Re: Phenom II Support

There's a newer, working version...

The previous upload missed a vital call and therefore it only worked on CPU0 and only after suspend/resume. I tried to select only lines from my work-in-progress that were ready for upload, but apparently I overlooked one line.

Re: phc-k8 driver 0.4.4 alpha 1 won't work

I've looked into this, and indeed it doesn't seem to work properly, I forgot one line in the uploaded version. I've uploaded a new alpha version of this driver, could you test and see if it works now? To verify, please also run the hw_pstate_ctrl.py (located and explained in the downloads section as...

Re: phc-k8 driver 0.4.4 alpha 1 won't work

You do need to do it for all cores, but I assume you did... It could be that sensors does not take notice of the changes, maybe it does not measure the voltage at all but reads it once from the pstates at that time? Perhaps it will notice if you restart sensorsd (I'm not particular familiar with the...

Re: phc-k8 driver 0.4.4 alpha 1 won't work

To calculate the voltage, you need to use this formula:
voltage = 1.550 - (0.0125 * vid)

So everything is fine.

And to decrease the voltage for each pstate by 0.2V, you will need to increase each vid by 16...

Re: DKMS support request for phc-intel

You can take a look at the phc-k8 driver, it's really not that complicated to make it work. However, the difficulty is to make it work for multiple kernel versions, e.g. for phc-k8 I had to add a lot of workarounds to make it work in 2.6.32 up to 2.6.36.

What kernel versions should be supported?

At the moment I am working on a newer phc-k8 driver, which will be based on the latest powernow-k8 code. However, since the Cpufreq subsystem has been subject to a lot of changes in the last couple of Linux kernel versions, it already took me quite some effort to add support back to 2.6.32, which is...
