The MBA and CMT tests expect support of other features to be able to run.
When platform only supports MBA but not MBM, MBA test will fail with: Failed to open total bw file: No such file or directory
When platform only supports CMT but not CAT, CMT test will fail with: Failed to open bit mask file '/sys/fs/resctrl/info/L3/cbm_mask': No such file or directory
Extend feature checks to cover these two conditions.
It may be helpful to expand on this more to justify why this is stable material. At this point it sounds as though (from user space perspective) one error is replaced by another. Perhaps just a snippet that states that this fix will cause the test to be skipped on these platforms.
