Includes winit Wayland input audit for servo-shell integration planning.
New files:
- crates/weft-servo-shell/: new workspace member
- Cargo.toml: anyhow + tracing deps; no servo dep yet (requires git
dependency on github.com/servo/servo with multi-minute build; deferred
until embedder contract is confirmed)
- src/main.rs: reads WAYLAND_DISPLAY and WEFT_SYSTEM_UI_HTML, locates
system-ui.html from packaged path, calls embed_servo() stub that
returns a descriptive error explaining the integration work remaining
- infra/shell/system-ui.html: system UI document per blueprint Section 5
DOM structure (weft-desktop, weft-wallpaper, weft-taskbar, weft-launcher,
weft-notification-center, weft-window); includes clock and launcher toggle
- infra/systemd/servo-shell.service: Requires+After weft-compositor.service,
Type=simple, Restart=on-failure
- docs/architecture/winit-wayland-audit.md: audit of winit 0.30.x Wayland
backend against WEFT input requirements; identifies keyboard shortcut
inhibit gap, touch gesture gap, IME incomplete (zwp_text_input_v3),
frame pacing absent (wp_presentation_time), DMA-BUF unverified;
none block initial integration; all tracked as pre-GA work items
Modified:
- Cargo.toml: add weft-servo-shell to workspace members
- scripts/wsl-check.sh: switch to --workspace for all three gates
Replace the clear-colour-only stub in render_output with full
surface compositing via Space::render_elements_for_output.
Changes:
- drm_device.rs: add start_time: Instant to WeftDrmData for elapsed-
time frame callbacks
- drm.rs: rewrite render_output rendering block
- collect SpaceRenderElements from Space via render_elements_for_output
which includes both mapped windows and wlr-layer-shell surfaces from
layer_map_for_output (sorted by z-index, clipped to output geometry)
- pass collected elements to DrmOutput::render_frame
- fix send_frame timing from Duration::ZERO to start_time.elapsed()
with 16ms throttle hint
- add space.refresh() and popups.cleanup() after each frame
Use explicit inner block to scope space+drm borrows so post-render
bookkeeping can access state mutably
Cursor rendering deferred requires cursor theme loading or MemoryRenderBuffer
setup; tracked separately.
Fixes found by running cargo check + clippy -D warnings + fmt --check
on openSUSE Tumbleweed WSL2 (Rust 1.93.0).
input.rs:
- Add GestureBeginEvent (fingers()), GestureEndEvent (cancelled()),
TouchEvent (slot()) supertrait imports
- Add explicit ::<B> turbofish to all handle_* dispatch calls Rust
cannot reverse-infer B from an associated type bound
- Remove now-redundant specific gesture/touch event trait imports
state.rs:
- Add reposition_request to XdgShellHandler (E0046)
- Wrap protocol-level LayerSurface in desktop::LayerSurface::new for
map_layer (E0308)
- Wrap std::env::set_var in unsafe block (E0133, stabilised unsafe in 1.80)
- Add #[allow(dead_code)] on WeftCompositorState protocol state fields
are held for delegate dispatch, not yet consumed
- Remove spurious mut on display binding
drm.rs:
- Revert initialize_output arg to &output (&Output: Into<OutputModeSource>)
- Specify element type via ::<_, WaylandSurfaceRenderElement<_>> turbofish
on initialize_output (E0277/E0308)
- Handle Result from scan_connectors, collect via IntoIterator (E0308)
- Wrap set_var in unsafe block; remove spurious mut on display
- Collapse nested if/if-let blocks per clippy::collapsible_if
- Remove useless .into() on render_node (clippy::useless_conversion)
drm_device.rs:
- Add #[allow(dead_code)] on WeftOutputSurface (device_id, global used
in hotplug handling)
scripts/wsl-check.sh (new):
- WSL2 helper: injects libdisplay-info 0.2.9 shim .pc to satisfy the
< 0.3.0 constraint while openSUSE ships 0.3.0; runs check/clippy/fmt
Add full DRM/KMS backend with libseat session, GBM allocation, EGL
display initialisation, and a GpuManager-driven rendering loop.
- drm_device.rs: type aliases and per-device/per-output state structs
(WeftDrmDevice, WeftOutputSurface, WeftDrmData)
- drm.rs: replace skeleton with complete backend libseat session,
udev device enumeration, libinput event source, connector scanning
via smithay-drm-extras DrmScanner, DrmOutputManager initialisation
per CRTC, VBlank-driven render_output, sd_notify(READY=1)
- state.rs: add drm: Option<WeftDrmData> field; route dmabuf import
through GPU manager when the DRM path is active
- Cargo.toml: add renderer_multi, use_system_lib Smithay features;
add smithay-drm-extras and sd-notify Linux dependencies
render_output submits a clear-colour-only frame to establish
the VBlank pipeline. Surface compositing is wired up in a subsequent commit.
