Now, this is silly!
Pure Python library for accessing information about x86 processors by querying the CPUID instruction. Well, not exactly pure Python...
It works by allocating a small piece of virtual memory, copying a raw x86 function to that memory, giving the memory execute permissions and then calling the memory as a function. The injected function executes the CPUID instruction and copies the result back to a ctypes.Structure where is can be read by Python.
It should work fine on both 32 and 64 bit versions of Windows and Linux running x86 processors. Apple OS X and other BSD systems should also work, not tested though...
For poops and giggles. Plus, having access to a low-level feature without having to compile a C wrapper is pretty neat.
Getting info with eax=0:
import cpuid
q = cpuid.CPUID()
eax, ebx, ecx, edx = q(0)
