2020-05-01Fix error when reconnecting external displayWill Daly
Reconnecting an external display fails on initial page-flip. This occurs when the pageflip_pending flag has been set on the connector at the time the monitor is removed. Once the connector's CRTC has been deallocated, page_flip_handler cannot find the connector by its crtc_id, so pageflip_pending will remain set. This causes initialization to fail when the monitor is reconnected with the error messages: Skipping pageflip on output 'X' Failed to initialize renderer on connector 'X': initial page-flip failed To fix this problem, clear the pageflip_pending flag when cleaning up the connector.
2020-04-29backend/drm: strip alpha channel if necessarySimon Ser
Some primary planes don't support ARGB8888, they only support XRGB8888 (for instance on older Intel hardware). The DRM backend would fail to initialize. When that's the case, try to allocate buffers without an alpha channel.
2020-04-28backend/drm: don't allow legacy to use direct scanoutScott Anderson
2020-04-28backend/drm: move atomic cursor code into pageflip codeScott Anderson
It makes sense to construct as much atomic state as possible in the same place, so it doesn't get lost if we "reset" it.
2020-04-28backend/drm: don't have fallback atomic commitsScott Anderson
This is just doing atomic incorrectly.
2020-04-28backend/drm: introduce wlr_drm_fbScott Anderson
This is a type which manages gbm_surfaces and imported dmabufs in the same place, and makes the lifetime management between the two shared. It should lead to easier to understand code, and fewer special cases. This also contains a fair bit of refactoring to start using this new type. Co-authored-by: Simon Ser <contact@emersion.fr>
2020-04-10output: check for buffer size compatibility in common codeSimon Ser
Instead of checking for buffer size compatibility in each backend, centralize the check in wlr_output itself.
2020-04-10output: fix blurred hw cursors with fractional scalingSimon Ser
The scaling factor was being implicitly cast to an int. Closes: https://github.com/swaywm/sway/issues/4927
2020-04-09backend: set EGL_RENDERABLE_TYPE and EGL_SURFACE_TYPESimon Ser
Ensure these are set to the correct value.
2020-04-08Add wlr_output_impl.rollbackSimon Ser
Most of the pending output state is not forwarded to the backend prior to an output commit. For instance, wlr_output_set_mode just stashes the mode without calling any wlr_output_impl function. wlr_output_impl.commit is responsible for applying the pending mode. However, there are exceptions to this rule. The first one is wlr_output_attach_render. It won't go away before renderer v6 is complete, because it needs to set the current EGL surface. The second one is wlr_output_attach_buffer. wlr_output_impl.attach_buffer is removed in [1]. When wlr_output_rollback is called, all pending state is supposed to be cleared. This works for all the state except the two exceptions mentionned above. To fix this, introduce wlr_output_impl.rollback. Right now, the backend resets the current EGL surface. This prevents GL commands from affecting the output after wlr_output_rollback. This patch is required for FBO-based outputs to work properly. The compositor might be using FBOs for its own purposes [2], having leftover FBO state can have bad consequences.

2020-04-08backend: reset EGL surface after buffer swapSimon Ser
This prevents GL commands to affect a previously current EGL surface after a buffer swap.
2020-04-08output: check buffer in wlr_output_testSimon Ser
Check that buffer can be scanned out in wlr_output_test instead of wlr_output_attach_buffer. This allows the backend to have access to the whole pending state when performing the check. This brings the wlr_output API more in line with the KMS API. This removes the need for wlr_output_attach_buffer to return a value, and for wlr_output_impl.attach_buffer.
2020-04-08output: introduce wlr_output_testSimon Ser
2020-04-02buffer: add a release eventSimon Ser
Consumers call wlr_buffer_lock. Once all consumers are done with the buffer, only the producer should have a reference to the buffer. In this case, we can release the buffer (and let the producer re-use it).

2020-03-06backend/drm: add support for adaptive_sync_enabledSimon Ser
The vrr_capable and VRR_ENABLED properties are used.
2020-03-04output: remove wlr_output_impl.schedule_frameSimon Ser
This function allowed backends to provide a custom function for frame scheduling. Before resuming the rendering loop, the DRM and Wayland backends would wait for vsync. There isn't a clear benefit of doing this. The only upside is that we get more stable timings: the delay between two repaints doesn't change too much and is close to a mutliple of the refresh rate. However this introduces latency, especially when a client misses a frame. For instance a fullscreen game missing vblank will need to wait more than a whole frame before being able to display new content. This worst case scenario happens as follows: - Client is still rendering its frame and cannot submit it in time - Deadline is reached - Compositor decides to stop the rendering loop since nothing changed on screen - Client finally manages to render its frame, submits it - Compositor calls wlr_output_schedule_frame - DRM backend waits for next vblank - The wlr_output frame event is fired, compositor draws new content on screen - On the second next vblank, the new content reaches the screen With this patch, the wlr_output frame event is fired immediately when the client submits its late frame. This change also makes it easier to support variable refresh rate, since VRR is all about being able to present too-late frames earlier. References: https://github.com/swaywm/wlroots/issues/1925
2020-01-24backend/drm: remove overzealous finish_drm_surfaceRouven Czerwinski
The previous PR was overzealous in adding a finish_drm_surface call which was also done by the caller. Remove the call and also move the comment to the correct code location.
2020-01-24backend/drm: add env variable to disable modifiersRouven Czerwinski
In some cases modesets fail if the planes are initialized with modifiers. Since in this case possibly all planes need to reinitialized, which is not possible in the current wlroots design, add an environment variable for affected users.
2020-01-17backend/drm: prevent outputs from being destroyed on commitSimon Ser
This would happen if initializing the renderer fails. Instead, we just mark the output as disabled. References: https://github.com/swaywm/sway/pull/4917
2019-12-30backend/drm: don't modeset with a NULL mode after TTY switchSimon Ser
This fixes a segfault in drm_connector_set_mode (mode = NULL). This happens because we set wlr_output.enabled to true if the connector is attached to the CRTC. When the user disables an output in the wlroots-based compositor, switches to another VT (enabling the output), then switches back, wlroots sets wlr_output.enabled to true but wlr_output.current_mode is NULL. We should consider not reading properties from KMS after a TTY switch, disabling all connectors. However this may result in flickering (outputs being disabled then re-enabled). Closes: https://github.com/swaywm/wlroots/issues/1874

