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] [1] https://patchwork.kernel.org/project/linux-mediatek/cover/20220122075606.19373-1-yunfei.d...@mediatek.com --- Tinghan Shen (1): media: mtk-vcodec: prevent kernel crash when scp ipi timeout Yunfei Dong (7): dt-bindings: media: mtk-vcodec: Adds decoder dt-bindings for lat soc media: mtk-vcodec: Add to support lat soc hardware dt-bindings: media: mtk-vcodec: Adds decoder dt-bindings for mt8195 media: mtk-vcodec: Adds compatible for mt8195 media: mtk-vcodec: Different codec using different capture format media: uapi: Init VP9 stateless decode params media: mtk-vcodec: Add to support H264 inner racing mode .../media/mediatek,vcodec-subdev-decoder.yaml | 50 +++++++++++++++++++ .../platform/mtk-vcodec/mtk_vcodec_dec.c | 41 +++++++++++++++ .../platform/mtk-vcodec/mtk_vcodec_dec_drv.c | 8 +++ .../platform/mtk-vcodec/mtk_vcodec_dec_hw.c | 12 +++-- .../platform/mtk-vcodec/mtk_vcodec_dec_hw.h | 2 + .../platform/mtk-vcodec/mtk_vcodec_dec_pm.c | 50 +++++++++++++++++++ .../platform/mtk-vcodec/mtk_vcodec_drv.h | 11 ++++ .../mtk-vcodec/vdec/vdec_h264_req_multi_if.c | 23 +++++++-- .../media/platform/mtk-vcodec/vdec_vpu_if.c | 5 ++ drivers/media/v4l2-core/v4l2-ctrls-core.c | 8 +++ 10 files changed, 202 insertions(+), 8 deletions(-) -- 2.25.1
