Hi All,
What is a "functional access" in M5? In port.hh there is a comment saying:
"/** Function called by the associated device to send a functional
access,
an access in which the data is instantly updated everywhere in the
memory system, without affecting the current state of any block or
moving the block.
*/"
But I'm still not very clear what is it used for? Could anyone give me
some examples?
Besides, I need to use the CPU id in class LRU and Cache. So I need to
make sure that the contextID (CPU id, right? I guess...) in the request
in each Packet properly set. However, I found this information in the
packet passing along the functional access not properly set (with a very
large number).
Thanks.
