*	gpu: nvgpu: support GMMU mappings for vidmem page allocator	Deepak Nibade	2016-09-01
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Switch to use page allocator for vidmem Support GMMU mappings for page (non-contiguous page allocator) in update_gmmu_ptes_locked() If aperture is VIDMEM, traverse each chunk in an allocation and map it to GPU VA separately Fix CE page clearing to support page allocator Fix gk20a_pramin_enter() to get base address from new allocator Define API gk20a_mem_get_vidmem_addr() to get base address of allocation. Note that this API should not be used if we have more than 1 chunk Jira DNVGPU-96 Change-Id: I725422f3538aeb477ca4220ba57ef8b3c53db703 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1199177 (cherry picked from commit 1afae6ee6529ab88cedd5bcbe458fbdc0d4b1fd8) Reviewed-on: http://git-master/r/1197647 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
*	gpu: nvgpu: Implement a vidmem allocator	Alex Waterman	2016-08-30
	Implement an allocator suitable for managing the video memory on dGPUs. It works by allocating chunks from an underlying buddy allocator and collating the chunks together (similar to what an sgt does in the wider Linux kernel). This handles the ability to get large buffers in potentially fragmented memory. The GMMU can then obviously map the physical vidmem into contiguous GVA spaces.
