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).

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. This patch fixes the following compilation error by defining stubs. This patch is just band aid patch until those functions are implemented later. > .../xen/drivers/built_in.o: In

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 ! On an 8-node cluster, one of the node did a kernel panic. The only bit of information I have is on a ssh console I had open, which said : Message from syslogd at node108 at Dec 14 19:00:15 ... kernel:------------[ cut here ]------------ Message from syslogd at node108 at Dec 14 19:00:15 ... kernel:invalid opcode: 0000 [#1] SMP Message from syslogd at node108 at Dec 14 19:00:15 ...

Hi, This is just to report about the "alignment check: 0000 [#1] SMP" kernel messages in one of my build system (domU) running Scientific Linux 6.1. I am compiling/rpm package for sbcl (http://sbcl.sourceforge.net/) in my build system (domU) and hit the following kernel messages although the domU in question still running and compilation still in progress. I have done some searching

Hello I have an active-active DRBD cluster using OCFS2 as the filesystem on the drbd devices. I started getting a "general protection fault error" when trying to mount any one of the ocfs2 volumes I have, even when running mount on a single node, with no mounted FSs on the other node. The kernel trace follows at the bottom of this message. Does anyone know what could have been

Hi, I recently installed Xen on my AMD64 for my first time and so far, everything seems to work pretty fine. :-) I tried to enable cpu frequency support.

Hello, I have a new laptop (Core duo 2) and I plan to run Xen on it (using Windows in a DomU). The laptop won''t be connected to a power plug all the time. So it would be nice to have the possibility to set the CPU frequency to a lower value to save some power. I only found the patch by Matt Yourst for AMD k8 processors
