This series of patches are used to enable the two H264 encoder cores, the difference between encoding process before and after enable two cores is just like as below: As-Is: Synchronous V4L2_VIDIOC_QBUF#0 --> device_run(triger encoder) --> wait encoder IRQ --> encoding done with result --> job_finish V4l2_VIDIOC_QBUF#1 --> device_run(triger encoder) --> wait encoder IRQ --> encoding done with result --> job_finish ... To-Be: Asynchronous V4L2_VIDIOC_QBUF#0 --> device_run(triger encoder) --> job_finish ..V4l2_VIDIOC_QBUF#1 --> device_run(triger encoder) --> job_finish (venc core0 may encode done here, done the encoding result to client) V4L2_VIDIOC_QBUF#2 --> device_run(triger encoder) --> job_finish. --- changes compared with v3: - rebase to the newer linux media stage. - add a capability to indicate scp firmware support multi-core. - probe core0 as main device, core1 as sub-device. changes compared with v2: - update venc core dt-bindings, add two new properties for current usage. - parse venc multi_core mode from device tree. - rebase to the newer linux media stage. changes compared with v1: - of_platform_populate was used in place of the component framework. - new yaml file for venc cores. - some modifications for patch v1's review comments. --- Irui Wang (8): dt-bindings: media: mediatek: vcodec: Adds encoder cores dt-bindings for mt8195 media: mediatek: vcodec: Enable venc dual core usage media: mediatek: vcodec: Refactor venc power manage function media: mediatek: vcodec: Add more extra processing for multi-core encoding media: mediatek: vcodec: Add venc power on/off function media: mediatek: vcodec: Refactor encoder clock on/off function media: mediatek: vcodec: Add multi-core encoding process media: mediatek: vcodec: Return encoding result in asynchronous mode .../media/mediatek,vcodec-encoder-core.yaml | 225 ++++++++++++++++++ .../media/mediatek,vcodec-encoder.yaml | 1 - .../media/platform/mediatek/vcodec/Makefile | 4 +- .../platform/mediatek/vcodec/mtk_vcodec_drv.h | 28 ++- .../platform/mediatek/vcodec/mtk_vcodec_enc.c | 113 ++++++--- .../platform/mediatek/vcodec/mtk_vcodec_enc.h | 11 +- .../mediatek/vcodec/mtk_vcodec_enc_drv.c | 48 +++- .../mediatek/vcodec/mtk_vcodec_enc_hw.c | 159 +++++++++++++ .../mediatek/vcodec/mtk_vcodec_enc_hw.h | 34 +++ .../mediatek/vcodec/mtk_vcodec_enc_pm.c | 177 ++++++++++++-- .../mediatek/vcodec/mtk_vcodec_enc_pm.h | 9 +- .../mediatek/vcodec/mtk_vcodec_util.c | 19 ++ .../mediatek/vcodec/mtk_vcodec_util.h | 3 + .../mediatek/vcodec/venc/venc_h264_if.c | 207 +++++++++++++--- .../mediatek/vcodec/venc/venc_vp8_if.c | 3 +- .../platform/mediatek/vcodec/venc_drv_if.c | 75 ++++-- .../platform/mediatek/vcodec/venc_drv_if.h | 6 + .../platform/mediatek/vcodec/venc_vpu_if.c | 9 +- .../platform/mediatek/vcodec/venc_vpu_if.h | 3 +- 19 files changed, 1015 insertions(+), 119 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/mediatek,vcodec-encoder-core.yaml create mode 100644 drivers/media/platform/mediatek/vcodec/mtk_vcodec_enc_hw.c create mode 100644 drivers/media/platform/mediatek/vcodec/mtk_vcodec_enc_hw.h -- 2.18.0
