[PATCH 4/6] selftests/resctrl: Use cache size to determine "fill_buf" buffer size

2024-08-29 Thread Reinette Chatre
By default the MBM and MBA tests use the "fill_buf" benchmark to read from a buffer with the goal to measure the memory bandwidth generated by this buffer access. Care should be taken when sizing the buffer used by the "fill_buf" benchmark. If the buffer is small enough to fit in the cache then it
