Subject: perf/x86/intel/uncore: Add Sapphire Rapids server IIO support
Git-commit: 3ba7095beaec1bace1b5864fa92b2b7a0eaadf38
Patch-mainline: v5.15-rc1
References: jsc#SLE-18939
The IIO stacks are responsible for managing the traffic between the PCI
Express* (PCIe*) domain and the mesh domain. The IIO PMON block is
situated near the IIO stacks traffic controller capturing the traffic
controller as well as the PCIe* root port information.
The layout of the control registers for a IIO uncore unit is a little
bit different from the generic one.
