Re: [Gumstix-users] Set CPU rate

[xiaoyan.lu <xia...@uc...>]

Thank you! I can lower MPU rate now!

Beside saving power by lowering MPU rate, I wish to physically make useless
components sleep (like graphic card, voice card etc.)  via Power Management.
Thus, power consumption could be further reduced. I want to do this because
in my application, I hope Gumstix with independent power source can work for
a long period.

1. Poky Linux or Angstorm Linux contains such a Power Management Module?
2. Does a Linux Kernel Version contain such Power Management Module?
3. I found there is a TI OMAP patch might be useful. Is there any patch like
OMAP that can apply to Poky Linux?(Which is the default image I compiled by
Yocto.)
