Note: I do not have a machine available to test this yet, I sent this for review to several people who have not replied.

* Add code to the SCSIINT handler for unexpected busfrees and handling immediateJustin T. Gibbs1996-11-221-52/+130
| | | | | | | | | | | | | | SCBs in response to a busfree. When re-queueing an SCB that returned with QUEUE FULL status, reset its timeout.

* Conditionally enable the busfree interrupt to catch unexpected busfrees.Justin T. Gibbs1996-11-222-56/+29
| | | | | | | | | | | | | | | | | | | | | | Immediate SCBs, since they always send messages that tell the target to transition to bus free now rely on the busfree interrupt instead of the IMMEDDONE sequencer interrupt that was generated before. Rearrange some code in the message out loop to give ATN a little more time to drop before we ACK the last byte. Use SPIORDY instead of REQINIT when snooping for a tag message on a reconnect. This is done for the same reasons we use SPIORDY in the inb functions. When going into BITBUCKET mode, turn off HDMAEN in the DFCNTRL register so that we can "not care" what the value of HCNT is. If HCNT is 0, BITBUCKET mode won't transfer any data if HDMAEN is set. Seeing as we don't want the transfer to even think about touching the host, this seems more sane anyway. Thanks to "Dan Willis" <dan@plutotech.com> for pointing out that this was a problem. Notes: svn path=/head/; revision=19921
* Set a more explicit #include path for building aix7xxx_asm, otherwise itPeter Wemm1996-11-222-4/+4
| | | | | | | | | | | | | uses /usr/include/sys/*, which may point to a different build tree. I'm not sure that this is necessary, but there was a question mark over what /usr/include/sys points to when building the "user mode" binaries in the kernel code, especially when building the smp tree. I suspect that the "right" line here is to use ${INCLUDES}, but that causes warnings about unused static inline functions in stdio.h and ctype.h Notes: svn path=/head/; revision=19918

* Change the way Automatic PIO is performed in the mesgin and mesgout phases.Justin T. Gibbs1996-11-211-27/+18
| | | | | | | | | | | | | | SPIORDY should go active on any REQ of the bus, so testing for REQINIT is not necessary. It also seems that testing for SPIORDY is more robust then REQINIT since SPIORDY comes active after REQINIT and PHASEMIS seems to take some time to come true after REQ is asserted if the phase has changed. Of course, none of this is documented. This should give the code savings of my original changes, without breaking the driver on fast peripherals. Notes: svn path=/head/; revision=19906
* Fix UserConfig w/syscons.Nate Williams1996-11-193-6/+6
| | | | | | | | | | | | | | | | The 'getchar' function in syscons (sccngetc) is used by UserConfig to get keyboard input from the user. When it was modified to use the shared keyboard port routines it used the port passed in during the probe routine. Since the probe routine was not yet called, the port was set to 0, which is obviously not going to work. Pre-initialize sc_port to IO_KBD which is really a kludge, but it's how the previous driver did it's job. Found by: remote GDB Notes: svn path=/head/; revision=19869

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Hopefully fix the hangs in the mesgin and mesgout phases that I introduced last week during some code cleanup. I need to get some of these 12MB/s drives so I can reproduce these hangs here... Add a pause disable in the SCB paging case around our manipulation of the QOUTQCNT variable. This is simply extra sanity. Set LASTPHASE to P_BUSFREE once we see a busfree so that the kernel driver can differentiate this from a data out phase. Notes: svn path=/head/; revision=19803
