By using this function, a compositor can display a wlroots
compositor in a sub-surface, for instance.
|
|
When integrating wlroots with another toolkit, wlroots may receive
wl_pointer.enter events for surfaces not backed by a wlr_output.
Ignore such surfaces by tagging the ones we're aware of with
wl_proxy_set_tag().
|
|
This allows compositors to use an existing wl_display, to integrate
wlroots with an existing toolkit.

We can just use a regular assignment instead. This is more
type-safe since there is no need to provide the struct size.
The remaining memcpy() calls perform array copies or copies from
void pointers (which may be unaligned).

The PID of an X11 window cannot change.
This is a remnant from the days when we queried the PID with a
window property, instead of using XRes.

When a wlr_output add to wlr_output_layout, wlr_cursor will create
wlr_buffer of xcursor for the wlr_output, this behavior depends
wlr_renderer of wlr_output, using assert to ensure renderer is
initialized before wlr_output_layout_add and wlr_cursor_set_buffer/
wlr_cursor_set_xcursor.

|
xwm_get_atom_name() performs a roundtrip to the X11 server. Avoid
calling this blocking function if debug logs are turned off.

Downgrades the error message printed out when no DRM backend is given from `WLR_ERROR` to
`WLR_DEBUG`

glslang 12.3.0 renamed glslangValidator to glslang,
use that by default and use the old name as a fallback.

The wlr_xwayland_surface_v1 will be destroyed automatically
from xwl_surface_role_destroy().
|
|
We were only restoring fixed modes here. The DRM backend no longer
creates fixed modes when the compositor sets a custom mode, so we
need to handle this situation when restoring.

This adds the suspended toplevel state

Opaque region is a optimization hint, (bugs outstanding) it will not
change the output contents, therefore damage does not need to be submitted.
However, we still need to update the visibility state of the other
nodes in the tree. To do this call scene_update_region() by ourselves
but not `scene_node_update()` which will damage the outputs.
|
|
We need to intersect the opaque region with the node size or else we'll
get damage tracking effects with compositors attempting to use
wlr_scene_buffer_set_opaque_region() along with resizing the buffer
at the same time in a certain order.
Consider this: I have a new buffer that I want to commit to my scene buffer
that is smaller than the old one. However, I still have the old opaque
region that is the size of the old larger buffer, so that means that
for the small moment between when we reconfigure the opaque region for the
new buffer the opaque region will be oversized. Scene logic will then
try to apply occluding optimizations outside of the node boundaries
causing damage artifacts.

Add the missing lock_surface_destroy which was removed in dc7686c114f8
("session-lock: don't remove inert role resource"). Otherwise we never
remove the surface from our internal state, leading to us killing the
locking daemon with a protocol error that is totally our fault.

needs_frame is for backends to trigger frames for reasons that
compositors couldn't see coming. schedule_frame is freaky and I want to
remove it. These protocols aren't backends but in this case they're
close enough, so switch to needs_frame.

Instead of passing the scale, pass the source and destination
boxes.

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);
| ^~~~~~~~~~~~~~~~
|
|
Without a round in this case the damage region is translated to truncated coordinates, potentially
misplacing it relative to the actual position of that region in the output buffer.

wlr_client_buffer is a bad indicator for direct scan-out.
Compositors might use the underlying wlr_buffer instead.
|
|
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.
|
|
This contains the output and a bool indicating direct scan-out.
|
|
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.
|
|
We would transform the damage based on output state which might be
out of date.
|
|
|
|
With this, errors should be properly wrapped in the debug scope.
|

|
|
Let's not allow renderer implementations to mutate the passed in
options.
|
|
This slightly improves type safety.
The culprits were found with:
git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'
|
|
We can just refer to the struct field here.
