Problems with enabling hypervisor C and P-state control
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

[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).
