Hi Tvrtko,
Engine->id namespace is per-tile so struct igt_live_test->reset_engine[]
needs to be two-dimensional so engine reset counts from all tiles can be
stored with no aliasing. With aliasing, if we had a real multi-tile
platform, the reset counts would be incorrect for same engine instance on
different tiles.

sorry for being late here... the patch makes sense to me and the
CI failures don't look related.

Thanks pushed!
There is more work to be done with the fact i915_reset_engine_count has
it's own aliasing when used like this, but I opted to leave that for
some other time.
