Thanks Joanna for letting know. This is actually blocking development so I'm thinking we go ahead with a local change that we think will be best and then we can discuss that change when Soby is back. What do you think?

Thanks. It seems like we are converging. Would it make sense to set up a meeting to thrash out details? Any time this week will be preferable. Let me know what works for you. Arve and Peter are in Pacific time zone. Rest of us are based in UK I guess?

Hey Soby and Olivier, on systems that don't support S-EL2, SPMC functionality mostly, if not all, resides in EL3 right? Going by that convention, would it make sense to have SVE save and restore in EL3? We can make it part of SPMC code in EL3. For additional space we can make use of DDR carveout as Soby mentioned above. Moreover, if we make that context save and restore part enablement configurable at compile time, then platform can choose whether they want the functionality. Would it then be acceptable?
