    Phoronix: AMD Publishes Open-Source Linux HSA Kernel Driver

    AMD has just published a massive patch-set for the Linux kernel that finally implements a HSA (Heterogeneous System Architecture) in open-source. The set of 83 patches implement a Linux HSA driver for Radeon family GPUs and serves too as a sample driver for other HSA-compatible devices. This big driver in part is what well known Phoronix contributor John Bridgman has been working on at AMD. Heterogeneous System Architecture has been talked up for a while now by AMD as well as ARM vendors and now finally for open-source enthusiasts we can finally start seeing the advantages of the CPU and GPU on the same bus. Oded Gabbay of AMD announced the big HSA kernel patch-set:..

    Is that new A10-7800 APU on the picture - 65W/45W part? Like lower TDP on that one, 512 shaders with 45W sounds cool .

    BTW congrats on HSA driver

      A10-7800 is a 65w TDP part.

        Nice, but don't we still need OpenCL working in Gallium to make full use of it?

          I think that one does not exist A10-7850K is earlier 95W part and now this new A10-7800 (without k) which can be configured as 45W:

            what happen if we choose 45w? underclock the cpu or gpu or both? or only the turbo is affect? i can't see nothing in google about this only curious

              Other languages are being built over HSA as well -- there are a couple of different Java implementations and C++ AMP too :

              You should see work on OpenCL ramping up soon, if not already.

                Not sure, there are also some PRO models (those with B) listed at AMD site which can run even as 35 W TDP . I guess those reduce turbo core frequency or may be disable it, but being optimized not too loose to much performance... who knows .

                    Nice! Let's hope the new driver strategy is getting to market soon aswell. I hope we can expect it before the year's end.
