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.

libweston: Support zwp_surface_synchronization_v1.set_acquire_fence Implement the set_acquire_fence request of the zwp_surface_synchronization_v1 interface. The implementation uses the acquire fence in two ways: 1. If the associated buffer is used as GL render source, an EGLSyncKHR is created from the fence and used to synchronize access. 2. If the associated buffer is used as a plane framebuffer, the acquire fence is treated as an in-fence for the atomic commit operation. If in-fences are not supported and the buffer has an acquire fence, we don't consider it for plane placement. If the used compositor/renderer doesn't support explicit synchronization, we don't advertise the protocol at all. Currently only the DRM and X11 backends when using the GL renderer advertise the protocol for production use. Issues for discussion --------------------- a. Currently, a server-side wait of EGLSyncKHR is performed before using the EGLImage/texture during rendering. Unfortunately, it's not clear from the specs whether this is generally safe to do, or we need to sync before glEGLImageTargetTexture2DOES. The exception is TEXTURE_EXTERNAL_OES where the spec mentions it's enough to sync and then glBindTexture for any changes to take effect. Changes in v5: - Meson support. - Make explicit sync server error reporting more generic, supporting all explicit sync related interfaces not just wp_linux_surface_synchronization. - Fix typo in warning for missing EGL_KHR_wait_sync extension. - Support minor version 2 of the explicit sync protocol (i.e., support fences for opaque EGL buffers). Changes in v4: - Introduce and use fd_clear and and fd_move helpers. - Don't check for a valid buffer when updating surface acquire fence fd from state. - Assert that pending state acquire fence fd is always clear after a commit. - Clarify that WESTON_CAP_EXPLICIT_SYNC applies to just the renderer. - Check for EGL_KHR_wait_sync before using eglWaitSyncKHR. - Dup the acquire fence before passing to EGL. Changes in v3: - Keep acquire_fence_fd in surface instead of buffer. - Clarify that WESTON_CAP_EXPLICIT_SYNC applies to both backend and renderer. - Move comment about non-ownership of in_fence_fd to struct drm_plane_state definition. - Assert that we don't try to use planes with in-fences when using the legacy KMS API. - Remove unnecessary info from wayland error messages. - Handle acquire fence for subsurface commits. - Guard against self-update in fd_update. - Disconnect the client if acquire fence EGLSyncKHR creation or wait fails. - Use updated protocol interface names. - User correct format specifier for resource ids. - Advertise protocol for X11 backend with GL renderer. Changes in v2: - Remove sync file wait fallbacks. - Raise UNSUPPORTED_BUFFER error at commit if we have an acquire fence, but the committed buffer is not a valid linux_dmabuf. - Don't put buffers with in-fences on planes that don't support in-fences. - Don't advertise explicit sync protocol if backend does not support explicit sync.

Changes in v7: - Remove "partial" from commit title and description. - Fix inverted check when clearing used_in_output_repaint flag. Changes in v5: - Use the new, generic explicit sync server error reporting function. - Introduce and use weston_buffer_release_move. - Introduce internally and use weston_buffer_release_destroy. Changes in v4: - Support the zwp_buffer_release_v1.fenced_release event. - Support release fences in the GL renderer. - Assert that pending state buffer_release is always NULL after a commit. - Simplify weston_buffer_release_reference. - Move removal of destroy listener before resource destruction to avoid concerns about use-after-free in weston_buffer_release_reference - Rename weston_buffer_release_reference.busy_count to ref_count. - Add documentation for weston_buffer_release and ..._reference. Changes in v3: - Raise NO_BUFFER for get_release if no buffer has been committed, don't raise UNSUPPORTED_BUFFER for non-dmabuf buffers, so get_release works for all valid buffers. - Destroy the buffer_release object after sending an event. - Track lifetime of buffer_release objects per commit, independently of any buffers. - Use updated protocol interface names. - Use correct format specifier for resource ids. Changes in v2: - Raise UNSUPPORTED_BUFFER at commit if client has requested a buffer_release, but the committed buffer is not a valid linux_dmabuf. - Remove tests that are not viable anymore due to our inability to create dmabuf buffers and fences in a unit-test environment.

libweston: Support zwp_surface_synchronization_v1.get_release Implement the get_release request of the zwp_surface_synchronization_v1 interface. This commit implements the zwp_buffer_release_v1 interface. It supports the zwp_buffer_release_v1.fenced_release event for surfaces rendered by the GL renderer, and the zwp_buffer_release_v1.immediate_release event for other cases. Note that the immediate_release event is safe to be used for surface buffers used as planes in the DRM backend, since the backend releases them only after the next page flip that doesn't use the buffers has finished.
