Extend guest channel and sample apps to query CPU frequencies. Please note that these changes depends on (http://patches.dpdk.org/project/dpdk/list/?series=6568) which should be applied first.
This feature is disabled by default, and must be explicitly enabled so that queries from guests are allowed: vmpower> set_query ubuntu3 enable Then the guest can query the set frequency for one or all cores: vmpower(guest)> query_cpu_freq all Frequency of [0] vcore is 2300000. Frequency of [1] vcore is 2300000. Frequency of [2] vcore is 2300000. Frequency of [3] vcore is 2300000. Frequency of [4] vcore is 2300000. Frequency of [5] vcore is 2300000. Frequency of [6] vcore is 2300000. Frequency of [7] vcore is 2300000. --- v2: * replaced strcpy() with strlcpy() Marcin Hajkowski (4): 1/4 power: extend guest channel for query freq 2/4 power: process cpu freq query 3/4 power: add mechanism to disable queries 4/4 power: add cmd to query CPU freq
