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 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.

wlr_client_buffer is a bad indicator for direct scan-out.
Compositors might use the underlying wlr_buffer instead.
|
|
This slightly improves type safety.
The culprits were found with:
git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'
|
|
This is a bit more type-safe.
|
|
This fixes an issue where the panel_orientation parameter was set but wlroots was ignoring it and
returning OUTPUT_TRANSFORM_NORMAL.

Leave it up to the compositor to enable new outputs (just like the
DRM backend does).
|
|
We have nothing to do when a headless output is enabled/disabled.
|
|
A no-op commit should not schedule a new frame. This aligns the
headless backend with the rest of the backends.
This will be important to handle the enabled → disabled transition.
|

|
Removes duplication across all the backends to finally apply the mode
to the output.
|
|
|
|
|
|
Nobody remembers why this is done and it isn't that great if people
use a lot of custom modes.
|
|
wlr_output_update_needs_frame() is called unconditionally at the
end of the function already.
|
|
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.

Destroying the liftoff_device invalidates all of the liftoff_planes.
Destroy the liftoff_planes before the liftoff_device to fix this.
|

|
This is more readable and consistent with the rest of wlroots.
|
|
If the same button is pressed on two devices on the same seat,
ignore the second event.
This is also what Mutter does.

The kernel complains when the damage exceeds the FB bounds:
[73850.448326] i915 0000:00:02.0: [drm:drm_atomic_check_only] [PLANE:31:plane 1A] invalid damage clip 0 0 2147483647 2147483647
Make the DRM backend behave like the Wayland one and allow compositors
to damage (0, 0, INT32_MAX, INT32_MAX) to repaint everything without
needing to know the exact buffer size.

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.

Use the viewporter protocol to scale output layers.
|
|
This allows compositors to get back the raw drmModeModeInfo and
look at DRM-specific fields and flags.

Commit 90d08f8f1c40e2a302d62052435ff2abdb08a854 changed the way
wlr_drm_format_intersect worked, including passing in a destination
format list. This breaks scenarios where the intersection doesn't
find any matching formats, since we still have a valid destination
format set. This changes it to only return true if more than one
matching format is present in the intersection list.
|
|
In the logic of the DRM backend in backend_destroy, wlr_backend_finish
is called first, then the outputs are destroyed and then the
display->destroy.link is removed from the list.
This commit applies the same order to the headless backend.
|
|
|
|
Now it takes a reference to a destination format
|
|
|
|
|
|
|
|
Add a src_box state field. Use the SRC_* KMS props in the DRM
backend, reject the layers in the Wayland backend (for now, we can
support it later via viewporter).
|
|
This allows callers to set a destination size different from the
buffer size to scale them.
The DRM backend supports this. The Wayland backend doesn't yet
(we'd need to wire up viewporter).
|
|
|
|
|
|
|
|
since wayland doesn't provide a touch id in cancel events, track what
points are active so we can cancel all of them
timestamp is also not provided - use 0 because no one's paying attention
to that anyway
Closes #3000

Helps figuring out why e.g. get_primary_formats fails.
