Reply-To: neversetsun@ustc.edu, qemu-devel@nongnu.org List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Hi,all: I think memory access monitoring is useful in debugging a target running in qemu. There are two ways to do this(or even more): 1.x86 specific. add debug register emulation in qemu. 2.hardware independent. such as adding a command in qemu monitor. I would like to know if anybody has already done this? Or is there any problem that prevents from doing so? best wishes, shizheng
