Lucid Sleep Support Is Being Worked On For The Upstream Linux Kernel
Written by Michael Larabel in Linux Kernel on 1 May 2015 at 10:12 AM EDT. 16 Comments
Chrome OS supports "Lucid Sleep", which is a mode of allowing the system to carry out various tasks while the system is in a low-power mode or even suspended, and similar to Microsoft InstantGo. This feature, which allows for tasks like checking of new emails or instant messages while the system is suspended, is being worked on for (hopeful) eventual upstreaming into the mainline Linux kernel.

Tomeu Vizoso has shared that one of the Chrome OS features he's working to upstream in the mainline Linux kernel is Google's Lucid Sleep. While this could be implemented in user-space alone, Tomeu is working on porting the proper implementation of Lucid Sleep to the upstream Linux kernel.

While the work isn't close to being ready for proposing for mainline, those wishing to find out more about Lucid Sleep plans for Linux can read Vizoso's blog post.
