Linux GPU Drivers Prepare For Global Thermo-Nuclear War
Written by Michael Larabel in X.Org on 5 June 2014 at 12:06 PM EDT. 26 Comments
Atomic mode-setting and nuclear page-flipping is becoming a reality within the open-source Linux graphics stack.

Atomic mode-setting and nuclear page-flipping have been talked about for years on Phoronix in numerous articles while the code is still being refined and readied for mainline inclusion.

For those wondering about what these terms mean -- and Rob Clark's Git branches with this work carrying "global-thermonuclear-war" titles -- Pekka Paalanen has written a lengthy and informative blog post for those wanting to do some educational reading.

Pekka's well-written article covers from the early days of Linux graphics drivers through the advent of KMS/DRM and Wayland and then the current work with universal plane support and the global thermo-nuclear patches. Pekka also covers the challenges presented by G-Sync and FreeSync technologies for the Linux graphics stack. The adaptive-sync standard will cause problems for the Linux graphics stack in its current form but is an issue that can be overcome.
