X-BeenThere: freebsd-ppc@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Porting FreeBSD to the PowerPC List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 19 Jul 2012 11:55:48 -0000 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 cpu0: HID0 8450c0bc 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 cpu0: HID0 8450c0bc cpulist0: on nexus0 cpu0: on cpulist0 dfs0: 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].
