The benefit of only resetting a single engine is that we leave other streams of userspace work intact across a hang; vital for process isolation. We had wired up individual engine resets for gen6, but only enabled it from gen8; now let's turn it on for the forgotten gen7. gen6 is still a mystery as how to unravel some global state that appears to be reset along with an engine (in particular the ppgtt enabling in GFX_MODE).
