similar to: xenpm hypercalls support in latest kernels?

Hi, i read the xenpm wiki page, but i cannot use the "p-states". xenpm shows: xenpm cpu id : 0 total C-states : 2 idle time(ms) : 1776034 C0 : transition [00000000000000000000] residency [00000000000000000000 ms] C1 : transition [00000000000000260278] residency

Hi, All, I have some problem of using dvfs in Xen 3.4.1 and 2.6.18 kernel. I enabled Speed option in BIOS and add "cpufreq=xen" in the grub file. But when I entered my dom0 and type "xenpm get-cpufreq-XXX" (any xenpm argument), it returns "[CPU0] failed to get CPU P state". I am wondering if I should enable some feature of 2.6.18 during the kernel configuration.

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.

Hello, I''ve tried to get the CPUFreq plugin of collectd running in dom0. But I mentioned that it isn''t so easy to get a file in sysfs on the rigth place. I know that the value has to come from hypervisor and I''ve seen the code in xenpm. The only value I need is "/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq" which would create cpufreq.c. Can anyone

Currently, enable/disable turbo mode on AMD is broken: $ xenpm enable-turbo-mode 0 <-- works and proper CPU MSR bit is set $ xenpm enable-turbo-mode 1 <-- silently broken, MSR bit not set Since ->turbo is per policy, when user requests to enable/disable turbo mode, we need to set the bit in all of the ->cpus that this policy affects. --- xen/arch/x86/acpi/cpufreq/powernow.c | 2

- use consistent error values (stop mixing of [positive] errno values with literal -E... ones) - properly format output - don''t use leading zeros in decimal output - move printing of average frequency into P-state conditional (rather than a C-state one) - don''t print some C-state related info when CPU idle management is disabled in the hypervisor - use calloc() for array

Hi everyone, When I set CONFIG_ACPI_PROCESSOR, CONFIG_CPU_IDLE and CONFIG_INTEL_IDLE to y then I cannot boot Xen; there is a crash. If I turn CONFIG_INTEL_IDLE off then the boot goes well and, after dom0 has booted, xenpm works and gives some sane output, see below. I have tested this with kernels 3.2 to 3.4.6. Is it impossible to use INTEL_IDLE with Xen? If this is a known issue then maybe

Hi, Is there any documentation on enabling hypervisor support for both C and P-state control? On xen-unstable and linux-2.6.18-xen.hg, if I enable cpuidle=1 on the xen command line and then run xenpm, I will get output for C-states (shown below) but it complains that "Xen cpufreq is not enabled!" cpu id : 0 total C-states : 2 idle time(ms) : 73264 C0

I do not seem to be able to get any where with the power management functions. I have had a look at the xenpm Wiki page, but it hasn''t helped. Its probably something completely obvious, but I can''t see it. I running Xen 3.4.0 on Centos 5.3 x86_64 using the gitco RPMs on an Intel S5000PSL motherboard with 2 x Xeon 5410s.

    Hello all,     I develop a project based on Clang where I need to read all symbols from a library.

Hi, i''m not sure if i understood the new acpi xen cpufreq driver - here''s the output when loading xen_acpi_processor module in linux 3.4: dom0 dmesg: [ 32.728151] xen-acpi-processor: (CX): Hypervisor error (-22) for ACPI CPU8 [ 32.728156] xen-acpi-processor: (CX): Hypervisor error (-22) for ACPI CPU9 [ 32.728160] xen-acpi-processor: (CX): Hypervisor error (-22) for

Specifically, what values are or aren''t accepted as CPU identifier, and how the values get interpreted should be consistent across sub-commands (intended behavior now: non-negative values are okay, and along with omitting the argument, specifying "all" will also be accepted). For error handling, error messages should get consistently issued to stderr, and the tool should now

Hi, If we want to use ACPI power saving(Cx/Px), how do we use them? I tried to turn CONFIG_xxxx of cpufreq on with linux-2.6.18-xen.hg, but I couldn''t turn them on. Also xenpm said the following error. # xenpm get-cpuidle-states Xen cpuidle is not enabled! # xenpm get-cpufreq-states Xen cpufreq is not enabled! What should I do? If there are some good documents, please tell me. Best

Hi! Attached patch makes xen-tools and stubdom-dm going independent from hardcoded pathes. It is no possible to install into /usr/local or any other non-default directory and use it out-of-the box. This allows us to have different Xen versions in different directories, simplifies packaging for distributions. It also finds ''hvmloader'' and

The log snippet doesn''t have the detail in it - have a look in /var/log/SMlog - you might find something more useful in there.

Hello everyone. I am looking for a E1 PRI card which supports network side signaling not CPE. The main idea is to connect an plain old E1 compliant PBX which doesn't have an VoIP module to the newly created VoIP infrastructure. Could we use a Digium TE122P or something other to resolve this situation? Thanks in advance. Dimitar -------------- next part -------------- An HTML attachment was

Hello everyone. I want to migrate an old PBX which uses the ?1-PRI from one Telecom to VoIP by transparently moving the numbers one by one. I mean that the numbers that the PBX handle must be transparently moved from one operator to another. The old connection to the PBX is ?1-PRI and we must preserve that because no one knows how to configure this PBX. So my idea is to connect a PC with 2
