Dear All
I am recently using qemu-system-arm to boot a linux uImage.
I would like to do some dynamic instrumentation on the uncompressed kernel.
It seems that I need to focus on two key points.
Firstly, I need to know when the kernel is uncompressed, which means the
compression process is finished. By analyzing the vmlinux.elf and the
trace I can figure it out.
Secondly, I need to know where the uncompressed is, which means where the
uncompressed linux kernel (Before translated into tcg) stores in the
virtual address of qemu. Does anyone have ideas? Many Thanks
Regards
Muhui
