Sure, I will investigate that. What about the ticket which LIjo raised which was basically doing 8 resets instead of one  ? Lijo - can this ticket wait until I come up with this new design for amdgpu reset function or u need a quick solution now in which case we can use the already existing patch temporary.

I am not sure why HIVE is the object we should work with, hive is one use case, single device is another, then Lijo described something called partition which is what ? Particular pipe within GPU ?. What they all share in common
IMHO is that all of them use reset domain when they want a recovery operation, so maybe GPU reset should be oriented to work with reset domain ?

Yes, exactly that's the idea.

Basically the reset domain knowns which amdgpu devices it needs to reset together.

If you then represent that so that you always have a hive even when you only have one device in it, or if you put an array of devices which needs to be reset together into the reset domain doesn't matter.

Maybe go for the later approach, that is probably a bit cleaner and less code to change.
