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 help me by giving me some hints? I''ve read many websites and papers and coded many things. I''m glade to get the sysfs file. With "sysfs_crea...

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

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. Does anyone have any solution to this? Thanks. - Hui _______________________________________________ Xe...

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...

Hi, Is there any documentation on enabling hypervisor support for both C and P-state control?

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 someone can add info to the INTEL_IDLE help text in the kernel configuration...
