meta-measured is a collection of recipes and configurations that enable software measurement in Linux distros based on OE. Currently this includes the open source TCG TSS, related TPM tools, and tools enabling the use of Intels TXT. Reference images are also provided as a reference for the use of these tools in minimal builds. My goals for this layer include: 1) extending the measurement scheme to arbitrary software components (not just boot modules & fs images) at boot and runtime 2) enabling measured launch for arbitrary system images 3) supporting non-Intel platforms with hardware support for boot time measurements and the TPM.
