Just like other backends, use the EGL GBM platform. This will make it
easier to move the allocator and renderer initialization out of the
backends.
|
|
|
|
|
|
Instead of re-importing a buffer each time we submit a new frame, re-use
the wl_buffer objects if possible.
|
|
|
|
The cursor surface still uses a wl_egl_window.

Every host seat with pointer capability propagates events to one of
sub-pointer depending which output window we entered.
active_pointer tracks reference to sub-pointer on enter/leave events to
avoid lookup for it on every move events.
Fixes swaywm/wlroots#1499

This uncovered many places where we were using things without directly
including them.
|
|
|
|
|
|
Goal currently is to get support working for a single output, thus there is only one touch device created.
Multi-output support is left for later.
|
|
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.
|
|
Previously, we just assumed submitting a new frame would make the
compositor release the current one. This isn't always the case, for
instance Sway retains old buffers when a transaction is pending. This
resulted in synchronization issues with clients writing in
front-buffers.
Fix this by un-referencing a wlr_buffer when the parent compositor sends
wl_buffer.release.
Tested by running a fullscreen mpv instance in Sway with the Wayland
backend.

We just send relative motion events alongside absolute motion events.
Compositors can figure out how absolute and relative events are related
(e.g. whether they have been triggered by the same logical event) with
the frame event.

Closes: https://github.com/swaywm/wlroots/issues/1830

|
Mostly address feedback from emersion on PR #1694
Remove const qualifier from char *name, to allow free() call
|
|
This allows wlroots based compositors to properly use graphic tablets
with the wayland backend.
This should be a decent quality of life improvement when working on
tablet related features.

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.
|
|
|
|
We bind to it but never use it.
|
|
This allows the toplevel to have proper decorations on compositors that support
xdg-decoration-unstable-v1.
|
|
This improves the way the output numbers are handled for the wayland
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
`WL-2`, which causes an issue since the identifier will also be
identical. With this, the last output is `WL-3` and the outputs can be
distinguished.

The renderer redesign is going to need the render fd before the backend
is fully started, so we have to move the wl registry code to when the
backend is created instead of when it is started.
We also need to stash the wl_keyboard and emit it to library users
later, once they've added their listeners and started the backend.
|
|
Registry was a very small file, and is heavily related to the backend,
so there is not point in keeping them separate.
|

This changes the `wlr_output_impl.set_cursor` function to take a
`wlr_texture` instead of a byte buffer. This simplifies the
DRM and Wayland backends since they were creating textures from
the byte buffer anyway.
With this commit, performance should be improved when moving the
cursor since outputs don't need to be re-rendered anymore.

This backports some changes to #319 to fix the screenshooter data
format. This also adds wlr_backend_get_renderer which will be
useful to support multiple renderers.
