Re: dma-buf: Add selftests for dma-fence

[Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>]

Hi Chris,

When running the new dmabuf-selftests on two different systems, I get:

    dma-buf: Running sanitycheck
    dma-buf: Running dma_fence
    sizeof(dma_fence)=48
    dma-buf: Running dma_fence/sanitycheck
    dma-buf: Running dma_fence/test_signaling
    dma-buf: Running dma_fence/test_add_callback
    dma-buf: Running dma_fence/test_late_add_callback
    dma-buf: Running dma_fence/test_rm_callback
    dma-buf: Running dma_fence/test_late_rm_callback
    dma-buf: Running dma_fence/test_status
    dma-buf: Running dma_fence/test_error
    dma-buf: Running dma_fence/test_wait
    dma-buf: Running dma_fence/test_wait_timeout
    dma-buf: Running dma_fence/test_stub
    dma-buf: Running dma_fence/race_signal_callback
    thread_signal_callback[0] completed 28855 passes, 3929 misses
    thread_signal_callback[1] completed 28846 passes, 3918 misses
    thread_signal_callback[0] completed 37179 passes, 37179 misses
    thread_signal_callback[1] completed 37184 passes, 37183 misses

and

    dma-buf: Running sanitycheck
    dma-buf: Running dma_fence
    sizeof(dma_fence)=64
    dma-buf: Running dma_fence/sanitycheck
    dma-buf: Running dma_fence/test_signaling
    dma-buf: Running dma_fence/test_add_callback
    dma-buf: Running dma_fence/test_late_add_callback
    dma-buf: Running dma_fence/test_rm_callback
    dma-buf: Running dma_fence/test_late_rm_callback
    dma-buf: Running dma_fence/test_status
    dma-buf: Running dma_fence/test_error
    dma-buf: Running dma_fence/test_wait
    dma-buf: Running dma_fence/test_wait_timeout
    dma-buf: Running dma_fence/test_stub
    dma-buf: Running dma_fence/race_signal_callback
    thread_signal_callback[0] completed 3423 passes, 2148 misses
    thread_signal_callback[1] completed 2360 passes, 9 misses
    thread_signal_callback[0] completed 4028 passes, 4028 misses
    thread_signal_callback[1] completed 8080 passes, 8079 misses

Unfortunately it is not clear to me if this is good or bad?
Perhaps the test output can be improved, e.g. with a clear PASS/FAIL output?

Thanks!

Gr{oetje,eeting}s,
