http://perforce.freebsd.org/chv.cgi?CH=162648 Change 162648 by mav@mav_mavbook on 2009/05/24 14:47:18 Add driver for AHCI SATA controller to be used as CAM SIM. Driver provides CAM native access to SATA devices reporting transport type XPORT_ATA and protocol type PROTO_ATA and supporting XPT_ATA_IO operation. Comparing to ataahci this driver has: - controller command queueing up to 32 slots (no NCQ yet); - proper DMA load operation without preallocation; It does not supports yet: - ATAPI; - Port Multipliers; - some parts of error reporting and recovery. At this moment driver hacked to only attach JMB363 controller.
