Indeed, the older venus patches would simply force the system to hard reset in EL1, and in EL2 there is a fault (but the system recovers without the hard reset.) I do have a further question, isn't the information we need somewhere inside a TZ managed context bank? Can we even see in there from userspace? I really am out of my league here, but I'm willing to do any testing needed on the hardware and I can use b4 with the best of them ;) -- steev
