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.

media: mtk-vcodec: reset segment data then trig decoder

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

media: mtk-vcodec: vdec: set VPI IPI handler in one place

2019-10-01T19:45:25Z

Each of the supported decoder formats used to set the same RPC interrupt handler by themselves, even though this could be done by the IF init function itself. Move it to the right place and stop making its symbol public. Signed-off-by: Alexandre Courbot Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: remove unneeded proxy functions

2019-06-21T21:10:20Z

We were getting the codec interface through a proxy function that does not bring anything compared to just accessing the interface definition directly, so just do that. Also make the decoder interfaces const. Signed-off-by: Alexandre Courbot Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: mtk-vcodec: avoid unneeded pointer-to-long conversions

2019-06-21T21:09:30Z

The interface used to communicate with the firmware casts pointers into unsigned longs and back again in order to store private references, all of this for pointers that remain purely in the kernel. Replace these unsigned longs with void pointers to make the code a bit sturdier and easier to follow. Also simplify some interfaces by removing arguments that could be infered from others.
