[QUOTE="ronvalencia"][QUOTE="tormentos"] You are loosing your time i already show Ron that HSA is not something you active by software,HSA requires a design change which most PC lack,APU systems are HSA designs,i even quote from AMD own page.. https://www.youtube.com/watch?v=Me0g_FsgU0U

Equally important, the cache hierarchy was designed to integrate with x86 microprocessors. The GCN virtual memory system can support 4KB pages, which is the natural mapping granularity for the x86 address space - paving the way for a shared address space in the future. In fact, the IOMMU used for DMA transfers can already translate requests into the x86 address space to help move data to the GPU and this functionality will grow over time. Additionally, the caches in GCN use 64B lines, which is the same size as x86 processors. This sets the stage for heterogeneous systems to transparently share data between the GPU and CPU through the traditional caching system, without explicit programmer control. - page 10

The new GCN ISA was designed to facilitate industry standards. AMDs Heterogeneous System Architecture (HSA) is envisioned as a model for heterogeneous computing.
It defines how CPUs and GPUs communicate and includes a virtual ISA (the HSA Intermediate Language), which is hardware agnostic. HSAIL code is dynamically compiled for the underlying hardware, and thus compatible with CPUs and GPUs from any vendor. GCN fully supports HSAIL - page 11.

""The new GCN ISA was designed to facilitate industry standards."" From your own link the new GCN whats is the new GCN.? GCN2.? In the worst case scenario GCN new ISA was designed to facilitate the industry standard,which mean 7XXX series which mean every single GPU before GCN is not compatible,unless is redesign and re release.. You can't turn 2 separate memory pools into one by just updating a drive,and you can bump DDR3 to match GDDR5 speed on normal PC by driver or software,HSA is a design where the CPU and GPU are on the same die with a common memory address this is the whole process anything else is make up.http://www.eetimes.com/electronics-news/4235499/AMD-s-Macri-talks-Heterogeneous-systems-architecture?pageNumber=1
The architectural path for the future is clear, Macri declared. That path will be paved with the programming patterns established on Symmetric Multi-Processor (SMP) systems migrating to the heterogeneous world
Notice "Discrete GPU"with HSA.
