Paolo or Radim, Please do a pull from my kvm-ppc-next-4.21-1 tag to get a PPC KVM update for 4.21. The main new thing this time is an improvement to the nested HV KVM code so that if you have a nested hypervisor that has a PCI device which is actually emulated by the level 0 hypervisor, level 1 can pass that through to level 2 using VFIO and the accesses to the device by level 2 will be emulated by level 0 and the results passed down to level 2 correctly. Thanks, Paul. The following changes since commit fd65d3142f734bc4376053c8d75670041903134d: kvm: svm: Ensure an IBPB on all affected CPUs when freeing a vmcb (2018-11-27 12:50:42 +0100) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc tags/kvm-ppc-next-4.21-1 for you to fetch changes up to 95d386c2d2e7660a6447df1507a9845665dab7d8: KVM: PPC: Book3S HV: Allow passthrough of an emulated device to an L3 guest (2018-12-17 11:33:50 +1100) ---------------------------------------------------------------- PPC KVM update for 4.21 The main new feature this time is support in HV nested KVM for passing a device that is emulated by a level 0 hypervisor and presented to level 1 as a PCI device through to a level 2 guest using VFIO. Apart from that there are improvements for migration of radix guests under HV KVM and some other fixes and cleanups. ---------------------------------------------------------------- Bharata B Rao (1): KVM: PPC: Pass change type down to memslot commit function Paul Mackerras (4): KVM: PPC: Book3S HV: Fix race between kvm_unmap_hva_range and MMU mode switch KVM: PPC: Book3S HV: Map single pages when doing dirty page logging KVM: PPC: Book3S HV: Cleanups - constify memslots, fix comments KVM: PPC: Book3S HV: Flush guest mappings when turning dirty tracking on/off Suraj Jitindar Singh (9): KVM: PPC: Book3S PR: Set hflag to indicate that POWER9 supports 1T segments KVM: PPC: Book3S: Only report KVM_CAP_SPAPR_TCE_VFIO on powernv machines KVM: PPC: Book3S HV: Add function kvmhv_vcpu_is_radix() KVM: PPC: Book3S HV: Implement functions to access quadrants 1 & 2 KVM: PPC: Add load_from_eaddr and store_to_eaddr to the kvmppc_ops struct KVM: PPC: Update kvmppc_st and kvmppc_ld to use quadrants KVM: PPC: Book3S HV: Allow passthrough of an emulated device to an L2 guest KVM: PPC: Book3S: Introduce new hcall H_COPY_TOFROM_GUEST to access quadrants 1 & 2 KVM: PPC: Book3S HV: Allow passthrough of an emulated device to an L3 guest Yangtao Li (1): KVM: PPC: Book3S HV: Change to use DEFINE_SHOW_ATTRIBUTE macro arch/powerpc/include/asm/hvcall.h | 1 + arch/powerpc/include/asm/kvm_book3s.h | 21 +++-- arch/powerpc/include/asm/kvm_book3s_64.h | 15 +++- arch/powerpc/include/asm/kvm_host.h | 3 + arch/powerpc/include/asm/kvm_ppc.h | 10 ++- arch/powerpc/kernel/exceptions-64s.S | 9 +++ arch/powerpc/kvm/book3s.c | 5 +- arch/powerpc/kvm/book3s_64_mmu_hv.c | 12 ++- arch/powerpc/kvm/book3s_64_mmu_radix.c | 134 +++++++++++++++++++++++++++++-- arch/powerpc/kvm/book3s_hv.c | 95 +++++++++++++++++++--- arch/powerpc/kvm/book3s_hv_nested.c | 116 ++++++++++++++++++++++++-- arch/powerpc/kvm/book3s_hv_rm_mmu.c | 2 +- arch/powerpc/kvm/book3s_pr.c | 4 +- arch/powerpc/kvm/book3s_xics.c | 12 +-- arch/powerpc/kvm/book3s_xive.c | 12 +-- arch/powerpc/kvm/booke.c | 3 +- arch/powerpc/kvm/powerpc.c | 33 +++++++- arch/powerpc/mm/fault.c | 1 + 18 files changed, 418 insertions(+), 70 deletions(-)
