In some platforms when asynchronous flips are used all of modifiers/formats mentioned in IN_FORMATS are not supported. This patch adds a new plane property IN_FORMATS_ASYNC to expose the async flips supported modifiers/formats so that user can use this information ahead and done flips with unsupported formats/modifiers. This will save flips failures. v2: Remove async variable from drm_plane (Ville) Signed-off-by: Arun R Murthy --- drivers/gpu/drm/drm_mode_config.c | 7 +++++++ drivers/gpu/drm/drm_plane.c | 6 ++++++ include/drm/drm_mode_config.h | 6 ++++++ 3 files changed, 19 insertions(+) diff --git a/drivers/gpu/drm/drm_mode_config.c b/drivers/gpu/drm/drm_mode_config.c index 37d2e0a4ef4b..cff189a2e751 100644 --- a/drivers/gpu/drm/drm_mode_config.c +++ b/drivers/gpu/drm/drm_mode_config.c @@ -379,6 +379,13 @@ static int drm_mode_create_standard_properties(struct drm_device *dev) return -ENOMEM; dev->mode_config.size_hints_property = prop; + prop = drm_property_create(dev, + DRM_MODE_PROP_IMMUTABLE | DRM_MODE_PROP_BLOB, + "IN_FORMATS_ASYNC", 0); + if (!prop) + return -ENOMEM; + dev->mode_config.async_modifiers_property = prop; + return 0; } diff --git a/drivers/gpu/drm/drm_plane.c b/drivers/gpu/drm/drm_plane.c index a28b22fdd7a4..416818e54ccf 100644 --- a/drivers/gpu/drm/drm_plane.c +++ b/drivers/gpu/drm/drm_plane.c @@ -141,6 +141,12 @@ * various bugs in this area with inconsistencies between the capability * flag and per-plane properties. * + * IN_FORMATS_ASYNC: + * Blob property which contains the set of buffer format and modifier + * pairs supported by this plane for asynchronous flips.
