Pinned topic Why powerpc doesn't support BogoMIPS ?

‏2011-10-27T10:19:38Z |
Hi,

Why doesn't powerpc support BogoMIPS in Linux Kernel?

BogoMIPS function is not in Linux Kernel source for powerpc.
And there isn't even any option like CONFIG_GENERIC_CALIBRATE_DELAY which enables BogoMIPS to work.

If I force to enable the CONFIG_GENERIC_CALIBRATE_DELAY option in powerpc, would that work properly?

or, how can I measure MIPS on powerpc?
