I confirm it on my SKL and BDW:
# ./gem_exec_reloc --r gtt-32
IGT-Version: 1.18-g137360f (x86_64) (Linux:
4.11.0-rc2-tip-series-without-cover-letter+ x86_64)
Test requirement not met in function intel_require_memory, file intel_os.c:293:
Test requirement: __intel_check_memory(count, size, mode, &required, &total)
Estimated that we need 2 objects and 8,193 MiB for the test, but only have
3,388 MiB available (RAM) and a maximum of 786,980 objects
Last errno: 2, No such file or directory
Subtest gtt-32: SKIP (0.222s)
