Description Mathieu Malaterre 2016-06-07 12:25:25 UTC
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`:


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

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?
