Is there any GIC architecture version 3.0 specification available ? I could not find it online.
Thanks
The GICv3 Architecture Specification is not yet publicly released. I would suggest contacting ARM's support team:
https://silver.arm.com/
In case you haven't spotted it, the spec is now on infocenter.
Thanks, It is most definitely not light reading! A lot of work has obviously gone into its design and it'll take some effort on my part to understand it reasonably well..
