FreeBSD v8.1上的/proc/cpuinfo等效项是什么? [英] What is the equivalent of /proc/cpuinfo on FreeBSD v8.1?

问题描述

在FreeBSD v8.1上，Linux的/proc/cpuinfo等效于什么?我的应用程序读取/proc/cpuinfo并将信息保存在日志文件中，我该怎么做才能将类似的信息记录在FreeBSD上?

What is the equivalent of Linux's /proc/cpuinfo on FreeBSD v8.1? My application reads /proc/cpuinfo and saves the information in the log file, what could I do to get similar information logged on FreeBSD?

/proc/cpuinfo示例如下:

A sample /proc/cpuinfo looks like this:

processor   : 0
vendor_id   : GenuineIntel
cpu family  : 6
model       : 23

使用dmidecode命令:

# dmidecode -t processor -t cache
# dmidecode 3.0
Scanning /dev/mem for entry point.
SMBIOS 2.4 present.
