[parisc-linux] NCR driver

[parisc-linux] NCR driver

[Matthew Wilcox]

Several people have emailed me and asked if there are any small jobs they
can do to get themselves started.  Here's one that needs doing.  There
is an NCR 53c710 driver in linux/drivers/scsi/ncr53c7xx.c.  This is the
SCSI controller found in the:

	712, 715/{64,80,100}, 725/100, A180

and possibly others.

If anyone is feeling really enterprising (or perhaps just frustrated),
they could try getting this driver to work with the following machines:

	705, 710, 715/{33,50,75}, 720, 725/{50,75}, 730, 735, 750, 755

which contain the NCR 53c700.  The _comments_ in the driver suggest that
it's almost supported, but I don't know how up to date they are.

If you do decide to work on it, please ensure you're working from the
linux-2.3 tree and let everyone know you're working on it.

Hi all,
The LASI SCSI code didn't make it's way into the linux-2.3 tree.
Code in linux/drivers/scsi/lasi* can be migrated now.

Someone else could start trying to make PCI NCR SCSI also work under Dino.
Dino code does detect PCI devices and tulip (100BT) driver has started
talking to it's device. Need to enable CONFIG_GSC_DINO from the default
".config". This requires an A, B, or C-class machine to test though.

cheers,

My apologies.  This oversight has been rectified.

I've gotten the tulip driver to find it's device on the A180, but the
PCI I/O address is being reported incorrectly at some point.  The
pci_ioaddr reported is way too low, so I suspect that there is a Dino
related offset that needs to be added somewhere.  I'm digging into the
Dino code to find the right place to add the offset, and any hints/help
is appreciated.

Here's the output from the tulip driver with debugging turned on:
Found Digital DS21142/3 Tulip at I/O 0x1ff00.

PCI bus walking should work fine.  You can see the devices found by
defining DEBUG in drivers/pci/pci.c, and the vendor and device ids are
listed in devlist.h
