Xwayland’s Explicit GPU Synchronization: A Game-Changer for NVIDIA Users

After a long wait, Xwayland has finally integrated the code for Explicit GPU Synchronization, marking a significant milestone for NVIDIA GPU users. The merge request, spearheaded by Erik Kurzinger from NVIDIA, outlines the proposal to incorporate explicit GPU synchronization into the DRI3 and Present extensions, with a specific focus on Xwayland.

“Here is our proposal for adding explicit GPU synchronization to the DRI3 and Present extensions, along with an implementation for Xwayland,” stated Kurzinger.

The move towards explicit synchronization is seen as a crucial step forward for the Linux graphics stack, especially given NVIDIA’s driver’s lack of implicit sync support. The community appears to be rallying behind this approach, recognizing its potential to enhance performance and compatibility across the board.

Drawing inspiration from the Wayland wp_linux_explicit_sync_v2 protocol, the design leverages DRM syncobjs as the primary primitive. This choice offers various advantages, including streamlining development for client-side drivers and paving the way for Xwayland to seamlessly integrate support for the Wayland explicit sync protocol as it gains wider adoption among compositors.

With the impending release of an NVIDIA beta driver expected to include support for explicit GPU synchronization next month, the momentum is building. GNOME has already incorporated the necessary code, while KDE is in the process of merging the feature. Additionally, Mesa has successfully integrated the update, underscoring the industry-wide embrace of this advancement.

This development signifies a positive shift in the Linux graphics landscape, promising improved performance and compatibility for NVIDIA GPU users. The community eagerly anticipates the forthcoming enhancements and looks forward to reaping the benefits of explicit GPU synchronization.
