Linux ARM cpuid/cpubrand C++

Question

See more:

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.

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

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

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

in this case its a Pandaboard, using an OMAP4430, CortexA9 Dual Core. I am aware about the cpuinfo, indeed it gives out basically all info I want to have, but I was interested in reading it out myself, just like for x86. As said, it's not vital, just curiosity since I can't imagine there is no way, but no one seems to know it.

You could always try reading the technical documentation for the board and the chipset.

Did that already too, but I wasn't able to find whats needed so far. That's why I am digging for a general solution here now.
