Hi, On radeon hardware (I have an evergreen based board): Must stopping/resuming the DCE to access the memory controller be done with the EnableCRTCMemReq atombios table? (from DCE3 in dpm code). Because, in evergreen.c, evergreen_mc_stop and evergreen_mc_resume functions do not make use of that table (register direct access). regards, -- Sylvain
