there are several AMD slides floating taking about GDS on 4850/4870 GPUs, global data store. I am not sure how to access them in the current 1.21 beta release.
Another question is that, from the header files in 1.21 beta, there is another term, global GPR. What is the different from GDS?
BTW, I dumped the properties reported from CAL package on 4850. It said
GDS is not supported and Global GPR is supported. What's wrong with my GPU?
