newer version(>=5.2.0) of qemu-system-aarch64 cannot debug arm64 linux kernel Description of problem: Steps to reproduce: 1. Run QEMU in on teminal. 2. Run gdb-multiarch in another terminal, for example: gdb-multiarch ./linux-5.10.4/vmlinux 3. In gdb-multiarch, enter three commands in sequence:"target remote localhost:1234"、"b do_sys_open"、"continue" 4. GDB breakpoint cannot take effect 5. If using qemu-system-aarch64 5.0.0(manually compiled),GDB breakpoint can take effect. Additional information: I tested this problem using different combinations: Host Os:Ubuntu18/Ubuntu20/Ubuntu22 ARM64 Linux Kernel: 5.4.50/5.10.4 QEMU:qemu 2.11/qemu 4.2/qemu 5.0/qemu 5.2/qemu 6.2/qemu 7 Finally, I found out that arm64 linux kernel cannot be debugged since qemu-system-aarch64 5.2.0.
