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.
