weston 12.0.0
posted by Roy Schestowitz on May 18, 2023
Hi all,
This is the official release for weston 12.0.0.
Highlights for this release:
- backend-drm: multiple GPU support, by using --additional-devices to specify
secondary DRM devices, in the form of a comma-separated list of devices.
Inteded as separated output devices (KMS), not as render devices
- backend-drm: add support for HDMI content type: graphics, photo, cinema and
game.
- backend-drm: Added support for tearing-control protocol
- backend-drm: Added plane rotation property and make use of when possible
- backend-drm: Added supported formats for writeback connectors, and with it
a writeback screen shooter
- backend-drm: Added plane alpha DRM-property
- backend-drm: use libdisplay-info as a better alternative for parsing EDID
- backed-vnc: a new backend similar to backend-rpd, based on aml and neatvnc,
with TLS support and user authentication. Both aml and neatvnc are set-up
as subprojects
- backend-pipewire: added PipeWire backend
- backend-wayland: allow resizing with xdg-shell
- backend-rdp: preliminary rdp multi-head support
(and many other bug-fixes in-between)
- backend-headless: added output decorations for testing out the color-lcms
plugin.
- launcher-logind has been deprecated and disabled by default. As
launcher-libseat supports logind, this shouldn't cause any regressions
- libweston/desktop (formally libweston-desktop) would take into account client
pending state, when there's no buffer attached. Useful in situations where the
clients would like to start from the beginning in a maximized/fullscreen
state
- protocol: new screenshooter protocol: weston-output-capture. This new
protocol is as a Weston public extension. The older weston-screenshooter
protocol has been removed.
- xwayland: multiple fixes related to seat handling, selection and window
state modifications
- xwayland: Add support for xwayland_shell_v1 protocol
- libweston: Add user authentication support via PAM
- libweston: update wl_output to version 4, to also include name and description
events.
- compositor: added a short-form for loading backends -- this allows the
use of "--backend=headless" instead of "--backend=headless-backend.so".
Short-form for shells was also added: pass "--shell=foo", rather than
"--shell=foo-shell.so". Renderers can be specified the same,
by using "--renderer=gl|pixman"
Backwards compatible with the older form still supported.
- clients/simple-egl: Dropped Y_INVERT linux-dmabuf flag. In order to keep the
same orientation we had with that flag the client is now rendered up-side
down (explicitly)
- clients/simple-egl: Implement fractional-scale protocol support
- clients/simple-egl: adds a vertical bar drawing mode, if started with -v, for testing
out tearing
- simple-dmabuf-v4l: Add support to NV12 devices that combine planes
- ivi-shell: activate keyboard focus for xdg-shell surface, similar to how we
handle keyboard input activation in desktop-shell and kiosk-shell. A few more
updates have landed, as well as bug-fixes. Includes additional signal
event handling (output creation and destruction) but also specific signals
for controller destruction. Added input panel support
- many more bug-fixes across the board: desktop-shell, kiosk-shell, DRM virtual
API (remoting/pipewire plugins) and screen-share module
Internal changes:
- backend-drm: avoid doing a modeset if max_bpc connector property is set,
while the output is set to current
- Pixman/GL renderer and x11, rdp, wayland backends: the Pixman and GL renderer
now supports resizing its shadow buffer, and with it the rdp, x11 and wayland
backends now make use of it
- color-lcms: improvements in color transformation precision and performance
API changes:
- weston_log_paced() has been added which can help out to throttle messages
- added weston_shell_utils namespace: common shell-utils API which can be
reused by other shell clients. desktop-shell/kiosk-shell has been using
these for some time, but it wasn't part of libweston until now
- make weston_head_set_device_changed() public
- introduction of weston_coord_surface_to_global(), weston_coord_global_to_surface(),
weston_coord_surface_to_buffer(), weston_coord_global_from_output_point() and
weston_matrix_transform_coord(). These are a family of coordinate vector
structures for coordinate pairs. These have been extensively used in
all compositor code and in libweston, together with the introduction
of weston_coord
- added weston_surface_is_unmapping() for cases where the client is attaching
an empty buffer (after having a previously valid one). This would also cause
libweston/desktop to emit a weston_desktop_api_committed() call that can
be handled by a shell client implementing weston_desktop_api
- added weston_output_power_on() and its counter-part weston_output_power_off()
in order to handle multiple weston_output independently using their
power state (DPMS on/off)
Breaking changes for users:
- libweston-desktop DSO has been incorporated into libweston. Linking now with
libweston would provide access to the former libweston-desktop library. Users
of libweston-desktop would need to adjust their headers to
rather than using .
Otherwise, the API itself remains the same
- ivi-layout: simplify API - all struct ivi_layout_interface function pointers
have their return values removed
