Okay, but I've also noticed that a WriteReq generally carries no data. Why exactly is that? Cause
if we are writing to memory, then the memory access latency shouldn't be 0 right?
I believe that happens if the write got its data by snooping a cache.
The packet still goes to the memory, but with the write suppressed.
This certainly happens in the Timing case; I admit I'm a little less
clear about the Atomic one.
Sorry - I see I was responding about a read.
So, what surprises me is that you're saying that write requests generally
carry no data. That doesn't seem right. What leads you to that conclusion?
