virt inclusion category: feature bugzilla: 46853 CVE: NA This patch export cpu time related items to vcpu_stat. Contain: steal, st_max, utime, stime, gtime The definitions of these items are: steal: cpu time VCPU waits for PCPU while it is servicing another VCPU st_max: max scheduling delay utime: cpu time in userspace stime: cpu time in sys gtime: cpu time in guest Through these items, user can get many cpu usage info of vcpu, such as: CPU Usage of Guest = gtime_delta / delta_cputime CPU Usage of Hyp = (utime_delta - gtime_delta + stime_delta) / delta_cputime CPU Usage of Steal = steal_delta / delta_cputime Max Scheduling Delay = st_max Signed-off-by: Nliangpeng <liangpeng10@huawei.com> Signed-off-by: Nchenjiajun <chenjiajun8@huawei.com> Reviewed-by: NXiangyou Xie <xiexiangyou@huawei.com> Acked-by: NXie XiuQi <xiexiuqi@huawei.com> Signed-off-by: NChen Jun <chenjun102@huawei.com>
