Allow setting the block layout of a nouveau FB object using DRM format modifiers. When specified, the format modifier block layout and kind overrides the GEM buffer's implicit layout and kind. The specified format modifier is validated against the list of modifiers supported by the target display hardware. v2: Used Tesla family instead of NV50 chipset compare v4: Do not cache kind, tile_mode in nouveau_framebuffer v5: Resolved against nouveau_framebuffer cleanup Signed-off-by: James Jones <jajones@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
