* drm/atomic: add connector to atomic contextLongChair2018-05-011-1/+27
| | | | | | | | | | This patch adds - DRM connector object to atomic context. - fd property to the drm atomic object as well as a method to read blob type properties. This allows to ensure that the proper connector is picked up, especially when specifying it from the commandline, and also allows to make sure we're using the right one when embedding with interop into an application.
* video: fix double free in drm_atomic_create_contextAnton Kindestam2017-12-031-1/+2
| | | | | | | | | | | | Passing in an invalid DRM overlay id with the --drm-overlay option would cause drmplane to be freed twice: once in the for-loop and once at the error-handler label fail. Solve by setting drmpanel to NULL after freeing it. Also the 'return false' statement after the error handler label should probably be 'return NULL', given that the return type of drm_atomic_create_context returns a pointer.
* Add DRM_PRIME Format Handling and Display for RockChip MPP decodersLionel CHAZALLON2017-10-231-0/+244
This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor struct. That struct holds dmabuf fds and information allowing zerocopy rendering using KMS / DRM Atomic. This has been tested on RockChip ROCK64 device.
