My first attempt at posting this seems to have gone AWOL, so here it comes again. Also being posted to linux-scsi. Here is the first public release of the 2.6.xx driver source code for the Pacific Digital Corporation QStor SATA/RAID chip. This 4-channel chip has hardware-assisted RAID0/RAID1/RAID10, host-queuing, per-request TCQ/NCQ support, support for hot insertion and removal of drives, etc.. The 64-bit/66Mhz chip shows throughput in excess of 200MByte/sec on my ancient P3-1GHz test system, and can do much better when installed in a PCI-X slot. The driver (attached) supports most of the chip features, including host, native and legacy tagged queuing, but does not yet include boot-from-raid support (coming soon). Both hdparm and smartmontools are fully supported by this driver. This patch is against linux-2.6.9-rc2. Please email me any errors or corrections you may deem necessary for kernel inclusion.
