> Commit 870c774b866c ("igt/gem_exec_nop: Add expectancy of independent
> execution between engines") extended a "basic" subtest (now
> "basic-series") with a pass/fail metric based on comparison of parallel
> execution time to be less than an average * 2.  Since then, that limit
> has been raised quite a few times:
> - by commit 41a26b5152a5 ("igt/gem_exec_nop: Relax parallel assertion
>   for short rings") to maximum + minimum,
> - by commit 7bd4f918c461 ("igt/gem_exec_nop: Explain the parallel
>   execution assertion") to maximum + minimum * 10/9,
> - by commit a0eebbddecaa ("igt/gem_exec_nop: Relax assertion for
>   parallel execution") to sum * 2.
> 
> With the criteria relaxed up to that extent, the purpose of that check
> has been limited to a showcase for an old GuC failure.  Since that is
> now obsolete, kill that assert.
