尽管在手册中已经描述了VMX Preemption Time的Specification,可是并不是所有处理器都支持这项功能,比如我的T2300就不支持,实验室的E8600也不行。 问了下Intel的人,回复是只有最新的Intel Core i7系列才开始支持。所以要用到这项特性的前一定要检查IA32_VMX_PROCBASED_CTLS (index 0x481) MSR寄存器的bit 38. 如果...
Hi, From what I understand, the VMX-preemption timer should only decrement when in VMX non-root operations. I have been trying to use it as a way to
