Unfortunately, no breakdown is shown. In i915_irq.c and intel_display I see: I915_WRITE(GEN6_RP_INTERRUPT_LIMITS, 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. -- Kevin Oberman, Network Engineer, Retired E-mail: rkoberman@gmail.com
