Added cLUT profile creation to validate linearization algorithm
for DToB3 tag (direction dev to PCS). The 3DLUT is
built by using raw matrix conversion from dev to XYZ and reverse
(XYZ to device).
The test uses floating point pipeline, known as unbounded mode of LCMS.
The details are described in ICCSpecRevision_02_11_06_Float.pdf
The purpose of these new test cases is to keep the GL-renderer 3D LUT
path tested even after color-lcms and GL-renderer start using
specialized matrix-shaper paths.
These also exercise build_eotf_from_clut_profile() in color-lcms, but do
not actually verify it. These cases only test that the recovered EOTF
and its inverse produce an identity mapping together.
BT.2020 is not used in these tests, because the RGB-XYZ conversion
matrix does not stay inside [0.0, 1.0] in either direction, which would
be a problem for the 3D LUT element in the multiProcessingElement
pipelines. Handling that would have been possible, but testing with
AdobeRGB color space should suffice while keeping the test code from
being even more complicated.
roundtrip_verification() tests that we succeed in creating cms
pipelines correctly in both directions so that the resulting ICC file is
better behaved. The Weston test itself only cares about the BToD
direction.

This adds a new test helper library that depends on LittleCMS 2.
For starters, the library implements conversion from enum transfer_fn to
ICC multiProcessingElements compatible LittleCMS curve object.
That conversion allows encoding transfer funtions in ICC files and
LittleCMS pipelines with full float32 precision instead of forcing a
conversion to a 1D LUT which for power-type curves is surprisingly
imprecise.
This also adds CI tests to make sure the conversion matches our
hand-coded transfer functions.

This a new matrix inversion test written from scratch to be suitable for
running in CI: quick to run and automatically detects success/failure.
This all is a result of what I learnt while working on
https://gitlab.freedesktop.org/pq/fourbyfour
Computing the residual error with infinity norm comes straight from
fourbyfour documentation on how to evaluate matrix inversion error.
Most of the hard-coded test matrices have been generated with fourbyfour
project as well, as it contains the generator code. The matrices are
hard-coded here also to make testing faster, but primarily because the
generator code needs BLAS and LAPACK, and having those as Weston
dependencies would be far too much just for this.
Now, if someone wants to modify weston_matrix stuff, we should at least
detect matrix inversion and multiplication bugs.

This test program was useful a decade ago when weston_matrix_invert()
was being developed. It was a manual test program that ran for a certain
number of seconds and required human interpretation of numbers to see if
results were acceptable or not. Hence it was foundamentally unsuitable
for CI.
The way it generated random matrices for inversion testing was also very
naive, and it used the determinant value to determine invertability
which is completely bogus. This made it also a bad test for correctness.
Much better speed and correctness testing is implemented in
https://gitlab.freedesktop.org/pq/fourbyfour
with documented testing procedures. It has a copy of the weston_matrix
implementation.

shell-utils contains a number of helpers which are currently in use by
both desktop-shell and kiosk-shell. In order to extend this use to
fullscreen-shell as well (which can benefit from reusing the
weston_curtain infrastructure to be able to create solid-colour views
which may or may not be opaque, as well as one function within
fullscreen-shell which was copied wholesale to shell-utils), we need to
create a separate Meson dependency object, and avoid the existing
pattern of including the source from shared/ within the source list for
each shell.
This requires creating a new top-level directory for these shared helper
functions which are required by each shell, but are not part of
libweston in and of itself.
shell-utils depends on libweston-desktop; libweston-desktop depends on
libweston; libweston depends on shared.
Thus it is not possible to expose a dependency object from the shared/
directory which declares a dependency on the libweston-desktop
dependency, as Meson processes directories in order and resolves
variable references as they are parsed.
In order to break this deadlock, this commit creates a new top-level
directory called 'shell-utils' containing only this file, which can be
parsed by Meson after libweston-desktop (making the libweston-desktop
Meson dependency variable available to the build file to declare a
dependency on that), but before the shells (making the new Meson
depenendency object available to each shell which wishes to use it).
This commit contains no functional changes to any observable code.

This is probably the simplest case to demonstrate how to use
WESTON_EXPORT_FOR_TESTS.
Previously, vertex-clip test re-built vertex-clipping.c for itself. Now
it directly links in gl-renderer.so instead as that is where
vexter-clipping.c gets built into for actual use. This probably will not
work for any installed program, but luckily tests are never installed,
so Meson makes sure the DSO is found.
Unfortunately we cannot remove the definition of dep_vertex_clipping
yet, because clients/cliptest.c needs it.
This makes vertex-clip test depend on GL-renderer, but that is where the
code is really used.

1. Use fixture_setup to set the generated by LCMS output profile based on
given chromaticities and white points. The following list of well known
chromaticities:
- sRGB
- adobe RGB
- bt2020
and white point is D65. Use INTENT_ABSOLUTE_COLORIMETRIC to avoid BPC.
Input profile is always sRGB and it is used internally by Weston as
stock profile.
2. Use these hardcoded matrixes as part of pipeline 1DLUT->3x3->1DLUT.
The diagnostic code to retrieve the transform matrix is availble into
test in the comments. The conversion matrixes generated for the
following cases:
- sRGB to sRGB (unity)
- sRGB to adobeRGB
- sRGB to BT2020
3. Compare GPU shaders(gl texture3D) vs manual pipeline calculation
Use different max tolerable error per transform.
There are comments how number of points in 3DLUT is related to tolerance.
Tolerance depends more on the 1D LUT used for the inv EOTF than
the tested 3D LUT size: 9x9x9, 17x17x17, 33x33x33, 127x127x127.
4. Enable build matrix-shaper test if color-management-lcms is enabled.

