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