The IMX8MQ got two VPUs but until now only G1 has been enabled. This series aim to add the second VPU (aka G2) and provide basic HEVC decoding support. To be able to decode HEVC it is needed to add/update some of the structures in the uapi. In addition of them one HANTRO dedicated control is required to inform the driver of the numbre of bits to skip at the beginning of the slice header. The hardware require to allocate few auxiliary buffers to store the references frame, scaling list or tile size data. The driver has been tested with fluster test suite stream. For example with this command: ./fluster.py run -ts JCT-VC-HEVC_V1 -d GStreamer-H.265-V4L2SL-Gst1.0 This series depends of the reset rework posted here: https://www.spinics.net/lists/arm-kernel/msg875766.html Finally the both VPUs will have a node the device-tree and be independent from v4l2 point of view. ./v4l2-compliance -m 1 v4l2-compliance
