[Mesa-dev] radeonfb: BAR 0: can't reserve [mem 0x98000000-0x9fffffff pref]

[Mathieu Malaterre]

Hi,

Before reporting a possible invalid bug report. Does anyone knows why
radeaonfb is not configured the same way radeon is ? For instance on a
PowerPC machine, when Open Firmware Frame Buffer is used (OFfb), I
cannot `modprobe radeonfb` (but I can load `radeon`). It fails with:

[   96.551486] radeonfb 0000:00:10.0: enabling device (0006 -> 0007)
[   96.551526] radeonfb 0000:00:10.0: BAR 0: can't reserve [mem
0x98000000-0x9fffffff pref]
[   96.551531] radeonfb (0000:00:10.0): cannot request region 0.
[   96.551545] radeonfb: probe of 0000:00:10.0 failed with error -16

It seems (to me) that it should be possible to add something like this
to `radeonfb`:

Is the above correct ?
