Hi Michał,

The Amlogic Kernel implements the video pipeline out of the DRM/KMS and v4l frameworks, and
must handle much more uses cases like Video Encoding, Video Capture, ....

The DRM patch integrates the equivalents of amlogic modules : vpu, vout, osd, postprocess managers
The ge2d is not used yep, and encoders will be used to encoder video but will be used with the v4l framework.
