* gpu: nvgpu: Move secure_alloc to struct gk20aTerje Bergstrom2017-05-11
| | | | | | | | | | | | | | | | | | Move the function pointer for VPR page allocation to struct gk20a and use it from there. At the same time remove secure_page_alloc pointer and add a direct call to it in probe. Move platform_tegra.h as tegra/linux/platform_gk20a_tegra.h, as it's only declaring functions defined in platform_gk20a_tegra.c to other files in the same directory.

* gpu: nvgpu: use correct flags for secure allocsKonsta Holtta2017-04-26
| | | | | | | | | | | | | | | | The gfp_t argument for dma_alloc_attrs() cannot take DMA_MEMORY_NOMAP - it's interpreted as __GFP_RECLAIMABLE which has the same integer value. Use GFP_KERNEL for the flag argument and set DMA_ATTR_NO_KERNEL_MAPPING for dma attrs which the code was trying to do with the flag that is meant for the coherent allocation API.

* gpu: nvgpu: Move semaphore impl to nvgpu_memAlex Waterman2017-04-25
| | | | | | | | | | | | | | | | | | | Use struct nvgpu_mem for DMA allocations (and the corresponding nvgpu_dma_alloc_sys()) instead of custom rolled code. This migrates away from using linux scatter gather tables directly. Instead this is hidden in the nvgpu_mem struct. With this change the semaphore.c code no longer has any direct Linux dependencies.

| | | | | | | | | | | | | | | | | | | | | | Add an API for creating a special sub-nvgpu_mem struct. This struct comes with some fairly important caveats but is very useful for the semaphore code. Also, make sure that in nvgpu_mem_begin() and nvgpu_mem_end() no additional mappings are made if not necessary. More importantly during nvgpu_mem_end() it would be possible to vunmap() a CPU mapping of a DMA allocation that does not expect this to happen.
