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.

[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.
Thanks
Miklos

Just another use-case,
FreeRTOS is using the non-secure SVC. It does not expect that it may be used by somebody else (not RTOS).
Ideally, if TFM will not occupy SVC.

Can you share us your usage details? This could help us on defining the svc number things you mentioned.

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

As a follow-up, mcuboot has removed the pycrypto dependency, so I
will put an update together for TF-M for review:

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.
Thanks,
Antonio

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:

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?

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
I cherry-picked the commit into my build area and confirmed that it behaves properly.

Hi Alan,
The interface call from ' tfm_core_init() ' to 'tfm_spm_hal_set_secure_irq_priority()' is planned to be left there as it is now. If a certain platform implementation doesn't allow interrupt priorities to be set, it can leave the implementation of 'tfm_spm_hal_set_secure_irq_priority()' function empty.
Regards,
Mate

Subject: Re: [TF-M] including platform specific interrupt definitions
Adrian,
Yes, I noticed this.
I guess that means that the handler name will be derived from the 'source' string. Sadly, it appears that the CMSIS convention for naming IRQ numbers is 'PeripheralX_IRQn'. Given your handler naming convention, that means that the handler names I have to put in my platform's vector table must be 'PeripheralX_IRQn_Handler'. I prefer 'PeripheralX_Handler' myself and that is what I've telegraphed to our development team.
I'm thinking we will honor the PSA FF convention that if ONLY the 'source' attribute is provided for an IRQ, your name mangling rule will be followed for generating the ISR function name.
Additionally, we will modify the template such that if a custom attribute of 'handler_name' (or some such) is ALSO provided, we will use our own name mangling rules for generating the ISR function name so that we are free to populate the vector table with whatever function names we want.
Similarly, it appears that support for the 'tfm_irq_priority' attribute will be a platform-specific extension. Does this mean that the logic currently in tfm_core_init() that calls tfm_spm_hal_set_secure_irq_priority() for each interrupt will be removed from the standard code base?

Just as a heads up for future consideration. In the final version of the PSA-FF spec we replaced the `line_num` and `line_name` attributes with a new single attribute called “source”. You can use numbers or string identifiers with it (see change log in Appendix E of PSA-FF 1.0.0).

Hi Alan,
These attributes should be already included in 'test/test_services/tfm_irq_test_service_1' of latest master, you can check the sources.
The alignment is a big task and the patch mentioned in this mail thread is the first one of prototype change. The whole FF 1.0.0 alignment (behaviors change e.g.) would come step by step later on.
And the interrupt priority -- let me check with interrupt designers to know more details. Current from my point of view it is platform defined setting which is out of FF scope.
Thanks.
