H A D | sata_mv.c | diff 6abf4678261218938ccdac90767d34ce9937634f Tue Mar 10 23:56:00 CDT 2009 Mark Lord <liml@rtr.ca> sata_mv: optimize IRQ coalescing for 8-port chips
Enable use of the "all ports" IRQ coalescing optimization for GEN_II / GEN_IIE chips that have dual host-controllers (8-ports). 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.
