I saw a feature enhancement request go in about supporting the TCG TPM chip in LinuxBIOS. We're interested in helping that effort. Is there anyone leading the charge? Or, by virtue of mentioning it, do I become the defacto lead ;-) ?
I think so, hehe. :)
Are there any thoughts as to how to best measure the LinuxBIOS and FILO portions and extend them into the PCRs?
Seems this is covered by the TCG PC Specific Implementation Specification.
--8<-- TCG PC spec p6 This document serves as implementation reference document for the 32-bit PC architecture. Specifically, this document defines:
· Usage of PCR registers in the Pre-Boot state through the transition to Post-Boot state.
· How the BIOS, or a component thereof, functions as the Core Root of Trust for Measurement (CRTM).
· Programmatic Interfaces to the BIOS as it performs the functions of the TCG Subsystem (TSS and access to the TPM)
· Behavior entering, during, and exiting power and initialization states.
· Guidelines for Option ROMS. -->8--
