Subject: [RFC PATCH 0/2] wd719x: Introduce Western Digital WD7193/7197/7296 PCI SCSI card driver
Date: Mon, 11 Nov 2013 22:55:04 +0100 [thread overview]
Message-ID: <201311112255.04967.linux@rainbow-software.org> (raw)
Hello,
this is an attempt to provide a new driver for Western Digital WD7193, WD7197
and WD7296 PCI SCSI controllers based on WD33C296A chip.
It's based on old and ugly wd719x driver written back in 2.0 days, then hacked
to 2.2 and finally to 2.4 kernels. Most of the code is rewritten: from ~4100
lines to ~1200.
I've tested the driver on a WD7193 card with some hard drives and CD-ROMs:
QUANTUM LP240S GM240S01X 4.6
IBM 0663L12 e g
IBM DORS-32160 WA0A
SONY CD-ROM CDU-55S 1.0t
SONY CD-ROM CDU-415 1.1g
The card supports TCQ and linked commands (for cmd_per_lun > 1?) but I don't
know how it should be implemented in a driver.
Device/bus/host resets seem to work fine when tested by sg_reset.
But don't know how to test command abort.
The card requires firmware that can be cut out of the Windows NT driver that
can be downloaded from WD at:
http://support.wdc.com/product/download.asp?groupid=801&sid=27&lang=en
There is no license anywhere in the file or on the page - so I guess that the
firmware cannot be added to linux-firmware.
This script downloads and extracts the firmware:
#!/bin/sh
wget http://support.wdc.com/download/archive/pciscsi.exe
lha xi pciscsi.exe pci-scsi.exe
lha xi pci-scsi.exe nt/wd7296a.sys
rm pci-scsi.exe
dd if=wd7296a.sys of=wd719x-risc.bin bs=1 skip=5760 count=14336
dd if=wd7296a.sys of=wd719x-wcs.bin bs=1 skip=20096 count=514
rm wd7296a.sys
