Meanwhile, I was playing with full reclocking trace, and I attach it here. I kept all (or at least vast majority) of PFB accesses so that you could look what it does to memory timings. It reduces power usage to 15.5W (and blob it about 15.3W). When I replay it, then load nouveau, then fix flag register and powerdown unused DAC, I get 15.8W. If I run full blown desktop, I am getting ~16W while I let the system go idle. Pretty impressive, considering that on stock nouveau, 21W was lower bound for power usage.... -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
