similar to: acpi: fan running and cpufreq always at minimum on centrino

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; 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

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

Dear all, The cpufreq modules have been distributed in Centos. But recently, I met a problem when I tried to test the power-related applications. The module can not be modprobed in kernel notwithstanding releated with Centos distribution. The messgae thrown out is: ------------- dump of screen ------------ # modprobe p4-clockmod.ko FATAL: Module p4_clockmod.ko not found

Hi Konrad, The devel/acpi-cpufreq.v4 branch doesn''t seem to be merged into your linux-next branch yet. Is it still targeted for 3.3 ? I have been running your testing branch with linus his tree pulled on top of that, and it ran stable for me. Thx for all the hard work upstreaming everything ! -- Sander

Hi, Does Xen provide support for CPU frequency scaling? If there exists such support, from which version they support it? Otherwise what problems do exist in support frequency scaling in Xen?

Dear All, i'm working on this Centos6.5 laptop, fully updated *# uname -a** **Linux jvermeulen.ict 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux* It's an Acer Aspire E1-571. I can't get the Intel Centrino N 6235 to work. I've used this card on several different types of laptops and never had any trouble. I think I have the packages

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.

With CentOS 7.2 a laptop wireless card is recognized in dmesg, but nonfunctional. Toggling the hardware wifi switch causes the Bluetooth icon to appear and disappear. The network configuration window shows the Wireless tab greyed out. Rebooting with the bluetooth enabled does not help. It appears the appropriate driver is iwlwifi, which is what works in Fedora and appears to be available and

Some versions of GCC are too stupid to figure out that cpufreq_dom is only used if !!domexist and always set in that case, and complain that it may be used uninitialised. (In general it is IMO better to avoid these kind of flag variables; I would prefer structures like for (...) { cpufreq_dom = dom; if (...) goto cpufreq_dom_found; } cpufreq_dom = 0; cpufreq_dom_found: but on

With my OQO, I get the following message when I try to suspend: cpufreq: suspend failed to assert current frequency is what timing core thinks it is.

Hi all :) I''ve been using a tc setup for almost two years, but at some point (probably when I switched to kernel 2.6.x, but I''m not sure) it has started making something very weird. For a certain class, the rate is 125000bit and the ceil is 270000bit, but the fastest rate I get is about 75-80000bit, instead of the "promised" 125000, *with no other traffic in

Hi, I am trying to use the cpufreq driver and was unable to find the same on my xen kernel. I am currently running the folloing kernel: # uname -a Linux mbr-Dom0-3 2.6.18.8-xen #1 SMP Wed Jan 28 10:27:04 IST 2009 x86_64 x86_64 x86_64 GNU/Linux I read in certain places that some versions of Xen donot support cpufreq. But the information was not too clear. Could someone kindly tell me if cpufreq

This fixes an actual bug (failure to exit from a function after an allocation failure), an inconsistency (not removing the cpufreq_dom list member upon failure), and a latent bug (not clearing the current governor upon governor initialization failure when there was no old one; latent because the only current code path leading to this situation frees the policy upon failure and hence the governor

Oh, thanks, Niraj. I overlooked this initially, because this code is not implemented in waldi 3.1-2 kernel, but only in 3.3-1. I''ll check it out tonight, as booting a new kernel per remote is a bit too dangerous. This would be exactly what I need. BR, Carsten.
