Hi, I am unsure if this is the right place to ask, but it seems relevant. I am trying to use an AMD E8860 (SI) board connected to an E6500 PowerPC board (T2080RDB from NXP). The T2080RDB does not use a BIOS, and uses u-boot to bootstrap Linux. I have the E8860 connected to a PCIe x4 slot with an adapter. The kernel is a 4.1, with DRM included in the kernel and the radeon as a module. The radeon driver detects the card, notices the BIOS hasn't posted and starts things up. After that, the ring tests get run, and fails on the ring 0 test, disabling acceleration. The graphics card is (or seems to be) working apart from that, the driver starts up and sees the connectors on the board. When I compare dmesg on an x86 machine and the PPC machine, I see that the x86 machine loads a lot more firmware from the kernel (probably the acceleration parts?). My question is, what do I need to do to correctly initialize the E8860 board on my powerpc machine? Is there some documentation you can point me to, or someone to ask?