ERROR: Job failed: execution took longer than 5m0s seconds
That is hitting both kinds of timeouts at the same time: the per-test

That run seems to have had a particularly ill fortune, as a simple retry
finished the same job in 2 minutes, and the longest running test took
only 24 seconds.
Nevertheless, by Daniel Stone's suggestion let's bump both timeouts:
- the per-test timeout to 120 seconds, which with the multiplier in CI
goes up to 8 minutes
- the job timeout for all build related jobs to 15 minutes
The timeout for tests_standalone is not bumped as we are not adding
significant amounts of new tests there.

Instead of checking just the monotonicity of the blending results, this
changes the alpha-blending test to compute the reference blend result
itself and then comparing to the compositor result. This way we can be
sure that the compositor implements the exact correct formula and not
something that just looks nice, as verifying the reference images are
actually correct is hard.
The reference image is renamed to follow the fact that this is not
primarily a monotonicity test anymore. The reference image is also
redundant, but I think it has documentary value.
The #if 0'd block of code was very useful in figuring out blending
errors in a future test case, so it is included here. I have a feeling
we are going to need it again.

This adds a test to ensure that the wl_shm formats YUV420, NV12 and YUYV
are decoded and converted to RGB correctly in GL-renderer.
The test deliberately uses a 256 x 256 test image so that effects from
width vs. pitch vs. stride cannot be observed, and row padding is zero.
Also padding between planes is zero. Attempting to use a test image with
less "round" dimensions lead to stride mismatch in GL-renderer, likely
due to GL_UNPACK_ALIGNMENT being left at value 4. It is unclear if YUV
wl_shm buffers' row stride needs to be aligned to 4 bytes or not, so I
did not pursue fixing it. GL-renderer seems to be confusing width, pitch
and stride even further, and not e.g. allow padding with ARGB buffers.

Furthermore, the test arranges so that each 2x2 pixel block has the same

Currently doesn't exist a standard way to write a weston.ini inside a test.
Here, two new functions `weston_ini_setup` and `cfgln` are introduced to
help the test writer to write a weston.ini file and load it to the test.
And `internal-screenshot-test` is converted to use the new method of write
a weston.ini. This conversion serves as example and initial API test.
The tester needs to call `weston_test_harness_execute_as_client` or
`weston_test_harness_execute_as_plugin` in the same way as before.
The `weston_ini_setup` will fill the setup->config_file with the
correct path to the weston.ini file.
The main design goal is to avoid pre-made or build-made weston.ini(s)
and keep the test as self-contained as possible.

With this patch we add support to run DRM-backend tests locally
in the test suite. For now this won't work in the CI, as there
are no cards available. But the plan is to achieve this by using
VKMS (virtual KMS) in the future.
To run DRM-backend tests locally, first of all the user has to
set the environment variable WESTON_TEST_SUITE_DRM_DEVICE to
'card0', 'card1' or any other device where he wants to run
the tests. Also, for now it only works if it is run as root,
but in the future this problem will be solved.
The tests will run on a non-default seat. The reason for that
is that we want to avoid opening input devices unnecessarily.
Also, since DRM-backend usage requires gaining DRM master status
on a DRM KMS device, nothing else must be using the device at
the same time. To achieve this we use a lock to run the
DRM-backend tests sequentially.

This goes through all output transforms with two different buffer transforms
and verifies the visual output against reference images.
This commit introduces a new test input image 'basic-test-card.png'. It is a
small image with deliberately odd and indivisible dimensions to provoke bad
assumptions about image sizes. It contains red, green and blue areas which are
actually text that makes it very obvious if you have e.g. color channels
swapped. It has a white thick circle to highlight aspect ratio issues, and an
orange cross to show a mixed color. The white border is for contrast and a 1px
wide detail. The whole design makes it clear if the image happens to be rotated
or flipped in any way.
The image has one pixel wide transparent border so that bilinear sampling
filter near the edges of the image would produce the same colors with both
Pixman- and GL-renderers which handle the out-of-image samples fundamentally
differently: Pixman assumes (0, 0, 0, 0) samples outside of the image, while
GL-renderer clamps sample coordinates to the edge essentially repeating the
edge pixels.
It would have been "easy" to create a full matrix of
every output scale & transform x every buffer scale & transform, but that
would have resulted in 2 renderers * 8 output transforms * 3 output scales *
8 buffer transforms * 3 buffer scales = 1152 test cases that would have all
ran strictly serially because our test harness has no parallelism inside one
test program. That would have been slow to run, and need a lot more reference
images too.
Instead, I chose to iterate separately through all output scales & transforms
(this patch) and all buffer scales & transforms (next patch). This limits the
number of test cases in this patch to 56, and allows the two test programs to
run in parallel.
I did not even pick all possible scale & transform combinations here, but just
what I think is a representative sub-set to hopefully exercise all the code
paths.

The ivi-layout-test comprises of two halves: the client and the plugin. This
migrates the test to the new test harness.
In the old harness, the plugin was built as the test in meson.build and it fork
& exec'd the client part. In the new harness client tests start from the client
program which sets up the compositor in-process, so now the client is built as
the test in meson.build and the plugin is just an additional file.
Therefore there is not need for the plugin for fork & exec anything anymore, so
all that code is removed.
