[PATCH V4 11/16] perf/x86/intel/uncore: Add Sapphire Rapids server MDF support

From: kan . liang
Date: Wed Jun 30 2021 - 17:11:02 EST


From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

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.
