搞了一个软件ＭＳ 避免延时。
rdmsr latency for IA32_PQR_MSR is very high (~250
cycles) this software cache is necessary to avoid reading the MSR to
compare the current CLOSid value.
- MSR write is only done when there is a task with different Closid is
scheduled on the CPU. Typically if the task groups are bound to be
scheduled on a set of CPUs, the number of MSR writes is greatly
reduced.
