1) Why device fission not supported on HD69xx GPUs ? Is it hardware limitation or current SDK limitation? I read that this GPU could be able to run simultaneously 2 different CAL kernels at least... is it wrong info?

2) what is cl_amd_offline_devices extension ? It mentioned in APP SDK manual but no description given.

3) What value in cl_device_board_name_amd query? In what it differs from common CL_DEVICE_NAME query ?

I could be wrong on this, but I take the cl_amd_offline_devices extension to mean it allows you to compile (or generate a binary, I'm not sure, I haven't specifically looked into it) for devices you don't have in your system.

no GPU currently support device fission.
