* nvgpu: clk: MISRA Rule 21.2 header guard fixessmadhavan2018-09-14
| | | | | | | | | | | | | | | | | | | | | | | MISRA rule 21.2 doesn't allow the use of macro names which start with an underscore. These leading underscores are to be removed from the macro names. This patch will fix such violations in clk by renaming them to follow the convention, 'NVGPU_PARENT-DIR_HEADER-NAME' when there is no keyword repetition between file name and directory or 'NVGPU_HEADER-NAME' when there is repetition.

* gpu: nvgpu: fix some MISRA 10.3 violationsPhilip Elcan2018-09-10
| | | | | | | | | | | | | | | | Fix MISRA 10.3 violations in mclk_gp106.c. Cleanup cases where values were being assigned to narrower types. Changes in mclk_gp106.c required updates to other files to resolve errors and prevent introducing new violations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JIRA DNVGPU-143 The arbiter is charged with selecting the proper frequencies when multiple applications submit simultaneously clock change requests On the current implementation, the arbiter guarantees that the selected frequency will be always higher or equal to the request, as long as the request is in range. The current code is not yet realtime friendly, as requests are not pre-allocated. Summary of changes: (1) pstate/vf switch no longer selects boot frequency (2) changed mclk code change to accept input freq (3) added arbiter (4) now a single session can submit concurrent requests the last request is the one that applies for that session (5) modified locking mechanism to reduce lock contention (6) Added callback to notify the arbiter that the VF table has changed and is no longer valid (PMU/Thermals must call this when VF table is invalid) (7) changed internal API to work with MHz (8) added debugfs for stats Change-Id: I6a7b05c9447761e8536f84ef86b5ab0793164d63 Signed-off-by: David Nieto <dmartineznie@nvidia.com> Reviewed-on: http://git-master/r/1239461 Reviewed-by: Thomas Fleury <tfleury@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/1267120 Reviewed-by: Automatic_Commit_Validation_User
