Hi Amin,
The writing back of dirty cache state using functional accesses is already part
of the draining afaik. I am not sure that is very useful as a cache flush
mechanism though. I'd suggest to do it "properly" If you care about performance.

Subject: [gem5-users] Cache flushing in classic cache model
Hi,
I'd like to implement a cache flushing mechanism to writeback dirty lines to
memory in classic cache model. I am using timing memory model, but currently
don't care about getting the correct timing. As a first step, I would like to
get the correct functionality without worrying about timing (i.e., all
writebacks happen instantly). To implement it, I am thinking of iterating
through all lines and then write back the dirty ones using functional accesses.
I don't know if a similar mechanism is already implemented or if there is a
better way to implement cache flushing?
Overall, any insights on this would be appreciated.
Thanks,
Amin
