The invalid_destroy and invalid_unlock protocol errors aren't currently
sent by wlroots and instead left up to the compositor. However, we can
handle these as well without much additional complexity.
This also adds a missing wl_resource_destroy() call if the lock is inert
in lock_handle_unlock_and_destroy().
wlroots uses "// private state" comments to denote structure fields
which shouldn't be accessed by compositors, so let's drop
wlr_output_layout_output_state and inline its fields into
wlr_output_layout_output; this also simplifies layout output creation.
With the Vulkan renderer we don't support implicit modifiers.
However wl_drm only supports implicit modifiers.
Stop advertising wl_drm formats when implicit modifiers are
unsupported.
Query the formats at init time, then forget about the renderer.
This will allow wl_drm to be created with a list of formats instead
of a renderer, and will behave better after a GPU reset.
The backend no longer changes the output state behind the
compositor's back. Instead, compositors can listen to the "commit"
event and check for WLR_OUTPUT_STATE_ENABLED/WLR_OUTPUT_STATE_MODE.

Some compositors may want to use the linux-dmabuf-v1 implementation
with a completely custom renderer. Add a function to create the
global with a default feedback.
...when only one edge is anchored.
The layer-shell protocol specifies that a positive exclusive-zone value is
'meaningful' if the surface is anchored to either:
1. one edge
2. one edge and both perpendicular edges.
For example, if you wish to position a layer-shell client along the top
edge and make it exclusive, you should be able to either set anchor=TOP or
anchor=TOP|LEFT|RIGHT. It appears that many panels/bars use the latter
approach (anchor to an edge and also both perpendicular edges) which is
probably why this has not been reported previously.
This patch adds support for the first case and thereby makes exclusive
zone behaviour consistent with the protocol and also with sway's extant
layer-shell implementation.
Now, it is checked whether an output pixel corresponds to an integer
number of buffer pixels; if it doesn't, the region is altered to take
this into account.
This allows the backend to have access to the frame damage, as
reported by the scanned-out client. Some KMS drivers can make use
of it (e.g. for PSR, or optimized USB transfers in the GUD driver),
and the Wayland/X11 backends forward it to the parent compositor.
This is a first step towards moving texture uploading out of
wlr_compositor.
This commit allows compositors to opt-out of the texture uploading
by passing a NULL wlr_renderer. An immediate user of this is
gamescope, which currently implements a stub wlr_renderer just to
make wlr_compositor happy.
