It can and should be done with the evtchn driver. Even for tests I think it should return to kernel mode to perform hypercalls. Tests should not run in a "magic" mode that normal guests won't use. If there are failure cases where return to kernel isn't possible and some logging would be useful, perhaps writing to a memory buffer and retrieving this via a crash dump would be ok?
