FreeBSD v8.1上的/proc/cpuinfo等价于什么?

freebsd introspection porting cpu linux

WilliamKF · 技术社区 · 15 年前

在FreeBSDV8.1上,Linux的/proc/cpuinfo是什么等价物?我的应用程序读取/proc/cpuinfo并将信息保存在日志文件中,如何才能在FreeBSD上获取类似的信息?

示例/proc/cpuinfo如下所示:

processor   : 0
vendor_id   : GenuineIntel
cpu family  : 6
model       : 23
model name  : Intel(R) Xeon(R) CPU           E5420  @ 2.50GHz

我不相信有什么比Linuxs更详细的了 /proc/cpuinfo . 观察 sysctl hw 和 /var/run/dmesg.boot . 大部分信息,如CPU速度和指令集,应该在那里的某处。

hw.* 删除的字段):

$ uname -sr
FreeBSD 4.10-RELEASE
$ grep -i cpu /var/run/dmesg.boot 
CPU: Pentium III/Pentium III Xeon/Celeron (448.97-MHz 686-class CPU)
$ /sbin/sysctl hw
hw.machine: i386
hw.model: Pentium III/Pentium III Xeon/Celeron
hw.ncpu: 1
hw.byteorder: 1234
hw.physmem: 665989120
hw.usermem: 604614656
hw.pagesize: 4096
hw.floatingpoint: 1
hw.machine_arch: i386
hw.aac.iosize_max: 65536
hw.an.an_dump: off
hw.an.an_cache_mode: dbm
hw.an.an_cache_mcastonly: 0
hw.an.an_cache_iponly: 1
hw.fxp_rnr: 0
hw.fxp_noflow: 0
hw.dc_quick: 1
hw.ste.rxsyncs: 0
hw.instruction_sse: 0
hw.availpages: 162432

(注意,在OpenBSD上,cpu速度可以在 hw.cpuspeed 而不是在dmesg中。)

只需添加到jleedevs注释,您可以使用 sysctl(3) CTL_HW 顶级名称:
