No, it can be used from threads as well. > Should spin batches instead install an exit handler? Problem being ordering. Since other exit handlers may depend upon GPU activity, cancelling that GPU activity has to be done first. If we install an exit handler for an early spin batch, that will be run last, causing a GPU hang in the other handlers. Furthermore, the exit handlers are not run after subtests; there is no setup/teardown procedure other than trying to fit such into igt_subtest_group + igt_fixture, which isn't always feasible. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
