CodeXL User Guide· Multiple instance of CodeXL Power Profiler cannot be run simultaneously. If the CodeXL graphic client is conducting a power profile session then no other instance of the graphic client can perform a power profile and the command line tool cannot be run either, until the original profile session ends.
· ICELAND discrete GPU(Topaz-XT, Topaz PRO, Topaz XTL, Topaz LE) series is not support in 2.0 release.
· Please make sure you have latest catalyst driver installed before running power profiler. Newer version of discrete GPU may go to sleep (low power) state frequently if there is no activity in that GPU. In that case, power profiler may emits a warning AMDT_WARN_SMU_DISABLED. Counters may not be accessible during this state. It is advisable to bring discrete GPU to active state by running some openCL or openGL application, then run power profiling on that GPU.
· Process profiling is supported only with command line tool. If PMC (Performance Monitoring Counters) counters are not accessible and unable to calculate the IPC load, then compute unit power is distribute equally to each core. In that case power distribution to each process may not be accurate.
