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.
