Is there a way to track VGPR usage using CodeXL? For e.g. can one get feedback from CodeXL about where the VGPRs counts come from?
Please see this thread for more information:
CodeXL 1.4 does not provide this functionality. We're working together with the runtime and compiler teams to improve the visibility of how changes to the high-level source code affect the generated ISA, and highlight resource usage in the ISA code.
Thanks for your reply. In that case, how does CodeXL show the number of VGPRs used by any kernel code?
The AMD OpenCL offline compiler provides statistics about resource usage by the compiled kernel. This is the information that CodeXL presents in the Statistics view.
