Something you might like to add is:

	igt_subtest_group {
		igt_fixture igt_require(intel_gen(devid) >= 12);

		igt_describe("Test OA TLB invalidate");
		igt_subtest("gen12-oa-tlb-invalidate")
			gen12_test_oa_tlb_invalidate();

		igt_describe("Measure performance for a specific context using OAR in Gen 12");
		igt_subtest("gen12-unprivileged-single-ctx-counters")
		...
	}

To combat the redundancy and add some visual grouping.
