Collecting CRC may result in a modeset and extra vblank waits. On some tests this will increase the runtime a lot, so it makes sense to keep it enabled, and only collect the most recent CRC when needed. Changes since v1: - Fix read_crc semantics. (Ville) Changes since v2: - Remove EAGAIN assert, can be reached from drain_crc. Changes since v3: - Do not infinitely loop in igt_pipe_crc_drain().
