One of the lacking features with output offloading was that screen rotation didn't work at all. This patch makes 0/90/180/270 rotation work with USB output and GPU outputs. When it allocates the shared pixmap it allocates it rotated, and any updates to the shared pixmap are done using a composite path that does the rotation. The slave GPU then doesn't need to know about the rotation and just displays the pixmap. v2: rewrite the sync dirty helper to use the dst pixmap, and avoid any strange hobbits and rotations. This breaks ABI in two places. Signed-off-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Keith Packard <keithp@keithp.com> |
