> Always skip missing engines to make tests skips very early and avoid
> losing time in tests which need to do setups or waits before they would
> otherwise detect this.
> 
> To ensure PMU is rejecting opening missing engines we will add an explicit
> test later.
> 
> v2: Use subtest groups for engine checking. (Chris Wilson)
