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.
2020-05-20render/egl: unset current context after swapping buffersSimon Ser
After swapping buffers, it doesn't make sense to perform more rendering operations. Unset the context to reflect this. This commit makes it so the context is always only current between wlr_egl_make_current and wlr_egl_swap_buffers. This is an alternative to [1]. [1]: https://github.com/swaywm/wlroots/pull/2212
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
2020-04-08Add 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.

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
2019-11-19backend/x11: Revert usage of present extensionScott Anderson
This reverts commit 3317134adff0ed179e0ecaea6d778dbd0684f771. This reverts commit a3c3b928a3814f1a44babf487b1508415958c721. There are some serious issues when running this on a real X server, as opposed to running this on Xwayland, where this was tested. More investigation needs to be done into why these issues happen and if our usage of the present extension is correct.
2019-11-02backend/x11: Give X11 a real rendering loopScott Anderson
Makes use of the present extension to get notified of vsync, and not require any stupid timer hacks. Also make use of the present version of ConfigureNotify, because why not?
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.

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.

2019-03-15backend/x11: improve output number handlingBrian Ashworth
This improves the way the output numbers are handled for the x11 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 X11-2, which causes an issue since the identifier will also be identical. With this, the last output is X11-3 and the outputs can be distinguished.
2019-01-24backend/x11 & backend/wayland: make set_title NULL-safeJente Hidskes
Set the default "wlroots - " title when the title argument to the set_title functions is NULL. Otherwise, for at least the Wayland backend, we'd crash because xdg_toplevel_set_title doesn't handle a NULL pointer.

When the Xlib connection is removed, this _conn suffix is going to be pointless. I'm removing this preemtively for that.

2018-04-15x11 backend: Do not set a back pixel on windowsUli Schlachter
Before this commit, the x11 server would fill any exposed area with white before the wlroots x11 backend got a chance to do anything. This was e.g. visible when running rootston and resizing the window: When the window becomes larger, the new area is filled with black. By just not setting a back pixel value, this commit gets rid of this behaviour. Signed-off-by: Uli Schlachter <psychon@znc.in>
