>Environment:
System : OpenBSD 6.9
Details : OpenBSD 6.9-current (DRMDEBUG) #0: Wed Jun 23 18:49:07

[email protected]:/sys/arch/macppc/compile/DRMDEBUG
Architecture: OpenBSD.macppc
Machine : macppc
>Description:
During the boot, i hit the following error message:
radeon: ring test failed (scratch(0x15E4)=0xCAFEDEAD)
This leads to no GPU acceleration. I've built a kernel with DRMDEBUG, but the
below output seems not very interesting. I can still use X11, but need to
disable GLX in xorg.conf because llvmpipe also does not play well, with "LLVM
ERROR: Relocation type not implemented yet!".
I tried to attach appleagp thanks to the XXX hints found in
dev/pci/agp_apple.c. Instead of CP issues, i had IB issues. It lead me to bug
reports saying that PCI mode should be forced, which is the current situation.
RV100 is also impacted [0], but the screen is blank instead.
I tried a drm510 kernel, which does not solve the issue.
>How-To-Repeat:
Run OpenBSD/macppc on an iBook G3 with RV100/RV200 videocards.
>Fix:
None known.
