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	f1dc3fd2fb	gpu: nvgpu: Add debugfs wrapper for exposing profilers ... The current debugfs code is completely specific to FIFO's kickoff profiler. But exposing these debugfs nodes is really a perfectly generic operation to any given profiler. Therefore add a generic debugfs interface for exposing profilers. Any code that implements a profiler can now use a single function call to export a profiler to the GPU debugfs area.
