Subject: [Gems-users] interaction with cache controller

Hello All,

I would like to interact with Ruby's cache controller
dynamically. For example, by sending flags to the
cache controller so that it takes certain
actions/transitions. My main goal is to provide
prefetching hints from the program itself to the cache
controller. One way to establish interaction between
programs and Ruby is to use magic instructions, but I
believe this will not work in my case as magic
instructions are dynamic and the cache controller's
behavior is generated at compile time. Is there a way
to establish such interaction?

Another way to modify the cache controller behavior at
run time could involve monitoring the address bus and
checking to see if certain registers/memory locations
have been accessed. Is it possible to monitor the
address bus and add this functionality to the cache
controller? If yes, can you give me a sense of how
much work is involved and where to start?

Also, is it possible to access registers via Ruby or
should this be done at a lower level? Thank you very
much.

Regards,

Dave
