Qlogic ISP 1020
I recently acquired a new tape drive with a HVD SCSI interface. I also got a QLogic ISP 1020 based SCSI card to drive it. Unfortunately, I seem to be having some problems with the qlogicisp driver in the 2.6 kernel. Occasionally I get a SCSI error, and it takes the tape drive offline, since the qlogicisp driver doesn't have proper error handling for 2.6.
Is there a maintainer for the 2.6 qlogicisp driver? I saw that Christoph Hellwig had posted part of a patch to add support for the 1020 and 1040 cards to the qla1280 driver. Has this been completed yet, and if so is there a place I could download the complete patch?
If not, I'd be happy to help test patches for this, as my tape setup is more or less useless to me until I have a driver that has proper error handling.
Alternately, if anyone knows of a working driver for the QLA1020 for a 2.6 kernel, I'd appreciate any pointers.
Thanks,

https://verein.lst.de/~hch/qla1280-isp1040.diff.bz2 has my current patch.
So far I only kno it works with 1040B's on SGI Origins. If you want to
give it a try apply the patch and make sure you have the qla1280 but not the qlogicisp driver in the kernel.
I'll try to split the patch into reasoable chunk soon and feed it to Jes.

I tried this out today, and the results were mixed. Here's the lspci output for this card:
00:0f.0 SCSI storage controller: QLogic Corp. ISP1020 Fast-wide SCSI (rev 05)
When I built a patched driver and plugged it in, here's what I saw in dmesg:
qla1280: no version magic, tainting kernel.
qla1280: QLA1040 found on PCI bus 0, dev 15
scsi(0:0): Resetting SCSI BUS
scsi0 : QLogic QLA1040 PCI to SCSI Host Adapter
Firmware version: 7.65.00, Driver version 3.25
Vendor: Quantum Model: DLT4000 Rev: CD3C
Type: Sequential-Access ANSI SCSI revision: 02
scsi(0:0:2:0): Sync: period 10, offset 12
st: Version 20040213, fixed bufsize 32768, s/g segs 256 Attached scsi tape st0 at scsi0, channel 0, id 2, lun 0
st0: try direct i/o: yes, max page reachable by HBA 1048575
Looked pretty good, other than it seems to think that my card is a 1040 and not a 1020. I then tried to do some operations with my tape drive:
jtlayton@salusa:/usr/src/linux-2.6.4% sudo mt -f /dev/nst0 status SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default). Soft error count since last status=0
General status bits on (1010000):
ONLINE IM_REP_EN
I then tried to use tar to write a file to the tape and it failed almost immediately:
jtlayton@salusa:~% sudo tar cvf /dev/nst0 ./wolf-linux-1.33.x86.run ./wolf-linux-1.33.x86.run
tar: /dev/nst0: Wrote only 0 of 10240 bytes
tar: Error is not recoverable: exiting now
These errors seem to cause these messages to pop up in dmesg:
st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
Please let me know if there's any info I can provide that might help, or if you need me to test another patch.
Heck, I'll even offer up a case of beer (or an equivalent reward) if we can get it working!
Thanks,

Just to mention it, I tried this driver on our Alpha with 2.4.27 (with the mentioned patch), and it runs rock stable, at least after the first 24 hours. This finally solved my problems with md raid1 on the 1020, see posting <[email protected]>,
"oops in qlogicisp.c when running 2.4.27 with md RAID1 on Alpha".
The driver was patched upon 3.24.3 (stolen from kernel 2.6.8.1) and compiles easily on kernel 2.4.27 with some minor updates in include/asm-alpha/io.h. It is also a lot more stable than the infamous feral driver.
Thanks guys, this really made my day.
Norbert, could this be something for the Debian alpha kernels?
