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

It doesn't matter. They both do the same thing.
