Subject: [PATCH v2,00/21] add driver to support secure video decoder
This patch series is consists of four parts. The first is from Jeffrey,
adding secure memory flag in v4l2 framework to support request secure
buffer.
The second and third parts are from John and T.J, adding some heap
interfaces, then our kernel users could allocate buffer from special
heap. The patch v1 is inside below dmabuf link.
https://lore.kernel.org/linux-mediatek/20230911023038.30649-1-yong.wu@mediatek.com/
To avoid confusing, move them into vcodec patchset since we use the
new interfaces directly.
The fourth part is mediatek decoder driver, adding tee interface to
support secure video decoder(svp).
Patch 1~4 add secure memory flag in v4l2 framework with Jeffrey's patch.
Patch 5~7 support allocate dmabufs from specific with John and T.J's patch.
Patch 8~11 initialize tee related interface and parameters.
Patch 12 allocate/free secure memory.
Patch 13 map vsi for secure mode.
Patch 14~16 support one plane capture buffer.
Patch 17~18 re-construct h264 driver to support secure mode.
Patch 19 disable interrupt.
Patch 20 support tee decode.
Patch 21 move init decoder interface to setup queue.
---
Changed in v2:
- remove setting decoder mode and getting secure handle from decode
- add Jeffrey's patch
- add John and T.J's patch
- getting secure flag with request buffer
- fix some comments from patch v1
