This function needs to reset the structures to NULL, otherwise it is not
possible to re-use a once "freed" property info array.
Being able to re-use an array is useful when the memory allocation and
array lifetimes do not match. A specific example is drm_output that is
changed to allocate the CRTC on enable() and deallocate it on disable().
A drm_output might be enabled and disabled multiple times.

In the future when a list of drm_heads supersedes unused_connectors

Setting state_invalid to true is moved together with the code adding new
unused CRTCs and connectors in drm_output_deinit(). Logically these two
operations belong together: state_invalid is required for the new unused
item to be turned off.
This does not hinder initial turning off of outputs, because on
compositor start-up, state_invalid is initialized to true, making calls
to drm_output_disable() for non-enabled outputs a no-op.
Previous changes already ensure that if a compositor does not explicitly
enable an output, the CRTC and connector will be turned off even without
an explicit disable (provided there is a at least one enabled output).

Rather than smashing the state to disable a CRTC immediately, just
delegate that to the normal repaint cycle by setting state_invalid =
true. drm_pending_state_apply() will pick up the unused_crtcs.
A caveat here is that we have no enabled outputs at all, we will never
enter repaint, and so CRTCs do not actually get turned off until we get
at least one output to drive.
However, this should help the problem reported here:
https://lists.freedesktop.org/archives/wayland-devel/2018-January/036713.html
Arguably it is better to leave an output spuriously on in rare cases
rather than fail modeset completely in somewhat more common cases.
My personal motivation for this change is that it helps if we later move
CRTC allocation to output enable/deinit instead of create/destroy,
because then the CRTC will not be available here for initial turn-off as
the output has not been enabled to begin with.

Split repaint into two stages, as implied by the grouped-repaint
interface: drm_output_repaint generates the repaint state only, and
drm_repaint_flush applies it.
This also moves DPMS into output state. Previously, the usual way to
DPMS off was that repaint would be called and apply its state, followed
by set_dpms being called afterwards to push the DPMS state separately.
As this happens before the repaint_flush hook, with no change to DPMS we
would set DPMS off, then immediately re-enable the output by posting the
repaint. Not ideal.
Moving DPMS application at the same time complicates this patch, but I
couldn't find a way to split it; if we keep set_dpms before begin_flush
then we break DPMS off, or if we try to move DPMS to output state before
using the repaint flush, we get stuck as the repaint hook generates an
asynchronous state update, followed immediately by set_dpms generating a
synchronous state update.
In drm_output_update_complete, the *_pending flags are cleared
before any of the pending actions are taken; this ensures that the
actions cannot recurse.

If we have an unused CRTC or connector, explicitly disable it during the
end of the repaint cycle, or when we get VT-switched back in.
This commit moves state_invalid from an output property to a backend
property, as the unused CRTCs or connectors are likely not tracked by
drm_outputs. This matches the mechanics of later commits, where we move
to a global repaint-flush hook, applying the state for all outputs in
one go.
The output state_invalid flag originally provoked full changes on output
creation (via setting the flag at output enable time) and session enter.
For the new-output case, we will not have any FB in output->state_cur,
so we still take the same path in repaint as if state_invalid were set.
At session enter, we preserve the existing behaviour: as
start_repaint_loop will fail when state_invalid is set, all outputs will
be scheduled for repaint together, and state_invalid will not be cleared
until after all outputs have been repainted, inside repaint_flush.

GStreamer's waylandsink - the only user of wl_shm YUV formats - expects
the implementation to follow the example of Xv and implicitly divide the

This patch fixes the appearance of multiple windows in the parent
compositor. Previously, all windows except the one with nested output
position 0,0 would have their damage for the parent wl_surface always
fall outside of the wl_surface, save the decorations which were handled
separately. If the parent compositor was Weston/GL, this would lead to
the output area remaining black as partial GL texture uploads would
practically never update the texture. If the parent compositor was
Weston/pixman, the parent windows would not update on screen unless
something else caused the area to be repainted.

The wayland-backend with --sprawl is one way to trigger
wayland_output_create_for_parent_output(), which intends to find a mode
from the parent mode list and use it. Calling wayland_output_set_size()
initialized an embedded struct weston_mode and inserts that into the
mode list. Then the assignment output->mode = *mode; corrupts the
mode_list by overwriting the link entry. This leads to an endless loop
in bind_output() in compositor.c.
Fix this by manually doing the setup that wayland_output_set_size() did
and do not call it.
As a side effect, it now relays the parent compositor's physical output
size to our own clients. It no longer smashes the refresh rate either.

Calling wl_display_roundtrip() from within a Wayland event handler means
we will re-enter event dispatch, that is, it will lead to recursive
dispatch. Even if libwayland-client was safe, this would lead to
unexpected code paths: the first event handler function has not returned
when other event handler functions may get called. In this particular
case it maybe didn't hurt, but it's still a fragile pattern to use.
Replace the wl_display_roundtrip() with a manual sync callback to do the
work.
This does not break the wayland-backend initialization sequence, because
sprawl_across_outputs was set only after the roundtrip to ensure
wl_registry globals have been received so the code would not have been
hit anyway, and weston_backend_init() also has a second roundtrip that
ensures the per wl_output events have been received before continuing.
For wayland-backend output hotplug the change is insignificant because
it will only delay the output creation a bit, and the parent outputs are
not processed anywhere in between.

were set in weston_drm_output_api::set_mode vfunc later. This made the

The purpose of the "unknown" assignments is to give fallback values in
case EDID is not providing them.
Fix all that by moving all setting of the make, model and serial into
create_output_for_connector(). These values cannot change afterwards
anyway. While at it, document find_and_parse_output_edid().

