Fixes an error seen in labwc CI builds with -Werror:
../subprojects/wlroots/include/wlr/types/wlr_gamma_control_v1.h:44:16:
error: ‘struct wlr_output_state’ declared inside parameter list
will not be visible outside of this definition or declaration [-Werror]
44 | struct wlr_output_state *output_state);
| ^~~~~~~~~~~~~~~~
The backend is not able to tell whether a surface is being
presented via direct scan-out or not. The backend will set
ZERO_COPY if the buffer submitted via the output commit was
presented in a zero-copy fashion, but will no know whether the
buffer comes from the compositor or the client.
Using "present" is confusing here: the event is emitted when the
buffer is being sampled to be displayed on an output, not when it's
being presented on-screen.
Rename to match the presentation-time terminology.
This function takes a pointer to memory with a hardcoded format
and many parameters to describe the pixel buffer.
wlr_output_cursor_set_buffer() can be used instead.
A saner replacement for wlr_cursor_set_image():
- Takes a wlr_buffer instead of numerous parameters and a hardcoded
format.
- The scale is not used to filter outputs.
- A ref to the buffer is kept to apply it to new outputs.
This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.
A new wlr_output_state_init() function takes care of initializing
the Pixman region.
This increases type safety, makes it more obvious that role_data
must represent the role object, and will allow for automatic
cleanup when the resource is destroyed.
This commit allows to make a role as not represented by an object,
which fixes calling role commit handlers for roles like cursor
surfaces.
Fixes: 099b9de752
Currently, an icon surface's role_data is set manually to a struct
wlr_drag_icon, which is hacky, incorrect (as role_data is supposed
to be the surface's role object, and drag icons don't have them), and
will be disallowed by future changes.
Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory
The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.
Many issues here:
- wlr_output_cursor_set_buffer() takes a buffer already scaled for
the output, not a buffer with scale=1.
- wlr_output_cursor.{width,height,hotspot_x,hotspot_y} are in output
buffer coordinates.
- render_cursor_buffer() had hardcoded no-ops for scale and
transform, instead of using the cursor surface's.
Fixes: b64e7e88bf ("output: add output_cursor_set_texture()")
We'll soon introduce a unified wlr_surface map event. Up until now, compositors
have been using wlr_xwayland_surface's map event to setup various wlr_surface
related listeners (e.g. commit). This will no longer be possible when that
event is moved over to wlr_surface. Introduce new events where the compositor
can add/remove wlr_surface event listeners.
This is to allow for compositors that want to be more implicit about
how their scene is organized. Such a compositor may want to walk up
at a certain scene node to find something such as a surface to focus on.
Goals:
- Extensibility: we need to be able to add new params to the calls
to render a texture/rect. For instance we'll need to add fences to
the render texture operation for explicit sync purposes.
- No implicit state: no more bind_buffer, begin, end.
- No matrices: these hurt Pixman and we don't need them.
- Clip regions for optimized damage repainting.
