[gentoo-dev] lm_sensors

[Dave Lee]

Is there an ebuild for lm_sensors?  I was searching google to find info 
about lm_sensors in the portage tree and I was able to find a posting by
someone who had created an ebuild file for it, but again, I cant see it
anywhere in the tree.  Interestingly the posting I found on google was
actually from google's cache as the link was broken, and now when I search
google I get nothing, so they must have crawled lists.gentoo.org recently
and purged the broken links from their cache.

Thanks,
Dave

There is no ebuild for lm_sensors. I have installed it on gentoo with kernel-2.4.16
and lm_sensors 2.6.2 along with i2c-2.6.1. After installing lm_sensors  six different
times with different kernels and on different pcs with different chipsets (required to 
reinstall after kernel or header changes), an ebuild could be made but lm_sensors
will still require a lot of attention to get configured and be useful.

I have always had problems getting the right kernel headers matched with the 
lm_sensors version. It wont compile untill this is matched.  And you will have to
recompile your kernel if it doesn't have i2c support set.

After running the sensors-detect auto-probing, you may still not have the correct
modules detected. In my case with a SIS735 chipset the auto-probe  suggests
a SIS module for the sensors, but in fact i have to use the it87 module.
You'll have to do some research to find the right modules. On my second pc with
a VIA chipset the right module was detected (via-686).

Then the sensors read out has to be calibrated. The voltages and temps are liable
to be very inaccurate untill you have a benchmark to use for calibration.
You will need a BIOS that has hardware-health monitor readings or you will need
an external  temp sensor on the CPU and a voltmeter to take voltage readings.
In all my installs, never have all the readings been accurate before calibration.

Then you will want a program to display the temps and volts on your desktop
and configure that setup . I use gkrellm which has a built-in sensors display.

So an ebuild would be a first step only and would require some work to get sensors
running and calibrated after that. In other words, it wont be a simple emerge process.

So in this case, be careful you dont get what you wish for ;)
