[v2,0/3] hw/dma: Add error handling for loading descriptions failing

Message

Fea.Wang June 4, 2024, 7:15 a.m. UTC

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.

* Add DMASR_DECERR case
* Squash the two commits to one
