    lib: Add igt_pipe_crc_new_nonblock() · 90907450
    Ville Syrjälä authored
    Add support for reading the CRC in non-blocking mode. Useful for tests
    that want to start the CRC capture, then do a bunch of operations, then
    collect however many CRCs that got generated. The current
    igt_pipe_crc_new() + igt_pipe_crc_get_crcs() method would block until
    it gets the requested number of CRCs, whreas in non-blocking mode we
    can just read as many as got generated thus far.
    v2: __attribute__((warn_unused_result)), document the
        new igt_pipe_crc_get_crcs() return value (Daniel)
