TF-A Technical Forum Session Agenda for Today

by Joanna Farley

I understand some people may not have seen the calendar invite for today’s Tech Forum session. It is in the archives but formatting has been lost so just confirming the agenda in plain email to the list. Joanna Agenda for Session on 10th March 2022 * Introduction to Arm DRTM specification and its support in TF-A * Stuart Yoder/Lucian Pau-Trifu will go through basic of Arm's DRTM specification, beta specification publicly released https://developer.arm.com/documentation/den0113/latest%C2%A0Manish * Pandey/Manish Badarkhe will go through implementation details and planned delivery in TF-A codebase. Details: * Dynamic Root of Trust for Measurement (DRTM) for Armv8-A is based on concepts from the TCG D-RTM Architecture. DRTM begins a new chain of trust by measuring and executing a protected payload which is in contrast to Static RTM(measured boot) where measurements are done at boot time. * Implementation of DRTM services in BL31 and various platform hooks required. Also, talk about initial support on FVP platform and limitations. We run an open technical forum call for anyone to participate and it is not restricted to Trusted Firmware project members. It will operate under the guidance of the TF TSC. Feel free to forward this invite to colleagues. Invites are via the TF-A mailing list and also published on the Trusted Firmware website.

[MPAM] Removing initialization of MPAM EL2 registers when EL2 is used

by Zelalem Aweke

Hi all, The small patch below [1] removes initialization of MPAM EL2 registers when EL2 is used, with the assumption that if an EL2 software exists it should perform the necessary initializations. Please take a look at the patch and let me know if this change affects any downstream projects. Thanks! Zelalem [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/13805/7

Re: please fix incomplete distclean Makefile target

by Nicolas Boulenguez

Hello. This threads originates in a trivial fix for the 'clean' Makefile target. All contributions, even cosmetic and/or from the outside world, must follow the same formal process. Apparently, the process fails for external contributors. The discussion is visible there: https://lists.trustedfirmware.org/archives/list/tf-a@lists.trustedfirmware.… At this moment, there were more people involved in the discussion than letters affected by the patch, so I was invited to switch to a private mail exchange. I was asked to describe the error messages, did so, and was forgotten ever since. Almost a year has passed, the patch is neither refused nor applied. The connection error still prevents some/all external contributions. The only effect of my request so far is that I have been obliged to create accounts on github and your gerrit instance. Is there hope for a more satisfying conclusion?
