Hi there,
Power management WG is invistigating on a tool named PowerTOP, which can spit out real time data on various aspects of a running system, in terms of power related information. However, occasionally some PowerTOP features need kernel patch. We'd like users to be able to use these latest features without having to wait up to 3 months for Linus to make a release with the kernel portion -- as the original patch developer(s) said. There are totally 3 patches which I had already enclosed them in the attachment. Except vfs.patch, the rest two are original and can be applied on linaro kernel without any changes. vfs.patch is changed a little from original one to adapt current linaro kernel. Hope John would give it a thought to merge these patch in Linaro kernel.
Yong
