2022-06-02backend/drm: short-circuit no-op commitsSimon Ser
Some output commits (changing e.g. the output scale or transform) don't require any change in the KMS state. Instead of going through a KMS commit, return early. Blocking KMS commits can be expensive.
2022-06-01backend/drm: make commits without a buffer blockingSimon Ser
The wlr_output API requires compositors to wait for wlr_output.frame before submitting a new buffer. However, compositors can perform a commit which doesn't involve a buffer anytime. If the commit is a modeset, we set DRM_MODE_ATOMIC_ALLOW_MODESET and block until the commit is done. If it isn't, we currently always perform a non-blocking commit. This is an issue because a previous page-flip might still be in flight kernel-side, returning EBUSY. Fix this by using blocking commits when a buffer isn't submitted by the compositor.

2022-06-01xdg-shell: add support for v4Simon Ser
This adds a configure_bounds event to let the client know of the preferred maximum window geometry size.
2022-06-01compositor: send WL_SURFACE_ERROR_INVALID_SIZE for non-cursor surfacesSimon Ser
See the discussion at [1]: there's no easy way to fix libwayland-cursor without a new API. Sending the error for other roles will prevent the same client bug from appearing elsewhere. [1]: https://gitlab.freedesktop.org/wayland/wayland/-/issues/194
2022-06-01scene/output-layout: add initial outputsKirill Primak
2022-06-01scene/output-layout: improve ownership logicKirill Primak
This commit ensures that outputs that weren't created by the output layout helper aren't destroyed on the output layout change. Consider the following piece of logic: // struct wlr_output *o1, *o2; // struct wlr_scene *scene; // struct wlr_output_layout *layout; wlr_scene_attach_output_layout(scene, layout); wlr_output_layout_add_auto(layout, o1); struct wlr_scene_output *so2 = wlr_scene_output_create(scene, o2); wlr_output_layout_move(layout, o1, 100, 200); // so2 is invalid now
2022-06-01scene: add wlr_scene_output.events.destroyKirill Primak
2022-05-31scene/wlr_scene.h: fix indentationKirill Primak
2022-05-31output: drop wlr_output_cursor.events.destroySimon Ser
Compositors can just listen to wlr_output.events.destroy instead.
2022-05-31output: re-implement set_image with set_bufferSimon Ser
Avoids having two code-paths doing the same thing.
2022-05-31output: introduce wlr_output_cursor_set_bufferSimon Ser
This will supersede wlr_output_cursor_set_image, and then later also supersede wlr_output_cursor_set_surface.
2022-05-31output: remove noop backend check in wlr_output_cursor_set_imageSimon Ser
The noop backend doesn't exist anymore.

This seems like nothing interesting was done with this. Let's simplify and allow us some flexibility in the future.

2022-05-31backend/drm: improve atomic commit flag loggingSimon Ser
We weren't logging all of the flags, which made debugging more difficult.
2022-05-30relative-pointer-v1: don't allocate when inertSimon Ser
When the wl_pointer the zwp_relative_pointer_v1 is created with is inert, don't allocate any struct, just leave the resource's data pointer NULL.
2022-05-30relative-pointer-v1: remove unnecessary log messagesSimon Ser
Logging when a client creates or destroys an object is a bit too chatty.
2022-05-30relative-pointer-v1: remove unnecessary commentsSimon Ser
We don't do this in other implementations, so it feels out of place.
2022-05-30wlr_scene: Fix scaling with default source_boxConsolatis
Default to texture instead of destination_box geometry.
2022-05-30relative_pointer: handle inert pointer objectsRouven Czerwinski
Since 5e0ef70cc085 ("seat: Create inert objects for missing capabilities") wlroots can create inert seat objects when the capability is currently missing for the client but it had the capablity before. The client hoever will happily handover the wl_pointer resource to the relative_pointer implementation, creating a NULL pointer dereference when trying to access the seat_client which is set to NULL for inert objects. Since the protocol does not contain an error for such requests, we hand out an relative_pointer handle with the seat set to NULL. We also need to check whether there is an associated seat in send_relative_motion and need to tweak the destroy notifier in case no seat is available. This way we can hand out a valid relative_pointer resource and don't crash the compositor when trying to access an inert seat pointer resource in relative_pointer.

