phc-k8 on debian sid kernel

[patrick85]

Hi.

I have problems compiling the phc-k8 module on the Kernel 2.6.29 from Debian Sid. The kernel from Lenny (2.6.26) is no problem, but on the Sid-kernel make exits with an error.

I am working with AMD64. Don't know if it's working on i386.

Thanks for any advise.

Since I am unable to run 2.6.29 on my notebook (FGLRX driver doesn't really work, and resume-from-suspend is broken *again*) I haven't really been able to test the driver on 2.6.29. I'll take a look at it ASAP.

Hi David,

There was a change in kernels 2.6.28 (I believe) concerning the way cpumask works (that's what I understand at least, I don't know any C).
See:

cpumask_var_t replaced cpumask_t and some other things changed as well

Unfortunately I couldn't find any clear migration document from the way it was to how it is now containing info on what exactly has changed.

Hope this can be of help.

Yes, I already knew it, it's not in 2.6.28, but I thought it wasn't a problem at the moment, not for 2.6.29 vanilla. Actually I already did the modifications to the newer driver that will support Phenoms/Turion X2 RM/ZM processors... So I'll need to backport while keeping in mind that the driver should still work on for example Ubuntu LTS... It's only the time I lack at the moment, hopefully I get to write and test it later this week.
