[PATCH v2] KVM: arm/arm64: vgic: Add debugfs vgic-state file

2017-01-24 Thread Christoffer Dall
Add a file to debugfs to read the in-kernel state of the vgic. We don't do any locking of the entire VGIC state while traversing all the IRQs, so if the VM is running the user/developer may not see a quiesced state, but should take care to pause the VM using facilities in user space for that
