Subject: [PATCH 06/10] KVM: PPC: enable IOMMU_API for KVM_BOOK3S_64 permanently
Date: Tue, 16 Jul 2013 10:54:01 +1000 [thread overview]
Message-ID: <1373936045-22653-7-git-send-email-aik@ozlabs.ru> (raw)
In-Reply-To: <1373936045-22653-1-git-send-email-aik@ozlabs.ru>
It does not make much sense to have KVM in book3s-64bit and
not to have IOMMU bits for PCI pass through support as it costs little
and allows VFIO to function on book3s-kvm.
Having IOMMU_API enabled will make it unnecessary to have a lot of
IOMMU_API enabled, those files only accelerate user space emulated devices
which do not seem to be in use very often.
