2022-10-13backend: use global output name countersSimon Ser
The output names must be globally unique per the Wayland spec, even if the compositor creates multiple backends of the same kind.

2022-05-30output: pass wlr_output_state to backendSimon Ser
Groundwork for the following commits. The goal is to allow users to specify their own wlr_output_state instead of wlr_output.pending.
2022-05-26output: turn make/model/serial into char *Simon Ser
This allows the make/model/serial to be NULL when unset, and allows them to be longer than the hardcoded array length. This is a breaking change: compositors need to handle the new NULL case, and we stop setting make/model to useless "headless" or "wayland" strings.
2022-05-10backend/headless: allow variable refresh rateSimon Ser
Instead of waking up each 16ms to emit a frame event, arm the timer when the output is committed. This allows the headless backend to idle when nothing changes on screen, and behaves similarly to the other backends.
2021-12-09Fix incorrect %zd formatting directivesSimon Ser
%zd is for ssize_t. For size_t we should use %zu.
2021-12-09output: introduce wlr_output_set_nameSimon Ser
wlroots picks names for all outputs, but it might be desirable for compositor to override it. For instance, Sway will use a headless output as a fallback in case no outputs are connected. Sway wants to clearly label the fallback output as such and label "real" headless outputs starting from HEADLESS-1.
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.

2021-07-12backend/headless: remove wlr_output_impl.export_dmabufSimon Ser
This is now provided by the generic wlr_output implementation.
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.
2021-06-07backend/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.
2021-05-21backend/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.
2021-02-18backend: add error messages in attach_render implsSimon Ser
2021-01-16render/gles2: make EGL context current in bind_bufferSimon Ser
Instead of requiring callers to manually make the EGL context current before binding a buffer and unsetting it after unbinding a buffer, do it inside wlr_renderer_bind_buffer. This hides renderer-specific implementation details inside the wlr_renderer interface. Non-GLES2 renderers may not use EGL. This removes all EGL dependencies from the backends.

These aren't used anymore.

2020-12-08backend/headless: add support for direct scan-outSimon Ser
I was about to add a check to fail instead of crash when the compositor uses direct scan-out, but with renderer v6 it's so simple to just add support for direct scan-out, why bother? Closes: https://github.com/swaywm/wlroots/issues/2523
2020-11-15backend/headless: implement export_dmabufSimon Ser
2020-11-15backend/headless: switch to wlr_swapchainSimon Ser
2020-11-11Remove unneeded includes from wlr_input_device.hIsaac Freund
This uncovered many places where we were using things without directly including them.
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.
2020-05-19render/egl: introduce wlr_egl_unset_currentSimon Ser
This function can be called after wlr_egl_make_current to cleanup the EGL context. This avoids having lingering EGL contexts that make things work by chance. Closes: https://github.com/swaywm/wlroots/issues/2197
2020-04-22backend/headless: add wlr_headless_backend_create_with_rendererSimon Ser
This allows one to create a headless backend with an existing renderer.
2020-04-22backend/headless: use FBOs instead of pbuffersSimon Ser
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.

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
2019-08-07Revert "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. Updates: https://github.com/swaywm/wlroots/issues/1640
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. [1]: https://patchwork.freedesktop.org/series/52324/
2019-04-23output: refactor backend APISimon Ser
This updates the backend part of the output API. This is mostly renaming: make_current becomes attach_render and swap_buffers becomes commit. This also fixes the RDP backend to support NULL damage.
2019-04-22Fix missing headers when building without X11Alyssa Ross
The deleted includes are redundant, because other headers will include the necessary files. Additionally, they cause build failures, because including EGL/egl.h or EGL/eglext.h directly, instead of through wlr/render/egl.h or wlr/render/interface.h, will mean that MESA_EGL_NO_X11_HEADERS will not have been defined, and so the EGL headers will attempt to pull in unnecessary X11 headers that may not exist on the system. For the headers produced by glgen.sh, the includes couldn't simply be deleted, because no other header would include the EGL headers. Neither wlr/render/egl.h or wlr/render/interface.h felt appropriate to include, so I opted instead to copy the MESA_EGL_NO_X11_HEADERS definition before the EGL includes.

2019-03-15backend/headless: improve output number handlingBrian Ashworth
This improves the way the output numbers are handled for the headless backend. Instead of using the number of active outputs plus one, the last used number is stored and new outputs will increment it. This fixes the situation where you start with one output, create a second, close the first, and create a third. Without this, both outputs will be HEADLESS-2, which causes an issue since the identifier will also be identical. With this, the last output is HEADLESS-3 and the outputs can be distinguished.
