Hello, all I added a custom device to qemu. This device is attached to sysbus by mmio and has an address register in which device should access the guest memory the register point to. I write a bare-metal program that pass an address like 0x1234ABCD to this address register. Inside qemu device code I added, if device reads value from register and directly accesses this value of 0x1234ABCD, it will access host memory 0x1234ABCD rather than guest memory 0x1234ABCD. Does qemu provide some functions that allow device to access guest memory address?
Thanks, Kaiyuan Liang
