Linus, The following changes since commit 1a5304fecee523060f26e2778d9d8e33c0562df3: Merge tag 'parisc-for-6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux (2023-05-03 19:41:59 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to 7a8016d95651fecce5708ed93a24a03a9ad91c80: Merge tag 'kvm-s390-next-6.4-2' of https://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD (2023-05-05 06:15:09 -0400) This includes the 6.4 changes for RISC-V, and a few bugfix patches for other architectures. For x86, this closes a longstanding performance issue in the newer and (usually) more scalable page table management code. If you wish, you can take a look at commit d4fba4dfdcce1 to see the RISC-V conflicts and their resolution. ---------------------------------------------------------------- RISC-V: - ONE_REG interface to enable/disable SBI extensions - Zbb extension for Guest/VM - AIA CSR virtualization x86: - Fix a long-standing TDP MMU flaw, where unloading roots on a vCPU can result in the root being freed even though the root is completely valid and can be reused as-is (with a TLB flush). s390: - A couple bugfixes. ---------------------------------------------------------------- Andrew Jones (1): RISC-V: KVM: Alphabetize selects Anup Patel (10): RISC-V: KVM: Add ONE_REG interface to enable/disable SBI extensions RISC-V: KVM: Allow Zbb extension for Guest/VM RISC-V: Add AIA related CSR defines RISC-V: Detect AIA CSRs from ISA string RISC-V: KVM: Drop the _MASK suffix from hgatp.VMID mask defines RISC-V: KVM: Initial skeletal support for AIA RISC-V: KVM: Implement subtype for CSR ONE_REG interface RISC-V: KVM: Add ONE_REG interface for AIA CSRs RISC-V: KVM: Use bitmap for irqs_pending and irqs_pending_mask RISC-V: KVM: Virtualize per-HART AIA CSRs Claudio Imbrenda (2): KVM: s390: pv: fix asynchronous teardown for small VMs KVM: s390: fix race in gmap_make_secure() David Matlack (1): KVM: RISC-V: Retry fault if vma_lookup() results become invalid Paolo Bonzini (3): Merge tag 'kvm-riscv-6.4-1' of https://github.com/kvm-riscv/linux into HEAD Merge tag 'kvm-x86-mmu-6.4-2' of https://github.com/kvm-x86/linux into HEAD Merge tag 'kvm-s390-next-6.4-2' of https://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux into HEAD Sean Christopherson (1): KVM: x86: Preserve TDP MMU roots until they are explicitly invalidated arch/riscv/include/asm/csr.h | 107 +++++++++- arch/riscv/include/asm/hwcap.h | 8 + arch/riscv/include/asm/kvm_aia.h | 127 +++++++++++ arch/riscv/include/asm/kvm_host.h | 14 +- arch/riscv/include/asm/kvm_vcpu_sbi.h | 8 +- arch/riscv/include/uapi/asm/kvm.h | 51 ++++- arch/riscv/kernel/cpu.c | 2 + arch/riscv/kernel/cpufeature.c | 2 + arch/riscv/kvm/Kconfig | 10 +- arch/riscv/kvm/Makefile | 1 + arch/riscv/kvm/aia.c | 388 ++++++++++++++++++++++++++++++++++ arch/riscv/kvm/main.c | 22 +- arch/riscv/kvm/mmu.c | 28 ++- arch/riscv/kvm/vcpu.c | 194 +++++++++++++---- arch/riscv/kvm/vcpu_insn.c | 1 + arch/riscv/kvm/vcpu_sbi.c | 247 ++++++++++++++++++++-- arch/riscv/kvm/vcpu_sbi_base.c | 2 +- arch/riscv/kvm/vm.c | 4 + arch/riscv/kvm/vmid.c | 4 +- arch/s390/kernel/uv.c | 32 +-- arch/s390/kvm/pv.c | 5 + arch/s390/mm/gmap.c | 7 + arch/x86/kvm/mmu/tdp_mmu.c | 121 +++++------ 23 files changed, 1208 insertions(+), 177 deletions(-) create mode 100644 arch/riscv/include/asm/kvm_aia.h create mode 100644 arch/riscv/kvm/aia.c
