2021-09-27backend/wayland: send hold gesture eventsJosé Expósito
Receive hold gesture events using a Wayland listiner and emit the appropiate wlr_pointer signal.
2021-09-27backend/libinput: send hold gesture eventsJosé Expósito
Receive hold gesture events from libinput and emit the appropiate wlr_pointer signal.
2021-09-21backend/drm: add support for panel orientationSimon Ser
Expose the panel orientation with wlr_drm_connector_get_panel_orientation. Leave it to the compositor to consume this information and configure the output accordingly. Closes: https://github.com/swaywm/wlroots/issues/1581
2021-09-08backend/drm: implement drm lease functionSimon Zeni
2021-09-07backend/drm: drop wlr_drm_connector.desired_modeSimon Ser
Previously used by attempt_enable_needs_modeset, but this has been dropped in the previous commit.
2021-09-07backend/drm: introduce wlr_drm_connector_stateSimon Ser
Previously, we were copying wlr_output_state on the stack and patching it up to be guaranteed to have a proper drmModeModeInfo stored in it (and not a custom mode). Also, we had a bunch of helpers deriving DRM-specific information from the generic wlr_output_state. Copying the wlr_output_state worked fine so far, but with output layers we'll be getting a wl_list in there. An empty wl_list stores two pointers to itself, copying it on the stack blindly results in infinite loops in wl_list_for_each. To fix this, rework our DRM backend to stop copying wlr_output_state, instead add a new struct wlr_drm_connector_state which holds both the wlr_output_state and additional DRM-specific information.
2021-09-07backend/drm: rename enum wlr_drm_connector_state to statusSimon Ser
"state" is easily confused with wlr_output_state.
2021-08-25backend/drm: introduce wlr_drm_bo_handle_tableSimon Ser
Using GBM to import DRM dumb buffers tends to not work well. By using GBM we're calling some driver-specific functions in Mesa. These functions check whether Mesa can work with the buffer. Sometimes Mesa has requirements which differ from DRM dumb buffers and the GBM import will fail (e.g. on amdgpu). Instead, drop GBM and use drmPrimeFDToHandle directly. But there's a twist: BO handles are not ref'counted by the kernel and need to be ref'counted in user-space [1]. libdrm usually performs this bookkeeping and is used under-the-hood by Mesa. We can't re-use libdrm for this task without using driver-specific APIs. So let's just re-implement the ref'counting logic in wlroots. The wlroots implementation is inspired from amdgpu's in libdrm [2]. Closes: https://github.com/swaywm/wlroots/issues/2916 [1]: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/110 [2]: https://gitlab.freedesktop.org/mesa/drm/-/blob/1a4c0ec9aea13211997f982715fe5ffcf19dd067/amdgpu/handle_table.c
2021-08-18backend/drm: add support for FB_DAMAGE_CLIPSSimon Ser
This allows the kernel to access our buffer damage. Some drivers can take advantage of this, e.g. for PSR2 panels (Panel Self Refresh) or for transfer over USB. Closes: https://github.com/swaywm/wlroots/issues/1267
2021-08-17backend/drm: use addon for wlr_drm_fbSimon Ser
2021-07-28backend/drm: stop initializing renderer for parent backendSimon Ser
Unless we're dealing with a multi-GPU setup and the backend being initialized is secondary, we don't need a renderer nor an allocator. Stop initializing these.
2021-07-28backend/drm: drop drm_surface_{make,unset}_currentSimon Ser
2021-07-28backend/drm: remove primary swapchainSimon Ser
We can't nuke it completely, we still need it for multi-GPU.
2021-07-20backend/drm: stop restoring CRTCs on exitSimon Ser
This is the cause of the spurious "drmHandleEvent failed" messages at exit. restore_drm_outputs calls handle_drm_event in a loop without checking whether the FD is readable, so drmHandleEvent ends up with a short read (0 bytes) and returns an error. The loop's goal is to wait for all queued page-flip events to complete, to allow drmModeSetCrtc calls to succeed without EBUSY. The drmModeSetCrtc calls are supposed to restore whatever KMS state we were started with. But it's not clear from my PoV that restoring the KMS state on exit is desirable. KMS clients are supposed to save and restore the (full) KMS state on VT switch, but not on exit. Leaving our KMS state on exit avoids unnecessary modesets and allows flicker-free transitions between clients. See [1] for more details, and note that with Pekka we've concluded that a new flag to reset some KMS props to their default value on compositor start-up is the best way forward. As a side note, Weston doesn't restore the CRTC by does disable the cursor plane on exit (see drm_output_deinit_planes, I still think disabling the cursor plane shouldn't be necessary on exit). Additionally, restore_drm_outputs only a subset of the KMS state. Gamma and other atomic properties aren't accounted for. If the previous KMS client had some outputs disabled, restore_drm_outputs would restore a garbage mode. [1]: https://blog.ffwll.ch/2016/01/vt-switching-with-atomic-modeset.html
2021-07-12backend/headless: remove wlr_output_impl.export_dmabufSimon Ser
This is now provided by the generic wlr_output implementation.
2021-07-09backend/drm: remove backend arg from wlr_drm_interface.crtc_commitSimon Ser
The callee can just get it from the wlr_drm_connector.
