This series of patches are used to enable the two H264 encoder cores, encoding process will be changed: 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. There is no "wait encoder IRQ" synchronous call during frame-racing mode encoding process, it can full use the two encoder cores to achieve higher performance. --- This series patches dependent on: [1]: the latest linux stage tree: https://git.linuxtv.org/media_stage.git mtk decoder patches [2]: https://patchwork.linuxtv.org/project/linux-media/list/?series=7105 [3]: https://patchwork.linuxtv.org/project/linux-media/list/?series=7131 new yaml included files [4]: https://patchwork.kernel.org/project/linux-mediatek/list/?series=551641 [5]: https://patchwork.kernel.org/project/linux-mediatek/list/?series=580579 --- --- 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 (10): media: mtk-vcodec: Use core type to indicate h264 and vp8 enc media: mtk-vcodec: export encoder functions dt-bindings: media: mtk-vcodec: Adds encoder cores dt-bindings for mt8195 media: mtk-vcodec: Enable venc dual core usage media: mtk-vcodec: mtk-vcodec: Rewrite venc power manage interface media: mtk-vcodec: Add venc power on/off interface media: mtk-vcodec: Rewrite venc clock interface media: mtk-vcodec: Add more extra processing for dual-core mode media: mtk-vcodec: Add dual core mode encode process media: mtk-vcodec: Done encode result to client .../media/mediatek,vcodec-encoder-core.yaml | 214 +++++++++++++++++ drivers/media/platform/mtk-vcodec/Makefile | 4 +- .../platform/mtk-vcodec/mtk_vcodec_drv.h | 44 +++- .../platform/mtk-vcodec/mtk_vcodec_enc.c | 109 ++++++--- .../platform/mtk-vcodec/mtk_vcodec_enc.h | 7 +- .../platform/mtk-vcodec/mtk_vcodec_enc_core.c | 187 +++++++++++++++ .../platform/mtk-vcodec/mtk_vcodec_enc_core.h | 36 +++ .../platform/mtk-vcodec/mtk_vcodec_enc_drv.c | 118 ++++++---- .../platform/mtk-vcodec/mtk_vcodec_enc_pm.c | 187 +++++++++++++-- .../platform/mtk-vcodec/mtk_vcodec_enc_pm.h | 11 +- .../platform/mtk-vcodec/mtk_vcodec_util.c | 19 ++ .../platform/mtk-vcodec/mtk_vcodec_util.h | 5 + .../platform/mtk-vcodec/venc/venc_h264_if.c | 216 +++++++++++++++--- .../platform/mtk-vcodec/venc/venc_vp8_if.c | 3 +- .../media/platform/mtk-vcodec/venc_drv_if.c | 79 +++++-- .../media/platform/mtk-vcodec/venc_drv_if.h | 7 + .../media/platform/mtk-vcodec/venc_vpu_if.c | 10 +- .../media/platform/mtk-vcodec/venc_vpu_if.h | 3 +- 18 files changed, 1097 insertions(+), 162 deletions(-) create mode 100644 Documentation/devicetree/bindings/media/mediatek,vcodec-encoder-core.yaml create mode 100644 drivers/media/platform/mtk-vcodec/mtk_vcodec_enc_core.c create mode 100644 drivers/media/platform/mtk-vcodec/mtk_vcodec_enc_core.h -- 2.18.0 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
