From: Babu Moger <[email protected]> Now that the UMC (Unified Memory Controller) perf events can be used to validate the resctrl memory bandwidth numbers on AMD, extend the vendor_specific gate of the MBM and MBA tests to also cover AMD so that they run on AMD in addition to Intel.
The tests stay restricted to Intel and AMD: num_of_mem_controllers() only knows about the iMC and UMC counters, so keeping the gate (rather than making the tests universal) leaves other vendors skipped instead of failing.
