Hi Paolo, We have the following KVM RISC-V changes for 6.4: 1) ONE_REG interface to enable/disable SBI extensions 2) Zbb extension for Guest/VM 3) AIA CSR virtualization 4) Few minor cleanups and fixes Please pull. Please note that the Zicboz series has been taken by Palmer through the RISC-V tree which results in few minor conflicts in the following files: arch/riscv/include/asm/hwcap.h arch/riscv/include/uapi/asm/kvm.h arch/riscv/kernel/cpu.c arch/riscv/kernel/cpufeature.c arch/riscv/kvm/vcpu.c I am not sure if a shared tag can make things easy for you or Palmer.
