Allocates VRAM in display GPU in case of prime. Then the dma_buf is imported into prime GPU. v2: add comments to make code more readable (Pierre-Eric) removed if check limiting p2p only for matching driver name v3: keep old path for non mesa driver (Michel Dänzer) v4: destroy linear_buffer_display_gpu after import (Michel Dänzer) fall back if linear_buffer_display_gpu alloc fail (Michel Dänzer) Signed-off-by:Yogesh Mohanmarimuthu <yogesh.mohanmarimuthu@amd.com> Acked-by:
