Stop assuming that the state to be applied is in output->pending in
crtc_commit. This will allow us to remove ephemeral fields in
wlr_drm_crtc, which are used scratch fields to stash temporary
per-commit data.
On multi-GPU setups, there is a primary DRM backend and secondary
DRM backends. wlr_backend_get_drm_fd will always return the parent
DRM FD even on secondary backends, so that users always use the
primary device for rendering.
However, for our internal rendering we want to use the secondary
device. Use allocator_autocreate_with_drm_fd to make sure the
allocator will create buffers on the secondary device.
We do something similar to ensure our internal rendering will
happen on the secondary device with renderer_autocreate_with_drm_fd.
Fixes: cc1b66364c ("backend: use wlr_allocator_autocreate")
This function is only required because the DRM backend still needs
to perform multi-GPU magic under-the-hood. Remove the wlr_ prefix
to make it clear it's not a candidate for being made public.
This reverts commit f9f90b4173.
gbm_bo_get_modifier may return a modifier in these cases:
- The kernel doesn't support modifiers but Mesa does
- WLR_DRM_NO_MODIFIERS=1 is set
However, in both of these cases, the gbm_bo has been allocated
without modifiers.
There is already a check in drm_fb_create for modifiers:
wlr_drm_format_set_has will make sure buffers with an explicit
modifier will be rejected if the DRM backend doesn't support them.
So no need for an additional check in get_fb_for_bo.
Closes: https://github.com/swaywm/wlroots/issues/2896
The previous code would always print "falling back to legacy method",
even if the format wasn't ARGB8888.
Drop get_fb_for_bo_legacy, since the code can just be inlined without
hurting readability.
Ideally we should only fallback to drmModeAddFB if the error code
indicates the BE failure, but the original PR [1] doesn't say what
error code is returned by the kernel.

We shouldn't strip a modifiers from buffers, because the will make
the kernel re-interpret the data as LINEAR on most drivers,
resulting in an incorrect output on screen.
Stop listing all available cursors each time a cursor theme is
loaded. They can be obtained from the CLI instead, e.g.
ls /usr/share/icons/Adwaita/cursors
Prior to this commit, WLR_RENDERER was only looked up when the
backend returned a DRM FD.
Make it so WLR_RENDERER is always looked up, so that running wlroots
on a system without a GPU and with WLR_RENDERER=gles2 fails as
expected instead of falling back to the Pixman renderer.
Switch from the pkg-config dependency names to the upstream
libxcb repository names. Each repository contains multiple
libraries but is generally available in distributions as a single
package.
libxcb contains xcb, xcb-composite, xcb-xfixes, xcb-xinput and
xcb-shm. libxcb-render-util contains xcb-render. libxcb-wm
contains xcb-icccm. xcb-image was outdated and is no longer needed.
`_NET_WM_PID` is unreliable: it is optional and even if set it may
contain PIDs from sandbox namespaces or remote systems.
Prefer XRes v1.2 QueryClientIds method which returns PIDs as seen by the
Xwayland server.
Make it clear GLES2 is being used. Before this commit, various
GL-related information was printed, but not an easy-to-find line
about which renderer is being picked up.
This env var forces the creation of a specific renderer. If no renderer
is specified, the function will try to create all of the renderers one
by one until one is created successfuly.
Previously, the same struct was used for linux-dmabuf-v1 params
and buffer. This made the whole logic a little bit awkward, because
a wlr_dmabuf_v1_buffer could either be still being constructed, or
be a complete buffer.
Introduce a separate wlr_linux_buffer_params_v1 struct for buffer
params still being constructed. Once the params are complete (ie.
once the create request is sent), the params struct is destroyed
and the buffer struct is created.
This will help with [1] as well.

Drop wlr_dmabuf_v1_buffer_from_params_resource and
wlr_linux_dmabuf_v1_from_resource. Contrary to wl_buffer, these
resources are internal linux-dmabuf-v1 implementation details and
should not be shared with other interfaces.
