this paper describes how to partition a cache so that media workloads
do not completely trash the L1 cache.  we will almost certainly need
to implement this because GPU workloads are READ-PROCESS-WRITE, and
even having the data in the L1 cache *at all* is completely pointless
as it's never going to be accessed more than once.
