2022-08-30output: fail commits if adaptive sync cannot be enabledSimon Ser
Previously, adaptive sync was just a hint and wouldn't make any atomic commit fail if the backend didn't support it. The main reason is wlr_output_test wasn't supported at the time. Now that we have a way for compositors to test whether a change can work, let's remove the exception for adaptive sync and convert it to a regular output state field.

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.
2021-11-19output: 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.
2021-07-29output: drop wlr_output_impl.{attach,rollback}_renderSimon Ser

2021-06-20backend: add output state allow-listsSimon Ser
Right now, when a new output state field is added, all backends by default won't reject it. This means we need to add new checks to each and every backend when we introduce a new state field. Instead, introduce a bitmask of supported output state fields in each backend, and error out if the user has submitted an unknown field. Some fields don't need any backend involvment to work. These are listed in WLR_OUTPUT_STATE_BACKEND_OPTIONAL as a convenience.
2021-06-07output: make attach_render and rollback_render optionalSimon Ser
If these aren't provided by the backend, allocate a swapchain for the output.
2021-06-07output: add get_primary_formats to interfaceSimon Ser
This function returns the set of formats the backend can use for the primary buffer. It can be used to allocate a buffer suitable for scan-out.
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.

2020-06-19output: rename impl->rollback to rollback_renderSimon Ser
The output backend API is now mostly state-less thanks to the atomic hooks (commit and test). There is one exception though: attach_render. This function makes the rendering context current. However sometimes the compositor might decide not to render after attach_render (e.g. when there's nothing new to render to the back buffer). Thus wlr_output_rollback has been introduced to revert the pending state. Because the output backend API is mostly state-less, the only thing wlr_output_impl.rollback needs to do is revert the current rendering context. Rename the function to rollback_render to make this clear. Add a check in the common wlr_output code to only call rollback_render when attach_buffer has been previously called. On the long term, we'll be able to remove attach_render and rollback_render together.
2020-05-14output: make wlr_output_set_gamma atomicSimon Ser
wlr_output_set_gamma is now double-buffered and applies the gamma LUT on the next output commit.
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
2020-04-08Add 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.

2020-04-08output: 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
2020-03-04output: 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

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
2019-08-07Revert "output: atomic mode"Rouven Czerwinski
This reverts commit ee5f98ad49fed0439f3313ec685307831d1d1d05. This intoduced problems where outputs could not be turned off because they had flips pending.
2019-08-02output: 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.

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.
