52 * The code also supports underrun detection on the PCH transcoder.

333 * intel_set_pch_fifo_underrun_reporting - set PCH fifo underrun reporting state
335 * @pch_transcoder: the PCH transcoder (same as pipe on IVB and older)
338 * This function makes us disable or enable PCH fifo underruns for a specific
339 * PCH transcoder. Notice that on some PCHs (e.g. CPT/PPT), disabling FIFO
340 * underrun reporting for one transcoder may also disable all the other PCH
356 * NOTE: Pre-LPT has a fixed cpu pipe -> pch transcoder mapping, but LPT in intel_set_pch_fifo_underrun_reporting()
357 * has only one pch transcoder A that all pipes can use. To avoid racy in intel_set_pch_fifo_underrun_reporting()
358 * pch transcoder -> pipe lookups from interrupt code simply store the in intel_set_pch_fifo_underrun_reporting()
441 * intel_pch_fifo_underrun_irq_handler - handle PCH fifo underrun interrupt
443 * @pch_transcoder: the PCH transcoder (same as pipe on IVB and older)
445 * This handles a PCH fifo underrun interrupt, generating an underrun warning
455 drm_err(&dev_priv->drm, "PCH transcoder %c FIFO underrun\n", in intel_pch_fifo_underrun_irq_handler()
489 * intel_check_pch_fifo_underruns - check for PCH fifo underruns immediately
492 * Check for PCH fifo underruns immediately. Useful on CPT/PPT where the shared
493 * error interrupt may have been disabled, and so PCH fifo underruns won't
