关于 “使用 KGDB 调试 Linux 内核”的一个更新的说明

很意外的，才知道，当用 qemu 的时候，连 KGDB 都不需要，直接 qemu -s -S 就可以了：）。所以原文有关部分稍微改了一下。
所以，qemu 可以这样启动：
qemu ${QEMU_ARGS} \
    -kernel "$VMLINUZ" \
    -S -s -p ${KGDB_TCPPORT} \
    -append "${KERNEL_CMDLINE}" \
    -hda "${QEMU_HDA}" >/dev/null &
脚本执行速度也快了很多。

Hello,

Thanks for pushing me thinking about this, I didn't know this feature of
qemu before. And I tried "qemu -s -S" just now, it seems that every
thing went smoothly. Ok, so now I think is that: when we use qemu for
debugging, we don't need kgdb :[...

Well, that's a surprise to me. But I do need kgdb, because I want to
debug my tablet with kgdb anyway ;)

Thanks for your information!
