Hi Chris,

The engine names are now stored inside the iterator and not as static

But we are not using them later. Your patch just copies and frees
an array.
They are used inside an igt_info() in the child processes. Output at the
moment is quite strange.
I also don't get this - child has a copy of everything how can it not work?
A copy of what? The intel_engine_data is scoped to the for_each_engine
loop. We're leaking pointers to locations on stack, so they get
clobbered and we print garbage in %s.
I misread the the patch while glancing it as forking being done inside
the for_engine_loop.
