[lm-sensors] ipmisensors to use or not to use?

[lm-sensors] ipmisensors to use or not to use?

[-- Attachment #1.1.1: Type: text/plain, Size: 1071 bytes --]

Hello!

I'm running Linux kernel 2.6.26 and want to get sensor
data from IPMI subsystem via lm-sensors.

In the documentation I read I should use the ipmisensors
modules (the successor of the bmcsensors module).

The latest patch I found, does not compile clearly with
newer kernels. I tried to fix the patch, but after that
failed, I took a closer look and it seems I have to
change too much. So here my question:

 Is the patch still the way to go or should I use
 any other way to get the data via lm-sensors (or
 direct access to /sys)?

Regards
 Sven Anders

Hmm?!
Does nobody know or is nobody willing to answer?

I'm thinking of updating the patch for newer kernel, but
as my time is limited, I would only do this, if it's the
right way and it has a chance to be integrated in the
kernel.

Cheers
 Sven

As I recall, the driver needs to be ported to 2.6.28-rc.  Both it and
ibmpex try to call hwmon_device_register on the bmc device, which causes
problems if someone tries to load both.  I think there was a
general unease with putting it in without some more code review.  The
author doesn't seem to be pushing for its inclusion.  If nothing else, I
did a quick port to 2.6.28-rc5 and it miscategorizes a power meter as a
current sensor and the fan RPM sensors totally don't work.  I might be
able to clean it up a bit and then maybe we can push it into the
scary-upcoming-drivers tree?

Not to mention the usual "just use ipmitool" argument. :)

Blechk.  Also crashes on rmmod, and it seems that the only thing that
works are the voltage sensors.  Lots of strange looking code to convert
sensor readings too.
