similar to: CPU frequency scaling (SpeedStep and PowerNow)

Package: xen-hypervisor-4.1-amd64 Version: 4.1.3-3 Severity: normal Forwarded: http://bugzilla.xen.org/bugzilla/show_bug.cgi?id=1789 Dear Debian Xen Team, after an upgrade from Squeeze to Wheezy I see about ten of these per second filling my system log (about 8 MB/h): Nov 23 00:15:37 acromantula kernel: [ 462.544193] powernow-k8: fid trans failed, fid 0x2, curr 0x0 Nov 23 00:15:37 acromantula

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

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

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

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 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

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? Kai -- Kai Sch?tzl, Berlin, Germany Get your web at Conactive Internet Services:

Hello I'm building a router/proxy/firewall, the default governor is ondemand, but for this application, what governor is best suited? (for example conservative?) Thanks at all! Best regards

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

Hi. I''m working on xen 4.1 from gitco, is not a list to ask let me know please. Well I got a motherboard from biostar A780L3L 6.0v with a AMD Athlon II 640 3Ghz. This one got 4 cores, what took my attention is this message: powernow-k8: Found 1 virtualized processors powernow-k8: 0 : fid 0x0 gid 0x0 (3000 MHz) powernow-k8: 1 : fid 0x0 gid 0x0 (2300 MHz)

Hi, I have a v2000 compaq laptop. The realtek network and USB on this machine was not working. After adding to grub.conf "acpi=off apci=off noacpi noapic" the v2000 realtek started working and the USB worked fine... Fantastic!

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

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

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 ?
