Subject: [Qemu-devel] Using qemu to debug arm64 linux kernel
Date: Mon, 03 Mar 2014 17:28:41 +0800 [thread overview]
Message-ID: <53144B49.8010407@gmail.com> (raw)
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
