				|  - sync-to-vblank
 | |
| 
 | |
|  - switch scanout when top surface is full screen
 | |
| 
 | |
|     - what about cursors then?  maybe use hw cursors if the cursor
 | |
|       satisfies hw limitations (64x64, only one cursor), switch to
 | |
|       composited cursors if not.
 | |
| 
 | |
|  - multihead, screen geometry and crtc layout protocol, hotplug
 | |
| 
 | |
|  - input device discovery, hotplug
 | |
| 
 | |
|     - Advertise axes as part of the discovery, use something like
 | |
|       "org.wayland.input.x" to identify the axes.
 | |
| 
 | |
|  - wayland-system-compositor
 | |
| 
 | |
|     - device kit/libudev/console kit integration to discover seats,
 | |
|       that is, groups of input devices and outputs that provide a
 | |
|       means for one user to interact with the system.  That is,
 | |
|       typically a mouse, keyboard and a screen.  The input devices
 | |
|       will just be evdev devices, the outputs will be a drm device
 | |
|       filename and the specific outputs accessible throught that drm
 | |
|       device.
 | |
| 
 | |
|  - send drm device in connection info, probably just udev path.
 | |
| 
 | |
|  - cairo-drm; wayland needs cairo-drm one way or another:
 | |
| 
 | |
|     - chris wilson (ickle) is doing cairo-drm for i915 now, basically
 | |
|       the pixman-drm idean, but inside cairo instead.
 | |
| 
 | |
|     - pixman-drm; move the ddx driver batchbuffer logic into libdrm
 | |
|       and write native, direct rendering acceleration code in
 | |
|       pixman-drm.  is a clean approach in that we avoid the mess of
 | |
|       the global GL context leaking through to applications, and we
 | |
|       can bootstrap this project by pulling in the EXA hooks from the
 | |
|       DDX drivers.
 | |
| 
 | |
|     - use open gl behind the scenes a la glitz.
 | |
| 
 | |
|     - should be possible to provide a realistic api and then stub out
 | |
|       the implementation with pwrite and pread so gtk+ port can proceed.
 | |
| 
 | |
|  - XKB like client side library for translating keyboard events to
 | |
|    more useful keycodes and modifiers etc.  Will probably be shared
 | |
|    between toolkits as a low-level library.
 | |
| 
 | |
|  - port gtk+
 | |
| 
 | |
|     - eek, so much X legacy stuff there...
 | |
| 
 | |
|     - draw window decorations in gtkwindow.c
 | |
| 
 | |
|     - start from alexl's client-side-windows branch
 | |
| 
 | |
|     - Details about pointer grabs. wayland doesn't have active grabs,
 | |
|       menus will behave subtly different.  Under X, clicking a menu
 | |
|       open grabs the pointer and clicking outside the window pops down
 | |
|       the menu and swallows the click.  without active grabs we can't
 | |
|       swallow the click.  I'm sure there much more...
 | |
| 
 | |
|  - Port Qt?  There's already talk about this on the list.
 | |
| 
 | |
|  - X on Wayland
 | |
| 
 | |
|     - move most of the code from xf86-video-intel into a Xorg wayland
 | |
|       module.
 | |
| 
 | |
|     - don't ask KMS for available output and modes, use the info from
 | |
|       the wayland server.  then stop mooching off of drmmode.c.
 | |
| 
 | |
|     - map multiple wayland input devices to MPX in Xorg.
 | |
| 
 | |
|     - rootless; avoid allocating and setting the front buffer, draw
 | |
|       window decorations in the X server (!), how to map input?
 | |
| 
 | |
|  - gnome-shell as a wayland session compositor
 | |
| 
 | |
|     - runs as a client of the wayland session compositor, uses
 | |
|       clutter+egl on wayland
 | |
| 
 | |
|     - talks to an Xorg server as the compositing and window manager
 | |
|       for that server and renders the output to a wayland surface.
 | |
|       the Xorg server should be modified to take input from the system
 | |
|       compositor through gnome-shell, but not allocate a front buffer.
 | |
| 
 | |
|     - make gnome-shell itself a nested wayland server and allow native
 | |
|       wayland clients to connect and can native wayland windows with
 | |
|       the windows from the X server.
 | |
| 
 | |
|  - qemu as a wayland client; session surface as X case
 | |
| 
 | |
|     - qemu has too simple acceleration, so a Wayland backend like the
 | |
|       SDL/VNC ones it has now is trivial.
 | |
| 
 | |
|     - paravirt: forward wayland screen info as mmio, expose gem ioctls as mmio
 | |
| 
 | |
|     - mapping vmem is tricky, should try to only use ioctl (pwrite+pread)
 | |
| 
 | |
|     - not useful for Windows without a windows paravirt driver.
 | |
| 
 | |
|     - two approaches: 1) do a toplevel qemu window, or 2) expose a
 | |
|       wayland server in the guest that forwards to the host wayland
 | |
|       server, ie a "remote" compositor, but with the gem buffers
 | |
|       shared.  could do a wl_connection directly on mmio memory, with
 | |
|       head and tail pointers.  use an alloc_head register to indicate
 | |
|       desired data to write, if it overwrites tail, block guest.  just
 | |
|       a socket would be easier.
 | |
| 
 | |
|  - make libwayland-client less ghetto
 | |
| 
 | |
|  - sparse based idl compiler
 | |
| 
 | |
|  - actually make batch/commit batch up commands
 | |
| 
 | |
|  - protocol for setting the cursor image
 | |
| 
 | |
|     - should we have a mechanism to attach surface to cursor for
 | |
|       guaranteed non-laggy drag?
 | |
| 
 | |
|  - auth; We need to generate a random socket name and advertise that
 | |
|    on dbus along with a connection cookie.  Something like a method
 | |
|    that returns the socket name and a connection cookie.  The
 | |
|    connection cookie is just another random string that the client
 | |
|    must pass to the wayland server to become authenticated.  The
 | |
|    Wayland server generates the cookie on demand when the dbus method
 | |
|    is called and expires it after 5s or so.
 | |
| 
 | |
|  - enter/leave events from the input devices
 | |
| 
 | |
|  - gain, lose keyboard focus events; this event carries information
 | |
|    about which keys are currently held down as a surface gains focus
 | |
|    so the client can deduce modifier state.
 | |
| 
 | |
|  - Range protocol may not be sufficient... if a server cycles through
 | |
|    2^32 object IDs we don't have a way to handle wrapping.  And since
 | |
|    we hand out a range of 256 IDs to each new clients, we're just
 | |
|    talking about 2^24 clients.  That's 31 years with a new client
 | |
|    every minute...  Maybe just use bigger ranges, then it's feasible
 | |
|    to track and garbage collect them when a client dies. |
