* gpu: nvgpu: clip target frequencies in arbiterThomas Fleury2017-04-18
| | | | | | | | | | | | | | | | | | | | | It is currently possible to set GPCCLK lower than the minimum allowed frequency. Clip target GPCCLK/MCLK according to valid min/max range in arbiter. We could do this before submitting request to arbiter, but then we would loose information on the requested target frequency. Instead, we cache the clock range in arbiter context, and check target frequency when running arbiter.

* 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.

* gpu: nvgpu: remove fence dependency trackingKonsta Holtta2017-04-11
| | | | | | | | | | | | | | | | | | | | In preparation for better abstraction in job synchronization, drop support for the dependency fences tracked via submit pre-fences in semaphore-based syncs. This has only worked for semaphores, not nvhost syncpoints, and hasn't really been used. The dependency was printed in the sync framework's sync pt value string. Remove also the userspace-visible gk20a_sync_pt_info which is not used and depends on this feature (providing a duration since the dependency fence's timestamp).
