[igt-dev] [PATCH i-g-t 5/7] i915/gem_compute: Add test which runs compute workload on i915

[Zbigniew Kempczyński]

This test is verbatim copy of xe_compute with driver open exception
(it opens i915 drm fd instead xe). Technically it is possible to
create single test code (open would try DEVICE_INTEL | DEVICE_XE)
but I resisted to that distinguishing i915 and xe version.
