Subject: RE: [PATCH v2 0/7] x86/resctrl: Add support for Sub-NUMA cluster (SNC) systems

Message-ID: <TYAPR01MB6330B9B17686EF426D2C3F308B25A@TYAPR01MB6330.jpnprd01.prod.outlook.com> (raw)

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
