[RFC PATCH 0/4] target/riscv/kvm: QEMU support for KVM Guest Debug on RISC-V

[Chao Du <duchao@eswincomputing.com>]

This series implements QEMU 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 QEMU 8.2.0-rc4 and is also available at:
https://github.com/Du-Chao/qemu/tree/riscv_gd_sw

This is dependent on KVM side changes:

Chao Du (4):
  target/riscv/kvm: add software breakpoints support
  target/riscv/kvm: implement kvm_arch_update_guest_debug()
  target/riscv/kvm: handle the exit with debug reason
  linux-headers: enable KVM GUEST DEBUG for RISC-V
