2021-12-07linux-dmabuf-v1: add per-surface feedbackSimon Ser
2021-12-07linux-dmabuf-v1: implement v4Simon Ser
Implement a basic version of linux-dmabuf-unstable-v1 version 4. Only default hints are implemented. The new wlr_linux_dmabuf_feedback_v1 data structure will allow compositors to define their own custom hints in the future. This data structure makes it easy to describe feedback metadata. It's converted to a "compiled" form suitable for marshalling over the Wayland socket via feedback_compile.
2021-12-07render: add wlr_renderer_init_wl_shmSimon Ser
This allows compositors to initialize wl_shm without initializing other globals like linux-dmabuf.
2021-12-03output: drop front_bufferSimon Ser
This lets backends immediately release committed buffers if they want to.
2021-12-03output: add wlr_output_event_commit.bufferSimon Ser
This allows output commit listeners to access the newly committed buffer. Currently wlr_output.front_buffer is used but it'll get removed in the next commit.
2021-12-03render/drm-format-set: add wlr_drm_format_set_intersectSimon Ser
This intersects two DRM format sets. This is useful for implementing DMA-BUF feedback in compositors, see e.g. the Sway PR [1]. [1]: https://github.com/swaywm/sway/pull/6313
2021-12-02render/egl: improve modifier support detectionSimon Ser
Support for EXT_image_dma_buf_import_modifiers doesn't necessarily indicate support for modifiers. For instance, Mesa will advertise EXT_image_dma_buf_import_modifiers for all drivers. This is a trick to allow EGL clients to enumerate supported formats (something EXT_image_dma_buf_import is missing). For more information, see [1]. Add a new wlr_egl.has_modifiers flag which indicates whether modifiers are supported. It's set to true if any eglQueryDmaBufModifiersEXT query returned a non-empty list. Use that flag to figure out whether the buffer modifier should be passed to the EGL implementation on import. [1]: https://github.com/KhronosGroup/EGL-Registry/issues/142
2021-12-01render/egl: add wlr_egl_create_with_contextSimon Ser
This allows creating a wlr_egl from an already-existing EGL display and context. This is useful to allow compositors to choose the exact EGL initialization parameters.
2021-12-01render/egl: store IMG_context_priority in wlr_eglSimon Ser
The next commit will split extension lookup and context initialization.
2021-11-30scene: add wlr_scene_get_scene_outputSimon Ser
This allows getting a wlr_scene_output from a wlr_output. Since an output can only be added once to a scene-graph there's no ambiguity. This is useful for compositors using wlr_scene_attach_output_layout: the output layout integration automatically creates a scene-graph output for each wlr_output added to the layout.
2021-11-30output: add wlr_output_get_primary_formatsSimon Ser
This allows compositors to get primary formats without manually calling wlr_output_impl.get_primary_formats. For example, the Sway patch for linux-dmabuf feedback [1] needs this. [1]: https://github.com/swaywm/sway/pull/6313
2021-11-30output: fix typo in wlr_output_impl.get_primary_formats docsSimon Ser
The buffer capabilities indicate whether the formats returned are for DMA-BUFs or shared memory buffers.
2021-11-26render: add DMA-BUF docsSimon Ser
Document some of the assumptions for DMA-BUF buffer sharing and modifiers.
2021-11-26render/drm_format_set: add wlr_drm_format_hasSimon Ser
2021-11-25scene: add wlr_scene_xdg_surface_createSimon Ser
This allows compositors to easily add an xdg_surface to the scene-graph while retaining the ability to unconstraint popups and decide their final position. Compositors can handle new popups with the wlr_xdg_shell.new_surface event, get the parent scene-graph node via wlr_xdg_popup.parent.data, create a new scene-graph node via wlr_scene_xdg_surface_tree_create, and unconstraint the popup if they want to.
2021-11-25backend: remove noop backendSimon 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.
2021-11-22backend/wayland: report parent presentation clockSimon Ser
There's no guarantee that the parent Wayland compositor uses CLOCK_MONOTONIC for reporting presentation timestamps, they could be using e.g. CLOCK_MONOTONIC_RAW or another system-specific clock. Forward the value via wlr_backend_impl.get_presentation_clock. References: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3254#note_1143061
2021-11-22linux-dmabuf-v1: hide wlr_linux_buffer_params_v1Simon Ser
The parameters are used when the client is in the process of building a buffer. There's no reason why this internal implementation detail should be exposed in our public header.
2021-11-19backend/drm: scan leases on ueventSimon Ser
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3181
2021-11-19drm-lease-v1: listen to lease destroy eventSimon Ser
2021-11-19backend/drm: introduce wlr_drm_leaseSimon Ser
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3183
2021-11-19Introduce WLR_DEVICE_LEASE eventsSimon Ser
This will allow the DRM backend to reload its lessee list.
