weston: Port headless backend to new output handling API This is a complete port of the headless backend that uses the recently added output handling API for output configuration. - Output can be configured at runtime by passing the necessary configuration parameters, which can be filled in manually, obtained from the configuration file or obtained from the command line using previously added functionality. It is required that the scale and transform values are set using the previously added functionality. - Output can be created at runtime using the output API. The output creation only creates a pending output, which needs to be configured the same way as mentioned above. After everything has been set, output needs to be enabled manually using weston_output_enable(). Same as before, a single output is created at runtime using the default configuration or a configuration parsed from the command line. The no-outputs functionality is also preserved, which means that no output will be created initially, but more outputs can be added at runtime using the output API. New feature: This patch also adds, as a bonus of using shared functionality, support for setting options for outputs created by this backend in the weston config file in addition to setting them from the command line. v2: - Fix wet_configure_windowed_output_from_config() usage. - Call headless_output_disable() explicitly from headless_output_destroy(). v3: - Add scale support to output width and height. - Use scaled values in calls to various functions which require width and height. - Disallow calling headless_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). - Bump weston_headless_backend_config version to 2.

libweston: Introduce zwp_linux_explicit_synchronization_v1 Introduce support for the zwp_linux_explicit_synchronization_unstable_v1 protocol with an implementation of the zwp_linux_explicit_synchronization_v1 interface. Explicit synchronization provides a more versatile notification mechanism for buffer readiness and availability, and can be used to improve efficiency by integrating with related functionality in display and graphics APIs. In addition, the per-commit nature of the release events provided by this protocol potentially offers a solution to a deficiency of the wl_buffer.release event (see https://gitlab.freedesktop.org/wayland/wayland/issues/46). Support for this protocol depends on the capabilities of the backend, so we don't register it by default but provide a function which each backend will need to call. In this commit only the headless backend when using the noop renderer supports this to enable testing. Note that the zwp_surface_synchronization_v1 interface, which contains the core functionality of the protocol, is not implemented in this commit. Support for it will be added in future commits. Changes in v7: - Added some information in the commit message about the benefits of the explicit sync protocol. Changes in v6: - Fall back to advertising minor version 1 of the explicit sync protocol, although we support minor version 2 features, until the new wayland-protocols version is released. Changes in v5: - Meson support. - Advertise minor version 2 of the explicit sync protocol. Changes in v4: - Enable explicit sync support in the headless backend for all renderers. Changes in v3: - Use wl_resource_get_version() instead of hardcoding version 1. - Use updated protocol interface names. - Use correct format specifier for resource id. - Change test name to 'linux-explicit-synchronization.weston' (s/_/-/g). Changes in v2: - Move implementation to separate file so protocol can be registered on demand by backends. - Register protocol in headless+noop backend for testing purposes.

compositor: set presentation.presented flags Change weston_output_finish_frame() signature so that backends are required to set the flags, that will be reported on the Presentation 'presented' event. This is meant for output-wide feedback flags. Flags that vary per wl_surface are subject for the following patch. All start_repaint_loop functions use the special private flag PRESENTATION_FEEDBACK_INVALID to mark, that this call of weston_output_finish_frame() cannot trigger the 'presented' event. If it does, we now hit an assert, and should then investigate why a fake update triggered Presentation feedback. DRM: Page flip is always vsync'd, and always gets the completion timestamp from the kernel which should correspond well to hardware. Completion is triggered by the kernel/hardware. Vblank handler is only used with the broken planes path, therefore do not report VSYNC, because we cannot guarantee all the planes updated at the same time. We cannot set the INVALID, because it would abort the compositor if the broken planes path was ever used. This is a hack that will get fixed with nuclear pageflip support in the future. fbdev: No vsync, update done by copy, no completion event from hardware, and completion time is totally fake. headless: No real output to update. RDP: Guessing that maybe no vsync, fake time, and copy make sense (pixels sent over network). Also no event that the pixels have been shown? RPI: Presumably Dispmanx updates are vsync'd. We get a completion event from the driver, but need to read the clock ourselves, so the completion time is somewhat unreliable. Zero-copy flag not implemented though it would be theoretically possible with EGL clients (zero-copy is a per-surface flag anyway, so in this patch). Wayland: No information how the host compositor is doing updates, so make a safe guess without assuming vsync or hardware completion event. While we do get some timestamp from the host compositor, it is not the completion time. Would need to hook to the Presentation extension of the host compositor to get more accurate flags. X11: No idea about vsync, completion event, or copying. Also the timestamp is a fake.

