[PATCH v3 0/3] hw/dma: Add error handling for loading descriptions failing

Posted by Fea.Wang 5 months, 2 weeks ago

The original code assumes that memory transmission is always successful,
but in some cases, it gets bus-error.

Add error handling for DMA reading description failures. Do some
reasonable settings, and return the corrected transmission size.
Finally, return the error status.

* Fix the trace format for an unsigned variable

[v2]
* Add DMASR_DECERR case
