dmesg with nouveau.debug=debug drm.debug=0xe

Hi,
adding this patch on top of linux-3.19 or tip of
http://cgit.freedesktop.org/~darktama/nouveau

is enough to get a GM206 / GTX 960 to get 'modprove nouveau' to work and
getting output on a VGA monitor attached to the DVI-I port.

However trying the same with a HDMI monitor attached to the hdmi port does not
work.

Attached is dmesg output with extra debugging enabled + a 2nd file with debug
level=trace enabled.

I have also sent an mmiotrace of that hdmi use-case by mail.
