[PATCH v2 OLK-5.10 0/2] mm: arm64: Add NUMA kernel and user replication feature
by Nikita Panov 18 Apr '25

18 Apr '25

Initial support for NUMA RO-data replication. You can enable replication for a specific process or for a whole memory cgroup. Processes: /proc/$PID/numa_table_replication 0 - table replication disabled. 1 - tables for RO-data are replicated. 2 - all tables are replicated. /proc/$PID/numa_data_replication 0 - data is not replicated. 1 - hot RO-data is replicated. 2 - all RO-data is replicated. (May not work properly now, avoid if possible) Cgroups: /sys/fs/cgroup/memeory/$CGNAME/memory.numa_table_replication same as for processes. /sys/fs/cgroup/memeory/$CGNAME/memory.numa_data_replication 0 - data is not replicated. 1 - hot RO-data is replicated. 2 - hot RO-data is replicated and on adding to cgroup all existing RO-data of a process is replicated. 3 - all RO-data is replicated. (May not work properly now, avoid if possible) Entry numa_replication_stats shows the amount of replicated data in a process or a cgroup.

[PATCH OLK-6.6 0/8] iommu/arm-smmu-v3: Use KVM VMID for s2 stage
by lishusen 18 Apr '25

18 Apr '25

On an ARM64 system with a SMMUv3 implementation that fully supports Broadcast TLB Maintenance(BTM) feature as part of the Distributed Virtual Memory(DVM) protocol, the CPU TLB invalidate instructions are received by SMMUv3. This is very useful when the SMMUv3 shares the page tables with the CPU(eg: Guest SVA use case). For this to work, the SMMUv3 must use the same VMID that is allocated by KVM to configure the nested stage 2(S2) translations. Jean-Philippe Brucker (1): iommu/arm-smmu-v3: Enable broadcast TLB maintenance Kunkun Jiang (1): vfio: Fix kabi breakage due to closing VFIO_CONTAINER Shameer Kolothum (6): KVM: Add generic infrastructure to support pinned VMIDs KVM: arm64: Introduce support to pin VMIDs KVM: arm64: Add interfaces for pinned VMID support iommufd: Associate kvm pointer to iommufd ctx iommu: Pass in kvm pointer to domain_alloc_user iommu/arm-smmu-v3: Use KVM VMID for s2 stage arch/arm64/include/asm/kvm_host.h | 3 + arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/arm.c | 14 ++++ arch/arm64/kvm/vmid.c | 84 ++++++++++++++++++++- drivers/iommu/amd/iommu.c | 1 + drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c | 46 +++++++++-- drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.h | 1 + drivers/iommu/intel/iommu.c | 1 + drivers/iommu/iommufd/hw_pagetable.c | 5 +- drivers/iommu/iommufd/iommufd_private.h | 3 + drivers/iommu/iommufd/main.c | 14 ++++ drivers/iommu/iommufd/selftest.c | 1 + drivers/vfio/device_cdev.c | 3 + drivers/vfio/vfio.h | 2 + include/linux/iommu.h | 9 ++- include/linux/iommufd.h | 7 ++ include/linux/kvm_host.h | 18 +++++ virt/kvm/Kconfig | 3 + virt/kvm/kvm_main.c | 23 ++++++ 19 files changed, 225 insertions(+), 14 deletions(-) -- 2.33.0
