Booting High Speed
Hi All
Here:
$ cat /proc/cpuinfo
processor : 0
cpu : 7455, altivec supported
clock : 867MHz
revision : 3.2 (pvr 8001 0302)
bogomips : 865.18
machine : PowerBook3,5
motherboard : PowerBook3,5 MacRISC2 MacRISC Power Macintosh
detected as : 80 (PowerBook Titanium IV)
pmac flags : 0000000b
L2 cache : 256K unified
memory : 768MB
pmac-generation : NewWorld
seems my machine boots with only 667 MHZ:
# dmesg | grep Low
Low: 667 Mhz, High: 867 Mhz, Boot: 667 Mhz
Some values from the config from the kernel where this is happening on:
$ grep -i freq /boot/config-2.6.8-powerpc
CONFIG_CPU_FREQ=y
# CONFIG_CPU_FREQ_PROC_INTF is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
# CONFIG_CPU_FREQ_24_API is not set
CONFIG_CPU_FREQ_PMAC=y
CONFIG_CPU_FREQ_TABLE=y
# Wireless 802.11 Frequency Hopping cards support
Actually I thought with
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
full speed would be the default when booting: What did I miss?
Where's the speed switch?
Anyone who knows how to turn on full speed/867 MHz while booting this
machine?
Thanks in anticipation
Best Regards
Wolfgang
