14.3 EDK, MPMC v6.06.a - VFBC underrun causes shifted images

描述

After writing a few lines, the video shifts by a few pixels. How do I resolve this issue?

解决方案

This is caused by improper throttling of the underlying NPI interface, leading to NPI/MCB FIFO underruns.

For errors resulting from writes, a patch is available for download at the end of this answer record. To use, extract thezipped patch to the EDK project pcores/ directory, and restart XPS. The MPMC is currently not planned to be updated to include this patch.

A similar failure has been observed for read transactions, but there is no patch currently available.
