Hi, The company i worked for has designed a card that uses the AMD Turion. It uses the PHOENIX Bios. I am trying to port linuxbios to it. But among other issues, one hardware engineer told me to make sure that linuxbios was using the latest AGESA code from AMD (from what i understand that code changes the CPU processor state, frequency,...)as it seems we had trouble in the past getting the right BIOS with the latest AGESA code.
How does linuxbios manage to do the same thing as the agesa code (and at what agesa version)? If so what is the file location that handles it?
Thanks a lot, -jf simon

another acronum I don't understand. What is AGESA?

Sorry about that. It stands for AMD Generic & Encapsulated Software Architecture. From : http://www.ami.com/news/pressshow.cfm?PrID=187
"...The AMD Generic Encapsulated Software Architecture (AGESA) is a library of validated processor procedures designed to aid customers with quick adoption of AMD technology into their products. AMI’s drop-in support of AGESA allows minimal time-to-market for APTIO® customers to integrate AMD Processor Solutions into their products. AMI’s integration in APTIO® indicates that AGESA™ code is versatile enough that it can be dropped in totally new architecture (UEFI) with minimal build changes...."
I was told that this agesa code was responsible at power-up, for changing the CPU "P-state" from Min P-state, (minimum frequency, reduced power consumption) to the maximum performance max P-state. Could you plse point me in the linuxbios code, where this achieved?
Thanks a lot -jf simon

looks like another nice piece of software to support binary BIOSes? Is the source available?

No. AMD told us they give it to bios vendors only. -jf simon
