Hi James,
The existing "aacraid" driver in the upstream kernel tree supports up to
Series-5 controller (3GB/Sec) family.
We launched Series-6 family of RAID controllers (6GB/Sec).
The new Series-6 adapters has PMC-Sierra's advanced ROC(RAID-on-chip)
silicon.
Patch description:
------------------
Added new hardware device interface for PMC-Sierra's SRC based
controller family.
Please review the driver patch and let us know your comments.
Please see the patch below.
Thanks & Regards,
Mahesh
Linux Driver Development Engineer,
PMC-Sierra ODC, Bangalore
This attached patch is against current scsi-misc-2.6.
ObligatoryDisclaimer: Please accept my condolences regarding Outlook's
handling of patch attachments (inline gets damaged, please use
attachment).
