Daniel Vetter of Intel's Open-Source Technology Center and the lead Intel DRM maintainer presented on the state of atomic mode-setting. For those out of the loop, one of the primary benefits of the DRM driver supporting atomic mode-setting is that it can allow a full mode-set operation to be tested prior to actually being committed to ensure it can be properly handled by the driver and display hardware. For end-users, this is meant to yield less problems and ideally avoid any display flickering. There's also interesting atomic mode-setting endeavors being pursued within the Wayland world and other areas for innovation like asynchronous atomic mode-setting.
If atomic mode-setting is something that gets you going, Daniel has published his PDF slides. He covers more what this feature is about, ongoing work, and future plans for astomic mode-setting.
