Re: [TF-A] Does TF-A support to load and run both TEE and SPM_MM?

by Achin Gupta

Hi Heyi, Happy to discuss the detail but the short answer is no. Instead, it is possible to run an MM partition in S-EL0 under the TEE. This work is being done with OP-TEE. From a SW architecture standpoint, it did not seem like a good idea to let EL3 run its "application" i.e. MM SP alongside a TEE which also runs its own applications. It is better to let the TEE own S-EL1 and run all applications in S-EL0 under it.

Does TF-A support to load and run both TEE and SPM_MM?

by Heyi Guo

Hi All, On some platforms there may be requirements to run both TEE and SPM_MM instances, such as providing TEE services on server platforms. Do TF-A support this scenario? If it doesn't, do it make sense to add such support? Thanks, Heyi

Hafnium / TF-A v2.4 first tagged release is available

by Olivier Deprez

Hi All, Following the announcement of the Trusted Firmware-A/Trusted Firmware-A-tests v2.4 release: We are pleased to announce the first tagged release of Hafnium [1] implementing the SPMC according to the FF-A v1.0 specification [2]. As a reminder, Hafnium has been transferred to trustedfirmware.org back in May 2020 to become the reference open source S-EL2 firmware, under an Arm/Google co-maintainership. Contributions are open to partners in trustedfirmware.org The Secure Partition Manager documentation is available at [3] Please also refer to the change log at [4] The companion TF-A test suite permits the validation of FF-A ABIs and NWd/SWd communication by the use of bare-metal S-EL1 secure partitions. Thanks to all who contributed to make it happen. Regards, Olivier.

TF-A Tech Forum Agenda @ Thr 19th November 2020 16:00-1700 GMT

by Joanna Farley

Hi All, The next TF-A Tech Forum is scheduled for Thu 19th November 2020 16:00 – 17:00 (GMT). Please note UK entered Daylight Saving on 25th October when clocks went back one hour to go to GMT from BST. A reoccurring meeting invite has been sent out to the subscribers of this TF-A mailing list. If you don’t have this please let me know. Agenda: * Trace-based Code Coverage Tooling for Firmware Projects * Presented by Basil Eljuse & Saul Romero * Summary * TF-A has adopted a code coverage system to measure the effectiveness of the various runtime testing performed and this is achieved without doing code instrumentation. This presentation is an overview of that approach which has applicability beyond the TF-A project. * Optional TF-A Mailing List Topic Discussions If TF-A contributors have anything they wish to present at any future TF-A tech forum please contact me to have that scheduled. Previous sessions, both recording and presentation material can be found on the trustedfirmware.org TF-A Technical meeting webpage: https://www.trustedfirmware.org/meetings/tf-a-technical-forum/ A scheduling tracking page is also available to help track sessions suggested and being prepared: https://developer.trustedfirmware.org/w/tf_a/tf-a-tech-forum-scheduling/ Final decisions on what will be presented will be shared a few days before the next meeting and shared on the TF-A mailing list. Thanks Joanna
