SYNOPSIS

void intel_check_cpu_fifo_underruns(struct drm_i915_private * dev_priv);

ARGUMENTS

dev_priv

i915 device instance

DESCRIPTION

Check for CPU fifo underruns immediately. Useful on IVB/HSW where the shared error interrupt may have been disabled, and so CPU fifo underruns won't necessarily raise an interrupt, and on GMCH platforms where underruns never raise an interrupt.
