I just upgraded my iBook G4[1] to FreeBSD 9.1-prerelease.
Before the upgrade, dmesg showed this for the CPU:
cpu0: Motorola PowerPC 7447A revision 1.5, 713.92 MHz
cpu0: Features 9c000000<PPC32,ALTIVEC,FPU,MMU>
cpu0: HID0 8450c0bc<EMCP,TBEN,NAP,DPM,ICE,DCE,SGE,BTIC,LRSTK,FOLD,BHT>
The upgrade took a long time, so I could believe it was running at that speed.
And after the upgrade, it still shows this:
root@kg-ibook# uname -a
FreeBSD kg-ibook.kg4.no 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #0: Thu Jul 19 11:26:56 CEST 2012
root@kg-ibook.kg4.no:/usr/obj/usr/src/sys/GENERIC powerpc
root@kg-ibook# dmesg | grep cpu
cpu0: Motorola PowerPC 7447A revision 1.5, 713.92 MHz
cpu0: Features 9c000000<PPC32,ALTIVEC,FPU,MMU>
cpu0: HID0 8450c0bc<EMCP,TBEN,NAP,DPM,ICE,DCE,SGE,BTIC,LRSTK,FOLD,BHT>
cpulist0: <Open Firmware CPU Group> on nexus0
cpu0: <Open Firmware CPU> on cpulist0
dfs0: <Dynamic Frequency Switching> on cpu0
But the CPU in this thing is supposedly running at 1.42 GHz, so why is it showing the wrong speed?
Details, dmesg output and more at the FreeBSD page for this machine[2].
