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.
|
|
This ensures compositors don't forget to set the committed flag
or the mode_type when setting a field.
|
|
This refactors output_ensure_buffer() to not mutate the state passed,
making the previous subtle behavior much more explicit.
Fixes: d483dd2f ("output: add wlr_output_commit_state")
Closes: #3442

CTA-861-G says that "graphics" is used to indicate non-analog (ie,
digital) content. With that bit set, the sink should turn off analog
reconstruction and other related filtering.
|
|
This adds a configure_bounds event to let the client know of the
preferred maximum window geometry size.
|
|
This commit ensures that outputs that weren't created by the output
layout helper aren't destroyed on the output layout change.
Consider the following piece of logic:
// struct wlr_output *o1, *o2;
// struct wlr_scene *scene;
// struct wlr_output_layout *layout;
wlr_scene_attach_output_layout(scene, layout);
wlr_output_layout_add_auto(layout, o1);
struct wlr_scene_output *so2 = wlr_scene_output_create(scene, o2);
wlr_output_layout_move(layout, o1, 100, 200);
// so2 is invalid now

|
|
Compositors can just listen to wlr_output.events.destroy instead.
|
|
This will supersede wlr_output_cursor_set_image, and then later
also supersede wlr_output_cursor_set_surface.
|
|
|
|
This seems like nothing interesting was done with this. Let's simplify
and allow us some flexibility in the future.

Now that the DRM backend no longer depends on GBM, we can make it
optional. The GLES2 renderer still depends on it because of our EGL
device selection.
This is useful for compositors with their own renderers, and for
compositors using the Vulkan renderer.
|
|
Same as wlr_output_commit, but takes a wlr_output_state.
|
|
|
|
Same as wlr_output_test, but takes a wlr_output_state argument.
|
|
No functional change.
|
|
|
|
Groundwork for the following commits. The goal is to allow users
to specify their own wlr_output_state instead of wlr_output.pending.
|
|
|
|
|
|

|
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.
|
|
|
|
These are trivial wrappers around eglMakeCurrent and
eglGetCurrentContext. Compositors which need to call these
functions will also call other EGL or GL functions anyways. Let's
reduce our API surface a bit by making them private.
|
|
Compositors can use wlr_egl_create_with_context if they need a
custom EGL display or context.
|
|
This allows compositors to integrate with the wlroots GLES2
renderer, if they need to perform custom GL rendering.
|
|
This has been superseded by the standard EGL_NO_X11 switch,
supported by Mesa 19.3.0+.
|
|
Unify the way we document our APIs. See CONTRIBUTING.md for the
rules.
|
|
This information is stored in wlr_swapchain, no need to duplicate
it.
|
|
Same as [1].

This will display red translucent rectangles on the screen regions that
have been damaged. These rectangles will fade out over the span of 250
msecs. If the area is damaged again while the region is fading out,
the timer is reset.
Let's also disable direct scan out when this option is enabled, or else
we won't be able to render the highlight damage regions.
