ACPI support
by YhLu 11 Mar '04

Stefan, It seems that you put some code about acpi in the tree. What's your plan about that? Can I use that together with ACPI support in Kernel to make "shutdown -h now" to be real shutdown the power? Regards YH

And possibly some memory loading requirements. There are one or two other things, power control or irq stuff. And I think there one or two errata. It is nothing huge but it should all be covered in the latest BIOS programmers guide and the revision guide for the K8. And I believe the CG stepping is publicly documented now so anyone who wants to look through things and make certain we are uptodate should be able to do it just by wading through the docs. AMD keeps enhancing things and their processor keeps getting better. We poor BIOS guys just have to keep up. Oh and there is the cpu name string that we could fill in if we felt so inclined. I don't think I have ever gotten that far. I'm busy working on a different port so I don't think I will refresh Opteron code past the C0 stepping any time soon. Anyway it is probably more important to make certain we have the normal Opteron ports working before we get to far into that. I am just trying to flush my queue of outstanding issues before they start suffering from bit rot. A lot of the code I flushed today has been running on Lightning and Orange for a while. I think everything except the cleaned up superio. Eric

OEM looking at LinuxBIOS
by Anthony Winner 11 Mar '04

11 Mar '04

Hello all, I work for a OEM and I'm playing with the idea of using linuxBIOS, I have all of the technical info for the machine short of the actual source code to the Phoenix BIOS we use now as it was done by a contractor before I joined the company. Are there any pointers for a 'from scratch', implementation? Should I start with the old code or start fresh from the new freebios2 tree? For reference, the machine is a Intel PIII with a 82830 Northbridge, a 82801ca Southbridge, TI pci1450 card bus controller, and a pair of SMC SIO chips....

Just an FYI there is some work needed to support the latest K8 steppings mostly they are Athlon64s. And that is the one item I forgot to put on my todo list... Eric

We're going to have some real collisions when you commit. We are using the round() function for clarity, e.g. limit = base + round(resource->size, gran) - 1UL; ron

I wonder if why this work on LANL clusters and not on others is the result of code skew. Lightning nodes with myrinet only seem to have one prefmem region. Yet another reminder that I really need to finish syncing up the code bases. Eric
