[edk2-devel] [PATCH v5 6/6] ShellPkg/AcpiView: Add MPAM Parser
Rohit Mathew
rohit.mathew at arm.com
Mon Oct 2 17:17:34 UTC 2023
Add a parser for the MPAM (Memory system resource partitioning and
monitoring) ACPI table. This parser would parse all MPAM related
structures embedded as part of the ACPI table. Necessary validations are
also performed where and when required.
