library which exposes DSC Power Facilities to userspace via an API

PAFLib is a IBM written library which exposes Power Architecture Facilities to userspace via an API. This includes the Data Stream Control Register Facility (DSCR) and the Event-Based Branching facility (EBB). Linux kernel 3.9 has exposed problem-state DSCR usage for ISA 2.06 (POWER7 - emulated) and ISA 2.07 (POWER8 - in hardware). Linux 3.10 has exposed the EBB facility.

The Data Stream Control Register (DSCR for short) of POWER processors is used to control the degree of aggressiveness of memory prefetching for load and store.
