Subject: [RFC PATCH 1/3] config: provide a fragment to enable gdb for qemu
Date: Thu, 13 Dec 2018 13:29:08 +0100 [thread overview]
Message-ID: <20181213122910.24193-2-anders.roxell@linaro.org> (raw)
In-Reply-To: <20181213122910.24193-1-anders.roxell@linaro.org>
Adding a fragment to make it easier to know what options is needed to
build a kernel to get the that you can debug in qemu.
First you need to start qemu with flags '-s -S' and then connect with
gdb like below:
$ gdb \
./obj-dir/vmlinux -iex 'add-auto-load-safe-path \
./obj-dir' -ex 'target remote localhost:1234'
