Seems > very convoluted to have to setup lkp-tests just for this. Besides, I > tried, but it doesn't work on aarch64... we just follow doc on http://www.phoronix-test-suite.com/ to run tests in PTS framework, so you don't need to care about lkp-tests. and for this fio test, the parameters we used just as: test: fio-1.14.1 option_a: Sequential Write option_b: IO_uring option_c: Yes option_d: Yes option_e: 1MB option_f: Default Test Directory and yeah, we most focus on x86_64 and don't support lkp-tests to run on aarch64... if you have some idea that we could run other tests, could you let us know? it will be great pleasure to run more tests to check for us if we can support.
