This test simply counts how many times `eventfd_read()` and `eventfd_write()` can be called on an `eventfd(0, EFD_SEMAPHORE | EFD_NONBLOCK)` file descriptor. Prior to the recent changes in `eventfd`, we were seeing approximately < 1000 writes / s. However, the previous `eventfd` implementation would fail this test with the result that the number of successful reads was far greater than the number of successful writes. This should be impossible, and with the recent `eventfd` changes that was fixed. Additionally, we are seeing an increase in over 40x for non-blocking eventfd reads and writes. ``` START - test_stress I: BOARD: qemu_riscv64_smp I: TEST_DURATION_S: 5 I: UPDATE_INTERVAL_S: 1 I: avg: 48537 reads/s I: avg: 48575 writes/s PASS - test_stress in 5.002 seconds ``` Signed-off-by: Christopher Friedt <cfriedt@meta.com> |
