The MBM (Memory Bandwidth Monitoring) and MBA (Memory Bandwidth Allocation) features are not enabled for AMD systems. The reason was lack of perf counters to compare the resctrl test results.
Starting with the commit 25e56847821f ("perf/x86/amd/uncore: Add memory controller support"), AMD now supports the UMC (Unified Memory Controller) perf events. These events can be used to compare the test results.
This series adds the support to detect the UMC events and enable MBM/MBA tests for AMD systems.

Please note that resctrl selftest changes flow upstream via the kselftest repo. The latest resctrl selftest changes can be found on the "next" branch there.
