RE: BogoMIPS no longer supported on PowerPC?

Ok, I rephrase my question as is it no longer needed?  Sometimes people
may use this value as a rough estimation of CPU performance.  There are
people even maintained a list of bogoMIPS of most CPUs.  Maybe it is
still needed for some legacy reasons.  I'm not very sure.  :)   At leave
we need to inform people who do look at this magic number and find it
amazingly low.

Best Regards,
Leo

What's there to be 'supported'? The only purpose of bogomips is
calibrating the delay loop, and that has changed now by using

timebase,

hence bogomips no longer have a purpose. There was even a patch to
remove it from /proc/cpuinfo but I'm not sure whether that got applied
or not.
