Smithay Files

Large parts of Smithay were changed with numerous API changes. It is thus recommended to approach version 0.3 as if it was a new crate altogether compared to 0.2.

The most notable changes are:

• Deep refactor of the graphics backends around a workflows centered on allocating graphics buffers, and a Gles2-based renderer abstraction is provided.
• Support for DRM atomic modesetting as well as client-provided DMABUF
• Most backends are now calloop event sources generating events. The recommended organization for your smithay-based compositor is thus to centralize most of your logic on a global state struct, and delegate event handling to it via the shared data mechanism of calloop. Most of the callbacks you provide to Smithay are given mutable access to this shared data.
• The wayland::compositor handling logic now automatically handles state tracking and delayed commit for wayland surfaces.

Many thanks to the new contributors to Smithay, who contributed the following:

• Support for libseat as a session backend, by @PolyMeilex
• Support for graphics tablets via the tablet protocol extension, by @PolyMeilex
• Support for running Smithay on aarch64 architectures, by @cmeissl
• A rework of the xdg-shell handlers to better fit the protocol logic and correctly track configure events, by @cmeissl
• Basic Xwayland support, by @psychon
