Can't find watchdog timer (sc1200)

Can't find watchdog timer (sc1200)

[Roy Sigurd Karlsbakk]

Hi

I can't make linux (2.4.19-rc1) detect the watchdog timer in the sc1200. Any 
ideas? 

Should this one show up in /proc/pci?

output from cpuinfo is below

thanks

roy

Its only in -ac, mainly because its untested and experimental. Check 
2.4.19-pre10-ac2

When it's hard linked, I can't find anything
Haven't tried with module yet

there is no code for sc1200 in the pre10-ac2 patch. it's all in the official, 
and nothing has changed to -pr1

any other suggestions?

I'm not all that sure if that driver works on the sc1200 because that
driver tries to talk to the watchdog in the SuperI/O chip and that
chip has another watchdog circuit too.  I've written a driver for the
other watchdog chip, so if you can, please try this patch against a
2.4.9-pre10 kernel:

   http://basselope.nano-system.com/~wingel/scx200_wdt.diff

This patch is a part of my patches for the NatSemi SCx200 family of
chips, so I hope I haven't missed anything.  If it works for you,
please drop me a mail and I'll try to get it included in the main
kernel.

I guess that'll be 2.4.19-pre10? :-)

Thanks, but I'll wait till I get new hardware. the Samsung STCs I were trying 
out were in early beta.

Correct, my bad.

I've been reading the data sheets for the SC2200 and it seems as if
the watchdog is gone from the integrated SuperI/O, so you should use
my driver instead.  Zwane Mwaikambo's driver ought to work on the
NatSemi PC97317 SuperI/O.  Hm, I think I have some hardware that I
should be able to test that on.

Oh well, I think I'll just submit my driver to Marcelo and see what
happens.  I've cleaned up the driver a bit since the last time I
tried.
