Changes to CI for python dependencies

tfm_ns_interface functions refactoring

by Kevin Peng (Arm Technology China)

Hi, I made some changes to the tfm_ns_interface_ functions. They have common implementations that call os_wrapper_ functions. With these changes, RTOSes only need to implement the OS dependent functions defined in os_wrappers rather than the tfm_ns_interface_ functions. There are several changes with a same topic: https://review.trustedfirmware.org/q/topic:%22refine_ns_interface_functions… Please help on reviewing. Thanks. - Kevin

Non-secure SVC handling

by Miklos Balint

[from thread: RE: Adding a platform specific tfm_svc_number_t] Hi Andrej, Please note that non-secure SVC handling is independent of secure SVC handling - the two are implemented separately in the code base and hardware resources are banked for their execution. The original discussion is about secure SVC handling type and functions, which are unrelated to NS RTOS dependency on (NS) SVC. I'm starting a separate discussion thread for NS SVC occupancy to avoid blurring the lines between the two. Please note that any example code in the TF-M repository on NS SVC handling is for demonstration purposes and not, strictly speaking, part of TF-M core implementation. It shows how a non-secure privileged entity needs to register a client ID to the SPM on task creation, if multiple client IDs are managed by the RTOS. Whether a specific implementation uses SVC or another method for running the corresponding privileged code is out of scope of the design, only one possible option is shown, but this is an RTOS-specific problem. Meaning that in an RTOS where the adaptation layer mustn't use SVC and is relying on some other method, there's no design limitation in TF-M that is in conflict with that - the implementation can be adjusted in line with the RTOS's method of choice, but where the NS RTOS has no such restriction, the adaptation layer can rely on SVC for this feature.

[RFC] Code restructure of core/spm

by Ken Liu (Arm Technology China)

Hi, Several patches for code restructure is coming. Before I post the gerrit items, I want to collect your feedback on this. These changes contain: - Move header files into dedicated directory for easy include, and clean the included headers in sources; - Change some files' name to let them make more sense. - Move SPM related files into 'spm' folder instead of putting them in 'core'. - Move some interface files into 'ns_callable' since they are interfaces. - Remove 'ipc' folder after all files in it are well arranged. I will try to do these patches together so they can be merged together. But before that I want to request for comments about this, feel free to reply in this thread or comment on the task (add yourself if you are missing as subscribers): https://developer.trustedfirmware.org/T426 BR /Ken

Re: [TF-M] Outdated pycrypto dependency in BL2's imgtool.py

Hi Kevin, We are open to scope what would be needed to move to more supported alternatives, for example: https://pypi.org/project/cryptography/ If you have any specific idea, please submit it. As far as I can see now, there is not a specific reason to stick with the old pycrypto module.

Outdated pycrypto dependency in BL2's imgtool.py

by Kevin Townsend

Hi, As part of an effort to enable automatic builds of TF-M in Zephyr, I've been trying to get the TF-M + Zephyr S/NS images building and passing on Zephyr's CI system. The only missing requirements for building TF-M in a clean Zephyr SDK 0.10.1 based environment is the pycrypto module, which is used in the imgtool.py utility, specifically: https://git.trustedfirmware.org/trusted-firmware-m.git/tree/bl2/ext/mcuboot… My concern is that this module is no longer actively maintained (last release was 2013!), and it seems like a poor decision to rely on something that isn't actively maintained when more recent alternative are available. Is there a specific reason to keep this module in the script in favour of something more modern? Best regards, Kevin
