Hi experts,
I'm using a Juno r1 board for some cache-related research experiment so I'm studying the related memory attributes such as cacheability and shareability.
I found the manual mentioned that: " the division between inner and outer is IMPLEMENTATION DEFINED".
However, I tried to search the answer in the juno manual while I don't find any detailed definition about the inner / outer domains?
Does anyone know how to find these concepts for Juno?
Thank you in advance.

Hi, I think that for Juno... wrt the cache settings: The L1/L2 CPU caches are going to be inner and there is no outer system cache (in the interconnect) for Juno. wrt shareability: the interconnect (CCI-400) doesn't differentiate between inner & outer. But, the bL system is effectively in a single inner shareable domain. FWIW Linux only supports inner shareable mappings by default. HTH MarkN.
