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

I thought you were saying it matters - as it should be done around the same time as cpufreq drivers were loaded? .. snip.. >> For a), this would mean some

Hi, I get a crash in dict if I use multiple map sections. Each one of them works fine by their own. I managed to convince dovecot to create dump files to debug this, but I can't figure out how to do the same for dict. How can I do this? Anyway, perhaps someone already know's what's wrong by looking at what I do in the sql dict configuration. Mar 9 02:27:52 xxx dovecot: dict:

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.

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.

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

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

Hello ! Does anybody know how to build and use cpufreq support that should be in 3.2 since -unstable time ?

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

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 all :) I''ve tested this and having a cpufreq that slows down the CPU affects the rate of HTB. My ondemand cpufreq governor scales down the CPU frequency about 40% and this is more or less the slowdown the rate suffers, 40%. Any known way of dealing with this without having to disable cpufreq? Thanks in advance :) Ra?l N??ez de Arenas Coronado -- Linux Registered

Now that I finally got around to update our sources, I had a closer look at those changes, and apart from stylistic issues on the Linux side (part of which I may have asked for, but the result was somewhat overdone so the code is hardly legible now - I''ve got a patch queued to streamline this a little) I find it rather odd (fragile) that the who-is-in-charge information gets propagated

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

Hi, I noticed that the fan of my centrino is very often running since I use Xen (the load is very low still). Also the cpufreq is always at 600MHz (the max is 1500MHz), regardless of what of what heavy computations I do (e.g. calculating md5sums). I heard that it is not possible to run a cpufreq scheduler like powernowd or cpufreqd, but would it be possible to set the cpu frequency at least

Hi, I try to build experimental networks with Xen and stumbled over the same problem that has been described quite well by Mark Doll in his posting "xen_net: Failed to connect all virtual interfaces: err=-100" here: http://lists.xensource.com/archives/html/xen-users/2005-04/msg00447.html As it was still present in 2.0.6, I tried 3.0-devel and found NR_PIRQS and NR_DYNIRQS had been
