temperature & fan-control

temperature & fan-control

[Frans van Berckel]

Hi,

Is speeding the fans on a Blade 1000/2000 and Fire 280R well supported
by the kernel? What sensor modules & tools are needed to compile?

Thanks,

Frans van Berckel

Frans,

can't say about the 280R, but the fan control on the Blade 1000/2000
worked until kernel 2.6.29, when it stopped working and hasn't worked
since then. If you downgrade to a 2.6.28 kernel for example, you don't
need any tool for it to work, you just need the CONFIG_ENVCTRL option
enabled in your kernel either as built-in or as a module.

@all: feel free to correct me if i'm wrong :)

Hi Raúl,

Thanks for guiding. Did some testing & checking the envctrl sources, I
found out it got to be the bbc parts for the SunBLADE-1000.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=tree;f=drivers/sbus/char;hb=HEAD

Next I did boot into 2.6.28-6-sparc64-smp but modprobe show's the -22
error while loading the bbc module and does not slow down the fans.

Oct 24 16:35:20 sunbladesrv249 kernel: [  994.142927] i2c-0: Regs at
000007fe7e00002e, 8 devices, own a0, clock 10.
Oct 24 16:35:20 sunbladesrv249 kernel: [  994.145987] bbc_i2c: probe of
f007f00c failed with error -22

So that's faling. I just did upgrade to Sun IEEE Boot Prom 'OBP 4.16.4
2004/12/18 05:18', to be sure but isn't solving my problem.

Did you start a bug ticket yet?


Thanks,

Frans van Berckel

Hi,

maybe it was 2.6.27 the latest working? And no, i didn't file a bug,
feel free to do it yourself.

Building kernels and found out so far, this does the bbc module well ...

linux-image-2.6.27.38-kernelbuilder_2.6.27.38-kernelbuilder

but this one ... does not. 

linux-image-2.6.28.10-kernelbuilder_2.6.28.10-kernelbuilder

A the strange thing is, .27 got newer patches then .28. Next is one of
the first .29.

	Hello,

	2.6.27 is the last usable kernel on Blade 2000. I run a 2.6.28.10 with 
some patches and env_bbc is initialized. Module can be unloaded without 
Oops, but no information is read.

	I have disabled bbc on all my Blades because bbc module (2.6.27) 
randomly returns very strange values (more than 85 °C) and workstation 
switches off. It can happen when these workstations do not run anything. 
These workstations are clean and run without any trouble with Solaris.

	When bbc returns an overheating event, fan speed is not set to its 
maximum value. I have try to debug without any success because I cannot 
reproduce it.

	Regards,

	JKB

Talking about env_bbc the Have you seen how the max1617 i2c devices are
supported in Open Solaris?

max1617.c & envctrl_targets.c

	I have never installed OpenSolaris on these workstations, only Solaris 10.
