This patchset adds support for the new hcall H_RPT_INVALIDATE and replaces the nested tlb flush calls with this new hcall if support for the same exists. Changes in v5: ------------- - Included the h_rpt_invalidate page size information within mmu_pszie_defs[] as per David Gibson's suggestion. - Redid nested exit changes as per Paul Mackerras' suggestion. - Folded the patch that added tlbie primitives into the hcall implementation patch. v4: https://lore.kernel.org/linuxppc-dev/20210215063542.3642366-1-bharata@xxxxxxxxxxxxx/T/#t Bharata B Rao (3): powerpc/book3s64/radix: Add H_RPT_INVALIDATE pgsize encodings to mmu_psize_def KVM: PPC: Book3S HV: Add support for H_RPT_INVALIDATE KVM: PPC: Book3S HV: Use H_RPT_INVALIDATE in nested KVM Documentation/virt/kvm/api.rst | 18 +++ arch/powerpc/include/asm/book3s/64/mmu.h | 1 + .../include/asm/book3s/64/tlbflush-radix.h | 4 + arch/powerpc/include/asm/kvm_book3s.h | 3 + arch/powerpc/include/asm/mmu_context.h | 11 ++ arch/powerpc/kvm/book3s_64_mmu_radix.c | 27 +++- arch/powerpc/kvm/book3s_hv.c | 90 +++++++++++ arch/powerpc/kvm/book3s_hv_nested.c | 89 ++++++++++- arch/powerpc/kvm/powerpc.c | 3 + arch/powerpc/mm/book3s64/radix_pgtable.c | 5 + arch/powerpc/mm/book3s64/radix_tlb.c | 147 +++++++++++++++++- include/uapi/linux/kvm.h | 1 + 12 files changed, 388 insertions(+), 11 deletions(-) -- 2.26.2
