Hello, Attached a small patch that correctly identifies the DLLoff bit for >=GF100. Marked RFC because I haven't seen any GDDR5 samples that *enable* the DLL. I'd like to verify whether the DLL should be reset when enabled. Could increase likelihood of succesfull reclock. Ben: could you do some experiments with this bit to see if GDDR5 needs some DLL re...
