libweston: introduce CMS component architecture See: https://gitlab.freedesktop.org/wayland/weston/-/issues/467#note_814985 This starts building the framework required for implementing color management. The main new interface is struct weston_color_manager. This commit also adds a no-op color manager implementation, which is used if no other color manager is loaded. This no-op color manager simply provides identity color transforms for everything, so that Weston keeps running exactly like before. weston_color_manager interface is incomplete and will be extended later. Colorspace objects are not introduced in this commit. However, when client content colorspace and output colorspace definitions are combined, they will produce color transformations from client content to output blending space and from output blending space to output space. This commit introduces a placeholder struct for color transforms, weston_color_transform. Objects of this type are expected to be heavy to create and store, which is why they are designed to be shared as much as possible, ideally making their instances unique. As color transform description is intended to be generic in libweston core, renderers and backends are expected to derive their own state for each transform object as necessary. Creating and storing the derived state maybe be expensive as well, more the reason to re-use these objects as much as possible. E.g. GL-renderer might upload a 3D LUT into a texture and keep the texture around. DRM-backend might create a KMS blob for a LUT and keep that around. As a color transform depends on both the surface and the output, a transform object may need to be created for each unique pair of them. Therefore color transforms are referenced from weston_paint_node. As paint nodes exist for not just surface+output but surface+view+output triplets, the code ensures that all paint nodes (having different view) for the same surface+output have the same color transform state. As a special case, if weston_color_transform is NULL, it means identity transform. This short-circuits some checks and memory allocations, but it does mean we use a separate member on weston_paint_node to know if the color transform has been initialized or not. Color transformations are pre-created at the weston_output paint_node_z_order_list creation step. Currently the z order lists contain all views globally, which means we populate color transforms we may never need, e.g. a view is never shown on a particular output. This problem should get fixed naturally when z order lists are constructed "pruned" in the future: to contain only those paint nodes that actually contribute to the output's image. As nothing actually supports color transforms yet, both renderers and the DRM-backend assert that they only get identity transforms. This check has the side-effect that all surface-output pairs actually get a weston_surface_color_transform_ref even though it points to NULL weston_color_transform. This design is inspired by Sebastian Wick's Weston color management work. Co-authored-by: Sebastian Wick <sebastian@sebastianwick.net> Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>

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.
