Greetings,
I'm wondering if R9 380 GPUs are supposed to offer support for SVM atomic operations and fine grained systems.
My current setup is: Intel i7 3770K + AMD R9 380, Windows 8.1 Pro 64 bit and AMD Catalyst 5.11 beta. I've tried using Catalyst 15.7.1 and 15.10 before this.
Some hopefully relevant fragments of clInfo output:

Preferred local atomic alignment: 0
So SVM atomics seems to be unsupported but this AMD support page mentions:
Highlights of AMD OpenCL 2.0 Driver
Is this a genuine limitation of the chip or an issue with my setup?
Solved! Go to Solution.
At present, SVM Atomics is supported only on Linux 64-bit OS.
Hi Alex, I have whitelisted you and moved your question to the OpenCL forum. You can now post in any of the Developer forums.

Thank you for your help.
I'll get Ubuntu 14.04 x64 set up on my machine.
Currently, as I know, SVM atomics only work on OpenCL 2.0 compatible APUs like Kaveri and Carrizo.

So, is the Linux 64x OS invalid?
No. As per OS, it works on Linux 64bit only.

Right.
