IPMI smbus and Intel 6300ESB Watchdog drivers

IPMI smbus and Intel 6300ESB Watchdog drivers

[David Härdeman]

Hi,

(third question to LKML today =)

I've recently bought an Intel SE7210TP1-E mainboard (specs here: 
http://www.intel.com/design/servers/boards/SE7210TP1-E/index.htm) and I 
now have most things working.

There are however, two questionmarks left.

1) On the mainboard is a 6300ESB Watchdog Timer (pci id 8086:25ab), but 
there seems to be no driver available for it. Does anyone know if there 
is any such driver in progress or if I've misunderstood the situation?

2) IPMI, Documentation/IPMI.txt mentions a ipmi_smb driver, but I could 
find no such driver in the 2.6.10 tree. Am I missing something?

Thanks in advance for any enlightenment.

Regards,
David Härdeman

You can use the other watchdog in this chip, the TCO timer. The
driver needs a patch to work with 6300ESB.

6300ESB is not a Watchdog Timer. It is an I/O Controller hub that includes a watch dog timer.

If you tell me why you are interested in the WDT, then maybe I will be able answer your question.

Do you get the ISM package that shipped with the board? The ISM software stack in not part of the kernel. The IPMI stuff is part of Server Management.

Thanks, that worked like a charm.

I hope the maintainer for the bk-watchdog tree can pick up and integrate 
the patch so it finds its way to the kernel mainline.

Ah well, I just quoted the output of lspci...

Hummm? In order to have watchdog functionality on the machine? But 
nevermind, I already got that question answered (with the pci id update 
for i8xx_tco).

As for IPMI, I have no idea, I just have no experience of it at all and 
I saw that this mmotherboard supported IPMI so I thought it could be an 
interesting experiment to learn a bit more about IPMI.
