Hi, is there a patch for xen-source-2.6.20-r3 for use cpufreq on turion64? I''m using xen-sources of gentoo portage. Thanks in advance. Bye Ge@@ru _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

So when traveling I have to boot non XEN limiting me to dom0. It shouldn''t be too hard to write a little application that will scale frequency depending on the sum of cpu usage of all domains. The info is shown in xentop so it should be simple of sampling that once every X second and sclaing for it. But even a simple "make it slow" option would be just fine.

A dom0 with cpufreq support enabled can use the performance, powersave, and userspace governors to change frequency. You''ll need to build the latest repository of xen-unstable.hg and linux-2.6.18.hg with the cpufreq build config options enabled, and pass "cpufreq" on the Xen command line. Power management should come up normally, and running `echo "powersave" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor` should force the system to minimum power. The same command with "performance" should set it to maximum power. The same command with "userspace" will create a /sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed file, and writing a frequency value to that will cause the system to move to the nearest supported frequency to that value. A usermode daemon like cpuspeed (http://carlthompson.net/Software/CPUSpeed) can be modified to use the Xen getcpuinfo sysctl to read the Xen usage values and write to the scaling_setspeed file, though I haven''t had time to do that yet. The ondemand governor won''t be supported unless getcpuinfo becomes a platform op hypercall. Rik, what''s the status on that? -Mark Langsdorf Operating System Research Center AMD _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

No ACPI objects means no information on the pstates. Do you get PowerNow! support on a native version 2.6.21+ kernel? If not, you need to update your BIOS to something that supports pstates (or possibly you have one of the rare Turions that doesn''t support more than 1 pstate, but I doubt that). If 2.6.21+ native works, check to see if 2.6.18 native works. If it doesn''t, then there was a change to the ACPI interpreter to support your laptop that will need to be backported. If 2.6.18 native works, then there''s a difference between the Xen ACPI interpreter and the native mode interpreter that will need to be ported to Xen. -Mark Langsdorf Operating System Research Center AMD _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
My current kernel version 2.6.22 (as previous versions 2.6.21, 2.6.20) native works fine. Probably, there is a difference (as you said me) between Xen ACPI Interpreter and the native mode interpreter. I try also with xen-source-2.6.18 tree without xen support and in this case, cpufreq works fine. Only if i enable xen cpufreq doesn''t work.
