Merged requested to merge Hazematman/mesa:gallium_default_dmabuf_drm_check into main
Modify the code path taken in
to call DRM to check if
PIPE_CAP_DMABUF is supported. This is
required for overriding the behavior in
to support importing DMABUFs on drivers that don't support DRM, by
simply changing how
PIPE_CAP_DMABUF is handled in their driver.
This change also add supports for
get_screen_fd to all the gallium drivers that are missing this functionality.
