Haruna 0.11.0

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
