CPU Temprature
Hi;
While using xen-3.0.2 with 2.6.16.28 kernel CPU (Intel(R) Pentium(R) M
processor 1.73GHz) temprature is inreasing up to 104 C
(/proc/acpi/thermal_zone/THRM/trip_points reports 105 C is critical for CPU)
while idle or no domU working with very low system load, and if i
start to use domU, sometimes system freezes or reboots for heat.
But the same kernel just without Xen works normally and

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

[Discussion] User controls for PowerManagement
With some progress in PowerManagement support (there's a patch nearly done for
reading the P-tables, written mostly by xexaxo, derived from thunderbirds
nvclock, with 0x40 adjustments from myself) in my opinion it's time to think
about the user aspect of this.
My personal idea for GPU scaling was similar to that of CPU scaling in
appearance eventually. When you look at the cpufreq-applet

[PATCH 0 of 2] [RFC] Patches to work with processor-passthru driver (v1).
These two patches provide the neccessary infrastructure changes
for the processor-passthru driver [www.spinics.net/lists/linux-acpi/msg34655.html]
to properly function.
The first one is quite easy - we just modprobe the processor-passthru driver.
The second allows it to work under AMD machines by exposing the PM RDMSR
to dom0. It has been tested with 2.6.32 kernel as well to make sure it does

overheating Thinkpad X60s with 7.0-RC1
Hello everybody!
Since the update from 6.2-STABLE to 7.0 I'm encountering problems with the
temperature of my Thinkpad X60s. Under heavy load, e.g., make builworld or
compile gcc or... I get the following output in /var/log/messages:
Dec 29 01:53:13 delta1 root: WARNING: system temperature too high, shutting
down soon!

[PATCH] 1/2: cpufreq/PowerNow! in Xen: Time and platform changes
Enable cpufreq support in Xen for AMD Operton processors by:
1) Allowing the PowerNow! driver in dom0 to write to the PowerNow!
MSRs.
2) Adding the cpufreq notifier chain to time-xen.c in dom0.
On a frequency change, a platform hypercall is performed to
scale the frequency multiplier in the hypervisor.
3) Adding a platform hypercall to the hypervisor the scale
the frequency multiplier and reset

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

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.

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:
powernow-k8: Found 1 AMD Athlon(tm) 64 Processor 3400+ processors

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.

Hi,
I recently installed Xen on my AMD64 for my first time and so far,
everything seems to work pretty fine. :-)

Writing MSRs from Domain0
Hello,
I recently tried Xen 3.0.3-testing on my 2x Opteron-244 SMP machine.
Everything works well exept one detail, which is not unimportant to me:
the powernow-k8 driver fails to switch frequencies. A closer look on the
powernow-k8 source reveals, that some MSR write operations seem to be
without any effect. A rdmsr() before and after the wrmsr() call reveals
that no real change on the register

[PATCH V2 1/2] cpufreq, xenpm: fix cpufreq and xenpm mismatch
Currently cpufreq and xenpm are out of sync. Fix cpufreq reporting of
if turbo mode is enabled or not. Fix xenpm to not decode for tristate,
but a boolean.
