Some formats like sub-sampled YCbCr use a block of bytes to
store the color values for more than one pixel. Update our format
table to be able to handle such formats.
|
|
|
|
This is implemented by a two-subpass rendering scheme; the first
subpass draws (and blends) onto a linear R16G16B16A16_SFLOAT buffer,
while the second subpass performs linear->srgb conversion, writing
onto the actual output buffer.
|
|
|
|
Now it takes a reference to a destination format
|

Don't store modifiers as part of the struct.
|
|
This is implied by the fact that this function finishes the state instead
of destroying it.
|
|
|
|
We were storing a wlr_output without listening for the destroy
event.

The usages in linux_dmabuf zero out the dst before passing it so this
change should be fine.
|
|
|
|
|
|
This would break if you are running with a NULL renderer.
|
|
This is supposed to be an unstable interface and it was a mistake that
this header was not included.
|
|
|
|
Allow callers to pick the blend mode when rendering a rect. The
"none" mode can be used to disable blending and clear rects.
|
|
This simplifies the vkQueueSubmit call, removing the need to pass
timeline semaphore point values as separate arrays.
|
|
|
|
This logic is used twice.
|
|
Same as wlr_output_render_software_cursors(), but takes a
struct wlr_render_pass.
|
|
Add a render pass implementation which leverages the legacy
rendering API. This is helpful during the migration.
|
|
|
|
Goals:
- Extensibility: we need to be able to add new params to the calls
to render a texture/rect. For instance we'll need to add fences to
the render texture operation for explicit sync purposes.
- No implicit state: no more bind_buffer, begin, end.
- No matrices: these hurt Pixman and we don't need them.
- Clip regions for optimized damage repainting.

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 makes grepping much easier.
|
|
xcursor.c was copied over from libwayland-cursor. A lot of
cosmetic imporvements have been merged upstream. Copy-paste the
new version.

This allows wlroots to support newer versions of the interface
without breaking the API.
|

|
|
Compositors can migrate to wlr_damage_ring.
|
|
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.
|
|
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

Amend b7e9ad79 to remove wlr_wl_input_device_get_seat definition.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3611

- 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.
