Vanshidhar Konda asked for the simplest test "to verify that the kernel can submit and hardware can execute batch buffers on all the command streamers in parallel." We have a number of tests in userspace that submit load to each engine and verify that it is present, but strictly we have no selftest to prove that the kernel can _simultaneously_ execute on all known engines. (We have tests to demonstrate that we can submit to HW in parallel, but we don't insist that they execute in parallel.) v2: Improve the igt_spinner support for older gen.
