The overlap variable is sufficient to determine from where to start
displaying the contents of the ring buffer. Also redundant to verify
if the position in the buffer went over the maximum size.

Having a (single) global variable which others depend on it implies
having a single flight recorder present. Until we have a reason to

With it add also a function which can be used in an assert()-like
situation to display the contents of the ring buffer. Within gdb
this call also be called if the program is loaded/still loaded into
memory.
The global variable will be used in a later patch to be accessed from a
python gdb script.

Remove unnecessary ifdefs for DRM_MODE_CONNECTOR_DSI, DRM_MODE_CONNECTOR_DPI.
They are both provided by libdrm and were introduced long before 2.4.83 (the
lowest version we currently support).

Since commit 28d26483 ("build: bump libdrm requirement to newer version
(2.4.83)"), all supported libdrm versions provide modifier formats,
atomic API and blob formats. Remove ifdef checks (HAVE_DRM_ADDFB2_MODIFIERS,
HAVE_DRM_ATOMIC, HAVE_DRM_FORMATS_BLOB) to improve the code and make it
simpler.

There are some features that are available only if the user's libdrm version is
not too old: format modifiers require at least libdrm 2.4.71, atomic API at
least 2.4.78 and blob formats at least 2.4.83.
Bump libdrm to 2.4.83 (the oldest version that support these features) in order
to be able to remove ifdef checks and simplify the code. Major distributions
already support libdrm 2.4.91, so it's safe to apply this commit.

Mode change from mixed-mode to renderer-only means we should no longer
try to place views in HW planes (as we composite everything into the
primary plane) thus we should avoid that whenever that happens.
In the same time we need to be able to place in mixed-mode/renderer-only
mode the cursor view into the cursor plane (if one is available).
This patch adds a further check to skip plane assignment when disabling
overlay support (when we switch to renderer-only mode), when drivers do
not have atomic-modeset or it has been disabled intentionally.

Adds a further assert() to make sure we're not checking against invalid

overlay resulting in a check for invalid zpos values.

when switching to mixed-mode of compositing
This way we avoid an (incorrect) duplicate check of zpos values. Also,
this would be needed because the renderer needs have the lowest zpos value
available as we don't (yet) properly support underlays, the primary
plane serves as our renderer.
Adds also a check to see if we try to assign a view to a plane with
a lower zpos value than the one assigned to the primary when switching
to mixed-mode of compositing.

Nothing is using FAIL_TEST or FAIL_TEST_P and that is good. Remove them to not
encourage using them.
If we need a test that should fail, it always needs to fail in a very specific
way which needs to be checked. For this we have e.g. expect_protocol_error().
We never want a fail-test to pass because it failed in a way we did not expect.
Therefore these macros are useless.

Successful tests should just return, not call exit() which breaks the new test
harness when it uses TAP.

When we move on to TAP, stdout will be reserved for TAP and stderr is for free
chatter. Set up an example that tests should use testlog() instead of fprintf
or printf to chat in the right place.
Most statements were already printing to stderr, so this just makes then a
little shorter. There are also some statements that printed to stdout and are
now corrected.

Using the test name for the reference images will stop working when the new

This reverts 50b7b70835.
We didn't make Meson create a logs directory, so writing the images fails

even less expectation that it would write somewhere else than CWD by default.

Initially, `_XWAYLAND_ALLOW_COMMITS` was introduced in commit 7ace831ca
to avoid drawing the window content before it's ready to be shown.
But a repaint might also be triggered by the client damages before the
XWM has finished drawing its window decorations and drop shadows, which
previously was not too much of an issue since the XWM could still
finish updating the X11 window after the buffer was submitted.
However, with the addition of multiple window buffers in Xwayland [1]
which are aimed at preventing the X11 clients from updating the buffer
after it's been committed, this is no longer possible.
As a result, the use of multiple window buffers in Xwayland can cause
ugly repainting effects of the decorations if the buffer is submitted
before the XWM has finished painting its decorations.
Use the X11 property `_XWAYLAND_ALLOW_COMMITS` can be used to avoid
this, by controlling when Xwayland should commit changes to the Wayland
surface.

This is necessary for the test harness to be able to execute the compositor
multiple times in the same process. As we never unload opened modules, the
first compositor iteration will leave them all loaded and following compositor
iterations will then have them already loaded.

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

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.

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 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.
