Subject: [PATCH 03/19] KVM: PPC: Book3S HV: check the IRQ controller type
Date: Mon, 7 Jan 2019 19:43:15 +0100 [thread overview]
Message-ID: <20190107184331.8429-4-clg@kaod.org> (raw)
In-Reply-To: <20190107184331.8429-1-clg@kaod.org>
We will have different KVM devices for interrupts, one for the
XICS-over-XIVE mode and one for the XIVE native exploitation
mode. Let's add some checks to make sure we are not mixing the
interfaces in KVM.
