Subject: [PATCH v1 00/13] powerpc: kvm: Enable in-kernel acceleration for VFIO
Date: Tue, 15 Jul 2014 19:25:20 +1000 [thread overview]
Message-ID: <1405416333-12477-1-git-send-email-aik@ozlabs.ru> (raw)
This enables in-kernel acceleration of TCE hypercalls (H_PUT_TCE,
H_PUT_TCE_INDIRECT, H_STUFF_TCE). This implements acceleration
for both real and virtual modes.
This was made on top of both:
[PATCH v1 00/16] powernv: vfio: Add Dynamic DMA windows (DDW)
[PATCH v1 0/7] powerpc/iommu: kvm: Enable MultiTCE support
Alexey Kardashevskiy (13):
KVM: PPC: Account TCE pages in locked_vm
KVM: PPC: Rework kvmppc_spapr_tce_table to support variable page size
KVM: PPC: Enable IOMMU_API for KVM_BOOK3S_64 permanently
KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_VFIO capability number
KVM: PPC: Reserve KVM_CAP_SPAPR_TCE_64 capability number
KVM: PPC: Add @offset to kvmppc_spapr_tce_table
KVM: PPC: Add support for 64bit TCE windows
KVM: PPC: Add hugepage support for IOMMU in-kernel handling
KVM: PPC: Add page_shift support for in-kernel H_PUT_TCE/etc handlers
KVM: PPC: Fix kvmppc_gpa_to_hva_and_get() to return host physical
address
KVM: PPC: Associate IOMMU group with guest copy of TCE table
KVM: PPC: vfio kvm device: support spapr tce
KVM: PPC: Add support for IOMMU in-kernel handling
