This patchset does not contain any in-kernel acceleration stuff. This patchset does not enable DDW for emulated devices. Changes: v4: * addressed Ben's comments * big rework with moving tce_xxx callbacks out of ppc_md v3: * applied multiple comments from Gavin regarding error checking and callbacks placements v2: * moved "Account TCE pages in locked_vm" here (was in later series) * added counting for huge window to locked_vm (ugly but better than nothing) * fixed bug with missing >>PAGE_SHIFT when calling pfn_to_page Alexey Kardashevskiy (16): rcu: Define notrace version of list_for_each_entry_rcu and list_entry_rcu KVM: PPC: Use RCU for arch.spapr_tce_tables mm: Add helpers for locked_vm KVM: PPC: Account TCE-containing pages in locked_vm powerpc/iommu: Fix comments with it_page_shift powerpc/powernv: Make invalidate() a callback powerpc/spapr: vfio: Implement spapr_tce_iommu_ops powerpc/powernv: Convert/move set_bypass() callback to take_ownership() powerpc/iommu: Fix IOMMU ownership control functions powerpc: Move tce_xxx callbacks from ppc_md to iommu_table powerpc/powernv: Release replaced TCE powerpc/pseries/lpar: Enable VFIO powerpc/powernv: Implement Dynamic DMA windows (DDW) for IODA vfio: powerpc/spapr: Reuse locked_vm accounting helpers vfio: powerpc/spapr: Use it_page_size vfio: powerpc/spapr: Enable Dynamic DMA windows arch/powerpc/include/asm/iommu.h | 33 ++- arch/powerpc/include/asm/kvm_host.h | 1 + arch/powerpc/include/asm/machdep.h | 25 -- arch/powerpc/include/asm/tce.h | 38 +++ arch/powerpc/kernel/iommu.c | 158 ++++++++----- arch/powerpc/kernel/vio.c | 5 +- arch/powerpc/kvm/book3s.c | 2 +- arch/powerpc/kvm/book3s_64_vio.c | 43 +++- arch/powerpc/kvm/book3s_64_vio_hv.c | 6 +- arch/powerpc/platforms/cell/iommu.c | 9 +- arch/powerpc/platforms/pasemi/iommu.c | 8 +- arch/powerpc/platforms/powernv/pci-ioda.c | 239 ++++++++++++++++--- arch/powerpc/platforms/powernv/pci-p5ioc2.c | 4 +- arch/powerpc/platforms/powernv/pci.c | 86 ++++--- arch/powerpc/platforms/powernv/pci.h | 16 +- arch/powerpc/platforms/pseries/iommu.c | 77 ++++-- arch/powerpc/sysdev/dart_iommu.c | 13 +- drivers/vfio/vfio_iommu_spapr_tce.c | 348 ++++++++++++++++++++++++---- include/linux/mm.h | 3 + include/linux/rculist.h | 38 +++ include/uapi/linux/vfio.h | 37 ++- mm/mlock.c | 49 ++++ 22 files changed, 990 insertions(+), 248 deletions(-) -- 2.0.0
