[igt-dev] [PATCH i-g-t 0/2] Add support for KUnit tests

[Isabella Basso]

This patch series was first developed as part of the LKCamp hackathon
that happened last year[1], mainly focusing on refactoring DRM tests to
use KUnit.

KUnit[2][3] is a unified test framework that provides helper tools,
simplifying their development and execution. Using an x86-64 machine
it's possible to run tests in the host's kernel natively using user-mode
Linux[4] (aka UML), which simplifies usage in a wide variety of
scenarios, including integration to CI.

As the tool's adoption widens into graphics testing territory, I and
LKCamp members figured it would be important to support it in IGT, as
it's a core tool for GPU drivers maintainers.

I have then added KUnit support into IGT mainly following the KTAP
specs, and it can be tested using patch 2/2 in this series together with
an AMDGPU patch series[5] available at [6].
