Secure Partition interrupt signal processing

by Andersson, Joakim

Hi. I've been working on making an example on how an application can use the secure interrupts in a secure partition in TF-M. During this I've encountered an issue where the secure partition will not be scheduled to process the secure interrupt signal in certain conditions. I've compared it to the current SLIH and FLIH test cases to my observed behaviour and I could see that they did not have this problem. I've created a test-case that triggers the problem [0]. In the mailing list I can see that this was actually discussed recently [1] The summary is that secure partitions will not be scheduled to process a secure interrupt signal when the interrupt is interrupting the NSPE. I could not find that this was documented anyway, but maybe I have overlooked. In any case I find this behaviour very unexpected and I would like to know if this is indeed a design decision and the behaviour has to be this way? If I wanted to do some processing in the secure partition context it would now mean that I have to get the NSPE to trigger this through a secure partition call. This seems like a limitation to me . I'd like to know what would be the issue with scheduling the partition once it now has the signal asserted. I've done a quick test with scheduling the partition at this point with [2] and this now works as I expect it to. I'd be happy to follow up with submitting a change to schedule the partition as done in [2] if that is an acceptable solution.

MCUboot upgraded to v1.9.0 in TF-M

by Sherry Zhang

Hi, Just a reminder that the MCUboot version has been upgraded to v1.9.0<https://github.com/mcu-tools/mcuboot/releases/tag/v1.9.0> in TF-M. If you are using the local MCUboot repo, then you need to update it to that version to avoid build error. Regards, Sherry Zhang

TF-M release v1.6,0 date change to April 28

by Anton Komlev

Hello, TF-M release v1.6.0 will be shifted from April 15 to April 28. The main reason is Easter holiday and expected lack of availability from community and platform owners around that date. Feature freeze will be moved to April 6th when the release branch will be created. Please update your plans accordingly. Please let me know if this change make difficulty for you and better date is possible. Thanks, Anton

Simplify TFM_PLATFORM in build system

by Jianliang Shen

Hi all, I want to simplify the flag TFM_PLATFORM in build system. TF-M now already supports two different ways to choose specific platform, for example AN521: - Absolute path: '<tf-m path>/platform/ext/target/arm/mps2/an521' - Relative path: 'arm/mps2/an21' Recently I have uploaded a [tf-m patch]<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/14260> to support platform name: - Platform name: 'an521' I think it will be more convenient for developers to use: - Users don't need to remember and type the absolute or relative path, only target platform name is enough. - If the structure of certain platform is changed, the default build command of TFM_PLATFORM is same. I'd be very grateful if you can give any suggestion or enhancement for me. Thanks. Best Regards Jianliang Shen

Dear All, I view the tf-m source code for the first time, and many of the code details can not be make clear. So .., where may I find the design documents of spm, for example: trusted-firmware-m-TF-Mv1.5.0\secure_fw\spm\cmsis_func and cmsis_psa software modules.

TF-M covertly results and configs to align our coverity environment to TF-M project CI

by Kostiantyn.Tkachov＠infineon.com

Hi colleagues! Could we get a list of MISRA/CERT-C violations that were found by tf-m Coverity CI, as example from https://ci.trustedfirmware.org/job/tf-m-coverity/lastSuccessfulBuild/ Also (if it possible), could you provide Coverity configs to help align this tool setup on our side to CI and to check all changes before any pool requests? Best regards, Kostiantyn Tkachov Cypress Semiconductor Ukraine Firmware Security
