Hi,
I need to port win32 app. on AMD64 for which I need
to remove inline assembly(not supported on 64-bit) using
intrinsic function. Inline assembly involves set of "mov" instructions
to detect the processor type using CPUID instruction. Here is the
inline assembly

mov eax, 0x80000000
CPUID
mov value, eax.

i am using intrinsic function void __cpuid(
int* CPUInfo,
int InfoType
);

whihc requires second param to be infotype. So, Should I give
0x80000000 as the value of Infotype???

Can anyone tell me what should be the equivalent code for above
mentioned inline assembly using __cpuid intrinsic.

thanks
xyz

The real question is what do you think you need in the way of data from that
instruction in a driver? Will ExIsProcessorFeaturePresent do enough for
you?
