+but if not use with parameter "-machine virt -cpu cortex-a57",The breakpoint can be set successfully.
+
+2. Set hardware breakpoint with lldb command "breakpoint set -H -a 0xFFFF800080000000" not report error, but can't hint breakpoint. I try set breakpoint on a old x86 MacOS, It will hint breakpoint successfully.
+
+3. I also try run qemu-system-x86_64 emulator on apple silicon mac, It also can't hint hardware breakping. The command is:
+```
+qemu-system-x86_64 -machine q35,accel=tcg -smp cpus=8  \\
+  -kernel arch/x86/boot/bzImage \\
+  -append "okaslr"\\
