similar to: powernow error in Xen VM with new kernel

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. After booting, I get the following message in Dom0-dmesg: powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.60.0) powernow-k8: BIOS error - no PSB or ACPI _PSS objects I tried to find answers in the mailing-list archive and

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

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 tried to enable cpu frequency

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

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

Hello, We have recently purchased two Supermicro servers, AS-1021M-T2RB (http://www.supermicro.com/Aplus/system/1U/1021/AS-1021M-T2RV.cfm), and have built them both with CentOS 5 operating system. They are identical, apart from the manufacturer of the disk drives. Kernel is: Linux version 2.6.18-8.1.6.el5 (mockbuild at builder6.centos.org) (gcc version 4.1.1 20070105 (Red Hat 4.1.1-52)) #1 SMP

Hello all, since upgrade to 6.3 (and kernel 2.6.32-279.x) it looks like only one core of the AMD Dualcore Opteron 1218 is functional. Reverting to previous kernel shows everything working as expected. I've filed a bug report here after failing to figure out if it is just a configuration problem: http://bugs.centos.org/view.php?id=5821 I can't find anything on the net that would

With the third generation Opteron parts, AMD switched to an architecturally defined interface for PowerNow! that uses different MSRs than previous versions. This patch brings the PowerNow! driver up to match the mainline Linux driver and provide support for all AMD parts that use or will use the architectural pstate interface. It also removes a WARN_ON statement in kernel/cpu.c that highlights a

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
