Hi Joanand,

Shouldn't the patch for driver/gpu/drm/nouveau/core/subdev/bar/nv50.c rather be
+ line 233: int ret, i;
+ line 351: for(i = 0; i < 8; i++)
+ line 352: nv_wr32(priv, 0x001900 + (i * 4), 0x00000000);
By the way, on top of which commit/kernel are you applying the patch?

Yeah, if you try with acceleration you end up with bug 27501
(https://bugs.freedesktop.org/show_bug.cgi?id=27501).

EFIFB should not be the problem: it is removed by nouveau at some point, to be
replaced by nouveaufb, which seems to be not rightly configured (or the
accesses to it), bringing screen corruption.

I have a 5,3 (iirc) MacBook Pro (mid 2009) 15.6", with the same graphic cards,
resolution is also 1440x900.

Pierre
