Cpufreq: prevent negative px resident time, add spinlock to avoid race Due to NOW() value may drift between different cpus, we add protection to prevent negative px resident time. Due to both cpufreq logic and xenpm may race accessing cpufreq_statistic_data, we add spinlock to avoid race.

Hi, Is there any documentation on enabling hypervisor support for both C and P-state control? On xen-unstable and linux-2.6.18-xen.hg, if I enable cpuidle=1 on the xen command line and then run xenpm, I will get output for C-states (shown below) but it complains that "Xen cpufreq is not enabled!" cpu id : 0 total C-states : 2 idle time(ms) : 73264 C0

Set userspace governor as default, which stays same effect as when cpufreq in xen is not enabled. As a result, enable cpufreq in xen by default to avoid reboot to activate cpufreq. Now it''s always on but w/o performance impact if user doesn''t tempt to change governor. We also add some warning info for debug. Signed-off-by: Liu, Jinsong <jinsong.liu@intel.com>

Hi, Jeremy Since now the pv_ops domain0 is approaching, we are considering to port the dom0 power management related code, or more specifically, the Cx/Px ACPI info parsing code, to pv_ops domain0 tree, so that people can utilize Xen power management capability (Cx/PX) under pv_ops domain0.
