[PATCH V2 1/2] cpufreq, xenpm: fix cpufreq and xenpm mismatch
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.

cpu frequency scaling in xen 3.3.1
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

Kernel crash with acpi_processor, cpu_idle and intel_idle =y
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

[PATCH] xenpm: make argument parsing and error handling more consistent
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

Using collectd: CPUFreq in dom0
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

Problems with enabling hypervisor C and P-state control
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

DVFS, xenpm in 3.4.1 and linux 2.6.18
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.

xenpm hypercalls support in latest kernels?
Does anyone know what is the latest version of dom0-kernel, that supports fully xenpm hypercalls? I tried from 3.0 to 3.3 with xen-4.1.3, but none of them has xenpm working. On the other hand native kernel cpufreq is OK with all of them. My CPU is Xeon family 6 on PowerEdge 1950 III box. Regards, Dimitar Kazakov

More Coverity-reported issues.
Another bundle of issues from Coverity triage. The first one is in x86/mm, and looks scarier than it is. The others are all in xen/drivers and AFAICT are pretty minor. Cheers, Tim.

[PATCH] tools/stubdom: get rid of hardcoded pathes
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

Problems with power management
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.

A way to list only variables or functions?
I am curious if there is any way to list only variables or functions in current environment, rather than listing all objects? Thanks. -- Daehyok Shin (Peter) Geography Department Univ. of North Carolina-Chapel Hill
