Public bug reported:
Hi, I'm trying to find out the best radeon setup for PowerPC in quantal
and need some advice! The PowerPC kernel is currently setup with KMS
enabled, BUT the legacy framebuffer radeonfb is still built in.
Although this is obviously not an ideal setup it seemed to work okay as
a default setup up until August when UMS was dropped in quantal. I'll
attach a log from my 12.04 install so you can see what used to happen.
Despite the message "[KMS] drm report modesetting isn't supported" the
radeon driver continues to load in 12.04 although drm/dri is non-
functioning (because of the presence of radeonfb).
Now in quantal the radeon driver unloads pretty much immediatly after
the "[KMS] drm report modesetting isn't supported" message. The fbdev
driver takes over in 8 bit pseudo colour which causes all sorts of
problems (bug 1046951).
Is it possible to have KMS without drm?
DRM still causes a lot of freezing problems with radeon KMS on PowerPC
and this is one of the reasons radeonfb is still included in 12.04.
Radeonfb is also needed for suspend. Is there a way to have radeonfb
and KMS working together (without drm) which seemed to be the case in
12.04?
If not then radeonfb should (IMHO) be removed from being built into the
PowerPC kernel, but I currently would hit a new bug with that (bug
1058641).
Thanks
