Today I’m going to start a series of posts giving  an overview about the power savings features present, or under development, in i915 (Intel Graphics Linux Kernel Driver).

Features covered for now in this series will be:

Besides the overview I’m going to detail current implementation status at our driver, how to enable/disable, how to check running status and list known issues.

It is important to say beforehand that some of these power savings features can impact rendering performance, mainly 3D, and sometimes cause some known GPU hangs. So, if you aren’t a hardcore user and is desperate to make your laptop’s battery last a bit longer you might give a chance and try them out.

Also if you find any new bug we encourage you report the bug at https://bugs.freedesktop.org following  our How to report bugs tutorial.
