Sorry about that. It stands for AMD Generic & Encapsulated Software 
Architecture. From :

"...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
