While get_presentation() will only ever be called once (making the caching of
the return value moot), it is good to stop using the static variable as it
would cause surprising problems if anyone adds more tests here and runs it
under the new test harness.
It was leaked before and continues to be so.

Using static data will mess things up when the test harness no longer fork()'s
each sub-test. Hence it needs to be converted to "normal" data.
Unfortunately here the cached value was actually used, so keeping that
behaviour is a handful. Yes, it was all leaked also before.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
Just one test call this only once, so the cached value will never be useful.
Stop using static data, it sets a bad example. If more tests were added, things
would start failing when forking is removed from the test harness.

I cannot see any reason why this should be static data. But if it is static
data, it will prevent re-entering wet_main() to run tests with this plugin, so
replace it with "normal" data.

This caching is actually never hit. I tested by making the early return abort()
instead and all works just fine.
Remove the caching. The static variable will cause problems when we stop
fork()'ing for each test case.

As we avoid importing the buffer in the GPU, when attaching the buffer
we'll not have a valid image to retrieve it from, and as such we'll
avoid touching and setting the surface state shader.
This adds also 'direct_display' to the surface state and with it, sets the
surface state 'direct_display' member whenever the imported buffer will
have the direct-display member set.

Adds a new callback 'can_scanout_dmabuf' in weston_backend, which
can be set by the back-end do determine if the buffer supplied can be
imported directly by KMS.
This patch adds a wrapper over it, 'weston_compositor_dmabuf_can_scanout'
which is called before importing the dmabuf in the GPU if the
direct_display dmabuf is being set. If that's true and the check
failed, we refuse to create a wl_buffer.
This patch avoids importing in the GPU.

This comment was added in 230f3b1bf8 with the
intent that if we had an information table about pixel formats (which we do
have today), we could implement more sanity checks like ensuring that width
pixels fit into stride.
Daniel Vetter said on #dri-devel IRC recently:
< danvet> since userspace shouldn't look at stride for buffers with
modifiers, only pass it around unchanged
I asked for clarification. It was expected that userspace would not do any kind
of sanity checks as modifiers could change everything.
Let's remove the misleading code comment so that people don't get the idea of
adding more well-intended but ill-advised sanity checks. If more checks are
added, they must take the modifier into account, which the existing checks do
not do.
After 5 years, it is far too late to remove our existing sanity checks, but we
can attempt to not cause any more damage that would restrict what people can do
in the kernel.

In this manner we will allow views to reach the overlay (or underlays)
even if the damage tracking will detect that the new view will
occlude the view underneath it.
Renames occluded_region to planes_region, and uses occluded_region
to represent the region where we add each view's visible-and-opaque region.
Sprinkle some comments about each region.
Re-uses the view's clipped region to determine visible-and-opaque region
which is accumulated (for both renderer and HW planes cases) into
occluded_region. The current view's clipped_region is then checked against
occluded_region.

We can determine if the pixel format used by the clients buffer is
scan-out capable much sooner, so do it when constructing the zpos
candidate list. It also removes the checks in their respective
prepare_ functions.
Avoids the situation where we'd need to retrieve the DRM framebuffer each time
when checking the pixel format.

In order to better optimize view assignment to HW planes, we construct
an intermediary zpos candidate list which is used aggregate all suitable
planes for handling scan-out capable client buffers.
We go over it twice: once to construct it and once to pick-and-choose a
suitable plane based its highest zpos position.
In order to maintain the view order correctly we track current zpos
value being applied to the plane state and use it when trying to place
a view into a plane.
Pass the computed zpos value to be applied to the plane state.

This is based on the assumption that overlays are in between cursor and
primary plane and it is required to be able to assign views to planes,
even if the driver doesn't not expose such property.
As we hard-code them as immutable the commit part would not need any
further modifications.

Due to an error in driving GitLab, this commit erroneously contained the
entirety of !267 (zpos support in the KMS backend) squashed into one
single commit, pushed into master.
In order to keep the history clean, this is being reverted; a rebased
version of !267 with the clear individual commits which were already
present will be applied in its place.
This reverts commit 95e3b0deae.
The remoting plugin currently has a set_gbm_format() hook, which accepts
GBM_FORMAT_* tokens from the host to set as a supported format.
GBM_FORMAT_* values are strictly aliased with DRM_FORMAT_*.
In order to avoid an extra unnecessary dependency from the remoting
plugin on GBM, switch to using the formats from libdrm instead.
This fixes a compile error seen when the remoting plugin is enabled:
../remoting/remoting-plugin.c:39:10: fatal error: gbm.h: No such file or directory
39 | #include <gbm.h>
| ^~~~~~~
compilation terminated.
The error was caused by not having any dependency at all on GBM from
the remoting backend, which is fixed here by adding a new dependency on
the libdrm headers for drm_fourcc.h.

timeline subscription
When subscribing over the command line to the 'timeline' scope we hit
the situation where we could emit a timeline message but without the
weston_output object being (fully) enabled. The timeline subscription
object requires to install its own callback on the 'destroy_signal' but
at that time, the 'destroy_signal' is not initialized.
This moves 'destroy_signal' initialization before timeline has a chance
to emit a timeline subscription message for that weston_output.
While at it, move also 'frame_signal' initialization before any function
call to keep them nicely organized.
