Hi all, I just want to do a very simple task. I'm using QEMU for debugging a new OS and I see that there is a memory region that is being updated by an unknown task. I don't know if it's another process or the kernel itself.
So I would like to put a physical memory watchpoint. I don't know how to do that. As the GDB stub is operating using virtual addressing, I cannot place a watchpoint on an address as it's not stopping. To make it short, I want the equivalent of the Bochs command "watch write addr", which inserts a write watch point at physical address 'addr'. I haven't seen this is possible on the QEMU monitor...
