Collect information on x86 CPU

Uses cpuid instruction to get information about CPU.

Queries OS as well as cpuid to see if the OS / CPU supports AVX instructions.

Quickstart

>>> from x86cpu import info
>>> print(info.model_display, info.family_display)
(69, 6)
>>> print(info.vendor)
GenuineIntel
>>> print(info.brand)
'Intel(R) Core(TM) i5-4250U CPU @ 1.30GHz'

You can run the cpuid command directly. The argument to cpuid goes into the EAX register before calling the CPUID instruction:

>>> from x86cpu import cpuid
>>> cpuid(1)
{'eax': 263761L, 'ebx': 17827840L, 'ecx': 2147154879L, 'edx': 3219913727L}

Some CPUID commands also care about the value in the ECX register. You can set this with a second optional argument to cpuid:

>>> cpuid(13, 1)
{'eax': 1, 'ebx': 0, 'ecx': 0, 'edx': 0}

The package installs a command line tool x86report giving output like this:

$ x86report
