[Xorg-driver-geode] MSR Support for FreeBSD.

[Larry Maloney]

Turns out I'm not getting the MSR information...

I installed the devcpu  package, but getting the MSR info is a little 
different in FreeBSD than linux.

I can see /dev/cpu just fine, but there is no device for MSR (like 
/dev/cpu/msr...)

The doc's for the helper tool x86info says that MSR drivers must be 
included in the kernel, or loaded as a kernel module.

I did that with devcpu,  but I dont' see any MSR pseudo device.

I think the only way to read and write the MSR data is to use IOCTL in 
FreeBSD....

In amd_msr.c, the calls to get the MSR data is  a nice easy  file open. 

I think I"m gonna have to re-write the amd_msr.c for FreeBSD, or just 
add a new file and if_def the build.

If I get MSR working in FreeBSD, what does that give us?  What register 
information is needed to be read and set?  A whole bunch of "stuff" ? :)
