Description

When using an MPMC with ECC, Performance Monitors, or static PHY, access to the PLB PIM is corrupted. How do I resolve this issue?

Solution

Corruption of PLB accesses may result from the MPMC control port PLB slave not having a unique address range. To resolve this issue, a valid PLB address range should be set for the control port, which does not coincide with the PLB PIM address range. 

An EDK DRC has been added in newer versions to prevent an enabled, but not address ranged, control port from being used. The first version containing this fix is MPMC v4.02.a, to be released in EDK 10.1, Service Pack 2.
