2018-09-12	dev-arm: rename Pl390 to GicV2	Ciro Santilli
	The Pl390 model has evolved and acquired a lot of the features from GICv2, which means that the name is no longer appropriate. Rename it to GICv2 since this is more representative of the supported features. GICv2 is backwards compatible with the older Pl390, so we decided to simply rename the class to represent both GICv2 and older interfaces such as the instead of creating a new separate one.

2017-02-14	arm, kvm: remove KvmGic	Curtis Dunham
	KvmGic functionality has been subsumed within the new MuxingKvmGic model, which has Pl390 fallback when not using KVM for fast emulation. This simplifies configuration and will enable checkpointing between KVM emulation and full-system simulation.

2017-02-14	arm, kvm: implement MuxingKvmGic	Curtis Dunham
	This device allows us to, when KVM support is detected and compiled in, instantiate the same Gic device whether the actual simulation is with KVM cores or simulated cores. Checkpointing is not yet supported. Change-Id: I67e4e0b6fb7ab5058e52c933f4f3d8e7ab24981e Reviewed-by: Andreas Sandberg <andreas.sandberg@arm.com>
2017-02-14	sim, kvm: make KvmVM a System parameter	Curtis Dunham
	A KVM VM is typically a child of the System object already, but for solving future issues with configuration graph resolution, the most logical way to keep track of this object is for it to be an actual parameter of the System object.

2015-06-01	kvm, arm, dev: Add an in-kernel GIC implementation	Andreas Sandberg
	This changeset adds a GIC implementation that uses the kernel's built-in support for simulating the interrupt controller. Since there is currently no support for state transfer between gem5 and the kernel, the device model does not support serialization and CPU switching (which would require switching to a gem5-simulated GIC).
