Hi all.
I want to get info about cpu without parsing /var/run/dmesg.boot, is
it possible?
I'm porting ohai (https://github.com/chef/ohai/pull/626/files#r41601905).
You can use sysctl to extract information, e.g.:
sysctl hw.cpu_topology.tree
hw.cpu_topology.tree:
\-PACKAGE MEMBERS: cpus(0-7)
\-CHIP ID 0: cpus(0-7)
|-CORE ID 0: cpus(0, 4)
| |-THREAD ID 0: cpus(0)
| \-THREAD ID 1: cpus(4)
|-CORE ID 1: cpus(1, 5)
| |-THREAD ID 0: cpus(1)
| \-THREAD ID 1: cpus(5)
|-CORE ID 2: cpus(2, 6)
| |-THREAD ID 0: cpus(2)
| \-THREAD ID 1: cpus(6)
\-CORE ID 3: cpus(3, 7)
|-THREAD ID 0: cpus(3)
\-THREAD ID 1: cpus(7)
What information you are looking for exactly?
