Linux ARM cpuid / cpubrand C ++ [英] Linux ARM cpuid/cpubrand C++

问题描述

是否有人知道获取CPUID和品牌字符串的方法，甚至可能是功能，类似于Linux ARM中NEON的MMX / SSE等检测？



似乎缺少任何形式的__cpuid和cpuid.h也不存在 - 至少在我的发行版上（OpenSuSE12.3）



它'对我的项目来说并不重要，但仍然很有趣。

is anyone aware about a method to get CPUID and brand string, as well as maybe even features, similar to MMX/SSE etc. detection for NEON in Linux ARM?

It seems to lack any form of __cpuid and cpuid.h ain''t existing also - at least on my distro (OpenSuSE12.3)

It''s not vital for my project, but still interesting.

你没有说你正在处理哪个ARM，但是Raspberry Pi（和其他人）用命令行告诉你CPU ID和其他信息

You didn''t say which ARM you are dealing with, but the Raspberry Pi (and others) tell you the CPU ID and other info with command line

cat /proc/cpuinfo

您可以在C / C ++中使用system（）调用。

which you can use from C/C++ with a system() call.

Linux ARM ，而不是x86。 ARM没有答案。我很高兴它会如此简单：）

Linux ARM, not x86. There are no answers for ARM. I''d be happy it would have been so easy :)