2021-07-09backend/drm: add test_only arg to wlr_drm_interface.crtc_commitSimon Ser
Right now callers of drm_crtc_commit need to check whether the interface is legacy or atomic before passing the TEST_ONLY flag. Additionally, the fallbacks for legacy are in-place in the common code. Add a test_only arg to the crtc_commit hook. This way, there's no risk to pass atomic-only flags to the legacy function (add an assert to ensure this) and all of the legacy-specific logic can be put back into legacy.c (done in next commit).

2021-07-06move wlr_box from /types to /utilSimon Zeni
2021-07-01backend/libinput: stop using wlr_list internallySimon Ser
2021-06-07backend/wayland: remove swapchainSimon Ser
Rely on wlr_output's generic swapchain handling.
2021-06-07backend/x11: remove swapchainSimon Ser
Rely on wlr_output's generic swapchain handling. We still need a renderer for cursor readback, sadly.
2021-06-07backend/x11: implement get_dmabuf_primary_formatsSimon Ser
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.
2021-06-02backend/drm: move cursor fields to wlr_drm_connectorSimon Ser
Doesn't make a lot of sense to split the cursor fields between wlr_drm_plane and wlr_drm_connector. Let's just move everything to wlr_drm_connector.
2021-06-02output: take a wlr_buffer in set_cursorSimon Ser
Instead of passing a wlr_texture to the backend, directly pass a wlr_buffer. Use get_cursor_size and get_cursor_formats to create a wlr_buffer that can be used as a cursor. We don't want to pass a wlr_texture because we want to remove as many rendering bits from the backend as possible.
2021-06-02backend/drm: remove format arg from drm_plane_init_surfaceSimon Ser
This was always set to ARGB8888.
2021-06-02backend/drm: implement get_cursor_formats and get_cursor_sizeSimon Ser
2021-05-21backend/x11: use common renderer and allocatorSimon Ser
Instead of managing our own renderer and allocator, let the common code do it.
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/wayland: use common renderer and allocatorSimon Ser
Instead of managing our own renderer and allocator, let the common code do it.
2021-05-21backend: automatically create allocatorSimon Ser
Introduce a new backend_get_allocator function that automatically creates an allocator for the backend if the backend has a renderer.
2021-04-29backend/drm: introduce drm_connector_commit_stateSimon Ser
Backend-initiated mode changes can use this function instead of going through drm_connector_set_mode. drm_connector_set_mode becomes a mere drm_connector_commit_state helper.
2021-04-29backend/drm: remove mode arg from drm_connector_set_modeSimon Ser
All of the information is in wlr_output_state.
2021-04-29backend/drm: remove wlr_drm_crtc_state.modeSimon Ser
Replace it with drm_connector_state_mode, which computes the mode from the wlr_output_state to be applied.
2021-04-29backend/drm: remove wlr_drm_crtc_state.activeSimon Ser
Replace it with drm_connector_state_active, which figures out whether the connector is active depending on the wlr_output_state to be applied.
2021-04-29backend/drm: remove wlr_drm_crtc.pending_modesetSimon Ser
Replace it with a new drm_connector_state_is_modeset function that decides whether a modeset is necessary directly from the wlr_output_state which is going to be applied.
2021-04-29backend/drm: take wlr_output_state as arg in commit callersSimon Ser
Instead of relying on wlr_output.pending to be empty when performing backend-initiated CRTC commits, use a zero wlr_output_state.
2021-04-29backend/drm: take wlr_output_state as arg in crtc_commitSimon Ser
Stop assuming that the state to be applied is in output->pending in crtc_commit. This will allow us to remove ephemeral fields in wlr_drm_crtc, which are used scratch fields to stash temporary per-commit data.
2021-04-28backend: introduce backend_get_buffer_capsSimon Zeni
2021-04-28render/gbm_allocator: make wlr_gbm_allocator_create return a wlr_allocatorSimon Zeni
2021-04-27backend/drm: destroy backend on udev remove eventSimon Ser
Any use of the DRM FD after the remove event results in a "Permission denied" error.
2021-04-27backend/drm: destroy when parent is destroyedSimon Ser
2021-04-20backend/x11: add support for shm buffersTadeo Kondrak
2021-04-17backend/wayland: add support for wl_shm buffersSimon Ser
2021-04-14backend/session: Remove session_implKenny Levinsen
libseat provides all session functionality, so there is no longer need for a session backend abstraction. The libseat device ID, seat handle and event loop handle are moved to the main wlr_session and wlr_device structs.
2021-04-14backend/session: Remove direct backendKenny Levinsen
This is instead delegated to libseat.
2021-04-12backend: move get_drm_fd to public interfaceRoman Gilg
The get_drm_fd was made available in an internal header with a53ab146f. Move it now to the public header so consumers opting in to the unstable interfaces can make use of it.
2021-04-09Remove WLR_HAS_XCB_ERRORSSimon Ser
wlroots' dependency on this library doesn't change the features exposed to compositors. It's purely a wlroots implementation detail. Thus downstream compositors shouldn't really care about it. Introduce an "internal_features" dictionary to store the status of such internal dependencies.
2021-04-06Use absolute paths in include in header fileszccrs
To unify the code style of the project, absolute paths have been used in some places, such as '#include "render/allocator.h"' in "render/gbm_allocator.h". Except for include the wayland protocol headers should be consistent.
