From ed9aed1c9d7dd340006f22b96e1ee4476582b874 Mon Sep 17 00:00:00 2001 From: Russ Cox Date: Thu, 17 Aug 2023 15:44:20 -0400 Subject: internal/sysinfo: implement CPUName on bsd systems sysctl machdep.cpu.brand_string seems to be standard across the BSDs. There does not seem to be a standard way to get the CPU frequency.
