To whom it may concern, I want to know how and when QEMU updates the RAM for the simulator when there is a write request sent from cache. For example, when there is a memory_op_write which is a cache miss or when there is a memory_op_update which is an evicted dirty block from cache. Since there is no real data handled in the cache hierarchy, I wonder when the real data is updated in the main memory, and how the CPU gets the real data to compute? Now I know I can use loadvirt() to fetch the real data from the QEMU's memory, I still want to know when I can fetch the updated real data of a "write" block or an evicted dirty block.
Thanks, Yingying
