(CPU) pipe to set state for
whether underruns should be reported or not
This function sets the fifo underrun state for
pipe. It is used in the
modeset code to avoid false positives since on many platforms underruns are
expected when disabling or enabling the pipe.
Notice that on some platforms disabling underrun reports for one pipe disables for all due to shared interrupts. Actual reporting is still per-pipe though.
Returns the previous state of underrun reporting.
