mjacob 035b04d47a UltraMode is okay for SBus cards with chiptypes of 1020A. 2000-01-14 08:46:37 +00:00
mjacob 1204bc3a13 Bump up level of some very verbose debugs so that SCSIDEBUG doesn't cause them
to print.
2000-01-06 23:02:51 +00:00
mjacob f90308c0b9 Bump default login time to 60 seconds. Move the spot at
which we claim we've seen the loop up at least once so
that we don't hang forever coming up. Add in the basics
for MI target mode stuff. Force the outer layers to deal
with a FCP response coming back that has a CHECK CONDITION
but no sense data.

mjacob 955d4bb00b clean up some f/w revision stuff. clean up some dualbus stuff. 1999-12-20 00:39:16 +00:00
mjacob edf809c8b6 Dual LVD (1280) support. 1999-12-16 05:35:42 +00:00
mjacob 53ecdaee6c Some queue related functions now use a u_int16_t. Turn some messages into
CFGPRINTF messages. Clear up the f/w download slightly. If less than
rev 5 2100 chip, turn off loop fairness. Clean up a botch or two.
1999-12-04 03:08:18 +00:00
mjacob 7227a97ad0 I was misinformed. I cannot get away from specifying tags for FC. Some devices
are happy w/o them- some are unhappy (IBM drives).

mjacob fb6f289535 nuke a debug printout I thought was already gone 1999-10-26 22:23:20 +00:00
mjacob 864ff761d7 remember to initialize mailbox 2 for FC isp bus resets 1999-10-22 17:06:12 +00:00
mjacob 4938c2371d Some stylistic changes, but also use the new INT_PENDING macro. Start
tracking LIP sequence numbers.
1999-10-17 01:38:27 +00:00
mjacob 2b760bfd7b remove most target mode stuff. Change the arguments to the
isp_fastpost_complete function to include a handle. Do some
isr register debouncing. Use new inline functions for xflist
handle storage. Remove isp_dumpxflist function. Do some fixups
of NVRAM from some broken cards. Use Full Login after LIP option
for FC cards if f/w < 1.17 - there's a f/w bug that causes the
port database to not be actually refreshed for local loop devices!
Do the appropriate endian swizzling for the ICB. Ditto for SNS structures
(these are no-ops until UltraSparc PCI needs them).
1999-10-14 02:27:12 +00:00
mjacob f428cf36fa Change to approved NASA/Ames copyright. Add Fabric support. Fix SCCLUN support.
Add code that tries to track LoopID shifting.
1999-07-05 20:31:35 +00:00
mjacob 61bf929d14 Do a fairly large internal restructuring to accomodate dual-bus host adapters
(e.g., the 1240). Include the new 1080/1240 NVRAM layout reading code. Some
moderately significant mailbox changes were necessary also to accomodate a
second channel.
1999-05-12 18:59:23 +00:00
mjacob cd0cf2b5ca Make firmware revision a triple. Clean up some FC init stuff for
board versions with no BIOS. Separate mailbox interrupts from
IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not
after you clear it (potential race condition). Clear out older broken
BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup
if already in LVD mode. Note usage of presumptive 1040C revision. For
all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state
as unknown as well as marking the need to do a getpdb on targets- after
a LIP for certain the f/w has to do PRLI/PLOGI for all targets again
and marking f/w state as unknown gives us a fighting chance to (start
to) hold up for that to complete.
1999-04-04 02:28:53 +00:00
mjacob 99d46bf762 add isp1080 support and some basic PDB change stuff 1999-03-26 22:39:44 +00:00
mjacob 008b51d0a6 Update the driver with some infrastructure for the 1080. Fix an embarrassing
clock botch bug. Additional infrastructure for PDB change stuff.
1999-03-17 06:15:47 +00:00
mjacob 3c21a2493b Roll internal release tag. Print out if we're in a 64 bit PCI slot.
Use fast memory timing NVRAM parameter. Clean up and fix establishment
of default target parameters. Don't use NVRAM if are flagged as not to
do so (I had a busted NVRAM setup which I couldn't edit that enabled SYNC
mode but disabled disconnect/reconnect and wide!!). Fix delays after
resets. BUS resets not done in isp_init anymore- relegated to OS
specific outer layers. Fix a buglet where you can get in a loop for
a NULL xs in the completion list in isp_intr. Add in some defines that
can disable fast posting. Add in code for Loop Up/Loop Down events that
call into the outer layers as to what to do.
1999-02-09 00:52:23 +00:00
mjacob 6bcdc2b5d2 Implement and use Fast Posting for both parallel && fibre. Redo a bit of
the startup code. Implement a call to outer framework function so that
asynchronous events can be handled (e.g., speed negotiation, target mode).

