* gpu: nvgpu: page align DMA allocsAlex Waterman2017-09-12
| | | | | | | | | | | | | | | | | | | | | | Explicitly page align DMA memory allocations. Non-page aligned DMA allocs can lead to nvgpu_mem structs that have a size that's not page aligned. Those allocs, in some cases, can cause vGPU maps to return an error. More generally DMA allocs in Linux are never going to not be page aligned both in size and address. So might as well page align the alloc size to make code else where in the driver more simple. To imlpement this an aligned_size field has been added to struct nvgpu_mem. This field has the real page aligned size of the allocation. The original size is still saved in size.

* gpu: nvgpu: Deterministic submit fixAlex Waterman2017-08-16
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix some simple pointer arithmetic errors in the deterministic submit path. The lockless allocator was doing a subtraction to determine the correct offset of the element to free. However, this subtraction was using the base address and a numeric offset - not a pointer offset. Thus the difference computed was in bytes not in elements of the block size. The fix is simple: just divide by the block size. Also this modifies the debugging statement a bit so that a bit more information is printed at more useful times. Lastly, a pointer to numeric cast was fixed in the fence code.
