How can we get the CPU information from driver code?

nish_antnish_ant Member Posts: 2

If a WDF/NDIS driver needs to know the processor information such as CPU Family/Model/Stepping, how one can query this from driver code?
In WinDbg there is a command !cpuinfo to get these data, trying to get same info from driver.

    That's all available from the __cpuid intrinsic function, which executes the cpuid instruction directly.

    However, why on earth would a driver ever need to care about such things?
