GIC v3&4: Programming sequence of GIC Registers

Hello Rakesh,

in the ARM documentation web site you can find a very nice document that explains practical what are the steps to configure and program a GIC compliant with the GICv3/v4 Architecture Specifications.

This is the direct link to the doc:

I hope this helps.

That looks like a very useful document!

Thank you Carmelo for your kind response.,

I have downloaded and gone through that document. This document is helpful and is very clear, but it doesn't contain any information about Virtualization Concept (My 2nd question).

Can you please help me for the same.

Thanks,

Rakesh.
