[Xen-devel] CPUFREQ on a bread-and-butter AMD 4050e part II was: AMD P-States not recognized for Xen 3.3 and 3.4

["Carsten Schiers" <carsten@xxxxxxxxxx>]

So, I continued my deep-dive into cpufreq handling for the above 
mentioned CPU.

Compiled and installed xen-unstable.hg and linux-2.6.18-xen.hg as of 
16.01.09
with the config from the original Bastian Blank (waldi) kernel I use. 

I left out dist/install/etc/xen because it killed my network config. 
Hope this
doesn't introduced finding 3.

Finding 1 (good!):      no powernow-k8 out of synchs anymore!
Finding 2 (good!):      no TSC drifts anymore!
Finding 3 (bad):                DomUs with PCI devices handed over complain 
that they need also the
                                PCI device of the VGA card (although it doesn't 
share an IRQ with the
                                card in question. 

Although I still have trouble to treat the CPU so bad that the ondemand 
governor accelerates
a bit, I am thinking I'm on the right way. 

This a bit of reporting just in case others check out the same 
configuration.

BR,
Carsten.