2019-12-29output: add descriptionSimon Ser
wlr_output.description is a string containing a human-readable string identifying the output. Compositors can customise it via wlr_output_set_description, for instance to make the name more user-friendly. References: https://github.com/swaywm/wlroots/issues/1623
2019-12-23meson: Various improvementsScott Anderson
Bumps minimum version to 0.51.0 - Remove all intermediate static libraries. They serve no purpose and are just add a bunch of boilerplate for managing dependencies and options. It's now managed as a list of files which are compiled into libwlroots directly. - Use install_subdir instead of installing headers individually. I've changed my mind since I did that. Listing them out is annoying as hell, and it's easy to forget to do it. - Add not_found_message for all of our optional dependencies that have a meson option. It gives some hints about what option to pass and what the optional dependency is for. - Move all backend subdirectories into their own meson.build. This keeps some of the backend-specific build logic (especially rdp and session) more neatly separated off. - Don't overlink example clients with code they're not using. This was done by merging the protocol dictionaries and setting some variables containing the code and client header file. Example clients now explicitly mention what extension protocols they want to link to. - Split compositor example logic from client example logic. - Minor formatting changes
2019-12-20backend/drm: print preferred modeRouven Czerwinski
While printing the supported output modes, annotate the preferred mode.
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

2019-12-05backend/drm: fix segfault in init_drm_surfaceSimon Ser
When surf->gbm was previously set, we destroy it without setting it to NULL. Later on, we only create the GBM surface if surf->gbm is NULL. This result in a use-after-free when we start using surf->gbm.

2019-08-07Revert "output: atomic mode"Rouven Czerwinski
This reverts commit ee5f98ad49fed0439f3313ec685307831d1d1d05. This intoduced problems where outputs could not be turned off because they had flips pending.
2019-08-03backend/drm: destroy output immediatelyRouven Czerwinski
Instead of waiting for the next pageflip, destroy the output immediately since we can now handle flips for outputs which no longer exist. Also demote the missing crtc on flip to debug. Fixes #1739
2019-08-02output: atomic mode, enabled, scale and transformSimon Ser
This commit makes more output properties (mode, enabled, scale and transform) atomic. This means that they are double-buffered and only applied on commit. Compositors now need to call wlr_output_commit after setting any of those properties. Internally, backends still apply properties sequentially. The behaviour should be exactly the same as before. Future commits will update some backends to take advantage of the atomic interface. Some backends are non-atomic by design, e.g. the X11 backend or the legacy DRM backend. Updates: https://github.com/swaywm/wlroots/issues/1640
2019-07-27Remove all wayland-server.h includesSimon Ser
The documentation for wayland-server.h says: > Use of this header file is discouraged. Prefer including > wayland-server-core.h instead, which does not include the server protocol > header and as such only defines the library PI, excluding the deprecated API > below. Replacing wayland-server.h with wayland-server-core.h allows us to drop the WL_HIDE_DEPRECATED declaration.
2019-06-27backend: drm: switch to pageflip_handler_2Rouven Czerwinski
atomic and legacy now both pass the backend as the user data for the pageflip event. We than retrieve the correct connector by matching on the crtc_id passed to the page_flip_handler2. Wlroots also requires the DRM_CRTC_IN_VBLANK_EVENT capability now. Fixes #1297
2019-06-24backend/drm: Exit-early if 0 crtcsScott Anderson
This fixes an assertion failure if we're using a device that has 0 crtcs as a renderer. This would happen on some laptops with discrete GPUs.
2019-06-22backend/drm: Simplify object matching codeScott Anderson
We originally used match_obj on planes, but this was largely unnecessary. Instead, this assigns planes statically at startup.
2019-06-16output: remove wlr_output_impl.transformSimon Ser
The backend doesn't need to handle transform changes, since everything is done in software. In fact, all of the implementations were all identical and just set the transform. We could add support for hardware transforms, but: - This would require a different field (something like hardware_transform) - Not all combinations are possible because there often are hardware limitations - The Wayland protocol isn't ready for this (in particular xdg-output, see [1]) This belongs to a different patch series anyway.
