I found the C++ runner hard to develop on, and we had stability issues and
outstanding feature needs that made me want something I felt good about
hacking on. Thus, Rewrite It In Rust of the deqp runner.
The new runner includes:
- Skip lists don't reshuffle the test list.
- Known-flake handling without resorting to skip lists (fixing our main CI
reliability issue on a3xx right now).
- Per-thread Vulkan shader caches should speed up VK CI runtime.
- Tracking of crashes separate from fails (so we can see progress on that
front).
- Logging of deqp stderr spam (particularly assertion failures!) in the CI
log.
- Integrated QPA filtering so we don't have bash perf issues for it.
- Logging of what caselist to go look at for a given error report (in red,
so it's easier to find in your CI log).
- The code is 1/3 unit tests, and easy to extend for more coverage.
- Non-LAVA CI runs create a failures.csv in artifacts that you can check
in as your deqp-*-fails.txt file.
- Test runtime is included in results.csv so you can debug how to speed up
your CI job.
- Pretty summary at the end of the run of slow/flaky/failed tests.
Since this is a new runner with a different RNG, the test groups are
shuffled one more time. This seems to result in some panfrost T720
stability issues (See its new deqp-panfrost-t720-flakes.txt), and one new
flake in freedreno a630.
