My gsoc2012 project is adding cpuidle support to haiku. As we all know, transistor power consumption is composed of dynamic and static ones. The former is due to charge/discharge of capacitance and other switching activity; the later is due to leakage and bias current. In the following section, I’d like to simply abstract power saving technology in nowadays cpu; powering saving technology in nowadays OS; what’s missing in haiku, IOW the reason why I want to work on it.
This is a companion discussion topic for the original entry at https://www.haiku-os.org/blog/yongcong/2012-04-27_gsoc2012_cpuidle_project_introduction/
