Re: ARM KVM guest virtual address to host virtual address Look up

Hi Peter: I want to trap some ldr,str instruction in guest VM for debug. Therefore, I have to emulate guest ldr,str in host. Without guest VA to host VA, I cannot emulate ldr,str instruction in host. Thank you -Jack 原始郵件 寄件者：Peter Maydell 傳送日期：Fri,
