Scott Anderson 51a283cbe4 backend/x11: Rename xcb_conn to xcb
When the Xlib connection is removed, this _conn suffix is going to be
pointless. I'm removing this preemtively for that.

Use #if instead of #ifdef for wlroots config data
This prevents some annoying issues when e.g. not including wlr/config.h or
making a typo in the guard name.

backend/wayland: handle WL_EVENT_WRITABLE for Wayland socket
We need to flush when the connection is writable again. This is important in
case the write buffer becomes full. This is also what Weston does [1].

Scott Anderson bbce92a923 backend/wayland: Move initilisation code earlier
The renderer redesign is going to need the render fd before the backend
is fully started, so we have to move the wl registry code to when the
backend is created instead of when it is started.

We also need to stash the wl_keyboard and emit it to library users
later, once they've added their listeners and started the backend.

Scott Anderson 4e03802057 backend/wayland: Move registry into backend
Registry was a very small file, and is heavily related to the backend,
so there is not point in keeping them separate.

backend/drm: specify minimum config attributes
Since the format used by DRM is GBM_FORMAT_ARGB8888, we need at least a R, G, B
and A channel.

backend/drm: fix frame scheduling on secondary GPUs

backend/drm: fix frame scheduling on secondary GPUs
There was a missing copy_drm_surface_mgpu call in drm_connector_schedule_frame
so we asked for a pageflip with an unknown BO, resulting in ENOENT.

Additionally, this commit makes schedule_frame return a bool indicating
failures. This allows schedule_frame_handle_idle_timer to only set
frame_pending to true if a frame has been successfully scheduled. Thus, if a
pageflip fails, rendering won't be blocked forever anymore.

In case a pageflip is already pending, true is returned because a frame has
already been scheduled and will be sent sometime soon.

backend/drm: add WLR_DRM_NO_ATOMIC_GAMMA env variable
This allows the legacy interface to be used instead of atomic if needed. This
is a workaround to make some Intel GPUs work (if this variable is unset) as
well as to make some AMD GPUs work (if this variable is set).

emersion b66041a9e5 backend/drm: don't reset conn->pageflip_pending in drm_connector_cleanup
If a pageflip is pending before cleanup, it's still pending after. This
is used line 1177: drm_connector_cleanup is called and
conn->pageflip_pending is checked afterwards.

emersion 46b1ba386f output: remove idle_frame event source when destroying output
This prevents the idle event to be activated on a destroyed
output.

This also makes the backend responsible for free-ing modes, as it
is the one allocating them and adding them to the list. Note that
the DRM backend (the only one using modes) already frees them.

emersion ba91422747 output: don't trigger a frame immediately in schedule_frame
This desynchronizes our rendering loop with the vblank cycle.

In case a compositor doesn't swap buffers but schedules a frame,
emitting a frame event immediately enters a busy-loop.

Instead, ask the backend to send a frame when appropriate. On
Wayland we can just register a frame callback on our surface. On
DRM we can do a no-op pageflip.

emersion 79dd9ba151 backend/drm: don't free connector immediately
When a pageflip is pending, we'll get a DRM event for the connector
in the future. We don't want to free the connector immediately
otherwise we'll use-after-free in the pageflip handler.

This commit adds a new state, "DISAPPEARED". This asks the pageflip
handler to destroy the output after it's done pageflipping.

nyorain 7b52388424 Rework session handling
Sessions can now be retrieved from a backend in a more general manner.
Multi-backend gets back its `session` field that contains the session
if one was created, removing the interfacing from multi backend with the
drm backend directly. This adds the possibility to use sessions even
without the drm backend.

It additionally fixes the bug that 2 session objects got created when
WLR_BACKENDS were set to "libinput,drm".

To allow vt switching without drm backend (and drm fd) on logind, start
listening to PropertiesChanged signals from dbus and parse the session
"Active" property when no master fd was created (this does not change
current drm backend behaviour in any way).

emersion f8a50e4fe7 backend/drm: steal CRTCs from disabled outputs
This commit allows outputs that need a CRTC to steal it from
user-disabled outputs. Note that in the case there are enough
CRTCs, disabled outputs don't loose it (so there's no modeset
and plane initialization needed after DPMS). CRTC allocation
still prefers to keep the old configuration, even if that means
allocating an extra CRTC to a disabled output.

CRTC reallocation now happen when enabling/disabling an output as
well as when trying to modeset. When enabling an output without a
CRTC, we realloc to try to steal a CRTC from a disabled output
(that doesn't really need the CRTC). When disabling an output, we
try to give our CRTC to an output that needs one. Modesetting is
similar to enabling.

A new DRM connector field has been added: `desired_enabled`.
Outputs without CRTCs get automatically disabled. This field keeps
track of the state desired by the user, allowing to automatically
re-enable outputs when a CRTC becomes free.

This required some changes to the allocation algorithm. Previously,
the algorithm tried to keep the previous configuration even if a
new configuration with a better score was possible (it only changed
configuration when the old one didn't work anymore). This is now
changed and the old configuration (still preferred) is only
retained without considering new possibilities when it's perfect
(all outputs have CRTCs).

User-disabled outputs now have `possible_crtcs` set to 0, meaning
they can only retain a previous CRTC (not acquire a new one). The
allocation algorithm has been updated to do not bump the score
when assigning a CRTC to a disabled output.
