Hi Paolo, We have the following KVM RISC-V changes for 6.13: 1) Accelerate KVM RISC-V when running as a guest 2) Perf support to collect KVM guest statistics from host side In addition, the pointer masking support (Ssnpm and Smnpm) for KVM guest is going through the RISC-V tree. I also have Svade and Svadu support for host and guest in my queue which I will send in the second week of the merge window to avoid conflict with the RISC-V tree. Please pull. Regards, Anup The following changes since commit 81983758430957d9a5cb3333fe324fd70cf63e7e: Linux 6.12-rc5 (2024-10-27 12:52:02 -1000) are available in the Git repository at: https://github.com/kvm-riscv/linux.git tags/kvm-riscv-6.13-1 for you to fetch changes up to 332fa4a802b16ccb727199da685294f85f9880cb: riscv: kvm: Fix out-of-bounds array access (2024-11-05 13:27:32 +0530) ---------------------------------------------------------------- KVM/riscv changes for 6.13 - Accelerate KVM RISC-V when running as a guest - Perf support to collect KVM guest statistics from host side ---------------------------------------------------------------- Anup Patel (13): RISC-V: KVM: Order the object files alphabetically RISC-V: KVM: Save/restore HSTATUS in C source RISC-V: KVM: Save/restore SCOUNTEREN in C source RISC-V: KVM: Break down the __kvm_riscv_switch_to() into macros RISC-V: KVM: Replace aia_set_hvictl() with aia_hvictl_value() RISC-V: KVM: Don't setup SGEI for zero guest external interrupts RISC-V: Add defines for the SBI nested acceleration extension RISC-V: KVM: Add common nested acceleration support RISC-V: KVM: Use nacl_csr_xyz() for accessing H-extension CSRs RISC-V: KVM: Use nacl_csr_xyz() for accessing AIA CSRs RISC-V: KVM: Use SBI sync SRET call when available RISC-V: KVM: Save trap CSRs in kvm_riscv_vcpu_enter_exit() RISC-V: KVM: Use NACL HFENCEs for KVM request based HFENCEs Björn Töpel (1): riscv: kvm: Fix out-of-bounds array access Quan Zhou (2): riscv: perf: add guest vs host distinction riscv: KVM: add basic support for host vs guest profiling Yong-Xuan Wang (1): RISC-V: KVM: Fix APLIC in_clrip and clripnum write emulation arch/riscv/include/asm/kvm_host.h | 10 ++ arch/riscv/include/asm/kvm_nacl.h | 245 ++++++++++++++++++++++++++++++++++++ arch/riscv/include/asm/perf_event.h | 6 + arch/riscv/include/asm/sbi.h | 120 ++++++++++++++++++ arch/riscv/kernel/perf_callchain.c | 38 ++++++ arch/riscv/kvm/Kconfig | 1 + arch/riscv/kvm/Makefile | 27 ++-- arch/riscv/kvm/aia.c | 114 +++++++++++------ arch/riscv/kvm/aia_aplic.c | 3 +- arch/riscv/kvm/main.c | 63 +++++++++- arch/riscv/kvm/mmu.c | 4 +- arch/riscv/kvm/nacl.c | 152 ++++++++++++++++++++++ arch/riscv/kvm/tlb.c | 57 ++++++--- arch/riscv/kvm/vcpu.c | 191 +++++++++++++++++++++------- arch/riscv/kvm/vcpu_sbi.c | 11 +- arch/riscv/kvm/vcpu_switch.S | 137 ++++++++++++-------- arch/riscv/kvm/vcpu_timer.c | 28 ++--- 17 files changed, 1022 insertions(+), 185 deletions(-) create mode 100644 arch/riscv/include/asm/kvm_nacl.h create mode 100644 arch/riscv/kvm/nacl.c
