ARMv9-AArch64

Is there any plan to add ARMv9-A ARCH64 support?

Hello @JerryFan0913! Sorry for the (huge) delay!

Can you explain better what you mean by support for Armv9? From what I undestand, the base ISA for v9 is pretty much the same as v8, so Bao should just run in a v9 core out-of-the-box.

The only thing I can think of is exploring CCA to improving partitioning using the GPTs. If so, yes, you have looked at the specification and came up with some ideas on how to support this within Bao. However, we are expecting to get our hands in real hardware to get our hands dirty and explore these capabilities.

Do you have any ideas on how to explore the Armv9 features? Do you have any other features besides CCA in mind?
