* gpu: nvgpu: Fix submit profiling stat reportingPeter Boonstoppel2017-04-17
| | | | | | | | | | | | | | | | | | | The debugfs submit profiling stats report the distribution of submit times at different percentiles. The original code reports the lowest entry in every percentile-bin as being representative for that bin. This means that where debugfs reports the 50th percentile, it actually reports the ~45.001th percentile. This is especially inconveniant when looking at the 100th percentile, which does not in fact reflect the maximum. This patch changes the code to instead report the highest entry in every percentile-bin.
