* gpu: nvgpu: use coherent aperture for coherent buffersDeepak Nibade2017-07-07
| | | | | | | | | | | | | | | | | Use sysmem_coherent aperture if the buffer mappings are requested to be IO coherent. Use sysmem_noncoherent aperture otherwise. This is implemented by adding a new coherent field to the GMMU attrs struct.

* gpu: nvgpu: Implement PD packingAlex Waterman2017-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases page directories require less than a full page of memory. For example, on Pascal, the final PD level for large pages is only 256 bytes; thus 16 PDs can fit in a single page. To allocate an entire page for each of these 256 B PDs is extremely wasteful. This patch aims to alleviate the wasted DMA memory from having small PDs in a full page by packing multiple small PDs into a single page. The packing is implemented as a slab allocator - each page is a slab and from each page multiple PD instances can be allocated. Several modifications to the nvgpu_gmmu_pd struct also needed to be made to support this. The nvgpu_mem is now a pointer and there's an explicit offset into the nvgpu_mem struct so that each nvgpu_gmmu_pd knows what portion of the memory it's using. The nvgpu_pde_phys_addr() function and the pd_write() functions also require some changes since the PD no longer is always situated at the start of the nvgpu_mem. Initialization and cleanup of the page tables for each VM was slightly modified to work through the new pd_cache implementation. Some PDs (i.e the PDB), despite not being a full page, still require a full page for alignment purposes (HW requirements). Thus a direct allocation method for PDs is still provided. This is also used when a PD that could in principle be cached is greater than a page in size. Lastly a new debug flag was added for the pd_cache code.

* gpu: nvgpu: gmmu programming rewriteAlex Waterman2017-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the high level mapping logic. Instead of iterating over the GPU VA iterate over the scatter-gather table chunks. As a result each GMMU page table update call is simplified dramatically. This also modifies the chip level code to no longer require an SGL as an argument. Each call to the chip level code will be guaranteed to be contiguous so it only has to worry about making a mapping from virt -> phys. This removes the dependency on Linux that the chip code currently has. With this patch the core GMMU code still uses the Linux SGL but the logic is highly transferable to a different, nvgpu specific, scatter gather list format in the near future. The last major update is to push most of the page table attribute arguments to a struct. That struct is passed on through the various mapping levels. This makes the funtions calls more simple and easier to follow.
