Subject: [PATCH V4 11/16] perf/x86/intel/uncore: Add Sapphire Rapids server MDF support
Date:   Wed, 30 Jun 2021 14:08:35 -0700

The MDF subsystem is a new IP built to support the new Intel Xeon
architecture that bridges multiple dies with a embedded bridge system.

The layout of the control registers for a MDF uncore unit is similar to
a IRP uncore unit.
