I also came across the Interrupt Coalescing feature in NVMe (5.21.1.8 in
Spec 1.4c). It seems to suggest an algorithm based on thresholds for the
maximum interrupt delay time and minimum number of coalesced interrupts.
Klaus, based on your experience, how does this algorithm work? Is is
commonly used by controllers and drivers?
