- Summary
- media: verisilicon: Avoid G2 bus error while decoding H.264 and HEVC
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
media: verisilicon: Avoid G2 bus error while decoding H.264 and HEVC
For the i.MX8MQ platform, there is a hardware limitation: the g1 VPU and g2 VPU cannot decode simultaneously; otherwise, it will cause below bus error and produce corrupted pictures, even potentially lead to system hang.
[ 110.527986] hantro-vpu 38310000.video-codec: frame decode timed out. [ 110.583517] hantro-vpu 38310000.video-codec: bus error detected.
Therefore, it is necessary to ensure that g1 and g2 operate alternately. This allows for successful multi-instance decoding of H.264 and HEVC.
To achieve this, g1 and g2 share the same v4l2m2mdev, and then the v4l2m2mdev can handle the scheduling.
