I seem to have come across a strange bug while doing KVM development. It seems that the final tlbwe in finish_tlb (head_44x.S) is actually leaking RPN bits into the "attribute" word.
When I set a breakpoint there and press enter on the serial console, I see r12=ef600703, which is the physical address of the UART on this chip (440EP), plus the correct permission bits at the bottom. Am I crazy? I'm not really looking to step through that assembly right now... Clearly (current) hardware is just ignoring these errant writes, but it should be fixed. -- Hollis Blanchard IBM Linux Technology Center _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
