To my surprise, c/s 8888 enables CPU_FREQ for x86-64 rather than disabling it for i386. Did anyone at your end actually test that if enabled this at least builds properly now? Not to mention that of course this also should work... If I remember right, the main reason for posting a patch to disable it on 32-bits (similar to how it was on 64-bits before) was that there were some missing symbols, and

But >my question was how this works when CPU_FREQ is configured off >in the kernel, but Xen is (told to [? - see below]) >control(ling) cpufreq. My answer was to xen controlled cpufreq. As I said below, xen cmd line option and dom0 CONFIG_CPU_FREQ are two conditions to enable xen controlled cpufreq. When FREQCTL_xen is set, cpufreq driver/governor within xen is enabled, which however doesn''t start working until someone (dom0) notifies xen about processor freq info. When dom0 CPU_FREQ is enabled, extcnl logic then attempts to parse...

...These are the latest versions of the Xen and the xen-ified linux kernel. I didn''t modify these sources, however I modified the config files. I made changes in config file to enable cpu frequency scaling support in the downloaded kernel. To activate cpu frequency scaling you need to enable CONFIG_CPU_FREQ in dom0''s config file. The original kernel do not provide a config file so I used a existing config file from my working linux (I have OpenSUSE 11 working on my machine with linux-2.6.25.5 kernel) and copied it as .config file in the source tree and then ran the make linux-2.6-xen-config C...

Hello, The following patches are a solution to a problem we have encountered when using the Xen hypervisor: - Need Pxx/Cxx states to save on power consumption when using Xen (we do want those datacenters to consume less power!), - Also need to figure out the Turbo mode so that the scheduler can properly boost a core for CPU bound guests. In essence the Xen hypervisor requires that

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