Roll internal release tags.
1999-01-30 07:31:50 +00:00
mjacob 9d702f60ed + Some basic deadchip detection.
+ Enable FIFO bursts, but also detect bogus 1040A with busted FIFO.
+ Use new MEMZERO crossplatform define.
+ Handle RQCS_QUEUE_FULL status case and let upper layer parse SCSI ststus
  byte if nonzero (should be 0x28- Queue Full status)
+ Fold ISP_NVRAM_FIFO_THRESHOLD_128 into isp_fifo_threshold tag.

mjacob e5e787230b clean up headers; move uninit/watch to outer layers 1998-12-28 19:10:43 +00:00
mjacob 74bc9f26d5 Update HBAs to incorporate the new max_lun property. 1998-12-05 19:43:33 +00:00
mjacob 1dac5b5291 Several changes, including some stub fibre target mode stuff. Establish
a slightly different fibre startup (print ALPA now too). Change
the way that return values from dma setup is done. Make debug messages
out of some queue overflow situations. Turn PORT LOGGED OUT into
Selection Timeout equivlaent. On isp_restart actions don't blow off
the commands with HBA_BOTCH (XS_DRIVER_STUFFUP) - set them with HBA_BUSRESET
(which is defined as XS_DRIVER_STUFFUP until someone decides whether
the suggested change to the midlayer NetBSD is worthy of inclusion).
1998-09-17 23:05:46 +00:00
mjacob 4a1ccd2fe7 turn into a debug message an ABOUT F/W failure. Add ISPCTL_UPDATE_PARAMS isp_control case 1998-09-10 17:10:27 +00:00
mjacob a79310ba38 Major reworking of initialization code, addition of NVRAM reading, usage
of device speed updating, etc... A lot of FC and other case statement
handling. Whew. Too much to really detail here.
1998-09-08 07:28:50 +00:00
mjacob a455ce7531 Locking is now in the outer framework for isp_init/isp_reset- this allows
us to call isp_reset/isp_init internally with impunity.

Rename isp_phoenix to isp_restart and make it global. Clean it up a tad.

If we get an ASYNC_SYSTEM_ERROR code in isp_intr, call isp_restart and
return- the f/w is toasted at this point (usually), so we have to bring
things back to a known state.

In isp_mboxcmd, when we don't see the HOST_INT bit go clear, try and
find out if the isp is trying to tell us something and try again. This
may avoid a potential deadlock where the previous mailbox command hasn't
been cleared by the ISP.

In isp_init don't try and get device parameters if we already have them-
this typically doesn't work if we're in the middle of an isp_restart.
1998-07-18 21:10:16 +00:00
mjacob e8f976016e Some major thrashing to handle building for other than NetBSD.
There is one change of note- build a list of completing commands in
ispintr and then say you're done- this avoids some re-entrancy issues
that had surfaced.

