The gtt_pwrite slowpath grabs the userspace memory with get_user_pages. This will not work for non-page backed memory, like a gtt mmapped gem object. Hence fall throuh to the shmem paths if we hit -EFAULT in the gtt paths. Now the shmem paths have exactly the same problem, but this way we only need to rearrange the code in one write path. v2: v1 accidentaly falls back to shmem pwrite for phys objects. Fixed. v3: Make the codeflow around phys_pwrite cleara as suggested by Chris Wilson. Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
