836cb820d0 backend/drm: call get_drm_connector_props() when creating connector
This function fetches property IDs. These don't change for the
lifetime of the connector. Instead of refreshing the property IDs
on hotplug (and leaving property IDs unset for disconnected
connectors), only fetch the property IDs when we create the
connector.

d368028bd5 allocator: remove backend parameter in allocator_autocreate_with_drm_fd
Since we only use the backend capabilities here we can simply pass
them in directly. This allows other locations to create an allocator
even if they don't have a backend. They can simply specify the caps
they want instead.

f81c3d93cd backend/drm: save current refresh rate
wlr_output.refresh is populated by core wlr_output, and thus will
be zero for a custom mode with an unset refresh rate.

Save the refresh rate from the drmModeModeInfo in wlr_drm_connector
instead.

d8c0707e27 backend/drm: return secondary backend DRM FD
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.

ae3d7a697c backend/drm: use DRM_IOCTL_MODE_CLOSEFB instead of RMFB
RMFB implicitly performs a modeset to turn off any CRTC which is
using the FB. This prevents seamless transitions between two DRM
masters from working.

Use the new CLOSEFB IOCTL which doesn't turn off anything and leave
it up to the compositor to turn off outputs on shutdown if it wants
to.

63792b38e4 backend/session: take wl_event_loop instead of wl_display
wl_display holds a lot more than wlr_session needs: wlr_session
only needs to wait for a FD to become readable, but wl_display
provides full access to the Wayland client and protocol objects.

Switch to wl_event_loop to better reflect the above.

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.

4932e0d347 backend/drm: ensure plane surfaces are cleaned up on shutdown
Right now this is done "by chance" because we disable all CRTCs
on shutdown. However, we'll stop doing this. Plus, if disabling
a CRTC fails, we don't cleanup properly.

45ba35719e backend/drm: Automatic non-blocking commits
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.

2cf78f4c5b output: allow_artifacts -> allow_reconfiguration
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).

Since e5fc8cd4c7 ("output: trigger frame/present events on all

commits. Stop doing so.
