Descriptions

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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: fsl-qdma: corrección El SoC puede bloquearse en lecturas no alineadas de 16 bytes. Hay erratas en el chip (ls1028a): El SoC puede bloquearse en transacciones de lectura no alineadas de 16 bytes mediante QDMA. Las transacciones de lectura no alineadas iniciadas por QDMA pueden detenerse en el NOC (Network On-Chip), provocando una condición de interbloqueo. Las transacciones detenidas activarán tiempos de espera de finalización en el controlador PCIe. Solución alternativa: habilite la captación previa estableciendo el bit de captación previa del descriptor de origen ( SD[PF] = 1 ). Implemente esta solución.
