| 2020-02-10 | selftests/resctrl: Add Cache Allocation Technology (CAT) selftest | Fenghua Yu | 1 | -1/+174 | |
| Cache Allocation Technology (CAT) selftest allocates a portion of last level cache and starts a benchmark to read each cache line in this portion of cache. Measure the cache misses in perf and the misses should be equal to the number of cache lines in this portion of cache. We don't use CQM to calculate cache usage because some CAT enabled platforms don't have CQM.

| 2020-02-10 | selftests/resctrl: Add Cache QoS Monitoring (CQM) selftest | Fenghua Yu | 1 | -0/+99 | |
| Cache QoS Monitoring (CQM) selftest starts stressful cache benchmark with specified size of memory to access the cache. Last Level cache occupancy reported by CQM should be close to the size of the memory.
