Details

In the Linux kernel, the following vulnerability has been resolved:

dmaengine: fsl-qdma: fix SoC may hang on 16 byte unaligned read

There is chip (ls1028a) errata:

The SoC may hang on 16 byte unaligned read transactions by QDMA.

Unaligned read transactions initiated by QDMA may stall in the NOC (Network On-Chip), causing a deadlock condition. Stalled transactions will trigger completion timeouts in PCIe controller.

Workaround: Enable prefetch by setting the source descriptor prefetchable bit ( SD[PF] = 1 ).

Implement this workaround.
