It's defined in /sys/dev/drm2/i915/i915_reg.h. Unfortunately, no breakdown
is shown. In i915_irq.c and intel_display I see:
                   18 << 24 |
                   6 << 16);

The exact same code appears in both and these are the only references to
that  I can find. This leaves my with no more idea than I had before I
looked. maybe someone has more of a clue.
