Simon Ser 260dbdf704 backend/drm: split wlr_drm_fb related functions into separate file 2023-11-30 14:44:46 +00:00
Simon Ser 8c44e86077 backend/drm: add wlr_drm_connector_state.nonblock 
Instead of having this condition checked in multiple places,
centralize it so that they don't go out-of-sync.

Simon Ser 3b53d1cbf1 backend/drm: introduce page-flip tracking struct 
Introduce a per-page-flip tracking struct passed to the kernel
when we request a page-flip event for an atomic commit. The kernel
will pass us back this pointer when delivering the event.

This eliminates any risk of mixing up events together. In particular,
if two events are pending, or if the CRTC of a connector is swapped,
we no longer blow up in the page-flip event handler.

Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3753

Simon Ser fffa1908af backend/drm: fix libliftoff_plane double-free 
Destroying the liftoff_device invalidates all of the liftoff_planes.
Destroy the liftoff_planes before the liftoff_device to fix this.

Simon Ser 4339c37f99 backend/drm: clip FB damage 
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.

Simon Ser 44069dfd5e output-layer: add cropping support 
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).

Simon Ser 835208db98 output-layer: add support for scaling buffers 
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).

Simon Ser 8338d17d7e backend/drm: drop wlr_drm_layer.pending_{width,height} 
No need to store this info in struct wlr_drm_layer. We can just
extract the size when we need it.

Simon Ser bbd5145d8a backend/drm: drop unnecessary pixman_region32_t casts 
The Pixman API now accepts const parameters.

Simon Ser 2398621b8b backend/drm: add libliftoff composition layer 
This will be useful for implementing the output layers API.
