Powernow-k8 support
Hi,
I recently subscribed to xen-users asking about a powernow-k8 problem,
but in the meantime I am not sure if the users-list was the right place
for it. So I decided to repeat my question here ;-)
My current config is attached.

Powernow-k8 support?

Hello
I'm building a router/proxy/firewall, the default governor is

Thanks at all!

Powernow Failure with Xen Kernel
Sorry to have so many questions but I seem to have quite a few mini
problems with my first Xen setup. My xen server works fine with Powernow
on the standard Kernel but with the Xen kernel it fails. Does anyone
know why? Details below.
With Standard Kernel

[PATCH 1/2] cpufreq, powernow: enable/disable core performance boost for all cpus in policy
Currently, enable/disable turbo mode on AMD is broken:
$ xenpm enable-turbo-mode 0 <-- works and proper CPU MSR bit is set
$ xenpm enable-turbo-mode 1 <-- silently broken, MSR bit not set
Since ->turbo is per policy, when user requests to enable/disable
turbo mode, we need to set the bit in all of the ->cpus that this
policy affects.

[PATCH] powernow: don't read never initialoized structure member
c/s 20361:51b031b0737e removed the writing of struct
processor_performance''s shared_cpu_map member, but the powernow driver
still has code to read it (though presumably that code path can''t be
taken on actual hardware supported by the powernow driver). Remove the
use of the field along with the field itself.

powernow error in Xen VM with new kernel
I just upgraded my first Xen guest to the latest 5.2 kernel (2.6.18-
92.1.13.el5xen) and got a kernel error on reboot:
powernow-k8: BIOS error - no PSB or ACPI _PSS objects
No problems seen yet.
I would think that the guest should not try to do any powernow stuff at
all. Has anyone else noticed this?

compaq r4000 /proc/cpuinfo reports 997 and should be 2400
Hi
I have a compaq R4000 with the 2.4GIG AMD 64 bit. 4000+ rated.
proc cpuinfo reports
cpu Mhz as 997.481
Do I have to run the 64 bit version to have things run correctly?
I just have the normal 4.2 loaded at this time.
The laptop seems slow for 4000+ as reflected by the cpu Mhz also.
Any thoughts on running the 32 bit version of 4.2 vs the 64 bit version
of 4.2?

Tyan Thunder K8SE S2892 Report
I had my eye on the Tyan dual-Opteron mobos for awhile. I tried to find
a posting *anywhere* sharing experiences with these boards under Linux.
No such luck. So placing myself under the heading "Where Angles Fear to
Tread," I went ahead and built a system anyway. Here's what I've learned.

CPU frequency scaling (SpeedStep and PowerNow)
Hello,
I have a new laptop (Core duo 2) and I plan to run Xen on it (using
Windows in a DomU). The laptop won''t be connected to a power plug all the
time. So it would be nice to have the possibility to set the CPU frequency
to a lower value to save some power. I only found the patch by Matt Yourst

Status of frequency scaling
Hi!
I would like to know the status of the frequency scaling in XEN. I found
a web site saying that XEN doesn’t work with frequency scaling, at the
other hand I found some fixes for powernow-k8 to get rid of some
messages.
I have an AMD64. powerno-k8 works find with non-XEN kernels, but with
XEN-kernels I get the error:

cpufreq support status
Could anyone summarize what the support status of cpu frequency changes
is at present. I don''t seem to recall generic changes to the hpyervisor in
that respect, but the linux tree has fairly extensive changes to the
powernow-k8 driver (which would make sense to me only if all other cpufreq
drivers are fully supported now, too).
Thanks, Jan
