12.1 EDK, MPMC v6.00.a - VFBC data corruption occurs when writing command when data FIFO almost full/empty

Description

Writing to the VFBC Command FIFO while a Command/transfer is active (vfbc_cmd_idle='0') could cause data corruption in the VFBC read or write FIFO if the command write happens when the write FIFO is near empty or the read FIFO is near full.  How do I resolve this issue?

Solution

This issue is fixed in MPMC v6.02.a, to be released in EDK 12.3.
