Hi Victor,
Alternatively, you can also register an exit callback that will
calculate the stat. Have a look at how we use registerExitCallback().
One simple example is in the BaseTags class
(src/mem/cache/tags/base.{hh,cc}).

Hi Victor,
I have no idea if this will work, but have you tried using a lambda
function with whatever captures (e.g., [this]) that you need?
Cheers,
Jason

Hi,
I have created a stat of type Value called zeroBytesPercentage. It
is the percentage of zero bytes of all the lines that are written in
the LLC. I want it to get a value from a function
(calcZeroBytesPercentage), so I'm using functor.
zeroBytesPercentage
.functor(calcZeroBytesPercentage)
.flags(total)
.precision(3)
;
Throughout the program execution I'm populating a vector called
totalLines, which I've declared as public in BaseCache. This vector
stores all the cache lines that are written to the LLC during the
execution of the program.
My problem is that the function is not static and that it uses
non-static variables (the totalLines vector). I've tried having the
function as a member of either BaseCache or BaseCache::CacheStats,
but either way I'm getting errors about the use of non-static data
members.
How can I do this calculation at the end of the execution and be
able to access variables that are non-static?
