SubjectHighpoint HPT372N not supported by 2.4.20?
Hello,

i recently bought a Tyan Trinity KT400 S2495 mainboard. It has an
onboard Highpoint RAID controller labelled "Highpoint HPT372N
0236K41N". To my surprise, Kernel 2.4.21-pre5 does not support this
chip. The relevant driver, linux/drivers/ide/pci/hpt366.c, does
support the HPT372, though.

Looking through the Highpoint Web Site, I found a downloadable
opensource driver (at http://www.highpoint-tech.com/372drivers_down.htm).
The revision history said that starting with v1.31 (21Dec2002), the
HPT372N IC is supported. Great.

I downloaded, compiled and insmod'ed the driver, which failed. I then
checked the PCI IDS and to my very surprise, the PCI ID from my chip
(1103:0009) does not match the one required by the Highpoint driver.

Doing further research, nobody seems to know anything about the
1103:0009. I finally submitted the description myself to the Linux PCI
ID Repository at sourcefourge.

So i changed the highpoint driver to detect the HPT372N on my
motherboard (see diff below) and it finally works.

I don't like that solution very much, though, because the highpoint
driver uses the scsi subsystem. Looking through highpoints hpt.c file
I could not find very much differences in the way the HPT372N is
accessed from the HPT372-way. Maybe somebody (Andre Hedrick?) could
look through the code and integrate the HPT372N into
drivers/ide/pci/hpt366.c? This feat is regrettably way beyound
my own programming capability.

I still wonder whether the HPT372N really is so new that it is not yet
listed anywhere. (It is even hard to find on the Highpoint Website).
And I wonder what the difference between HPT372N and HPT372 is.

I would love to hear about the current status of that chip. I do not
need the RAID capability, just the extra IDE ports.

Thank you for your time.

Henning
