This feature can reduce total interrupt overhead for RAID setups in some situations, by deferring the interrupt signal until one or both of: a) a specified io_count (completed SATA commands) is achieved, or b) a specified time interval elapses after an IO completion. For now, module parameters are used to set the irq_coalescing_io_count and irq_coalescing_usecs (timeout) globally. These may eventually be supplemented with sysfs attributes, so that thresholds can be set on-the-fly and on a per-chip (or even per-host_controller) basis.

Currently only the 6081 chip qualifies, but other chips may come along someday. Rather than each half of the chip having to satisfy a local set of coalescing thresholds, use of this feature groups all ports together under a single set of thresholds.

Add a quirk that enables blink mode for the LED while NCQ is enabled on any port of a SoC host controller. Normal LED function is restored when NCQ is not enabled on any port. The code to enable the blink mode is based on earlier code and suggestions from Frans Pop, Saeed Bishara, and possibly others.