2021-11-19output: Add function to set preferred render formatManuel Stoeckl
This change introduces new double buffered state to the wlr_output, corresponding to the buffer format to render to. The format being rendered to does not control the bit depth of colors being sent to the display; it does generally determine the format with which screenshot data is provided. The DRM backend _may_ sent higher bit depths if the render format depth is increased, but hardware and other limitations may apply.
2021-11-19output: lift up output format fallback logicManuel Stoeckl
This makes it possible for the two functions using output_pick_format (output_pick_cursor_format and output_create_swapchain) to select different buffer formats.
2021-11-18backend: remove wlr_backend_get_rendererSimon Zeni
2021-11-18backend/headless: don't store the parent rendererSimon Zeni
2021-11-18backend: remove backend_get_allocatorSimon Zeni

2021-11-17Improve wlr_drm_format documentationDemi Marie Obenour
A wlroots user can easily get confused and think that `cap` refers to wlroots buffer capabilities, not array capacity.
2021-11-17Remove support for DMA-BUF flagsSimon Ser
They are never used in practice, which makes all of our flag handling effectively dead code. Also, APIs such as KMS don't provide a good way to deal with the flags. Let's just fail the DMA-BUF import when clients provide flags.
2021-11-09render/allocator: make wlr_allocator part of the public APISimon Zeni
2021-11-08text-input: fix type of send_preedit_string() argsIsaac Freund
The protocol uses a signed integer here, which is also what the wlr_input_method_v2_preedit_string struct provides to compositors from the input method protocol. Sway currently just passes those int32_t values directly to this function leading to an implicit conversion.
2021-11-08output: drop wlr_output_export_dmabufSimon Ser
Callers can access output->front_buffer instead.
2021-11-02backend/drm: handle per-connector hotplug eventsSimon Ser
When a connector ID is specified in a hotplug event, don't scan all connectors. Only scan the connector that has changed.
2021-11-02backend/session: introduce wlr_device_change_eventSimon Ser
This struct contains additional information for session device change events, such as the DRM connector ID that has changed.
2021-11-02xwayland: add support for -noTouchPointerEmulationSimon Ser
This allows compositors to handle touch pointer emulation manually, instead of having Xwayland do it [1]. [1]: https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/691
2021-10-31backend/wayland: use xdga client activationRonan Pigott
2021-10-31xdg-activation-v1: add data field and emit token destroy eventsRonan Pigott
The data field is useful to track metadata about a token. The destroy events are useful for compositors that track application startup to let them know they can stop doing that.
2021-10-31xdg-activation-v1: enable compositors to request their own tokensRonan Pigott
These new functions allow a compositor to request new managed tokens without participating in the xdg-activation procedure as a wayland client. This enables the compositor itself to behave as a launcher application.
2021-10-29backend/drm: get rid of BO handle tableSimon Ser
The BO handle table exists to avoid double-closing a BO handle, which aren't reference-counted by the kernel. But if we can guarantee that there is only ever a single ref for each BO handle, then we don't need the BO handle table anymore. This is possible if we create the handle right before the ADDFB2 IOCTL, and close the handle right after. The handles are very short-lived and we don't need to track their lifetime. Because of multi-planar FBs, we need to be a bit careful: some FB planes might share the same handle. But with a small check, it's easy to avoid double-closing the same handle (which wouldn't be a big deal anyways). There's one gotcha though: drmModeSetCursor2 takes a BO handle as input. Saving the handles until drmModeSetCursor2 time would require us to track BO handle lifetimes, so we wouldn't be able to get rid of the BO handle table. As a workaround, use drmModeGetFB to turn the FB ID back to a BO handle, call drmModeSetCursor2 and then immediately close the BO handle. The overhead should be minimal since these IOCTLs are pretty cheap. Closes: https://github.com/swaywm/wlroots/issues/3164
2021-10-23output: split into multiple filesSimon Ser
This organizes the wlr_output implementation into separate files. This avoids having a single mega-file with lots of unrelated parts and makes it more obvious what the interactions between all the parts are. No functional changes, just moving code around.
2021-10-23scene: add support for direct scan-outSimon Ser
Check if only a single node intersects with the output viewport and all of its properties match. In this case, attempt direct scan-out.
2021-10-22scene: add wlr_scene_output_for_each_surfaceSimon Ser
This allows compositors to more easily implement sending wl_surface.frame callback done events.
2021-10-22presentation-time: remove unused fieldSimon Ser

2021-10-18render/vulkan: add Vulkan renderernyorain
This new renderer is implemented with the existing wlr_renderer API (which is known to be sub-optimal for some operations). It's not used by default, but users can opt-in by setting WLR_RENDERER=vulkan. The renderer depends on VK_EXT_image_drm_format_modifier and VK_EXT_physical_device_drm.
