Before we were populating wlr_output.current_mode with a generated
fixed mode when a custom mode was committed in the DRM backend. But
that's no longer the case: now a custom mode behaves the same under
the DRM backend and other backends.
wlr_output_layout was still assuming that an output without a
current_mode was disabled. Fix that assumption.
Fixes: 5567aefb1c ("backend/drm: Don't add pollute fixed modes list with custom modes")
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3743
Currently wlr_output holds a wl_display, but it will go away soon.
Instead of relying on that field in wlr_output_create_global(),
make the dependency explicit by taking a wl_display as argument.
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.
This requires functions without a prototype definition to be static.
This allows to detect dead code, export less symbols and put shared
functions in headers.
If box->width/height is <= 0, the box doesn't contain any points, and so
there is no closest point. wlr_box_closest_point should return NAN in this
case.
In addition, we need to handle empty boxes in a few other
output-layout-related places, because outputs can have size 0x0 when
they are created or destroyed.
If there were no outputs in the output layout,
wlr_output_layout_get_box would return the box:
{
.x = INT_MIN,
.y = INT_MIN,
.width = INT_MIN - INT_MAX,
.height = INT_MIN - INT_MAX
}
which results in an integer underflow for both the width and height.
This changes the logic to have the box be all zeroes, since an empty
output layout does not have a width or height and the location of
something without a size is irrelevant so this just uses the origin.
wlr_cursor: make sure the output doesn't have a cursor before
creating a new one
wlr_output_layout: don't emit the "add" event when the output is
already in the layout
This decouples wlr_output_enable and the wl_global.
The previously internal functions wlr_output_(destroy/create)_global are
exposed and used automatically in the wlr_output_layout to create/tear
down the global.
The compositor can handle them itself if it wants to, but I think this
is the right moment to create/destroy the wl_output when the
wlr_output_layout is used.
