Oded Gabbay, HSA Linux Kernel driver maintainer presso AMD, rende noto che sono disponibili i sorgenti delle HSA Runtime Library per i sistemi operativi GNU/Linux, per il momento ottimizzati solo per le APU Kaveri (non si fa riferimento a Carrizo). Red Hat, come già ci ha comunicato Gianni Anguiletti in questa intervista, considera molto interessante il progetto HSA, quindi nel 2015 potremo vedere i primi software Open Source di classe Enterprise pronti a sfruttarlo. Anche SUSE, Debian, Ubuntu e le altre maggiori case impegnate nello sviluppo di S.O. GNU/Linux in ambito Enterprise seguiranno sicuramente l'esempio di Red Hat. Per quanto riguarda il software di classe Consumer, invece, non si hanno tempistiche precise.
Qui di seguito il comunicato di Gabbay:
Hi,
I'm pleased to announce that AMD has published the full code of the HSA
Runtime library.
The code can be found at:
https://github.com/HSAFoundation/HSA-Runtime-Reference-Source
As I stated in the amdkfd v5 cover letter, this release, coupled with the r600
LLVM back-end, provides a complete userspace Open Source stack/solution for
running HSA applications using kernels written in OpenCL C99 on top of amdkfd.
As promised, the git repository also contains an HSA port of the OpenCL
MatrixMultiplication application, which can be used to demonstrate how the
compiler, stack, libhsakmt and, of course, amdkfd work together. Together with
the c file of the application, we have provided the source of the OpenCL kernel
and a binary version of that kernel.
There are complete instructions in the git repo on how to build the HSA RT and
the HSA application from source. In addition, if someone wishes to compile the
OpenCL kernel, there are instructions on how to do it (using the modified r600
LLVM).
If anyone is interested in running the sample HSA application on Kaveri H/W,
please take my latest amdkfd-v6 branch and together with the updated Kaveri
firmware files.
The amdkfd-v6 branch can be found at:
http://cgit.freedesktop.org/~gabbayo/linux/?h=amdkfd-v6
The firmware can be found at :
http://people.freedesktop.org/~gabbayo/firmware/ucode.tar.gz
Finally, I would like to thank the HSA RT team, the Finalizer team, the Open
Source graphics team and last but not least, John Bridgman, for helping with
this release.