2022-05-30build: make GBM optionalSimon Ser
Now that the DRM backend no longer depends on GBM, we can make it optional. The GLES2 renderer still depends on it because of our EGL device selection. This is useful for compositors with their own renderers, and for compositors using the Vulkan renderer.
2022-05-30output: add wlr_output_commit_stateSimon Ser
Same as wlr_output_commit, but takes a wlr_output_state.

2022-05-30output: add wlr_output_test_stateSimon Ser
Same as wlr_output_test, but takes a wlr_output_state argument.
2022-05-30output: pass wlr_output_state to rendering functionsSimon Ser
No functional change.
2022-05-30output: pass wlr_output_state to output_pending_resolutionSimon Ser
2022-05-30output: pass wlr_output_state to backendSimon Ser
Groundwork for the following commits. The goal is to allow users to specify their own wlr_output_state instead of wlr_output.pending.
2022-05-28gitignore: remove unnecessary entries, add subprojects/Simon Ser
The previous entries aren't used because the build files are self-contained in the Meson build directory. Add subprojects/ because it's common for developers to override Meson dependencies via subproject symlinks.

The values are lowercase, not uppercase.

2022-05-26linux-dmabuf-v1: fix MOD_INVALID handling in feedback tranchesSimon Ser
[1] has changed wlr_drm_format to remove the assumption that MOD_INVALID is always implicitly enabled. MOD_INVALID is now part of the modifier list just like any other modifier. The patch adding support for linux-dmabuf-v1 feedback has been written a lot of time before [1], and hasn't been updated accordingly when merged. This results in MOD_INVALID being advertised twice [2] and other index bugs. Fix these issues by removing special-casing for MOD_INVALID.

2022-05-26output: turn make/model/serial into char *Simon Ser
This allows the make/model/serial to be NULL when unset, and allows them to be longer than the hardcoded array length. This is a breaking change: compositors need to handle the new NULL case, and we stop setting make/model to useless "headless" or "wayland" strings.
2022-05-26backend/drm: fix crash in init_drm_surfaceSimon Ser

2022-05-25render/egl: document wlr_egl_create_with_contextSimon Ser
2022-05-25render/egl: make wlr_egl_{make,unset,is}_current privateSimon Ser
These are trivial wrappers around eglMakeCurrent and eglGetCurrentContext. Compositors which need to call these functions will also call other EGL or GL functions anyways. Let's reduce our API surface a bit by making them private.
2022-05-25render/egl: make wlr_egl struct opaqueSimon Ser
Compositors can use wlr_egl_create_with_context if they need a custom EGL display or context.
2022-05-25render/egl: add wlr_egl_get_{context,display}Simon Ser
This allows compositors to integrate with the wlroots GLES2 renderer, if they need to perform custom GL rendering.
2022-05-25render/egl: drop MESA_EGL_NO_X11_HEADERSSimon Ser
This has been superseded by the standard EGL_NO_X11 switch, supported by Mesa 19.3.0+.
2022-05-25Reformat doc commentsSimon Ser
Unify the way we document our APIs. See CONTRIBUTING.md for the rules.
2022-05-25contributing: add section about documentation conventionsSimon Ser
Document the existing conventions. Use `mystruct.foo` instead of `mystruct::foo` because `::` is pretty alien to C. Instead of backticks, use a different format to reference declarations in our docs: See foo(). See struct foo. See union bar. See enum baz. See typedef meh. This is inspired by the kernel's documentation style [1]. This format has the upside of being pretty natural to write and read, and can be automatically processed by documentation generators.
