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)
[...]
