Hi Pierre,
I have applied/changed these lines on
driver/gpu/drm/nouveau/core/subdev/bar/nv50.c:
- line 233: int ret, i;
- line 351: for(i = 0; i < 8; i++)
- line 352: nv_wr32(priv, 0x001900 + (i * 4), 0x00000000);
Booting with both adapters enabled (9600 is the boot adapter), EFI-stub and
EFIFB, loading nouveau without acceleration:leads to scrambled screen. The
resolution is native 1440x900.
Booting with both adapters enabled (9600 is the boot adapter) EFI-stub and
EFIFB, loading nouveau with acceleration, screen/adapter is frozen. System
seems to "hang"/lag.
I am now trying the setup without EFIFB. Report back as I have tested it.
BR.
PS: Do you have a MacBook Pro 5,1 15.4"?</pre>
