Subject: How to enable dvfs in omap.
Hi all,
I am using omap 2.6.37 running overo board. I have enabled the
following
option in the kernel menunconfig,
CPU Power Management --->
â â [*] CPU Frequency scaling
â â [ ] Enable CPUfreq debugging
â â<*> CPU frequency translation statistics
â â [*] CPU frequency translation statistics details
â â Default CPUFreq governor (ondemand) --->
â â -*- 'performance' governor
â â<M> 'powersave' governor
â â<*> 'userspace' governor for userspace frequency scaling
â â -*- 'ondemand' cpufreq policy governor
â â<*> 'conservative' cpufreq governor
â â [ ] CPU idle PM support
but still I could find the sys and entry in
/sys/devices/system/cpu/cpufreq/ directory. Could some one help me
to enable DVFS.
That's because tts not supported yet.
You may want to look at this[1] series which is in progress
to enable the support.

Santosh
