Works for me, no more missed IRQs nor hangs/delays with this patchset. I have one questions though - would it be possible to control the interrupts behavior via a module parameter or debugfs entry to simplify debugging of this issue going forward? For example, something like /sys/kernel/debug/dri/0/i915_irq_polling - writing '1' there would enable polling, and '0' would use the usual gen6_ring_get_irq. This would default to '1' on gen7, and '0' on older architectures.
