could someone with one of Lehto's kernels please report
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
make a phone call, and report the same value after the call?
thanks!

Before a call:

Code:

Nokia-N900-51-1:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 
900000

After a call:

Code:

Nokia-N900-51-1:~# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 
600000

Additional info:

Code:

Nokia-N900-51-1:~# cat /sys/devices/system/cpu/cpu0/cpufreq//cpuinfo_max_freq 
930000
Nokia-N900-51-1:~# cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state 
930000 127730
595000 1264
500000 20578
250000 317428
125000 11314

And a couple of seconds later:

Code:

Nokia-N900-51-1:~# cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state 
930000 128530
595000 1264
500000 20578
250000 317728
125000 12292

It reports a max of 600mhz - but still uses the 930mhz.
