nsWaylandDisplay
|
|
|
|
Is our connection to Wayland display server,
|
|
holds our display connection (wl_display) and event queue (wl_event_queue).
|
|
|
|
nsWaylandDisplay is created for every thread which sends data to Wayland
|
|
compositor. Wayland events for main thread is served by default Gtk+ loop,
|
|
for other threads (compositor) we must create wl_event_queue and run event loop.
|
|
|
|
|
|
WindowSurfaceWayland
|
|
|
|
Is a Wayland implementation of WindowSurface class for WindowSurfaceProvider,
|
|
we implement Lock() and Commit() interfaces from WindowSurface
|
|
for actual drawing.
|
|
|
|
One WindowSurfaceWayland draws one nsWindow so those are tied 1:1.
|
|
At Wayland level it holds one wl_surface object.
|
|
|
|
To perform visualiation of nsWindow, WindowSurfaceWayland contains one
|
|
wl_surface and two wl_buffer objects (owned by WindowBackBuffer)
|
|
as we use double buffering. When nsWindow drawing is finished to wl_buffer,
|
|
the wl_buffer is attached to wl_surface and it's sent to Wayland compositor.
|
|
|
|
When there's no wl_buffer available for drawing (all wl_buffers are locked in
|
|
compositor for instance) we store the drawing to WindowImageSurface object
|
|
and draw later when wl_buffer becomes availabe or discard the
|
|
WindowImageSurface cache when whole screen is invalidated.
|
|
|
|
WindowBackBuffer
|
|
|
|
Is an abstraction class which provides a wl_buffer for drawing.
|
|
Wl_buffer is a main Wayland object with actual graphics data.
|
|
Wl_buffer basically represent one complete window screen.
|
|
When double buffering is involved every window (GdkWindow for instance)
|
|
utilises two wl_buffers which are cycled. One is filed with data by application
|
|
and one is rendered by compositor.
|
|
|
|
|
|
WindowBackBufferShm
|
|
|
|
It's WindowBackBuffer implementation by shared memory (shm).
|
|
It owns wl_buffer object, owns WaylandShmPool
|
|
(which provides the shared memory) and ties them together.
|
|
|
|
WaylandShmPool
|
|
|
|
WaylandShmPool acts as a manager of shared memory for WindowBackBuffer.
|
|
Allocates it, holds reference to it and releases it.
|
|
|
|
We allocate shared memory (shm) by mmap(..., MAP_SHARED,...) as an interface
|
|
between us and wayland compositor. We draw our graphics data to the shm and
|
|
handle to wayland compositor by WindowBackBuffer/WindowSurfaceWayland
|
|
(wl_buffer/wl_surface).
|
|
|
|
WindowBackBufferDMABuf
|
|
|
|
It's WindowBackBuffer implementation based on DMA Buffer.
|
|
It owns wl_buffer object, owns WaylandDMABufSurface
|
|
(which provides the DMA Buffer) and ties them together.
|
|
|
|
WindowBackBufferDMABuf backend is used only when WaylandDMABufSurface is
|
|
available and widget.wayland_dmabuf_backend.enabled preference is set.
