Can not modprobe acpi-cpufreq.ko in CentOS 5.2
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...

[PATCH] [IA64] Compilation fix to cpufreq stuff.
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.

[PATCH] cpufreq.c: shut up compiler about cpufreq_dom
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...

HTB doesn''t give me the promised rate: cpufreq?
...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...

Xen 4.3.1 / Linux 3.12 panic
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.

cpufreq info propagation
...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,...

[PATCH 0 of 2] [RFC] Patches to work with processor-passthru driver (v1).
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

[PATCH] cpufreq: error path fixes
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)....

cpufreq support status
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).

[PATCH 07/12] cpufreq: allocate CPU masks dynamically
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...

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.
