Hi Yunfei, thanks for the update, I should be testing this really soon. Le jeudi 31 mars 2022 à 10:47 +0800, Yunfei Dong a écrit : > This series adds support for mt8192 h264/vp8/vp9 decoder drivers. Firstly, refactor > power/clock/interrupt interfaces for mt8192 is lat and core architecture. Similarly to MT8173 and MT8183, a shared* firmware is needed for this CODEC to work (scp.img). I looked into linux-firmware[1] it has not been added for mt8192 yet. As your patches are getting close to be ready, it would be important to look into this so the patchset does not get blocked due to that. best regards, Nicolas [1] https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek * Shared at least between MDP3 and MTK VCODEC from my knowledge > > Secondly, add new functions to get frame buffer size and resolution according > to decoder capability from scp side.
