This is a major rewrite from the original -Adaptec supplied driver. It has signficantly cleaned up both the code -and the running binary size (the module is less than half the size of -the original). - -Supported Cards/Chipsets -------------------------- - Adaptec 2020S - Adaptec 2025S - Adaptec 2120S - Adaptec 2130S - Adaptec 2200S - Adaptec 2230S - Adaptec 2240S - Adaptec 2410SA - Adaptec 2610SA - Adaptec 2810SA - Adaptec 21610SA - Adaptec 3230S - Adaptec 3240S - Adaptec 4000SAS - Adaptec 4005SAS - Adaptec 4800SAS - Adaptec 4805SAS - Adaptec 5400S - Dell PERC 2 Quad Channel - Dell PERC 2/Si - Dell PERC 3/Si - Dell PERC 3/Di - Dell CERC 2 - HP NetRAID-4M - Legend S220 - Legend S230 - IBM ServeRAID 8i - ICP 9014R0 - ICP 9024R0 - ICP 9047MA - ICP 9087MA - ICP 9085LI - ICP 5085AU - -People -------------------------- -Alan Cox <alan@redhat.com> -Christoph Hellwig <hch@infradead.org> (updates for new-style PCI probing and SCSI host registration, - small cleanups/fixes) -Matt Domsch <matt_domsch@dell.com> (revision ioctl, adapter messages) -Deanna Bonds (non-DASD support, PAE fibs and 64 bit, added new adaptec controllers - added new ioctls, changed scsi interface to use new error handler, - increased the number of fibs and outstanding commands to a container) - - (fixed 64bit and 64G memory model, changed confusing naming convention - where fibs that go to the hardware are consistently called hw_fibs and - not just fibs like the name of the driver tracking structure) -Mark Salyzyn <Mark_Salyzyn@adaptec.com> Fixed panic issues and added some new product ids for upcoming hbas. Performance tuning, card failover and bug mitigations. - -Original Driver -------------------------- -Adaptec Unix OEM Product Group - -Mailing List -------------------------- -linux-scsi@vger.kernel.org (Interested parties troll here) -Also note this is very different to Brian's original driver -so don't expect him to support it. -Adaptec does support this driver.
