2023-10-03treewide: Migrate from sizeof(struct) to sizeof(*pointer) where practicalAlexander Orzechowski
2023-07-11Use wl_container_of() instead of castsSimon Ser
This slightly improves type safety. The culprits were found with: git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'
2023-06-27backend/headless: leave new outputs disabled by defaultSimon Ser
2023-05-15backend_destroy: Similiar logic like DRM backendTobias Predel
In the logic of the DRM backend in backend_destroy, wlr_backend_finish is called first, then the outputs are destroyed and then the display->destroy.link is removed from the list. This commit applies the same order to the headless backend.

2022-02-22interfaces: remove wlr_input_device_implSimon Zeni
2022-02-21backend/headless: remove unused wlr_headless_input_deviceSimon Zeni
2021-11-25backend/headless: drop wlr_headless_backend_create_with_rendererSimon Ser
The headless backend no longer needs a parent renderer: it no longer needs to return it in wlr_backend_impl.get_renderer, nor does it need to return its DRM FD in wlr_backend_impl.get_drm_fd. Drop this function altogether since it now behaves exactly like wlr_headless_backend_create.
2021-11-25backend/headless: stop picking a DRM FDSimon Ser
Sometimes the headless backend is used standalone with the Pixman renderer, sometimes it's used together with another backend which has already picked a DRM FD. In both of these cases it doesn't make sense to pick a DRM FD. Broadly speaking the headless backend doesn't really care which DRM device is used for the buffers it receives. So it doesn't really make sense to tie it to a particular DRM device. Let the backend users (e.g. wlr_renderer_autocreate) open an arbitrary DRM FD as needed instead.
2021-11-23input-device: remove wlr_input_device.linkSimon Ser
This field's ownership is unclear: it's in wlr_input_device, but it's not managed by the common code, it's up to each individual backend to use it and clean it up. Since this is a backend implementation detail, move it to the backend-specific structs.
2021-11-18backend/headless: don't store the parent rendererSimon Zeni
2021-09-30backend: create renderer and allocator in wlr_backend_autocreateSimon Ser
Instead of ensuring the renderer and allocator are initialized in each backend, do it in wlr_backend_autocreate. This allows compositors to create backends without any renderer/allocator if they side-step wlr_backend_autocreate. Since the wlr_backend_get_renderer and backend_get_allocator end up calling wlr_renderer_autocreate and wlr_allocator_autocreate, it sounds like a good idea to centralize all of the opimionated bits in one place.
2021-08-25Move allocator stuff into new directorySimon Ser
Add render/allocator/ and include/render/allocator/ to hold everything allocator-related.
2021-07-01buffer: make enum wlr_buffer_cap publicSimon Ser
Custom backends and renderers need to implement wlr_backend_impl.get_buffer_caps and wlr_renderer_impl.get_render_buffer_caps. They can't if enum wlr_buffer_cap isn't made public.
2021-06-07backend/headless: remove swapchainSimon Ser
Rely on wlr_output's generic swapchain support instead of creating our own. The headless output now simply keeps a reference to the front buffer and does nothing else.
2021-05-21backend/headless: use common renderer and allocatorSimon Ser
Instead of managing our own renderer and allocator, let the common code do it. Because wlr_headless_backend_create_with_renderer needs to re-use the parent renderer, we have to hand-roll some of the renderer initialization.
2021-05-21backend: introduce wlr_backend_finishSimon Ser
This new functions cleans up the common backend state. While this currently only emits the destroy signal, this will also clean up the renderer and allocator in upcoming patches.
2021-04-29backend/headless: dup DRM FD in wlr_headless_backend_create_with_rendererSimon Ser
We were not dup'ing the DRM FD coming from wlr_renderer_get_drm_fd, resulting in a double-close on backend destroy.
2021-04-28backend: use wlr_allocator_autocreateSimon Zeni

2021-04-15render: rename get_dmabuf_render_formats into get_render_formatsSimon Zeni
2021-01-17backend/headless: create renderer after wlr_backend_initSimon Ser
We were calling wlr_renderer_autocreate before wlr_backend_init, which caused a NULL dereference on wlr_backend.impl.

2021-01-07backend: remove wlr_egl from all backendsSimon Zeni
2021-01-06render: remove EGL config and visual from wlr_renderer_autocreateSimon Ser
This isn't used anymore by any backend. Some examples still provide an EGL config to wlr_egl_init, so we can't drop it yet there.
2020-12-30Remove wlr_create_renderer_func_tSimon Ser
This callback allowed compositors to customize the EGL config used by the renderer. However with renderer v6 EGL configs aren't used anymore. Instead, buffers are allocated via GBM and GL FBOs are rendered to. So customizing the EGL config is a no-op.
2020-12-16backend/headless: select the rendering device ourselvesSimon Ser
Backends will eventually stop creating their renderer. To prepare for this, stop using EGL_PLATFORM_SURFACELESS_MESA in the headless renderer. Pick a render node using libdrm. The new allocator/renderer creation logic looks very much like what will end up in common code.
2020-12-15backend: use fcntl(F_DUPFD_CLOEXEC) instead of dupSimon Ser
This makes sure the CLOEXEC flag is set on the dup'ed FD.
2020-12-07backend/headless: create a config-less EGL contextSimon Ser
2020-11-30backend/headless: use a format suitable for renderingSimon Ser
When allocating buffers, use a format suitable for rendering. This avoids picking a format that won't work.
2020-11-15backend/headless: switch to wlr_swapchainSimon Ser
2020-05-02backend/headless: handle renderer destroySimon Ser
When the headless backend uses an already-existing renderer, it doesn't have ownership over the renderer. When the renderer is destroyed, the headless backend needs to destroy itself.
2020-04-22backend/headless: add wlr_headless_backend_create_with_rendererSimon Ser
This allows one to create a headless backend with an existing renderer.
2020-04-22backend/headless: use FBOs instead of pbuffersSimon Ser
2020-04-09backend: set EGL_RENDERABLE_TYPE and EGL_SURFACE_TYPESimon Ser
Ensure these are set to the correct value.
2020-01-12render/egl: remove SURFACELESS_MESA special caseSimon Ser
Users can just pass EGL_DEFAULT_DISPLAY themselves.
2019-12-20Refactor EGL/GL API loadingSimon Ser
Remove glapi.sh code generation, replace it with hand-written loading code that checks extension strings before calling eglGetProcAddress. The GLES2 renderer still uses global state because of: - {PUSH,POP}_GLES2_DEBUG macros - wlr_gles2_texture_from_* taking a wlr_egl instead of the renderer
2018-11-10render: correctly set EGL_RENDERABLE_TYPEemersion
This should be set to EGL_OPENGL_ES2_BIT. Also fixes EGL config attributes in the headless and X11 backends.

2018-05-25backends: implement custom EGL and renderer initializationIlia Bozhinov
Compositors now have more control over how the backend creates its renderer. Currently all backends create an EGL/GLES2 renderer, so the necessary attributes for creating the context are passed to a user-provided callback function. It is responsible for initializing provided wlr_egl and to return a renderer. On fail, return 0. Fixes #987
