Justin T. Gibbs 74bb76f011 Be even more careful in how we manipulate the QOUTQCNT variable. Now we ... do reset it from the QOUTCNT register inside a pause/unpause. This now happens once per command complete interrupt in the paging case (one interrupt can be for multiple completed commands). I may introduce a counter and do a lazy update in the future, similar to what is done with the QINCNT. Enhance the QUEUE FULL condition handling so that the number of openings will be reduced. This has become more important now that the driver is faster. This code really belongs in the gerneric SCSI layer, as will be the case once 3.0 gets the code from the 'SCSI' branch. Add some #if 0'd out trace code I've been using to help debug sequencer problems. Fix the SCB paging problem that I was seeing. This was only on my 7850 controller and stems from the fact that its QINFIFO can only handle 3bit SCB identifiers. This means that you can only have 8 transactions open at a time with the current paging scheme to these controllers. The code added to enforce this is generic in that it tests for the number of relevent bits that the QINFIFO can store and adjusts the max accordingly. It may be possible to come up with a scheme that allows for more than 8 commands at a time, but I don't know that it is worth the effort simply to fix a low end card. The aic7880 still can do 255. This problem may be related to what Andrey was seeing since I don't have n aic7770 rev E chip here to test on, but as soon as someone probes one of these cards with this new code, the dmesg output will tell the whole story.		1996-11-16 01:19:14 +00:00
