Hi. I'm glad to present new driver (mvs) for several series of Marvell SATA controllers (PCI-X, PCIe and SoC-integrated), to work with CAM ATA infrastructure. Driver supports following Marvell chips: Gen-I (SATA 1.5Gbps): 88SX5040, 88SX5041, 88SX5080, 88SX5081 Gen-II (SATA 3Gbps, NCQ, PMP): 88SX6040 ,88SX6041 (including Adaptec 1420SA), 88SX6080, 88SX6081 Gen-IIe (SATA 3Gbps, NCQ, PMP with FBS): 88SX6042, 88SX7042 (including Adaptec 1430SA); 88F5182, 88F6281, MV78100 SoCs. , same as atamarvell + ataadaptec + atamvsata legacy ata(4) drivers together. Driver supports most of hardware features, including command queues, NCQ, Port Multipliers, hot-swap, SATA power management, Command Completion Coalescing, Asynchronous Notifications and MSI. Driver also supports ATAPI devices, though it may be not very reliable due to strange ATA shadow registers behavior in these chips. I've successfully tested it with Supermicro SAT2-MV8 (88SX6081) on i386 and sparc64, Adaptec 1430SA (88SX7042) on i386, and SheevaPlug (88F6281) on arm. I haven't tested it on Gen-I chips due to lack of such hardware. Complete fresh patch for HEAD can be found here: http://people.freebsd.org/~mav/mvs.20100328.patch (make sure to run patch with -p to create directories). Testing results, comments and feedback welcome. Special thanks to iXsystems, Inc. for supporting this work. -- Alexander Motin
