Firstly, add mt8195 soc lat hardware and compatible, then add documents. For vp8 only support MM21 mode, H264/vp9 support MT21C, need to separate them. Next, initialize vp9 stateless decoder parameters. Lastly, enable H264 inner racing mode to reduce hardware latency.
Patch 1~4 add mt8195 soc lat hardware and compatible, then add documents. Patch 5 using different format for different codecs. Patch 6 prevent kernel crash when scp reboot. Patch 7 init vp9 stateless decoder parameters. Patch 8 enable H264 inner racing mode to reduce hardware latency. --- This patch depends on "support mt8186 decoder"[1]

Vp8 need to use MM21, but vp9 and h264 need to use HyFbc mode for mt8195. Vp8/vp9/h264 use the same MM21 format for mt8192.

When SCP timeout during playing video, kernel crashes with following message. It's caused by accessing NULL pointer in vpu_dec_ipi_handler. This patch doesn't solve the root cause of NULL pointer, but merely prevent kernel crashed when encounter the NULL pointer.
After applied this patch, kernel keeps alive, only the video player turns to green screen.

Hello Yunfei,
This patch is not strictly related to MediaTek SoCs, since it's modfying v4l2-core. Can you please send this patch separately?
Thanks, Angelo
Hi AngeloGioacchino,
Thanks for your suggestion,
Separate this patch with mt8195 support, and sent it again. On Thu, 2022-01-27 at 11:35 +0100, AngeloGioacchino Del Regno wrote:
