The working buffer address start and end are calculated in kernel side currently, can't calculate the address end if the driver only getting the address file handle, not the real physical address. Need to extend the vsi to calculate the address end in scp. Re-construct some interface and add config to support extend and non extend at the same time. --- This patch series depends on: [1] https://patchwork.kernel.org/project/linux-mediatek/cover/20241012064333.27269-1-yunfei.dong@xxxxxxxxxxxx --- Yunfei Dong (6): media: mediatek: vcodec: extend h264 video share information media: mediatek: vcodec: remove parse nal info in kernel media: mediatek: vcodec: remove vsi operation in common interface media: mediatek: vcodec: rename vsi to extend vsi media: mediatek: vcodec: adding non extend struct media: mediatek: vcodec: support extend h264 driver .../vcodec/decoder/mtk_vcodec_dec_drv.h | 2 + .../decoder/vdec/vdec_h264_req_multi_if.c | 516 +++++++++++++++++- 2 files changed, 493 insertions(+), 25 deletions(-) -- 2.46.0
