[PATCH v3 0/8] Run tests in parallel
Posted by Ian Rogers 1 week, 6 days ago
If command line option '-p' is provided, start/fork all tests in the
main thread and then gather them in order at the end. On a laptop test
time was reduced from 5 minutes 21 seconds to 1 minute 50 seconds. The
option isn't default as the test shows up perf and test flakes.

The '-v' option is modified so that 'perf test -v' will give verbose
output only from failing tests.

v3 - fix a crash if shell test directory isn't found, remove merged patch.
v2 - fix parallel test output/verbose issue
v1 - initial PoC

Ian Rogers (8):
  perf thread_map: Skip exited threads when scanning /proc
  perf list: Add scandirat compatibility function
  perf tests: Avoid fork in perf_has_symbol test
  tools subcmd: Add a no exec function call option
  perf test: Rename builtin-test-list and add missed header guard
  perf tests: Use scandirat for shell script finding
  perf tests: Run time generate shell test suites
  perf tests: Add option to run tests in parallel
