Olivier Certner

Olivier has been continuously using FreeBSD on all his machines and those of some of the companies he worked with since the end of 2004. During this time, he has grown a set of private customizations including modifications to rc scripts and some kernel bits. After having worked for over 15 years in the CAD and finance sectors, he lately switched back to pure IT topics, and in particular operating system development. His main interests are centered around kernel development, with particular focuses on power management, security, scheduling, file systems and jails.

Supporting hibernate (S4) on FreeBSD
Olivier Certner

In this talk, we describe our current work in progress on supporting hibernate on FreeBSD. First, we outline the different high-level steps that are necessary. Then, we delve into how we actually implement them, including ACPI interfacing and programming, how we take a snapshot of kernel memory, save the image to disk and restore it on boot. Finally, we report on this development's status.
