Set PSA_2_0_0 as default attest profile and removal of PSA_IOT_PROFILE_1

by Tamas Ban

Hi, We are going to set the PSA_2_0_0 profile as the default for the initial attestation service. This will impact which claims are included in the token and their key values. More details are here: https://www.ietf.org/archive/id/draft-tschofenig-rats-psa-token-24.html Changes on review: https://review.trustedfirmware.org/q/topic:%22attest_profile_update%22 As a follow-up action, the PSA_IOT_PROFILE_1 is being deprecated. We are planning to remove it from the code base as well. To figure out the timing of this we would like to collect some data: * If you are using the PSA_IOT_PROFILE_1 please let us know what would be a feasible time for you to switch over the PSA_2_0_0 profile. Thanks! Best regards, Tamas Ban

PSA Certification for TF-M

by Zhang, Hao

Hi TF-M committee, I have a question regarding PSA certification. Am I understanding correctly that if a platform wants to be ported to TF-M and the product wants to pass PSA certified, the TF-M version needs to come from a certain LTS tag release (e.g. TF-M v2.1.0<https://github.com/TrustedFirmware-M/trusted-firmware-m/tree/TF-Mv2.1.0> with commit 0c4c99b<https://github.com/TrustedFirmware-M/trusted-firmware-m/commit/0c4c99ba33b3…> that was pushed 5 months ago). However, Zephyr v3.7.0 is using TF-M version<https://github.com/zephyrproject-rtos/zephyr/blob/v3.7.0/west.yml#L330C17-L…> that is updated after TF-M v2.1.0. Does that means efforts need to be done to manually modify west.yml in Zephyr to roll back to the tag release of v2.1.0 for PSA certification? Thank you very much, Best, [https://opengraph.githubassets.com/f92ee5eaaedaf25d7ae17b5e8fc073a1573b0f31…]<https://github.com/zephyrproject-rtos/zephyr/blob/v3.7.0/west.yml#L330C17-L…> zephyr/west.yml at v3.7.0 · zephyrproject-rtos/zephyr<https://github.com/zephyrproject-rtos/zephyr/blob/v3.7.0/west.yml#L330C17-L…> Primary Git Repository for the Zephyr Project.

QEMU usage

by Matthew Dalzell

Hi everyone, It has come to our attention that QEMU is no longer able to run the regression tests in a timely manner, and before we go ahead and outright disable them, we would like to know if anyone is using QEMU for their platform testing. If so, please reply to this message and we can have further discussion on the point. Thanks, Matt
