Detailed Description
ItsProcess is a base coroutine wrapper which is spawned by the Gicv3Its module when the latter needs to perform different actions, like translating a peripheral's MSI into an LPI (See derived ItsTranslation) or processing a Command from the ITS queue (ItsCommand).
The action to take is implemented by the method:
virtual void main(Yield &yield) = 0; It's inheriting from Packet::SenderState since the generic process will be stopped (we are using coroutines) and sent with the packet to memory when doing table walks. When Gicv3Its receives a response, it will resume the coroutine from the point it stopped when yielding.
