This series implements KVM Guest Debug on RISC-V. Currently, we can debug RISC-V KVM guest from the host side, with software breakpoints. A brief test was done on QEMU RISC-V hypervisor emulator. A TODO list which will be added later: 1. HW breakpoints support 2. Test cases This series is based on Linux 6.7-rc6 and is also available at: https://github.com/Du-Chao/linux/tree/riscv_gd_sw The matched QEMU is available at: https://github.com/Du-Chao/qemu/tree/riscv_gd_sw Chao Du (3): RISC-V: KVM: Enable the KVM_CAP_SET_GUEST_DEBUG capability RISC-V: KVM: Implement kvm_arch_vcpu_ioctl_set_guest_debug() RISC-V: KVM: Handle breakpoint exits for VCPU arch/riscv/include/uapi/asm/kvm.h | 1 + arch/riscv/kvm/vcpu.c | 15 +++++++++++++-- arch/riscv/kvm/vcpu_exit.c | 4 ++++ arch/riscv/kvm/vm.c | 1 + 4 files changed, 19 insertions(+), 2 deletions(-) -- 2.17.1
