An open-source TCG Software Stack implementation, created and released by IBM: http://sourceforge.net/projects/trousers/

We'll want to use trouser for any tpm support. We should get the system ready by getting trousers in the image and the test suite working with the tpm emulator so that it'll be easy to cut over to a real TPM.

Set Area-??? to area of the system under which this task belongs. Set Effort-??? to estimated number of eng-weeks to implement the task. Assign an Owner and Mstone if known.

Making this a requirement for R6, but it'd be preferred in R5. We may need to sort out what we want to bring up and how we want to support the tpm emulator at build time (e.g., set_use_tpm_emulator.sh prior to a build if that image will be in a non-tpm- available environment)

I was advised to add the kernel modules and trousers to the chromeos image, and tpm- emulator to chromeos-dev. Not sure this is the best solution though, because we eventually rely on the emulator if there is no hardware TPM. That is, basic stuff will not work without the emulator.

OK. There is a perfect solution with the new build system. We can import the tpm- emulator on a per-board basis using overlays. Thus it can be included in the source and images only for boards that don't have a TPM.

Search for "overlay" in src/chromium.org. Right now we have overlay-st1q.git and overlay-x86-generic.git.

What we really need is to add it by default, and then exclude it from configurations in which the TPM is available. I am not sure how to do this---I will investigate.

Bulk edit for issues with old Mstone. Next step is triage using up to date info.