mjacob 128cb933b4 there is an (unimportant) difference between 1020 && 1020A 1998-05-05 22:10:36 +00:00
mjacob 57ca254137 some minor debug printout changes 1998-03-24 23:37:53 +00:00
mjacob fc27ffd92c update some debugging stuff- also turn off possible ULTRA mode for 1020s 1998-03-22 22:02:29 +00:00
thorpej 018aa6e97e Don't include <dev/scsipi/scsipi_conf.h> twice. 1998-02-13 21:58:40 +00:00
mjacob 99139bc35a Fix for port-alpha/4903- always download f/w unless config flags say
no or we have no firmware to download.
1998-01-28 19:09:24 +00:00
thorpej 095c4c092d Adjust for config changes. 1998-01-12 09:23:08 +00:00
mjacob 5ff1a34bba Add a new async notification, and also fix a bug where the queue entry
wasn't getting fully zeroed as it should be.
1997-12-05 19:41:49 +00:00
mjacob 6716542383 A little cleanup and print more error messages. 1997-09-29 01:41:30 +00:00
mjacob f762783999 Wierd- well, what isn't with devices? Anyway, the type code for the ISP
chip on AlphaStation 500 is 2- which wasn't handled, and bad things happened
because the default case wasn't sane. Both are corrected now.
1997-09-13 05:18:30 +00:00
mjacob acd1b90617 Some formatting cleanup, and for the ISP2100, the flags hadn't being set
quite right, but things worked okay anyhow.
1997-09-10 02:18:19 +00:00
bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
1997-08-27 11:22:52 +00:00
mjacob 50d4bdf35c Merge foo. 1997-08-16 00:56:52 +00:00
mjacob 14a7730c16 *Major* differences to support the Qlogic 2100 (Fibre Channel PCI), as well
as being able to do microdifferentiation of the ISP SCSI chip; a couple of
bug fixes, and the beginnings of some watchdog support.
1997-08-16 00:22:11 +00:00
mjacob 002c218565 Kudos and thanks to Mark Brinicombe (mark@causality.com): bug in waiting for
RISC_INT to be set after stuffing a mailbox.
1997-07-28 18:56:36 +00:00
mjacob 68d184dc19 Hmm- seriously funny and sad bug: you need to directly establish the
clock rate for this board on Alpha/PCI systems. Under x86/PCI, the
board f/w will correctly tell you "I'm running at 60Mhz", so the code
that preserved that across a board reset (which would drop the chip
back to 40Mhz) worked fine. On the 8200, the chip was saying "I'm 40Mhz"-
which wasn't true. This turned out to be okay as long as you didn't have
any FAST or UltraFast targets- In fact, setting the chip to 40Mhz allowed
you to run up to 8Mhz SCSI. Unfortunately you die bigtime on the devices
that go faster than that. The fix here is to only use what the chip tells
you the clock rate is in the cases you don't really know (sbus is the
only case where this could be different, although with 66Mhz PCI coming up,
this may change).

thorpej b937ee4745 - Simplify mailbox DMA setup, allowing the front-ends to allocate the
mailbox storage in a way they see fit.
- Define macros to index and size the request and result queue entries.
1997-06-08 06:31:52 +00:00
mjacob 62b3daa7d2 Finally found the cause of that nagging 'lost command' (for the first
command) bug: the initial response queue index is take from mbox 5,
not mbox 4, and mbox 5 wasn't getting initialized to zero.
1997-06-01 23:42:04 +00:00
mjacob 6d4d1f8852 Okay, Charles convinced me that XS_DRIVER_STUFFUP is better than XS_SELTIMEOUT. 1997-04-05 22:36:56 +00:00
mjacob ddc693c299 A) Attempt to get clock rate from ISP chip prior to bashing it over the head
in reset. If none there, try and get from the bus/platform specific code.
If a nonzero value for either, set the clock rate. This is why the PCI
card versions weren't working- they need to be set at 60MHZ, rather than
the default 40MHZ (which worked fine for the internal ISP chips on the
Alpha 8X00).

B) If a isp_poll returns failure (command never completed) to the caller
and no error is set in the xs struct, set XS_SELTIMEOUT. And then call...

C) Added isp_lostcmd function to try and ask the ISP chip about it's current
state as well as the state of commands for a particular target/lun. This is
going along to try and figure out why the very first command to the ISP always
seems to get swallowed up.
1997-04-05 02:53:22 +00:00
cgd da14b3d856 clean up isp_poll() so that it works more correctly. (Modeled on the version
in the BusLogic driver.)
1997-03-23 00:50:07 +00:00
cgd cf26d31ad2 NetBSD RCS ID tweaks, a few comment block tweaks. Also, make copyright
notices consistent (per Matt Jacob).