We rely on the set_size() functions to be called only once, as is

compositor-wayland.c is strange in
wayland_output_create_for_parent_output(): it first called
wayland_output_set_size() that initialized the mode list with a single
mode manufactured from width and height and set that mode as current.
Then it continued to reset the mode list and adding the list of modes
from the parent output, leaving the current mode left to point to a mode
struct that is no longer in the mode list and with a broken 'link'

The asynchronous timepoint submissions are stored in a list in

that remain at output destruction time are cleaned up.
If timelining is inactive or the required EGL extensions are not

Note that the GPU timestamps returned by sync files are in the

This moves the single sprite creation code from create_sprites() into a
new function. The readability clean-up is small, but my intention is to
write an alternate version of create_sprites(), and sharing the single
sprite creation code is useful.
The removal code now actually removes the plane from the list.
In doing this, the gymnastics required to exact the CRTC ID the plane
was last on when making a disabling drmModeSetPlane call have been
removed; specifying the CRTC is not necessary when disabling a plane.
(The atomic API goes a step further, mandating it be zero.)

Fixes the failure to start with fbdev-backend:
weston: /home/pq/git/weston/libweston/compositor.c:4733: weston_compositor_add_pending_output: Assertion `output->disable' failed.
The disable hook was completely unimplemented, and the regression was
caused by e952a01c3b
"libweston: move asserts to add_pending_output()".
It used to work because Weston never tried to explicitly disable the
fbdev output, but now it is hitting the assert.
Fix it by tentatively implementing a disable hook. It has not been
tested to work for explicit disabling, but it does solve the regression.

It's a little awkward to try to keep the weston_output::region and
weston_output::previous_damage allocate exactly only when the output is

fini in between.
Fix both issues by allocating the regions in weston_output_init(),
always fini/init'ing them in weston_output_init_geometry(), and fini'ing

It was ambiguous what this flag meant - it did not mean whether the
backend is considering this output to be enabled, because
weston_output_destroy() unsets it while deliberately not calling the
backend disable() vfunc.
Perhaps the most clear definition is with respect to the output's
assignment in the pending vs. enabled output lists. There is also a whole
bunch of variables that are allocated only when enabled is true.
Since the flag is related to the list membership, set and clear the flag
only when manipulating the lists.

weston_compositor_add_output() and weston_compositor_remove_output()
handle the moves between the lists.
This way weston_output_enable() does not need to remove and

manually re-add the output back to the pending list.
To make everything nicely symmetric and fix any unbalancing caused by
this:
- weston_output_destroy() explicitly wl_list_remove()s
- weston_compositor_add_pending_output() first removes then inserts, as

At the bottom of weston_output_finish_frame(), code exists to account
for flips which have missed the repaint window, by shifting them to lock
on to the next repaint window rather than repainting immediately.
This code only accounted for flips which missed their target by one
repaint window. If they miss by multiples of the repaint window, adjust
them until the next repaint timestamp is in the future. This will only
happen in fairly extreme situations, such as Weston being scheduled out
for a punitively long period of time. Nevertheless, try to help recovery

commit a7cba1d4cd changed the way
the cursor plane is setup. Previously it was pre-emptively set
disabled for the next frame, and that would be changed at next
frame time if the cursor plane was to be used. It was changed
to be disabled at plane assignment time.
We disable the use of planes entirely by setting disable_planes to
a non-zero value, which bypasses all calls to assign_planes - so
if the plane was set-up in the previous frame it will retain its
state post-disable.
This leads to desktop zoom leaving the cursor plane in place when
it sets disable_planes.
This patch clears any stale cursor plane state from the redraw
handler if disable_planes is set so drm_output_set_cursor()
will do the right thing.

We make the differentiation where planes are an abstract framebuffer
with a position within a CRTC/output, and sprites are special cases of
planes that are neither the primary (base/framebuffer) nor cursor plane.
drm_sprite, OTOH, contains nothing that's actually specific to sprites,
and we end up duplicating a lot of code to deal with them, especially
when we come to use an entirely plane-based interface with atomic
modesetting.
Rename drm_sprite to drm_plane, to reflect that it's actually generic.

page_flip_pending is only be set when do a pageflip to a newly-rendered
buffer; if the flag is not set, we have landed in the start_repaint_loop
path where the vblank query fails, and thus we must pageflip to the same
buffer.
This test was not sufficient for what it was supposed to guard:
releasing framebuffers back. When using client-supplied framebuffers, it
is possible to reuse the same buffer multiple times, and we would send a
framebuffer-release event too early.
However, since we have a properly reference-counted drm_fb now, we can
just drop this test, and rely on the reference counting to prevent
too-early release of client framebuffers.
page_flip_pending now becomes exactly what the name suggests: a flag
which indicates whether or not we are expecting a pageflip event. Add
asserts here to verify that we never receive a pageflip event we weren't
expecting.
