The back buffer is no longer set at commit time since 0556aa0c5918
("output: rejigger attach/clear for back buffer").
Instead, check whether the buffer belongs to the output swapchain.
This is more robust.

See the spec at [1]. tl;dr EGL has terrible defaults: eglTerminate()
may have side-effects on completely unrelated EGLDisplay objects.
This extension allows us to opt-in to get the sane behavior:
eglTerminate() only free's our own EGLDisplay without affecting
others.

Be consistent with other headers.
|
|
wlr_buffer.c is difficult to read because it contains a mixed bag
of unrelated things: base buffer type, buffer implementations,
buffer resource factory, and client buffer.
Split each of these into their own file.

Same as the previous commit.

dac040f87fee1cfdd7660aa1786b0734d95e03a4 mistakenly renamed
xdg_surface_destroy listener, which was listening to *unmap* events, to
xdg_surface_unmap. The actual fix, however, is to listen to destroy
events. This fixes various crashes.

We don't need to store the list of enabled extensions.
While at it, rename variables to be less confusing.
|
|
These are unused.
|
|
It returns a bool, not an int.
|
|
This was previously used by the X11 backend but is no longer required
since the previous commit.
|
|
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.

This simplifies some of the growth logic, but uses array_realloc to shrink the
array if needed.
|
|
array_realloc will grow the array for the target size like wl_insert_add, but
will also shrink the array if the target size is sufficiently smaller than the
current allocation.

Also make the regular rendering logic use the introduced
render list.
|
|
|
|
This indicates whether the surface offset has changed.
|
|
This lets the renderer handle the wlr_buffer directly, just like it
does in texture_from_buffer. This also allows the renderer to batch
the rectangle updates, and update more than the damage region if
desirable (e.g. too many rects), so can be more efficient.
|
|
We were firing the new_input signal on backend initialization,
before the compositor had the chance to add a listener for it.
Mimick what's done for wl_keyboard: if the backend hasn't been
started, delay wl_touch initialization.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3473

We can just use libdrm's drmModeConnection enum instead.
|
|
- Add wlr_output.enabled checks to CONNECTED checks
- Replace NEEDS_MODESET with CONNECTED

This implements the single-pixel-buffer-v1 protocol [1], to allow clients
to create 1x1 buffers with a single color.

This version adds a wm_capabilities event.
|

No need to manually maintain this table now.
The wlroots names and the libdrm (= kernel) names all match.

When the client doesn't support high-resolution scroll, accumulate
deltas until we can notify a discrete event.
Some mice have a free spinning wheel, making possible to lock the wheel
when the accumulator value is not 0. To avoid synchronization issues
between the mouse wheel and the accumulators, store the last delta and
when the scroll direction changes, reset the accumulator.
|
|
On newer versions of libinput, the event LIBINPUT_EVENT_POINTER_AXIS
has been deprecated in favour of LIBINPUT_EVENT_POINTER_SCROLL_WHEEL,
LIBINPUT_EVENT_POINTER_SCROLL_FINGER and
LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS.
Where new events are provided by the backend, ignore
LIBINPUT_EVENT_POINTER_AXIS, receive high-resolution scroll events from
libinput and emit the appropiate wlr_pointer signal.
|
|
Currently, the "wlr_event_pointer_axis" event stores low-resolution
values in its "delta_discrete" field. Low-resolution values are always
multiples of one, i.e., 1 for one wheel detent, 2 for two wheel
detents, etc.
In order to simplify internal handling of events, always transform in
the backend from the low-resolution value into the high-resolution
value.
The transformation is performed by multiplying by 120. The 120 magic
number is used by the kernel and it is exposed to clients in the
"WLR_POINTER_AXIS_DISCRETE_STEP" constant.
|
|
The logic doesn't support handling multiple outputs so let's not break
the assumption and handle damages per output much like how damage_ring
is done.
|
|
wlr_xdg_surface_from_wlr_surface() for example may return NULL even if
the surface has the xdg surface role if the corresponding xdg surface
has been destroyed.
|
|
This is necessary to handle damage coming from the backend and software
cursors.
|
|
|
|
wlr_damage_ring is effectively wlr_output_damage untied from wlr_output.
|
|
Events used by our input devices were recently renamed from wlr_event_* to
wlr_*_event, but the documentation and a single point of use was not updated
accordingly.
Regressed by: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3484
|
|
This union is unnecessary since the recent input device refactor and can
now be replaced by wlr_*_from_input_device() functions.

"max bpc" is a maximum value, the driver is free to choose a
smaller value depending on the bandwidth available.
Some faulty monitors misbehave with higher bpc values. We'll add
a workaround if users get hit by these in practice.

This function applies a configuration sent by a client on a
struct wlr_output_state.
|
|
Whether a texture is opaque or not doesn't depend on the renderer
at all, it just depends on the source buffer. Instead of forcing
all renderers to implement wlr_texture_impl.is_opaque, let's move
this in common code and use the wlr_buffer format to know whether
a texture will be opaque.

|
69477051ccff ("matrix: deprecate wlr_matrix_projection") marked it
as deprecated. 1 year later, we can now remove it from our public
API.
