Bibo Mao d38e31ef74 target/loongarch/kvm: Add software breakpoint support With KVM virtualization, debug exception is injected to guest kernel rather than host for normal break intruction. Here hypercall instruction with special code is used for sw breakpoint usage, and detailed instruction comes from kvm kernel with user API KVM_REG_LOONGARCH_DEBUG_INST. Now only software breakpoint is supported, and it is allowed to insert/remove software breakpoint. We can debug guest kernel with gdb method after kernel is loaded, hardware breakpoint will be added in later.
