apport information
** Tags added: apport-collected
** Description changed:
No matter which governor and/or frequency I set via cpufreq-set, the 2 cores
on my macbook 2,5 are always running at the slowest frequency, ie 1.60 ghz,
according to cpufreq-info readings *from hardware*.
According to cpufreq-info readings from cpufreq-core, the frequency varies,
but it doesn't.
In other terms, "/sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq"
always reports "1596000" (1.60 Ghz), no matter what
"/sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq" is reporting.
According to "Documentation/cpu-freq/user-guide.txt":
cpuinfo_cur_freq : Current frequency of the CPU as obtained from
the hardware, in KHz. This is the frequency
the CPU actually runs at.
scaling_cur_freq : Current frequency of the CPU as determined by
the governor and cpufreq core, in KHz. This is
the frequency the kernel thinks the CPU runs
at.
