Subject[PATCH V4 11/16] perf/x86/intel/uncore: Add Sapphire Rapids server MDF support
Date
From: Kan Liang <kan.liang@linux.intel.com>

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.
