Subject: [PULL 4/9] i386/kvm: Require KVM_CAP_IRQ_ROUTING
Date: Thu, 15 Oct 2020 12:44:56 -0400 [thread overview]
Message-ID: <20201015164501.462775-5-ehabkost@redhat.com> (raw)
In-Reply-To: <20201015164501.462775-1-ehabkost@redhat.com>
KVM_CAP_IRQ_ROUTING is available since 2009 (Linux v2.6.30), so
it's safe to just make it a requirement on x86.
