The quilt patch titled Subject: cpufreq: powerpc: add missing MODULE_DESCRIPTION() macros has been removed from the -mm tree. Its filename was cpufreq-powerpc-add-missing-module_description-macros.patch This patch was dropped because it was merged into mainline or a subsystem tree -------------------------------------------------...

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 ------------ # modprob...

The patch titled Subject: cpufreq: powerpc: add missing MODULE_DESCRIPTION() macros has been added to the -mm mm-nonmm-unstable branch.

Currently xen-unstable.hg is broken on ia64 and it should be fixed by Yu''s patch. However he is off this week, so I''m sending the workaround patch. [IA64] Compilation fix to cpufreq stuff.

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_do...

...line capacity, which is 320000bit), but as soon as tc is enabled again, the upload speed drops again to 75-80kbit. There is no other traffic on the device, really, it''s just like if the htb couldn''t queue packets fast enough :??? I''ve thought that the culprit may be cpufreq. I have cpufreq scaling activated, and cpufreq reduces the clock speed from 1800MHz to 1000MHz when the processor is idle. This is more or less the same amount that I "lose" in the rate. May this be the problem? How to fix without deactivating cpufreq? I''m using htb+sqf, and...

Hej folks, I''ve been trying to get a new machine up and running with the latest Xen for a while on a Slackware64 (current) machine. After installing Xen from source and building a new kernel with all xen options enabled I haven''t been able to get the machine to behave. The machine is a brand new dual opteron 6212 on a Supermicro H8DGi board with 64G ECC memory. Running a stock

...a little) I find it rather odd (fragile) that the who-is-in-charge information gets propagated via a command line option rather than through the startup info. I think this should be adjusted before 3.3 gets frozen. Besides that I continue to wonder what significance the support for Dom0-controlled cpufreq handling has now that Xen has the ability to handle that. I ask this not the least because so far we disabled the CPU_FREQ config option in our kernels, partly because of the unknown status of all of the different low level drivers (powernow-k8 supposedly works, acpi-cpufreq apparently might work,...

These two patches provide the neccessary infrastructure changes for the processor-passthru driver [www.spinics.net/lists/linux-acpi/msg34655.html] to properly function. The first one is quite easy - we just modprobe the processor-passthru driver. The second allows it to work under AMD machines by exposing the PM RDMSR to dom0. It has been tested with 2.6.32 kernel as well to make sure it does

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 not getting cleared is benign)....

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).

struct cpufreq_policy, including a cpumask_t member, gets copied in cpufreq_limit_change(), cpufreq_add_cpu(), set_cpufreq_gov(), and set_cpufreq_para(). Make the member a cpumask_var_t, thus reducing the amount of data needing copying (particularly with large NR_CPUS). Signed-off-by: Jan Beulich <jbeulich@su...

Hi, I am trying to use the cpufreq driver and was unable to find the same on my xen kernel.

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.
