[igt-dev] [PATCH i-g-t 5/5] RFC: tests/intel/xe_create: example for useing macro for multi-gpu testing

[Kamil Konieczny]

Sample code extends existing create-massive-size subtest to run
on multi-GPUs boards with the help of new functions and macros,
this should work without --drivers or IGT_DRIVERS options
but have some limitations that it will not display opened device
at proper child.
