I know bogomips are kinda "bogus by definition", but I'll ask anyway, out of curiosity:--- ppc-cpuinfo.2.6.20-rc6 2007-01-27 12:33:00.000000000 +0000 +++ ppc-cpuinfo.2.6.21-rc4-git6 2007-03-24 16:25:26.000000000 +0000@@ -1,8 +1,8 @@ processor : 0 cpu : 7447A, altivec supported -clock : 1199.999997MHz +clock : 1199.999000MHz revision : 0.1 (pvr 8003 0101) -bogomips : 36.73 +bogomips : 73.47 timebase : 18432000 platform : PowerMac machine : PowerBook6,5It seems that with a more recent kernel, bogomips have doubled (both with CONFIG_HZ=1000, if this matters). How comes?
Not sure what the bogomips are about nowadays but they are irrelevant on most macs as we use the timebase for short delays. Ben.
