In an attempt to clarify the license terms of all files in the libcamera
project, the build system files deserve particular attention. While they
describe how the binaries are created, they are not themselves
transformed into any part of binary distributions of the software, and
thus don't influence the copyright on the binary packages. They are
however subject to copyright, and thus influence the distribution terms
of the source packages.
Most of the meson.build files would not meet the threshold of
originality criteria required for copyright protection. Some of the more
complex meson.build files may be eligible for copyright protection. To
avoid any ambiguity and uncertainty, state our intent to not assert
copyrights on the build system files by putting them in the public
domain with the CC0-1.0 license.

The IPA, IPC and Stream tests are self-contained so they can run in
parallel.

Test that the IPC supports sending data and file descriptors over the
IPC medium. To be able to execute the test two parts are needed, one
to drive the test and act as the libcamera (master) and a one to act as
the IPA (slave).
The master drives the testing posting requests to the slave to process
and sometimes respond to. A few different tests are performed.
- Master sends an array to the slave which responds with a reversed copy
of the array. The master verifies that a reversed array is returned.
- Master tries to send an empty message making sure that the send call
fails.
- Master sends a list of file descriptors and ask the slave to calculate
and respond with the sum of the size of the files. The master verifies
that the calculated size is correct.
- Master sends a pre-computed size and a list of file descriptors and
asks the slave to verify that the pre-computed size matches the sum of
the size of the file descriptors.
- Master sends two file descriptors and asks the slave to join the file
contents in a new file and respond with its file descriptor. The
master then verifies that the content of the returned file descriptor
matches the order of the original two files.
