* gpu: nvgpu: Move Linux files away from commonTerje Bergstrom2018-06-15
| | | | | | | | | | | | | | | Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent.

* gpu: nvgpu: Set DMA mask on a per-platform basisAlex Waterman2018-06-14
| | | | | | | | | | | | | | | | | | | | Each GPU platform has different DMA limitations. For older chips the maximum size of a DMA buffer was more limited than newer SoCs (read: Xavier) and discrete GPUs. This patch adds support to set the DMA mask for a GPU on a per platform basis by adding a platform field that is populated with the maximum allowed DMA mask. That mask is programmed by the driver common code. If no mask is specified then the default mask size is 16GB (34 bits).

* gpu: nvgpu: Remove gk20a_dbg* functionsTerje Bergstrom2018-05-09
| | | | | | | | | | | | | | | Switch all logging to nvgpu_log*(). gk20a_dbg* macros are intentionally left there because of use from other repositories. Because the new functions do not work without a pointer to struct gk20a, and piping it just for logging is excessive, some log messages are deleted.

* gpu: nvgpu: cache gpu clk rateArun Kannan2018-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | Cache the rate used in clk_set_rate(). Return that cached rate on clk_get_rate(), don't read from hardware. This cached rate is used to avoid duplicate requests to clk_set_rate(). Motivation is to support multiple governors for gpu clk. Reading clock from hardware is unreliable in multi-governor situation. Relying on hardware clock value could mislead the kernel gpu governor in its scaling calculations.
