This patch adds the tooling for incorporating files as C data, so that
files can be built into the binaries. The tool is in Python to avoid
adding extra dependencies like xxd.
xxd.py is copied from Mesa as-is, from commit
b729cd58d76f97f3fc04a67569535ee5ef2f5278 (master branch on 2021-01-26),
a.k.a 21.0-branchpoint-635-gb729cd58d76.
Moving the GLSL vertex shader into a separate file is not that
interesting, the purpose of this commit is to provide a simple
demonstration of the tooling. The real benefits come in a following
patch where the fragment shaders are re-written and externalized.

This is purely moving code as is with no changes other than making the
three functions non-static.
Originally this was part of "gl-renderer: Requirement based shader
generation" by Harish Krupo, but that patch made also big changes to the
code at the same time. Patches are easier to review when code movement
is separate from behavioral changes, therefore I introduced this patch.

The main point here is to print "GL ES %d.%d" instead of "GL ES 2"
because GL-renderer can and will use GL ES 3 features when present.
Saying it's GL ES 2 renderer is not quite true.
To print that, I need to extract major, minor from gr->gl_version and
those didn't have ready made macros yet. While writing the extraction,
make all these trivial functions, so that the compiler might warn us if
one passes e.g. negative literal numbers to gr_gl_version(). Explicit
types help keeping the bit operations safe too.
The only purpose for GR_GL_VERSION_INVALID was to fall back to version
2.0. Moving the fallback and logging into get_gl_version() makes that
macro unnecessary.
Finally, just in case GL version string contained garbage, reject
negative version numbers.

This test ensures that client submitted damage goes to the screen

The added quirk is explained in the test that uses it.

For a pbuffer EGLSurface, assume that EGL swap behavior is "preserved"
which means buffer age is always 1 (after the very first
eglSwapBuffers()).
EGL pbuffers are always single-buffered.
Mesa EGL Surfaceless platform does not seem to expose EGL_EXT_buffer_age
that could have told us the same. Hence all repaints to pbuffer surfaces
used to need to repaint the whole output always. This patch makes
repainting only the latest damage possible.
Repainting only the latest damage is required for a future test on
output damage regions: "tests: add output damage test".
Technically, setting buffer_age to 1 is not correct before the very
first eglSwapBuffers(), but to keep the code simpler I chose to rely on
a newly enabled output always having full damage anyway.
Checking that EGL_SWAP_BEHAVIOR is EGL_BUFFER_PRESERVED would do too.
Unfortunately, Mesa seems to return EGL_BUFFER_DESTROYED, so I cannot
fail the headless-backend in that check. Even so, the output damage test
actually succeeds.

If full output damage is forced every time a screenshot is taken, the
test suite cannot take screenshots of damage as that would depend on
repainting only the damaged area.
Stop damaging the output and instead just schedule a repaint so the
screenshot can be taken. This is safe because:
- if any views were promoted to hw planes previously,
weston_output_disable_planes_incr() would force them to be demoted at
assing_planes() time causing damage via weston_view_move_to_plane()
- even when hardware primary plane has no damage, DRM-backend will not
skip calling to the renderer after commit
"drm-backend: do not skip renderer if capturing screen".
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
The renderer must be called for any pending screen capture to complete.
Previously this was guaranteed by weston_screenshooter_shoot() forcing
full output damage, so damage was never empty. If the future,
screenshooting stops inflicting damage, and the damage on the primary
plane even after disabling hardware planes may be empty.
This patch ensures that screenshots do not get stuck until damage
occurs.

I am working on adding a test to ensure Weston repaints damage
correctly, where I rely on Weston repainting exactly and only the damage
submitted by a client. That means I have to stop screenshooting from
damaging everything automatically. Doing that, I noticed that
screenshots on DRM-backend could theoretically get stuck if I do that.
So test for it.

