Hi people,
My processor is a sempron 3100+ :
cat /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 44
model name : Mobile AMD Sempron(tm) 3100+
stepping : 2
cpu MHz : 800.000
cache size : 256 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext fxsr_opt
3dnowext 3dnow pni lahf_lm ts fid vid ttp tm stc
bogomips : 1598.67
I'm using powernow-k8 module to scale my processor on userspace demand.
The frequence of my CPU is 1800MHz but it can't be scaled at more than
1600MHz :
cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
1800000
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1600000
Sometimes the value above is set to 1800000 but I don't know why it's
not always set to cpuinfo_max_freq.
