Commit 0e4f097d broke opaque regions, and since then weston will waste
time rendering occluded areas.
I think this is because we're taking the intersection of the opaque
and scissor regions even when the scissor region isn't enabled.
An easy test is to turn on triangle fan debugging with the gl renderer,
then run weston-simple-damage and move another opaque application such as
weston-terminal over it.

zero whether the config option is present or not, and it is non-zero in case
the config option is not present.
The code must check whether the config option is either true or false,

Since commit 992ee045f1 we create a new surface when we update the cursor
image. This broke animated cursors by discarding any existing frame
callback used for timing, and moving the setup for frame callbacks to
after the commit on the pointer surface.
To fix this we need another surface commit for the frame callbacks, but
this alone is not enough to fix the regression, as a lingering kludge
intended to fix problems when reusing the pointer surface is no longer
working as intended.
Since we no longer re-use the same surface, we can delete the old surface
on pointer exit, along with any callbacks set on it. Then a frame callback
will be recreated naturally. This lets us remove the now broken kludge
from the past and restore animated cursor functionality.

Wayland signals (wl_signal) do not reliably handle changes to the
notification list during signal emission. Such scenarios occasionally
come up and can be difficult to investigate and debug.
This commit introduces the weston_signal_emit_mutable() function which can be
used in place of wl_signal_emit() and safely implements the following
behavior regarding notification list changes:
1. Listeners deleted during a signal emission and which have not already been
notified at the time of deletion are not notified by that emission.
2. Listeners added during signal emission are ignored by that emission.
The implementation of weston_signal_emit_mutable() is copied from the
wlr_signal_emit_safe() function of the wlroots project.

Walking the format/modifier list to try to find out if our FB is
compatible with the plane is surprisingly expensive. Since the plane's
capabilities are static over the lifetime of the KMS device, cache the
set of planes for which the FB is theoretically
format/modifier-compatible when it's created, and use that to do an
early cull of the set of acceptable planes.

When we first create a drm_fb from a weston_buffer, cache it and keep it
alive as long as the buffer lives. This allows us to reuse the gbm_bo
and kernel-side DRM framebuffer, rather than constantly creating and
destroying them at every repaint. The overhead of doing so (e.g. MMU
updates) can be significant on some platforms.

Currently each drm_fb takes a reference on a client buffer it wraps.
This prevents us from being able to reuse a drm_fb in multiple places
(e.g. two views of the same client buffer) simultaneously, or even back
to back.
Move the buffer reference to the plane state, as preparation for
allowing drm_fb to be cached inside the weston_buffer.
Signed-off-by: Daniel Stone <daniels@collabora.com>
Currently we take a reference on the underlying client buffer every time
we materialise a drm_fb from a view, and release it when the drm_fb is
destroyed. This means that we need to create and destroy a drm_fb every
time we want to use it, which is pathologically unperformant on some
platforms.
To start working towards being able to cache drm_fb, only take the
reference when we apply it to a plane state.

As the drm-smoke test randomly reports having the connector disabled,
and with it libseat reports setMaster errors, this enables DRM backend
debug messages for the kernel, and for libseat in an attempt to
track down the issue, whenever it might happen again.
These are pretty harmless, in terms of data being generated as we only
have a single DRM test using VKMS, and the libseat debug message aren't
that verbose, so we're safe keeping them for the time being.

In commit "libweston: add initial dma-buf feedback implementation" we've
added initial support to dma-buf feedback, but it was not using the
feedback from DRM-backend to add useful per-surface feedback.
In this patch we add this. The scanout tranche of the per-surface
feedback is based on the union of formats/modifiers of the primary and
overlay planes available. These are intersected with the
formats/modifiers supported by the renderer device.
Also, it's important to mention that the scene can change a lot and we
can't predict much. So this patch also adds hysteresis to the dma-buf
feedback. We wait a few seconds to be sure that we reached stability
before adding or removing the scanout tranche from dma-buf feedback and
resending them. This help us to avoid spamming clients and leading to
unnecessary buffer reallocations on their end.
Here's an example of what we want to avoid:
1. We detect that a view was not placed in a plane only because its
format is not supported by the plane, so we add the scanout tranche
to the feedback and send the events.
2. A few milliseconds after, the view gets occluded. So now the view
can't be placed in a plane anymore. We need to remove the scanout
tranche and resend the feedback with formats/modifiers optimal for
the renderer device. The client will then reallocate its buffers.
3. A few milliseconds after, the view that was causing the occlusion
gets minimized. So we got back to the first situation, in which the
format of the view is not compatible with the plane. Then we need to
add a scanout tranche and resend the feedback...

The initial dma-buf feedback implementation gives support to send

feedback support is very basic and is still not implemented in the
DRM-backend, what basically means that KMS plane's formats/modifiers are
not being exposed to clients. In the next commits of this series we add
the DRM-backend implementation.
