A lot of protocols extend the wl_surface state. Such protocols need
to synchronize their extended state with wl_surface.commit and
cached states. Add a new utility for this purpose.
`gcc-14` added a new `-Wcalloc-transposed-args` warning recently. It
detected minor infelicity in `calloc()` API usage in `wlroots`:
../backend/libinput/tablet_pad.c: In function 'add_pad_group_from_libinput':
../backend/libinput/tablet_pad.c:36:38: error: 'calloc' sizes specified with 'sizeof' in the earlier argument and not in the later argument [-Werror=calloc-transposed-args]
36 | group->rings = calloc(sizeof(unsigned int), group->ring_count);
| ^~~~~~~~
../backend/libinput/tablet_pad.c:36:38: note: earlier argument should specify number of elements, later size of each element
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
We have current and pending state and the code uses struct
assignments between them and resets and frees in multiple places.
Introduce a reset() function so we can unify that.
It can be useful for compositors to get the real DRM FD instead of
the one from the parent compositor. For instance, some compositors
might want to perform some DRM IOCTLs there to check the driver
name, fetch some DRM resources, etc. This will also be a requirement
for direct scanout on secondary GPUs.
ffmpeg, epoll-shim, libpng were dependencies for client examples.
These have been split into a separate repository so we no longer
need to install them.
Instead of requiring a manual soversion bump each time we do a
release, automatically compute it from the version number.
In the early days we used to not bump soversion, so there is an
hardcoded offset.
This will need to be updated once we ship 1.0, so assert that we're
still on 0.x.
wlr_cursor is responsible for sending enter/leave events, but
doesn't send fractional-scale-v1 and wl_surface.preferred_buffer_scale
events. This is not an easy thing to do from a compositor, so let's
just do it in wlr_cursor itself.
This is the last of a set of commits which ensures that both textures
and render buffers can be accessed through _UNORM and _SRGB image
views. While _UNORM image views are not yet used for 8-bpc image
formats, they will be needed in the future to support color transforms
for both textures and render buffers.
