2021-02-05backend/x11: use native cursorsIlia Mirkin
Fixes #2659
2021-01-24backend/drm: don't blit in drm_fb_importSimon Ser
Instead blit in drm_plane_lock_surface. This makes drm_fb_import simpler and better fits its name.
2021-01-24backend/drm: simplify drm_fb_lock_surfaceSimon Ser
Make it take a plane instead, and rename to drm_plane_lock_surface.
2021-01-24backend/drm: document wlr_drm_plane surface fieldsSimon Ser
2021-01-21backend/x11: keep track of exposed rects, add them to damage regionsIlia Mirkin
When we receive an Expose event, that means that we must redraw that region of the X11 window. Keep track of these regions with pixman regions, and merge them with the additional output damaged regions. Fixes #2670
2021-01-18backend/x11: set a blank cursor rather than hiding globallyIlia Mirkin
This actually simplifies the logic since we no longer have to wait for enter/leave events, and also improves the UX when e.g. handling a crash with gdb attached. See #2659
2021-01-17backend/drm: add support for the subconnector propertySimon Ser
The subconnector property indicates the connector sub-type. This is useful because that usually indicates what kind of connector the user has plugged in to their monitor, e.g. a DisplayPort-to-DVI cable will indicate a DVI subconnector. Also some laptops have non-DP connectors that are internally linked to a DP port on the GPU. Set the output description accordingly. See https://drmdb.emersion.fr/properties/3233857728/subconnector
2021-01-17backend/x11: add support for DRI3 1.0Simon Ser
Add fallbacks when DRI3 1.2 isn't supported. Closes: https://github.com/swaywm/wlroots/issues/2586
2021-01-16backend/headless: implement get_drm_fdSimon Ser
2021-01-16backend/x11: implement get_drm_fdSimon Ser
2021-01-16backend/wayland: implement get_drm_fdSimon Ser
2021-01-16backend: add get_drm_fd to interfaceSimon Ser
This function allows backends to return the DRM FD they are using. This will allow the allocator and the renderer to use the right device.
2021-01-10backend/wayland: use the EGL GBM platformSimon Ser
Just like other backends, use the EGL GBM platform. This will make it easier to move the allocator and renderer initialization out of the backends.
2021-01-10backend/drm: re-use FBsSimon Ser
Instead of importing buffers to GBM and KMS at each frame, cache them and re-use them while the wlr_buffer is alive. This is the same as [1] and [2] but for the DRM backend. [1]: https://github.com/swaywm/wlroots/pull/2538 [2]: https://github.com/swaywm/wlroots/pull/2539
2021-01-10backend/drm: only keep track of local bufferSimon Ser
Stop keeping track of buffers on the parent GPU when multi-GPU is used. This removes support for export_dmabuf on secondary GPUs, but renderer v6 will bring this back by managing the swapchains in wlr_output instead of the backends.
2021-01-10backend/drm: add wlr_drm_buf.local_wlr_bufSimon Ser
2021-01-10backend/drm: introduce drm_fb_createSimon Ser
2021-01-10backend/drm: make wlr_drm_plane.{pending,queued,current}_fb pointersSimon Ser
This will be useful once we start re-using wlr_drm_fb.
2021-01-07remove unnecessary egl includesSimon Zeni
2021-01-07backend: remove wlr_egl from all backendsSimon Zeni
2021-01-03backend/drm: stash pending page-flip CRTCSimon Ser
wlr_drm_connector.crtc may be updated by the DRM backend while a page-flip is pending. In this case, the page-flip handler won't be able to find the right wlr_drm_connector from the CRTC ID. Save the CRTC when performing a page-flip to ensure we always find the right connector when we get the event.
2020-12-31noop: listen to display destroy and destroy the backendIlia Bozhinov
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.
2020-12-30backend/drm: remove special linear case for cursor planeSimon Ser
We now properly mark the cursor plane's formats as linear-only, and we now have a version of wlr_drm_format_intersect that handles the case of linear-only formats and implicit modifiers. We can remove the special drm_plane_init_surface flag we had for cursor planes. This also allows us to use a non-linear layout for cursor planes on drivers that support it. Tested on amdgpu GFX9.
2020-12-28backend/x11: create per-window present event contextsSimon Ser
The Present protocol states: > An event context is associated with a specific window; using an existing > event context with a different window generates a Match error. Instead of a global event context, use a per-window event context to fix this error: [backend/x11/backend.c:608] X11 error: op Present (SelectInput), code Match (no extension), sequence 63, value 4194307 Closes: https://github.com/swaywm/wlroots/issues/2577
2020-12-27backend/x11: implement a real rendering loopSimon Ser
Instead of using a timer, rely on X11 Present events and send a new frame event when the parent compositor displays a new frame on screen. The previous attempt at doing this [1] hit issues with EGLSurface, but we don't use that anymore. [1]: https://github.com/swaywm/wlroots/pull/1894
2020-12-25backend/drm: make listener names more idiomaticSimon Ser
Use the "<object>_<event>" notation for listeners, use "handle_<listener>" for handlers.
