Hi All, Not sure if everyone knows that there is an initial deployment of TF-M CI (Continuous Integration) system. It tests every patch that gets submitted in TF-M gerrit. Read about the CI system and find the relevant links in this blog - https://www.trustedfirmware.org/blog/trusted-firmware-open-ci-update/ Thanks, Shebu

Please help review the patches of architecture abstraction in TF-M

by David Hu (Arm Technology China)

Hi all, Could you please review the following patches to abstract architecture specific code? https://review.trustedfirmware.org/c/trusted-firmware-m/+/1157/<https://review.trustedfirmware.org/c/trusted-firmware-m/+/1157> https://review.trustedfirmware.org/c/trusted-firmware-m/+/1158 https://review.trustedfirmware.org/c/trusted-firmware-m/+/1390/ https://review.trustedfirmware.org/c/trusted-firmware-m/+/1251/ https://review.trustedfirmware.org/c/trusted-firmware-m/+/1252/ The above patches abstract architecture specific code to decouple TF-M core to specific architecture details. It can help enable TF-M running on diverse Arm M-profile architectures. Other Arm M-profile architecture implementation will be added later. Suggestions are welcome. Thank you. Best regards, Hu Ziji

Align manifest to PSA FF

by Edison Ai (Arm Technology China)

Hi, I had create patches related to manifest. There are two topics for it: * Align manifest to PSA FF: https://review.trustedfirmware.org/#/q/topic:Align_manifest_to_PSA_FF+(stat… * Generate SID and signal header files according to manifest: https://review.trustedfirmware.org/#/q/topic:generate_SID_signal_header_fil… I had added some reviewers to help to review them. Please feel free to give any comment even you are not in reviewer list(Sorry maybe skip someone by mistake). There are some important patches I think and please pay your attention to them: * Remove "tfm_symbol" from manifest: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1243/ * Change the value of SID: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1246/ * Rename the manifest file: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1247/ * Generate manifest file name header file: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1354/ * Assign signal value to SPM: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1356/ * Generate service ID header file: https://review.trustedfirmware.org/#/c/trusted-firmware-m/+/1353/ Thanks, Edison

Re: [TF-M] T398: Initial support for IAR Embedded Workbench for Arm tool chain

by Christian Daudt

If the objective of assigning it to TEST_PASSED before the test is that it becomes the default final answer (i.e. unless it gets reassigned to TEST_FAILED the final result remains this assignment) then it should absolutely be set to TEST_PASSED at startup. thanks, Christian. ________________________________ From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> on behalf of Jamie Fox via TF-M <tf-m(a)lists.trustedfirmware.org> Sent: Wednesday, June 19, 2019 6:00 AM To: Thomas Törnblom; tf-m(a)lists.trustedfirmware.org Cc: nd Subject: Re: [TF-M] T398: Initial support for IAR Embedded Workbench for Arm tool chain Hi Thomas, Personally I would avoid the type cast too.

Hi Andrej, As I said, that workaround only works for specified case. Debugging these failed cases with this patch applied will lead you into heavy core debugging. We need to find out the root cause, why the assert is triggered? There is no reason that all partitions go into block state, unless there are some improper modification in core or secure partitions. Please check your modification in SST partition, try to print something in your SST thread, to see why the thread keeps in block state. If a client calls psa_connect/psa_all, SPM would activate the partition into running state with function tfm_spm_send_event(). The correct call routine should be (psa_call has the similar routine): tfm_sst_test_2001->psa_connect->...->SVC_Handler->tfm_svcall_psa_connect->tfm_spm_send_event->....-> (your partition thread). Please remove the workaround patch, and try to debug to see if the call routine is correct.

Re: [TF-M] Feature request

Hi Miklos, One more feature request: 3) Using separate files in TFM without #ifdef is causing issues for IDE projects, and requires creation of separate projects/targets (with different file set) per each feature combination.

For issue #1 it makes very much sense to have a shared header file for all components that rely on these definitions. I don't recall any reason why that should not be possible, it's simply something that hasn't been done due to limited bandwidth for such clean-up of the code. For issue #2 we have had some internal discussions on the best way to handle compiler dependencies, and the suggestion I liked the most is similar to your suggestion below, but instead of having a single header file, having a compiler folder with each supported toolchain as a separate sub-folder, each defining their own version of tfm_compiler.h to provide the definitions required by TF-M. The compiler-specific cmake file can then simply point to the appropriate location for the compiler-specific inclusion, avoiding compiler-specific ifdef:s. Let me know your thoughts on this approach Thanks and kindest regards Miklos -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Thomas Törnblom via TF-M Sent: 13 June 2019 16:11 To: tf-m(a)lists.trustedfirmware.org Subject: [TF-M] Feature request While working on porting TF-M to the IAR toolchain, I've run into a couple of issues I'd like to discuss. 1) The duplicated REGION/REGION_NAME/REGION_DECLARE macros. Why are these not defined in an include file instead of being defined in eight different c files? I see that they are also defined in spm_db.h, but that is only included in spm related files. 2) I suggest adding a toolchain related include file that should be included in every source file that is part of TF-M. This could be something similar to cmsis_compiler.h, where a toolchain vendor could add stuff that only relates to a specific toolchain. In our case that could include things like: --- #ifdef __ICCARM__ #define $$ZI$$Limit $$Limit #define $$ZI$$Base $$Base #define Image$$ #endif --- Ideas? /Thomas -- *Thomas Törnblom*, /Product Engineer/ IAR Systems AB Box 23051, Strandbodgatan 1 SE-750 23 Uppsala, SWEDEN Mobile: +46 76 180 17 80 Fax: +46 18 16 78 01 E-mail: thomas.tornblom(a)iar.com <mailto:thomas.tornblom@iar.com> Website: https://eur01.safelinks.protection.outlook.com/?url=www.iar.com&data=02… <https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.iar.co…> Twitter: https://eur01.safelinks.protection.outlook.com/?url=www.twitter.com%2Fiarsy… <https://eur01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.twitte…> -- TF-M mailing list TF-M(a)lists.trustedfirmware.org https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.tru… -- TF-M mailing list TF-M(a)lists.trustedfirmware.org https://eur01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.tru…

Re: [TF-M] TF-M Cooperative Scheduler Design - Scheduling Rules

by Ken Liu (Arm Technology China)

Hi Ashu, The proposal is good and covers most of the cases while a NS and S communication channel is available. And I think below part is going to be considerate before we create design docs to follow this rules: - Leave the NSPE SPM_IDLE case handling as implementation defined instead of involving IRQ to bring more complexity. NSPE could just yield but SPE needs to support a bit asynchronization -- that is not a big fair compare to IRQ communication. - The rules rely on the NSPE/SPE communication channel but for if NSPE has no use/misuse this channel SPE should detect the problem and panic NSPE, this is also can to be implemented. Most of the interrupt priority related rules can be done with hardware setting. The priority of secure partition with IRQ needs to be considerate while partitions designing since in IPC model scheduler decides who should go based on partition priority. Let's see if we can find more cases while implementing.
