Measure mwait of cpu
WebIf guest executes MWAIT without vmexit, how to check the register? That way any time a guest gets naturally aborted while in mwait, it will only reenter mwait when an event actually occured. While the guest is normally running (and nobody else wants to run on the host), we just stay in guest context, but with a sleeping CPU. WebMar 24, 2024 · On Windows, open the System page to view the CPU clock speed. On Mac, open the About This Mac page to see the CPU speed.