2020-12-23backend/drm: use plural form for possible_crtcsSimon Ser
Make it clearer that this is a bitmask of CRTC indices.
2020-12-22backend/drm: remove drm_fb_acquireSimon Ser
Instead, import the buffer into GBM and KMS in drm_fb_import. Also move the multi-GPU copy there if necessary.
2020-12-22backend/drm: make drm_fb_acquire return a FB IDSimon Ser
2020-12-22backend/drm: drop export_drm_boSimon Ser
Not used anymore.
2020-12-21backend/x11: re-use pixmapsSimon Ser
Instead of re-importing a buffer each time we submit a frame, re-use the pixmaps if possible.
2020-12-21backend/wayland: re-use wl_buffersSimon Ser
Instead of re-importing a buffer each time we submit a new frame, re-use the wl_buffer objects if possible.
2020-12-18backend/drm: remove unused wlr_drm_plane.drm_formatSimon Ser
2020-12-18backend/drm: refactor wlr_output destructionSimon Ser
Instead of hand-rolling our own manual wlr_output cleanup function, rely on wlr_output_destroy to remove an output from the compositor's state.
2020-12-18backend/drm: introduce wlr_drm_connector.nameSimon Ser
The DRM backend is a little special when it comes to wlr_outputs: the wlr_drm_connectors are long-lived and are created even when no screen is connected. A wlr_drm_connector only advertises a wlr_output to the compositor when a screen is connected. As such, most of wlr_output's state is invalid when the connector is disconnected. We want to stop using wlr_output state on disconnected connectors. Introduce wlr_drm_connector.name which is always valid regardless of the connector status to avoid reading wlr_output.name when disconnected.
2020-12-18backend/drm: introduce wlr_drm_conn_logSimon Ser
Simplify and unify connector-specific logging with a new wlr_drm_conn_log macro. This makes it easier to understand which connector a failure is about, without having to explicitly integrate the connector name in each log message.
2020-12-17backend/drm: add wlr_drm_backend.nameSimon Ser
Save the DRM device name in a wlr_drm_backend field, so that we can easily use it for logging purposes.
2020-12-15backend/drm: add wlr_drm_connector.backendSimon Ser
This allows the DRM code to have direct access to the wlr_drm_backend without having to go through an upcast via get_drm_backend_from_backend.
2020-12-13backend/drm: stop using GBM flagsSimon Ser
gbm_bo_create_with_modifiers doesn't take GBM flags, so our wlr_gbm_allocator interface doesn't either. We were still internally using GBM flags in the DRM backend, leading to awkward back-and-forth conversions. The only flag passed to drm_plane_init_surface was GBM_BO_USE_LINEAR, so turn that into a bool to make sure other flags can't be passed in. Move the "force linear" logic out of init_drm_surface, because the supplied wlr_drm_format should already contain that information.
2020-12-13backend/x11: query modifiers supported by X11 serverSimon Ser
2020-12-13backend/x11: switch to wlr_swapchainSimon Ser
2020-12-13backend/wayland: use wlr_swapchain for cursor surfaceSimon Ser
2020-12-13backend/wayland: use wlr_swapchain for main surfaceSimon Ser
The cursor surface still uses a wl_egl_window. References: https://github.com/swaywm/wlroots/issues/1352
2020-12-09backend/drm: remove EGL configSimon Ser
Since we're using wlr_swapchain, we don't need to provide an EGL config.
2020-12-08backend/drm: stop tracking overlay planesSimon Ser
We don't do anything with them. Once we do, we can easily add this back.
2020-11-30backend/drm: "scaling mode" is a connector propertySimon Ser
It's not a CRTC property. Remove it altogether since it's unused.
2020-11-30backend/drm: rotation is a plane propertySimon Ser
"rotation" is a plane property, it's not a CRTC property. It was also missing from plane_info.
2020-11-24backend/x11: log errorsSimon Ser
Register an X11 error handler, and optionally use xcb-errors to print a detailed message.
2020-11-19backend/session: operate on wlr_deviceSimon Ser
Instead of operating on FDs in {open,close}_device, operate on wlr_devices. This avoids the device lookup in wlr_session and allows callers to have access to wlr_device fields. For now, we use it to remove wlr_session_signal_add and replace it with a more idiomatic wlr_session.events.change field. In the future, other events will be added.
