/proc/cpuinfo
doesn't show CPU frequency at all.
I built the kernel on my own. Did I miss some kernel configuration?
pi@raspberrypi ~ $ cat /proc/cpuinfo

1In case you're interested, see
arch/mips/kernel/proc.c
in the kernel source. This answer is right: there's no code there to print the CPU frequency. – Flup – 2014-03-28T10:07:36.527I found BogoMIPS at @daniel-b shows above but not mine. Is this expected behavior too? – Younggun Kim – 2014-03-28T11:45:38.640
Yes, the whole output is architecture-dependent. The processor ID is probably the only universally present field. My router's architecture is MIPS, while your Raspberry Pi's architecture is ARM. – Daniel B – 2014-03-28T11:59:38.030
