gpu: nvgpu: add support for L3 cache allocation of buffers
Add gv11b implementation of gpu_phys_addr() that checks the t19x GMMU attributes struct to determine if L3 allocation should be enabled. If L3 alloc is enabled then a special physical address bit is set. Add flag NVGPU_AS_MAP_BUFFER_FLAGS_L3_ALLOC to struct nvgpu_as_map_buffer_ex_args so that User space can add a hint to allocate buffer in L3 cache Jira GPUT19X-10 Bug 200279508 Change-Id: I1bb9876a670b252980922aa50e3e69b802be137f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master/r/1512602 GVS: Gerrit_Virtual_Submit Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com>
