            Bug ID: 96423
           Summary: radeonfb: BAR 0: can't reserve [mem
                    0x98000000-0x9fffffff pref]
           Product: DRI
           Version: XOrg git
          Hardware: PowerPC
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: mathieu.malaterre@gmail.com

On a PowerPC machine, when Open Firmware Frame Buffer is used (OFfb), I
cannot `modprobe radeonfb` (but I can load `radeon`). It currently 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`:

https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/radeon/radeon_drv.c#L353

[...]
        /* Get rid of things like offb */
        ret = radeon_kick_out_firmware_fb(pdev);
        if (ret)
[...]

--- Comment #1 from Alex Deucher <alexdeucher@gmail.com> ---
radeonfb is a different driver than radeon.  Please file a bug at
https://bugzilla.kernel.org/ against
Product: Drivers
Component: Video(Other)

If radeon works, why not use it?
