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.

The fast log2 works better if rho is squared, i.e.
fast_log2(sqrt(2)) == 0.4
0.5 * fast_log2(2) == 0.5
so just square rho, and always divide by 2 afterwards.

This is the start of doing CTS tests on merges to Mesa master. We use
the surfaceless platform so that we don't need to bother bringing up
weston or X11. The surface size is kept low to reduce runtime, but
this comes at the cost of many rendering tests skipping due to
too-small render targets (as we see the impact of Mesa on the shared
runner pool, we can reevaluate this and what set of CTS tests we want
to run).
We split the job up across 4 runners (each at 4 llvmpipe threads), so
that the job can load-balance across our shared runners and finish
sooner (since dEQP is very single-thread-performance bound).
