Eric Anholt ed4cb4142b i915: Add support for MSI and interrupt mitigation. ... Previous attempts at interrupt mitigation had been foiled by i915_wait_irq's failure to update the sarea seqno value when the status page indicated that the seqno had already been passed. MSI support has been seen to cut CPU costs by up to 40% in some workloads by avoiding other expensive interrupt handlers for frequent graphics interrupts.
