* gpu: nvgpu: Move gp106 HW headersAlex Waterman2017-01-11
| | | | | | | | | | | | | | | | | | | | Move the gp106 HW headers to a new directory specially for them: include/nvgpu/hw/gp106 And change the code to include like so: #include <nvgpu/hw/gp106/hw_fb_gp106.h> This is part of the process to restructure the nvgpu driver.

* gpu: nvgpu: Start re-organizing the HW headersAlex Waterman2017-01-11
| | | | | | | | | | | | | | | | | | | | | | | Reorganize the HW headers of gk20a. The headers are moved to a new directory: include/nvgpu/hw/gk20a And from the code are included like so: #include <nvgpu/hw/gk20a/hw_pwr_gk20a.h> This is the first step in reorganizing all of the HW headers for gm20b, gm206, etc. This is part of a larger effort to re-structure and make the driver more readable and scalable.

* nvgpu: gpu: arbiter for vf switch managementDavid Nieto2016-12-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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mechanism to reduce lock contention (6) Added callback to notify the arbiter that the VF table has changed and is no longer valid (PMU/Thermals must call this when VF table is invalid) (7) changed internal API to work with MHz (8) added debugfs for stats Change-Id: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