This was prompted by a recent discussion on #dri-devel IRC channel,
where the use of pseudonyms to maintain anonymity was said to be a
normal and accepted practice. See:
https://people.freedesktop.org/~cbrill/dri-log/index.php?channel=dri-devel&highlight_names=&date=2021-02-09
and look for the discussion around pq and Lyude.
Until then, I was hesitant to accept Signed-off-by's with names that
looked very much not a real name.
Clarify our documentation that pseudonyms are ok.
Note, that is not what the Linux kernel documentation says today in
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst
which says that pseudonyms are not ok. According to the discussion, this
should probably be fixed in the kernel too.
Since we are now ok with pseudonyms in Signed-off-by, there is no reason
left to accept any patches without a Signed-off-by. This clarifies our
policy and takes the burden of case-by-case consideration away from
maintainers.
The wording about needing to use a personal email address is my
addition. The intention is to ensure a globally unique handle for a
person while that person remains anonymous, so that the Signed-off-by
cannot be mistaken for someone elses.

This allows tests to give a meaningful name for their fixture setups
when they use more than one of them.
If a test uses DECLARE_FIXTURE_SETUP_WITH_ARG(), it must now pass a
third argument naming the field which is struct fixture_metadata. This
also means that the fixture setup data must now be a struct, it cannot
be a plain type anymore. A compiler error is generated if the field type
is not the expected one.
All tests using DECLARE_FIXTURE_SETUP_WITH_ARG() and converted to the
new form and given names for their fixture setups.
The fixture setup names not actually used yet, that will be another
patch.

The conclusion (quite a while ago, too) was that requiring Meson 0.52 is
fine. Mesa does that too. Bump the requirement to 0.52.1 which is the
last release of the 0.52 series.
This allows all issues listed in #296 to be worked on. It also allows
switching to TAP in the test suite for more detailed reports.

This allows Gitlab to show a detailed test report in a human friendly
manner on a merge request page.
The junit output depends on Meson 0.55, but Meson in CI is bumped to the
latest release on Feb 15th. It is beneficial to use the newest
possible Meson in CI even if we do not require it, so that we benefit
from fixes, e.g. new warnings about accidentally using more recent
Meson features than our minimum Meson version supports.
Meson 0.57 is required for proper test names in the Gitlab report after
switching the tests to TAP. See:

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
color. This avoids having to consider chroma siting when sub-sampling.
This way all the test cases can use the same reference image.

Require GL_EXT_unpack_subimage unconditionally in GL-renderer. Without
this extension, it would take considerable effort in GL-renderer to
handle correctly images that contain row padding, either as a temporary
copy to remove padding or doing SubImage updates row by row.
I would guess that this path has gone long completely untested, and if
it was exercised, the rows never had padding thanks to 32-bit pixel
formats. Instead of writing tests to poke the corner cases and fixing
it, remove it.
This will make it easier to fix other problems in GL-renderer in this
area in the future - one less path to consider and many restrictions in
GL API gone.

If the launcher is told to use a non-default seat (not seat0), there
will not be a VT or tty to set up. VT/tty setup requires privileges.
This patch allows a non-root user to use launcher-direct, provided that
the seat is not the default. There is still the problem of opening DRM
and input devices, which is left for the user to solve.
This mode of operation is useful for developers who can set up a
secondary seat on their machine. You can run Weston/DRM from a terminal
window by pointing it to a non-default seat. You have to arrange a
DRM device by having an extra unused graphics card in the machine. You
also need dedicated input devices. Both the DRM device and the input
devices must be assigned to the secondary seat and device file
permissions adjusted so that they can be opened.
Doing so is an obvious security risk, as input could easily be
eavesdropped.

Some panels advertise both pointer/touch capabilities but without having

use USB as a communication tunnel to transfer/send out input events.
As we can't really tell if they're fake or not, only advertise to

We handle it at lower level as that allows to handle the case where
removal of a real pointer should also remove the cursor from being
