User-space is allowed to submit any property in an async flip as long as the value doesn't change. However we missed one case: as things stand, the kernel rejects no-op FB_ID changes on non-primary planes. Fix this by changing the conditional and skipping drm_atomic_check_prop_changes() only for FB_ID on the primary plane (instead of skipping for FB_ID on any plane).Fixes: 0e26cc72c71c ("drm: Refuse to async flip with atomic prop changes") Signed-off-by: Simon Ser <[email protected]> Reviewed-by: André Almeida <[email protected]> Tested-by: Xaver Hugl <[email protected]> Cc: Alex Deucher <[email protected]> Cc: Christian König <[email protected]> Cc: Michel Dänzer <[email protected]> Cc: Ville Syrjälä <[email protected]> --- André, can you confirm that the R-b still holds?
