MBM (Memory Bandwidth Monitoring) test is the first implemented selftest. It starts a stressful memory bandwidth benchmark and assigns the bandwidth pid in a resctrl monitoring group. Read and compare perf IMC counter and MBM total bytes for the benchmark. The numbers should be close enough to pass the test. Default benchmark is built-in fill_buf. But users can specify their own benchmark by option "-b". We can add memory bandwidth monitoring for multiple processes in the future.
