x86cpu

############################## Collect information on x86 CPU ##############################

Uses cpuid <https://en.wikipedia.org/wiki/CPUID>_ instruction to get information about CPU.

Queries OS as well as cpuid <https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#Operating_system_support>_ 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
