We currently only perform non-blocking commits for non-modeset commits
with a buffer attached.
Perform non-blocking commits whenever there is no pending pageflip
event. If a non-blocking modeset commit fails, which can happen if the
driver implicitly added more CRTCs to the commit that we did not know we
had to wait for, retry with a blocking commit.

The name "allow_artifacts" and associated description is very vague, and
theoretically allow for tearing behavior. Clarify that we only intend to
mean artifacts related to output configuration (e.g., modesets).

DRM_MODE_PAGE_FLIP_ASYNC doesn't allow user-space to submit new
buffers before waiting for the uevent: the kernel will return EBUSY
in that case.
Fixes: c2aa7fd965 ("backend/drm: Add async page flip support to legacy")
Since e5fc8cd4c7 ("output: trigger frame/present events on all
commits on enabled output"), any commit on an enabled output is
supposed to trigger frame/present events.
The DRM backend was skipping the commit completely for no-op
commits. Stop doing so.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3719
Up until now, frame/present events were only triggered when the
user submitted a buffer. Change the wlr_output API so that these
events are triggered when any commit is applied on an enabled
output.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3708
We were only restoring fixed modes here. The DRM backend no longer
creates fixed modes when the compositor sets a custom mode, so we
need to handle this situation when restoring.

This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.
A new wlr_output_state_init() function takes care of initializing
the Pixman region.
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.
Closes: https://github.com/swaywm/sway/issues/7632
Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory
The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.
Commit 90d08f8f1c changed the way
wlr_drm_format_intersect worked, including passing in a destination
format list. This breaks scenarios where the intersection doesn't
find any matching formats, since we still have a valid destination
format set. This changes it to only return true if more than one
matching format is present in the intersection list.
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 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).
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.
The hardcoded fallback "/usr/share/hwdata/pnp.ids" was only a
temporary solution to get things working while distributions were
still working on shipping it.
