> you yourself do not know if an HD5850 is supported by SVP 4 Linux?
This's not a question of "<some video card> is supported by SVP", but "does <some video card> supports OpenCL using given drivers".
HD5850 DO have all "hardware features" required for SVP to work.
SVP wants a "FULL_PROFILE" GPU OpenCL device supporting "cl_khr_byte_addressable_store" extension, that's all.
