323  * intel_set_pch_fifo_underrun_reporting - set PCH fifo underrun reporting state
325  * @pch_transcoder: the PCH transcoder (same as pipe on IVB and older)
328  * This function makes us disable or enable PCH fifo underruns for a specific
329  * PCH transcoder. Notice that on some PCHs (e.g. CPT/PPT), disabling FIFO
330  * underrun reporting for one transcoder may also disable all the other PCH
347 	 * NOTE: Pre-LPT has a fixed cpu pipe -> pch transcoder mapping, but LPT  in intel_set_pch_fifo_underrun_reporting()
348 	 * has only one pch transcoder A that all pipes can use. To avoid racy  in intel_set_pch_fifo_underrun_reporting()

407  * intel_pch_fifo_underrun_irq_handler - handle PCH fifo underrun interrupt
409  * @pch_transcoder: the PCH transcoder (same as pipe on IVB and older)
411  * This handles a PCH fifo underrun interrupt, generating an underrun warning

460  * Check for PCH fifo underruns immediately. Useful on CPT/PPT where the shared