weston: Port headless backend to new output handling API This is a complete port of the headless backend that uses the recently added output handling API for output configuration. - Output can be configured at runtime by passing the necessary configuration parameters, which can be filled in manually, obtained from the configuration file or obtained from the command line using previously added functionality. It is required that the scale and transform values are set using the previously added functionality. - Output can be created at runtime using the output API. The output creation only creates a pending output, which needs to be configured the same way as mentioned above. After everything has been set, output needs to be enabled manually using weston_output_enable(). Same as before, a single output is created at runtime using the default configuration or a configuration parsed from the command line. The no-outputs functionality is also preserved, which means that no output will be created initially, but more outputs can be added at runtime using the output API. New feature: This patch also adds, as a bonus of using shared functionality, support for setting options for outputs created by this backend in the weston config file in addition to setting them from the command line. v2: - Fix wet_configure_windowed_output_from_config() usage. - Call headless_output_disable() explicitly from headless_output_destroy(). v3: - Add scale support to output width and height. - Use scaled values in calls to various functions which require width and height. - Disallow calling headless_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). - Bump weston_headless_backend_config version to 2.

libweston: Introduce zwp_linux_explicit_synchronization_v1 Introduce support for the zwp_linux_explicit_synchronization_unstable_v1 protocol with an implementation of the zwp_linux_explicit_synchronization_v1 interface. Explicit synchronization provides a more versatile notification mechanism for buffer readiness and availability, and can be used to improve efficiency by integrating with related functionality in display and graphics APIs. In addition, the per-commit nature of the release events provided by this protocol potentially offers a solution to a deficiency of the wl_buffer.release event (see https://gitlab.freedesktop.org/wayland/wayland/issues/46). Support for this protocol depends on the capabilities of the backend, so we don't register it by default but provide a function which each backend will need to call. In this commit only the headless backend when using the noop renderer supports this to enable testing. Note that the zwp_surface_synchronization_v1 interface, which contains the core functionality of the protocol, is not implemented in this commit. Support for it will be added in future commits. Changes in v7: - Added some information in the commit message about the benefits of the explicit sync protocol. Changes in v6: - Fall back to advertising minor version 1 of the explicit sync protocol, although we support minor version 2 features, until the new wayland-protocols version is released. Changes in v5: - Meson support. - Advertise minor version 2 of the explicit sync protocol. Changes in v4: - Enable explicit sync support in the headless backend for all renderers. Changes in v3: - Use wl_resource_get_version() instead of hardcoding version 1. - Use updated protocol interface names. - Use correct format specifier for resource id. - Change test name to 'linux-explicit-synchronization.weston' (s/_/-/g). Changes in v2: - Move implementation to separate file so protocol can be registered on demand by backends. - Register protocol in headless+noop backend for testing purposes.

weston: Port headless backend to new output handling API This is a complete port of the headless backend that uses the recently added output handling API for output configuration. - Output can be configured at runtime by passing the necessary configuration parameters, which can be filled in manually, obtained from the configuration file or obtained from the command line using previously added functionality. It is required that the scale and transform values are set using the previously added functionality. - Output can be created at runtime using the output API. The output creation only creates a pending output, which needs to be configured the same way as mentioned above. After everything has been set, output needs to be enabled manually using weston_output_enable(). Same as before, a single output is created at runtime using the default configuration or a configuration parsed from the command line. The no-outputs functionality is also preserved, which means that no output will be created initially, but more outputs can be added at runtime using the output API. New feature: This patch also adds, as a bonus of using shared functionality, support for setting options for outputs created by this backend in the weston config file in addition to setting them from the command line. v2: - Fix wet_configure_windowed_output_from_config() usage. - Call headless_output_disable() explicitly from headless_output_destroy(). v3: - Add scale support to output width and height. - Use scaled values in calls to various functions which require width and height. - Disallow calling headless_output_configure more than once. - Remove unneeded checks for output->name == NULL as that has been disallowed. - Use weston_compositor_add_pending_output(). - Bump weston_headless_backend_config version to 2.
