Service vs Partition wording in manifest files

by Bohdan.Hunko＠infineon.com

Hi everyone, From what I see manifest lists (e.g. tools/tfm_manifest_list.yaml) describe partitions, but "name" field there (which is a description of the partition) uses "Service" word, for example: "name": "Protected Storage Service", Shouldn't this be "name": "Protected Storage Partition" ? Why do TFM uses Service when describing the Partition?

Request about local test with IAR compiler

by Jianliang Shen

Hi, I made a patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/16106> to change CMSIS-RTOS RTX library attribute for ARMv8-M Mainline platforms in TF-M, the reference is CMSIS-RTOS2<https://www.keil.com/pack/doc/CMSIS/RTOS2/html/pDirectory_Files.html#libFil…>. As CI doesn't cover IAR compiler, I'm very grateful if someone who is convenient can help me build and run it with IAR toolchain locally. Best Regards Jianliang Shen

Proposal for coding standard update: Increase chars per line 80-> 128.

by Anton Komlev

Hi, TF-M coding standard<https://tf-m-user-guide.trustedfirmware.org/contributing/coding_guide.html> mandates up to 80 characters per line. This looks a bit too restrictive nowadays with no punch cards or text terminals. I propose to increase this limit to 120 or 140 characters. Personally like 128. Are there any thoughts or objections against it? Thanks, Anton

Example Partition Updates

by Kevin Peng

Hi all, Please be noted that the TF-M example Secure Partition has been moved from the tf-m-tools repo to the tf-m-extras<https://git.trustedfirmware.org/TF-M/tf-m-extras.git/tree/examples/example_…> repo. It has also been aligned with the latest TF-M. The documentations are improved as well. It could be a good reference for Secure Partition developer starters. Best Regards, Kevin

TF-M CI build failures in master

[RFC]Decoupling manifest tool with build system

by Kevin Peng

[Thread res-used, title renamed] Hi all, This is now happening - fully support non-CMake use of the manifest tool. Here is the patch: https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/15756 With this patch, the manifest tool takes build configurations from a config header file instead of replying on the build system. Please check the details in the patch. Any comments are welcome.

I'm asking because I'm working to support configurable stack_size for Secure Partitions<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.tr…>. In the patch the support of environment variables in manifest lists is removed<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.tr…>. Because I have to call the CMake command configure_file to replace the stack_size symbols (CMake variables<https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Freview.tr…> surrounded with "@") with their values. While configure_file does not recognize environment variables. If you do have environment variables in manifest list, there is an alternative: Replace the env. variables with CMake variables surrounded with "@" and set the value of the CMake variables in either config files or command line inputs.

Intended use of psa_reset_key_attributes()

by S Krishnan, Archanaa

Hi, What was the intended usage of psa_reset_key_attribute(*attributes) which requires a PSA call from non-secure side to reset the client attributes? I am curious because the attributes to be reset comes from the non-secure memory, not directly associated with ITS/PS. The current IPC setup performs a PSA call to tfm_crypto_rest_key_attributes()(https://git.trustedfirmware.org/TF-M/trust… This function creates a copy of client key attribute in a secure key attribute structure. The secure key attribute is reset (set to 0) and then copied back to the client key attribute before returning to non-secure code. At first glance, this seems like a roundabout way to zeorise client side attributes. Regards, Archanaa
