Breaking changes

DrmSyncobjHandler::drm_syncobj_state is now Optional. Whenever state is None ImportTimeline request will result in InvalidTimeline protocol error. This allows one to destroy DrmSyncobjState by calling DrmSyncobjState::into_global()

:::diff
-fn DrmSyncobjHandler::drm_syncobj_state(&mut self) -> &mut DrmSyncobjState
+fn DrmSyncobjHandler::drm_syncobj_state(&mut self) -> Option<&mut DrmSyncobjState>

DrmTimeline constructor now accepts OwnedFd:

:::diff
-fn DrmTimeline::new(device: &DrmDeviceFd, fd: BorrowedFd<'_>) -> io::Result<Self>
+fn DrmTimeline::new(device: &DrmDeviceFd, fd: OwnedFd) -> io::Result<Self>

DrmSyncPoint::eventfd now returns Arc<OwnedFd>:

:::diff
-fn DrmSyncPoint::eventfd(&self) -> io::Result<OwnedFd>
+fn DrmSyncPoint::eventfd(&self) -> io::Result<Arc<OwnedFd>>

GbmFramebufferExporter constructor now accepts import_node, it will be used to filter DMA-BUFs to only those originating from a specific device before considering them for direct scanout. If import_node is None direct-scanout of client-buffers won't be used.

:::diff
-fn GbmFramebufferExporter::new(gbm: Device<A>) -> Self
+fn GbmFramebufferExporter::new(gbm: Device<A>, import_node: Option<DrmNode>) -> Self

Additions

WeakDrmDeviceFd

:::rs
/// Returns a weak reference to the underlying device
fn DrmDeviceFd::downgrade(&self) -> WeakDrmDeviceFd;
/// Construct an empty Weak reference, that will never upgrade successfully
fn WeakDrmDeviceFd::new() -> Self;
/// Try to upgrade to a strong reference
fn WeakDrmDeviceFd::upgrade(&self) -> Option<DrmDeviceFd>;

KeyboardHandle::set_modifier_state

:::rs
/// Set the modifiers state.
fn KeyboardHandle::set_modifier_state(&self, mods_state: ModifiersState) -> u32;
/// Serialize modifier state back to be sent to xkb.
fn ModifiersState::serialize_back(&self, state: &xkb::State) -> SerializedMods;

XWaylandKeyboardGrab

:::rs
/// Get the `zwp_xwayland_keyboard_grab_v1` object that created the grab
fn XWaylandKeyboardGrab::grab(&self) -> &ZwpXwaylandKeyboardGrabV1;
/// Grab is now clonable
impl Clone for XWaylandKeyboardGrab;

X11Surface

:::rs
/// Returns the hints for the underlying X11 window
fn X11Surface::hints(&self) -> Option<x11rb::properties::WmHints>;
/// Get the client PID associated with the X11 window.
fn X11Surface::get_client_pid(&self) -> Result<u32, Box<dyn Error>>;

DrmSyncobjState

:::rs
/// Destroys the state and returns the `GlobalId` for compositors to disable/destroy.
fn DrmSyncobjState::into_global(self) -> GlobalId;
/// Sets a new `import_device` to import the syncobj fds and wait on them.
fn DrmSyncobjState::update_device(&mut self, import_device: DrmDeviceFd);
