Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: verisilicon: Avoid G2 bus error while decoding H.264 and HEVC<br /> <br /> For the i.MX8MQ platform, there is a hardware limitation: the g1 VPU and<br /> g2 VPU cannot decode simultaneously; otherwise, it will cause below bus<br /> error and produce corrupted pictures, even potentially lead to system hang.<br /> <br /> [ 110.527986] hantro-vpu 38310000.video-codec: frame decode timed out.<br /> [ 110.583517] hantro-vpu 38310000.video-codec: bus error detected.<br /> <br /> Therefore, it is necessary to ensure that g1 and g2 operate alternately.<br /> This allows for successful multi-instance decoding of H.264 and HEVC.<br /> <br /> To achieve this, g1 and g2 share the same v4l2_m2m_dev, and then the<br /> v4l2_m2m_dev can handle the scheduling.
