Bug#826629: [powerpc] fb-modules package : add radeon driver
Package: src:linux
Version: 4.5.5-1
This is an attempt to resolve the symptoms from #825840 (1). As
explain in this bug report, debian-installer is trying to use radeonfb
on PowerPC. However two things happen:
1. At startup Framebuffer is setup by Open Firmware (OFfb)
2. radeonfb currently does not support 'unloading' existing /dev/fb0
While it would make sense for radeonfb to take over Open Firmware, it
is currently not implemented (2). So an alternate solution would be to
use the 'radeon' driver instead.
I have been reading #782058 and #748398, and if I understand correctly
debian-installer does not *explicitly* load 'radeonfb', instead this
is done by `fb-modules-4.5.0-2-powerpc-di`. In which case I'd like to
request that `radeon` be also added to the list of module for PowerPC.
I am not clear if this will be enough but at least this could be a
step forward. Meanwhile I'll continue working on OFfb to get a
non-inverted display (this is a different issue).
