Hi tony,
I ran selftest/resctrl in my environment, CMT test failed when I enabled Sub-NUMA Cluster.
I don't know why it failed yet, I paste the test results below.
Processer in my environment: Intel(R) Xeon(R) Gold 6254 CPU @ 3.10GHz
$ sudo make -C tools/testing/selftests/resctrl run_tests # # Starting CMT test ... # # Mounting resctrl to "/sys/fs/resctrl" # # Mounting resctrl to "/sys/fs/resctrl" # # Cache size :25952256 # # Benchmark PID: 8638 # # Writing benchmark parameters to resctrl FS # # Checking for pass/fail # # Fail: Check cache miss rate within 15% # # Percent diff=21 # # Number of bits: 5 # # Average LLC val: 9216000 # # Cache span (bytes): 11796480 # not ok 3 CMT: test
Best regards, Shaopeng TAN
