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 powernow-k8: Found 2 Quad-Core AMD Opteron(tm) Processor 8350 processors (8 cpu cores) (version 2.20.00) powernow-k8: 0 : fid 0x0 gid 0x0 (2000 MHz) powernow-k8: 1 : fi...

...verything was recognized by the system, all three network ports, the Nvidia SATA controller and even the 3Ware controller. However, the boot messages showed: warning: many lost ticks. Your time source seems to be instable or some driver is hogging interrupts and several repeating messages: powernow-k8: error - out of sync... Also, /proc/cpuinfo showed each cpu as running at about 1004Mhz with about 900 bogomips. Not what I expected. I decided to press ahead and added a couple of drives the the 3Ware, created a unit, formatted it and began benchmarking the array. The "powernow" mes...

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?

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 ocurrs. An older PowerNow patch from this list emulates MSR...

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. Signed-off-by: Jan Beulich <jbeulich@suse.com> --- a/xen/arch/x86/acpi/cpufreq/powernow.c...

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

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 (version 2.00.00) powernow-k8: BIOS error - no PSB or ACPI _PSS objects This is normally a BIOS e...

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).

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?

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

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.

Hey all, Since moving a 4.3 x86-64 install from a single athlon64 to a new dual core AMD cpu it would appear that cool'n quiet is having trouble as is shown in the system logs; powernow-k8: ignoring illegal change in lo freq table-2 to 0x2 powernow-k8: transition frequency failed Any ideas ? Cheers, Brian.
