave, or the like, is far better suited for data analysis and visualization.

Alex Waterman	70ce67df2d	gpu: nvgpu: Add a generic profiler ... Add a generic profiler based on the channel kickoff profiler. This aims to provide a mechanism to allow engineers to (more) easily profile arbitrary software paths within nvgpu. Usage of this profiler is still primarily through debugfs. Next up is a generic debugfs interface for this profiler in the Linux code. The end goal for this is to profile the recovery code and generate interesting statistics.
