Tyan Thunder K8SE S2892 Report
...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&q...

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? Jerry

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

Powernow-k8 support

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

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).

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?

[PATCH][Retry 1] 1/4: cpufreq/PowerNow! in Xen: Xen timer 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 multipli...

cpu frequency scaling in domUs
Hi, I''ve recently installed xen-3.2.1 on my AMD Sempron(tm) machine. It runs gentoo 2.6.21 as dom0 and cpu frequency scaling works in dom0. But inside a domU, cpu frequency scaling is not working. By checking the boot log in domU I found that domU is unable to load the powernow driver: "powernow-k8: BIOS error - no PSB or ACPI _PSS objects" I wonder if it is possible to have cpu frequency scaling support inside domUs? -- Vahid _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.c...
