AMD 3D V-Cache Performance Optimizer Driver Posted For Linux
AMD today quietly posted a new open-source Linux kernel driver for review..
This interface sets a bias to alter the CPU core reordering depending upon whether you are desiring higher frequences or larger L3 cache usage for your application(s). For those that were hoping all future AMD 3D V-Cache processors would boast CCDs with all the same large L3 caches, the work on this driver now seems to indicate that this won't necessarily be the case. Given today is the first time this Linux driver has been publicly posted, it would seem that at least some future AMD processor models will continue with only a subset of the CCDs having the big cache sizes.
