* gpu: nvgpu: split vidmem_is_vidmemKonsta Holtta2017-06-06
| | | | | | | | | | | | | | | | | | | | | As the vidmem_is_vidmem flag has got two separate meanings in one bit, split it in two bits into the enabled() API: Add NVGPU_MM_HONORS_APERTURE bit, which is the same as vidmem_is_vidmem with its original meaning, and use it to test which aperture bits to write to hardware. Add NVGPU_MM_UNIFIED_MEMORY bit, which has the opposite meaning: that the GPU shares the SoC memory. When this flag is false, the GPU has its own local video memory.

* gpu: nvgpu: Begin removing variables in struct gk20aAlex Waterman2017-05-30
| | | | | | | | | | | | | | | | | | | | | | Begin removing all of the myriad flag variables in struct gk20a and replace that with one API that checks for flags being enabled or disabled. The API is as follows: bool nvgpu_is_enabled(struct gk20a *g, int flag); bool __nvgpu_set_enabled(struct gk20a *g, int flag, bool state); These APIs allow many of the gk20a flags to be replaced by defines. This makes flag usage consistent and saves a small amount of memory in struct gk20a. Also it makes struct gk20a easier to read since there's less clutter scattered through out.

The new wrappers require struct gk20a pointer, and gk20a_fence_wait() did not have access to one. Add struct gk20a pointer as the first parameter.

* gpu: nvgpu: abstract away dma alloc attrsKonsta Holtta2017-03-21
| | | | | | | | | | | | | | | | | | | | | | | | Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but define nvgpu-internal flags for no kernel mapping, force contiguous, and read only modes. Store the flags in the allocated struct mem_desc and only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS abstraction. Rename the notion of attr to flags. Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers allocated via gk20a_gmmu_alloc_vid for consistency. Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr parameter accidentally.

| | | | | | | | | | | | | | | | | | | Move clock APIs from gk20a_platform to gpu_ops. At the same time allow use of internal get_rate/set_rate for querying both GPCCLK and PWRCLK on iGPU. At the same time we can replace calls to clk framework with the new HAL and drop direct dependency to clk framework. gp10b ops were replaced as a whole at HAL initialization. That replaces anything set in platform probe stage, so reduce that to touch only clock gating regs.
