Just upgraded to SDK 3.0. Uninstalled sdk-2.9.1 and reinstalled catalyst 15.9. Upgrade broke a few things, unrelated to ocl, that I got to fix. clinfo reports:
Platform Version: OpenCL 2.0 AMD-APP (1800.11)
Device OpenCL C version: OpenCL C 1.2 (GPU)
Device OpenCL C version: OpenCL C 1.2 (CPU)
GPU is my Saphire Radeon R9 270. Fairly recent card. Isn't it ocl 2.0 compliant?
CPU is AMD FX(tm)-8320 Eight-Core Process. What about this?
Good news, driver version was raised from 1445 -> 1800!
