Maybe it's time to remove all non-32bit access to fb.
I expect it is not a very hard work for now ;-).
I seriously doubt that's the problem, because:
- 32bit powerpc doesn't really do 64bit accesses ( unlike sparc for
example ) and altivec is disabled for kernel code ( since gcc started
using altivec for optimized, inlined memcpy )
- at least one of the putchar_aa() methods used memcpy() in order to
speed things up by rendering scanlines into cached memory and then
quickly copying them into slow & uncached video memory, which worked
just fine everywhere I tried ( that is, mips, powerpc, sparc, sparc64
and arm )
Thank you for your suggestive comments!
I probably found the cause of failure; new rasops allocates buffer and
stamp dynamically via kmem_alloc. This may not work in early stages
during boot.
I removed dynamical allocations. Could you please test the attached patch?
PS
I ordered Mac Mini G4, although serial console is hopeless...
They're nice little machines which usually don't cause much trouble.
Opening them is quite painful though.
Yeah, I look to forward to playing with it :-).
Thanks,
rin
