7 resctrl_tests tests various resctrl functionalities and interfaces including
8 both software and hardware.
10 Currently it supports Memory Bandwidth Monitoring test and Memory Bandwidth
11 Allocation test on Intel RDT hardware. More tests will be added in the future.
12 And the test suit can be extended to cover AMD QoS and ARM MPAM hardware
18 Run "make" to build executable file "resctrl_tests".
23 To use resctrl_tests, root or sudoer privileges are required. This is because
24 the test needs to mount resctrl file system and change contents in the file
27 Executing the test without any parameter will run all supported tests:
34 A test case has four stages:
36 - setup: mount resctrl file system, create group, setup schemata, move test
37 process pids to tasks, start benchmark.
38 - execute: let benchmark run
39 - verify: get resctrl data and verify the data with another source, e.g.
41 - teardown: umount resctrl and clear temporary files.
46 Parameter '-h' shows usage information.
48 usage: resctrl_tests [-h] [-b "benchmark_cmd [options]"] [-t test list] [-n no_of_bits]
49 -b benchmark_cmd [options]: run specified benchmark for MBM, MBA and CQM default benchmark is builtin fill_buf
50 -t test list: run tests specified in the test list, e.g. -t mbm, mba, cqm, cat
51 -n no_of_bits: run cache tests using specified no of bits in cache bit mask
52 -p cpu_no: specify CPU number to run the test. 1 is default
