Hi community,
I can think of 2 ways to use gdb+qemu to remotely debug arm64 kernel, by
enabling gdbstub within qemu to communicate with gdb.
I am wondering in the real-world practice, is this debug technique
helpful for debugging arm64 kernel?
Options are:
1) Host environment: qemu is running as kvm hypervisor
i) armv8 foundation model running arm64 kernel
ii) or a real armv8 Linux machine running arm64 kernel
Qemu guest environment: arm64 kernel
2) Host environment: x86 linux machine running qemu as tcg aarch64 emulator
Qemu guest environment: arm64 kernel
Prerequisite: qemu-aarch64 needs to be reliable.
-- Thanks,
Xuebing Wang
