This lets compositors check whether direct scan-out is possible.
Compositors will soon be responsible for manually calling this
function.
|
|
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).
|
|
The will be used by the Wayland backend to figure out whether
updating sub-surface position is necessary.

|
Amend b7e9ad79 to remove wlr_wl_input_device_get_seat definition.

- Simplifies the backends
- Avoids having two ways to do the same thing: previously one could
disable a layer by either omitting it from wlr_output_state.layers,
or by passing a NULL buffer
- We can change our mind in the future: we can allow users to omit
some layers and define a meaning without breaking the API.

Just like _WLR_FILENAME and _WLR_ATTRIB_PRINTF, this makes it more
obvious that this isn't part of our API.
|

The goal is to simplify wlr_output by moving all of its rendering
API into separate helpers. Here is a first step to sunset
wlr_output_attach_render(). Instead, compositors call
wlr_output_configure_primary_swapchain(), wlr_swapchain_acquire(),
wlr_renderer_begin_with_buffer() and wlr_output_attach_buffer().
Note that compositors can supply a base struct wlr_output_state.
This is useful to allocate a buffer suitable for submission with
a modeset, for instance.

We've had this struct for a while. It'd be useful for compositors
if they want to manage the swap chains themselves instead of being
forced to use wlr_output's. Some compositors might also want to use
a swapchain without an output.
|
|
When e.g. screencopy-v1 is active, callers are responsible for
disabling output layers.
|
|
|
|
Same as the original function, but check for the bitfield before
calling pixman_region32_fini(), because that function expects an
initialized region.
|

|
|
We don't need to pull wlr_compositor.

This is based on previous work [1] [2].
This new API allows compositors to display buffers without needing to
perform rendering operations. This API can be implemented on Wayland
using subsurfaces and on DRM using KMS planes.
Compared to [1], this approach leverages wlr_addon_set to let backends
attach their own private state to layers, removes the pending
state (necessary for interop with wlr_output_commit_state()) and
enum wlr_output_layer_state_field.

This is needed for compositors that want to reserve space for
XWayland panels. Such a feature can be useful in a "transitional"
setup, where only the X11 window manager and compositor is replaced
but other components of an X11 desktop environment are still used.
This change simply reads the X11 property; the compositor is free
to ignore it. Thus, compositors that don't want to support such a
"transitional" feature are not impacted.
v2: Update xwayland_surface_associate()
|
|
|
|
This implements the WIP wp-fractional-scale-v1 protocol.
|
|
|
|
|
|
Instead of using const pointers, use structs owned by the tranche.
This will allow wlroots to expose helpers to build feedback
objects.
|
|
This renames it to wlr_scene_surface_try_from_buffer to be more clear
that this function can return NULL. This is inline with the rest of
wlroots[1].

This new function replaces wlr_surface_is_xwayland_surface() and
wlr_xwayland_surface_from_wlr_surface().
|
|
"left_ptr" is the X11 name, "default" is the cursor spec name.
|
|
We made a similar change to wlr_xdg_toplevel.
|
|
This is more descriptive, and avoids the confusion with
wlr_xdg_surface.added.
|

Without outputs, all points are equally invalid anyway, but for e.g.
cursor warping it makes more sense to preserve the original position.
|
|
This was changed to a bitfield by mistake.

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().
|

The logic isn't correct.

- wlr_output_layout_add{,_auto}() now return a bool indicating whether
the function has succeeded.
- wlr_output_layout_move() is removed.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/1083

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.
