As you might already know, the cedrus driver relies on the Request API, and is a reverse engineered driver for the video decoding engine found on the Allwinner SoCs. This work has been possible thanks to the work done by the people behind libvdpau-sunxi found here: https://github.com/linux-sunxi/libvdpau-sunxi/ I've tested the various ABI using this gdb script: http://code.bulix.org/jl4se4-505620?raw And this test script: http://code.bulix.org/8zle4s-505623?raw The application compiled is quite trivial: http://code.bulix.org/e34zp8-505624?raw The output is: arm: builds/arm-test-v4l2-h264-structures SHA1: 88cbf7485ba81831fc3b93772b215599b3b38318 x86: builds/x86-test-v4l2-h264-structures SHA1: 88cbf7485ba81831fc3b93772b215599b3b38318 x64: builds/x64-test-v4l2-h264-structures SHA1: 88cbf7485ba81831fc3b93772b215599b3b38318 arm64: builds/arm64-test-v4l2-h264-structures SHA1: 88cbf7485ba81831fc3b93772b215599b3b38318 Let me know if there's any flaw using that test setup, or if you have any comments on the patches. Maxime Changes from v2: - Simplified _cedrus_write_ref_list as suggested by Jernej - Set whether the frame is used as reference using nal_ref_idc - Respect chroma_format_idc - Fixes for the scaling list and prediction tables - Wrote the documentation for the flags - Added a bunch of defines to the driver bit fields - Reworded the controls and data format descriptions as suggested by Hans - Reworked the controls' structure field size to avoid padding - Removed the long term reference flag - Reintroduced the neighbor info buffer - Removed the ref_pic_list_p0/b0/b1 arrays that are redundant with the one in the DPB - used the timestamps instead of tags - Rebased on 5.0-rc1 Changes from v1: - Rebased on 4.20 - Did the documentation for the userspace API - Used the tags instead of buffer IDs - Added a comment to explain why we still needed the swdec trigger - Reworked the MV col buffer in order to have one slot per frame - Removed the unused neighbor info buffer - Made sure to have the same structure offset and alignments across 32 bits and 64 bits architecture Maxime Ripard (1): media: cedrus: Add H264 decoding support Pawel Osciak (1): media: uapi: Add H264 low-level decoder API compound controls.
