* gpu: nvgpu: moved & renamed "struct pmu_gk20a"Mahantesh Kumbar2017-06-05
| | | | | | | | | | | | | | | | | | | - Renamed "struct pmu_gk20a" to "struct nvgpu_pmu" then moved to file "pmu.h" under folder "drivers/gpu/nvgpu/include/nvgpu/" - Included header file "pmu.h" to dependent file & removed "pmu_gk20a.h" include if its usage is not present. - Replaced "struct pmu_gk20a" with "struct nvgpu_pmu" in dependent source & header files.

| | | | | | | | | | | | | | Remove gk20a_platform dependencies from gk20a.h. This makes gk20a_platform a Linux platform specific data structure. Add #include for platform_gk20a.h in the source files that still depend on Linux.

| | | | | | | | | | | | | | gk20a_err() and gk20a_warn() require a struct device pointer, which is not portable across operating systems. The new nvgpu_err() and nvgpu_warn() macros take struct gk20a pointer. Convert code to use the more portable macros.

| | | | | | | | | | | | | | | | | | Most of BIOS parsing code is not specific to any particular GPU. Move most of the code to generic files, and leave only chip specific parts dealing with microcontroller boot into chip specific files. As most of the parsing is generic, they do not need to be called via HALs so remove the HALs and change the calls into direct function calls. All definitions meant to be used outside BIOS code itself are now in <nvgpu/bios.h> Change-Id: Id48e94c74511d6e95645e90e5bba5c12ef8da45d Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/1302222 GVS: Gerrit_Virtual_Submit

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mechanism to reduce lock contention (6) Added callback to notify the arbiter that the VF table has changed and is no longer valid (PMU/Thermals must call this when VF table is invalid) (7) changed internal API to work with MHz (8) added debugfs for stats Change-Id: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