media: platform: rename mtk-vcodec/ to mediatek/mtk-vcodec/

2022-03-18T04:56:51Z

As the end goal is to have platform drivers split by vendor, rename mtk-vcodec/ to mediatek/mtk-vcodec/. Acked-by: Nicolas Dufresne Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: fix debugging defines

2021-11-30T11:18:34Z

The mtk-vcodec uses some internal defined debug formats for printing. This patch fixes some things in those defines: 1. use the 'pr_fmt' define to print function name and line. 2. remove 'if(DEBUG)' condition for the defines. This condition prevents the debugs from being shown in case of dynamic debugs. Instead replace 'pr_info' with 'pr_debug' 3. remove module parameters that enable/disable debug. There is no reason for the driver to have those params. Having those params require the user to explicitly set them when user wants to see debug prints instead of using the global debugs setting as expected by drivers to conform. In addition to that, fix some warnings about debug formatting [hverkuil: used %zu instead of %lu for sizeof() arguments] Signed-off-by: Dafna Hirschfeld Reported-by: kernel test robot Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: abstract firmware interface

2020-09-26T07:53:52Z

MT8183's codec firmware is run by a different remote processor from MT8173. While the firmware interface is basically the same, the way to invoke it differs. Abstract all firmware calls under a layer that will allow us to handle both firmware types transparently.

2020-03-02T14:22:30Z

VP9 bitstream specification indicate segment data should reset to default when meet key frames, intra only frames or enable error resilience mode. So memset segmentation map buffer before every decode process is not appropriate. Reset segment data only when needed, then start decoder hardware Signed-off-by: Rui Wang Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
