I've got a patch that matches DRAMCtrl to the new DRAMPower API which I'm working on merging with this ext/* patch to make a single commit. Expect a post in a couple days. Not played around with bank-wise refresh yet. By default it is disabled. The main issue now resloved is that intermediate statsdump in gem5 will now use window energy calculations from DRAMPower to give correct energy deltas over a statsdump period (previously the dumped stats were cumulative). - Radhika ----------------------------------------------------------- This is an automatically generated e-mail.
