Hello group.

Does anyone know if the HPT/TRIONES 302 chip used on the Highpoint Rocket
133 (2 channel) ATA133 controller can be used with OpenBSD? I took a look in
the kernel sources (pciide code), and found that there are several other 3xx
chips supported. It would be nice if someone could add support for this chip
as well. I would be happy to do it myself, but I can't get hold of any
documentation on the net, and Highpoint support just referred me to the semi
opensource linux driver, which uses a precompiled hpt302lib.o file.
Furthermore the linux driver architecture is completely different from
OpenBSD's and I have too little time and skills to try and figure all that
out manually...

Thanks in advance

it may be as simple as adding the right numbers to the pciide files. (no
code to write, just make it match your device.) it may also be more
complicated. the freebsd change to support it was this simple.
see sys/dev/ata/ata-chipset.c in freebsd src. report back if it works
please.

Hello again.

I looked at the code from FreeBSD and it turns out the HPT302 acts like a
HPT372, so I just altered the folliwing files in /usr/src/sys/dev/pci:

pcidevs:
Added product ID for the HPT302 (0x06)
pcidevs.h:
Added it here as well
pciide_hpt_reg.h:
Defined the revision of the HPT302 (0x01) and added the pio, dma and
udma codes for the HPT372

Values were taken from the FreeBSD code and adapted to the OpenBSD data
model

pciide.c:
Added to pciide_triones_products[] the necessary definition with reference
to the hpt_chip_map function.

altered hpt_chip_map() to include checks for the HPT302 in relevant places

altered hpt_setup_channel() to checp for and set up the HPT302 (separately,
I didn't feel comfortable adding confusion to existing code).

That is all there was to it! The machine is up and working now, and it seems
to be stable so far, although I haven't tested it for more than a few hours.
Once I feel more comfortable that the code is stable, I'll clean up the code
and create patches for 3.3 if anyone is interested. My knowledge is limited
though, so I won't vouch for my patch to be production grade or even work in
another system :-)

Cheers
