> 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.
