* gpu: nvgpu: New allocator for VA spaceAlex Waterman2015-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new buddy allocation scheme for the GPU's VA space. The bitmap allocator was using too much memory and is not a scaleable solution as the GPU's address space keeps getting bigger. The buddy allocation scheme is much more memory efficient when the majority of the address space is not allocated. The buddy allocator is not constrained by the notion of a split address space. The bitmap allocator could only manage either small pages or large pages but not both at the same time. Thus the bottom of the address space was for small pages, the top for large pages. Although, that split is not removed quite yet, the new allocator enables that to happen. The buddy allocator is also very scalable. It manages the relatively small comptag space to the enormous GPU VA space and everything in between. This is important since the GPU has lots of different sized spaces that need managing. Currently there are certain limitations. For one the allocator does not handle the fixed allocations from CUDA very well. It can do so but with certain caveats. The PTE page size is always set to small. This means the BA may place other small page allocations in the buddies around the fixed allocation. It does this to avoid having large and small page allocations in the same PDE.

They are needed for stopping the counters as late as possible during ctx save and start them as early as possible during context restore. On Maxwell, these registers contain the enable/disable bit.
