Hi Christian,
well, this warning is intentional.
The key point is that your random config results in a very suboptimal
situation where the graphics driver only barely work.
ok
And radeon is pointing that out with this warning. That is totally
expected behavior.
Sure, but I don't think that it should break the build.
well, this doesn't break the build we already have that for years.
What breaks the build now is that warnings are handled as errors.
Can you add a boot-time warning message instead?
Yes, we already have that as well.
And/Or compile out the warning when "warnings = errors"?
That should be doable I think.
Regards,
Christian.
All the best,
John

Christian.

Is anything being done to fix it? I don't see anything in -next or
on dridevel list recently which it could be.
thanks,
