Subject: [PATCH 0/7] selftests/resctrl: Add resctrl selftest

With more and more resctrl features are being added by Intel, AMD
and ARM, a test tool is becoming more and more useful to validate
that both hardware and software functionalities work as expected.

We introduce resctrl selftest to cover resctrl features on both
X86 and ARM architectures. It first implements MBM (Memory Bandwidth
Monitoring) and MBA (Memory Bandwidth Allocation) tests. We can enhance
the selftest tool to include more functionality tests in future.

The tests are in tools/testing/selftests/resctrl in order to have
generic test code for all architectures.

Arshiya Hayatkhan Pathan (2):
  selftests/resctrl: Add mbm test
  selftests/resctrl: Add mba test

Fenghua Yu (1):
  selftests/resctrl: Add the test in MAINTAINERS

Sai Praneeth Prakhya (4):
  selftests/resctrl: Add basic resctrl file system operations and data
  selftests/resctrl: Read memory bandwidth from perf IMC counter and
    from resctrl file system
  selftests/resctrl: Add callback to start a benchmark
  selftests/resctrl: Add built in benchmark
