在5.3的机器上，vmstat 1 2，cpu idle值可以正确得到
System Configuration: lcpu=8 mem=7808MB
kthr memory page faults cpu
----- ----------- ------------------------ ------------ -----------
r b avm fre re pi po fr sr cy in sy cs us sy id wa
0 0 998515 882178 0 0 0 0 0 0 10 422 257 0 0 99 0
0 0 998515 882178 0 0 0 0 0 0 20 581 245 0 0 99 0
但在6.1机器上vmstat 1 2的结果确如下
LYH40889B configuration: @lcpu=4 @mem=18432MB @ent=2.00
kthr memory page faults cpu
----- ----------- ------------------------ ------------ -----------------------

manual了一把，发现一个-@选项
-@ WparName
Reports the Virtual Memory activity of a workload partition:
* The -@ ALL option indicates that the report pertains to the system and global environment, in addition
to all of the workload partitions in the system. Note: The values that are system-wide statistics are
marked with dash sign (-) against the WPAR section.
* The [email=-@WparName]-@WparName[/email] option indicates that the activity is only for that workload partition. The system-wide
statistics are marked with the at sign (@). Note: Do not use the -@ option with any combination of the
-i option.
执行命令vmstat -@ 1 2，cpuidle可以被获取了，不太明白P6机型做了什么修改，workload partition是啥东东？
