Hey,

I am working on my ms thesis regarding GPGPU computing with OpenCL. I am using Radeon HD 4870 as my compute device, but unfortunately found some problems with OpenCL compatibility:

- no local memory support -> using global memory to emulate local
(CL_DEVICE_LOCAL_MEM_TYPE: Global)

- no texture support
(CL_DEVICE_IMAGE_SUPPORT: NO)

I know that those problems were mentioned some time ago on forum, but are there any plans on improving OpenCL support on RV770 (R7xx) chipsets in the nearest future?
