They know full well where all of the aic7xxx driver development is going on and have offered direct support to me as well as the Linux devlopers porting my code. The stuff in the Red Hat announcement makes me laugh though. They make it sound like having Adaptec on their side will solve all of their problems. Support from Adaptec is greatly appreciated, but 95% of the instability problems in the Linux driver can be traced to the mid-level SCSI code. Unless Adaptec funds the rewrite of the Linux SCSI layer, no amount of Adaptec provided source code will help them. I'm still waiting for Adaptec to release sequencer source code (something that the technical marketing people are fighting for) which should aid in working around the aic7880 Rev. B chip problem, but as I've mentioned before, moving to the Adaptec CHIM code would actually reduce the performance of our driver. Adaptec sent me a sequencer design document which verrified that they use a simple SCB management scheme that doesn't fully utilize the capabilities of their chips. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
