I was wondering if it could be extended to support SATA controllers that aren't mapped to legacy I/O ports. I'm aware of the idex=base,ctl,irq kernel option, but I can't seem to get this to work with my SATA controller (using ide6=base,ctl,irq). The reason I'm asking is because it would seem like a good thing to have SATA controllers that are broadly compatible with IDE to be usable without having to modify the core kernel drivers. This would at least allow a user to perform a Linux install on a SATA drive even if that kernel doesn't have explicit support for the SATA controller. A kernel/driver update can then take place after the install. Also, are there plans for libata to take over the IDE class driver functionality in the future?
