fb0 通过 memory-region 关联到 display_reserved 这块 reserved memory 上面; of_reserved_mem_device_init include/linux/of_reserved_mem.h 传入参数 dev, 找到 dev 中 memory-region 对应的 reserved memory .然后调用 reserved_memory 对象的 ops->device_init( reserved_memory * rmem, device * dev ); 8...

Device drivers such as this, that make numerous decisions based upon the state of data read from the MMIO region would be a good target for attack. Each MMIO Read operation is synchronized with mem fences / spin locks, but we didn’t see any evidence that this code synchronizes in-between...
