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.
