AI-suggested
A fix is available that ensures the g1 and g2 VPUs operate alternately by sharing the same v4l2_m2m_dev, which handles scheduling to avoid simultaneous decoding. Users should apply the updated Linux kernel versions that include this fix. Patch status is confirmed by the resolved vulnerability notice.
Description
A vulnerability in the Linux kernel's media subsystem for the Verisilicon hardware on the i.MX8MQ platform could cause a G2 bus error when decoding H.264 and HEVC streams. This occurs because the g1 and g2 VPUs cannot decode simultaneously due to a hardware limitation, leading to bus errors, corrupted video output, and potential system hangs. The issue is addressed by ensuring that the g1 and g2 VPUs operate alternately, sharing the same v4l2_m2m_dev for proper scheduling.
