Hi, can anyone tell me how gem5 handles the uncacheable write? For example. maybe there is an inst which is a memory write, but this write is to change the frame buffer value, then this request should be uncacheable? Am I right here? In this case, how gem5 handles it? Does this request go to cache? In cache_impl.cc the function access(), if it is uncacheable, we just flush it. But we will use this value of the memory write no matter what, because we need this value to change the LCD. So could any one tell me what's going on? Where should we store this data? Thanks a lot.
regards Xiangyang
