There can always be a fork of the sources kept in TF-M repos to handle the case of needing local modifications for some reason. - k > On Jul 10, 2019, at 3:48 AM, Andrej Butok via TF-M <tf-m(a)lists.trustedfirmware.org> wrote: > > Hi Kevin, > > Only if 100% of the external project source code is used without change. > Even if it is valid now, nobody will give you this guarantee in future. > > Regards, > Andrej > > -----Original Message----- > From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Kevin Townsend via TF-M > Sent: Wednesday, July 10, 2019 10:41 AM > To: Thomas Törnblom via TF-M <tf-m(a)lists.trustedfirmware.org> > Subject: [TF-M] Using git submodules for dependencies? > > Hi, > > I'm currently working on integrating TF-M into Zephyr and getting TF-M working with QEMU.

Using git submodules for dependencies?

by Kevin Townsend

Hi, I'm currently working on integrating TF-M into Zephyr and getting TF-M working with QEMU. Part of that work is simplifying the setup and build process to generate a TF-M secure library. Was the idea of git submodules for dependencies considered and rejected? Using sub-modules would reduce the number of setup steps required, and pair external dependency versions with specific TF-M commits/releases. There may be a valid reason this approach was rejected, but it seems like a sensible option on the surface? Best regards, Kevin Townsend

independent device driver model working along side SPM

by R, Manoj

Hi, Is there a design guideline available for device driver which is working on secure side alongside SPM. I do not want to plug my driver in TF-M due to latency considerations. Basically my plan is to introduce non secure callable veneers for calling the interfaces of the driver which I am introducing. Any thoughts on this will be helpful. Regards Manoj

Changes to PSA headers in TF-M

by Jamie Fox

Hi all, I am proposing a couple of changes to the standard PSA headers in TF-M. The first change is here: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1458/ It renames the standard PSA headers in TF-M from psa_<api>.h to psa/<api>.h. TF-M defined headers are not affected. This change also tweaks a large number of #includes across the TF-M repo to use the new names. Any code maintained outside the TF-M repo that includes PSA headers from TF-M will also need to be changed to use the new names in #includes once this is merged. The benefit of this change is that is brings the names of the headers in TF-M into agreement with the names used in the PSA Firmware Framework. It will also make running the PSA API tests easier, as the step of copying the PSA headers to the standard names is no longer required. The second change is here: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1459/ It adds a copy of the psa/error.h header, which contains new standard error codes intended to be used by the SPM and RoT Services. The "PSA_SUCCESS" and "psa_status_t" definitions are also moved to this header, and it is included by psa/client.h and psa/service.h. This change should have minimal impact on other code -- no code is immediately changed to use the new error codes, but upstreaming the header now allows services to start using the new error codes when needed. Kind regards, Jamie

[RFC] Secure Partition Runtime Library

by Ken Liu (Arm Technology China)

Hi, We are now involving secure partition runtime library into tf-m design. While implementing isolation level 2, some runtime APIs (printf e.g.) calling would cause fault, because it is accessing global variables (The STDIO instance) or need to manipulate hardware (UART). So we shutdown calling to these APIs - it is lucky that the secure service logic does not rely on these functions. This leads to the thinking of runtime APIs implementation - not only C runtime mentioned in PSA FF specification, but also developer APIs for service client. These APIs are definitely necessary and need to work well under all isolation levels. Since we cannot put multiple runtime copies into secure partitions (waste and not supported by single firmware linker design), shared runtime library looks like the only choice. Here we introduce the design of a runtime library for secure partition usage. We aligned the concepts with PSA FF and it does not break the mandatory requirements of isolation, and proposes designs for some dedicated APIs. I know there may be similar runtime implementations somewhere, while I just want to implement the functions quick to make out a solution before other library searching and investigating stage (which may spent quite much time). The key requirements of this runtime library are: - This library is protected as Read-Only + executable by MPU, so all other data will not be included into protected region. This point is very important. - For those session/handle based API set, necessary supporting from tooling or other parts needs to be involved. Please help to review the design document at: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1425 Feel free to add you as reviewers and comment something; and you can reply to this thread, too. Any new thinking is worthy of being discussed. Thanks. -Ken

Experimental IAR support

by Thomas Törnblom

Thank you for merging my cleanup in T398. I have a set of IAR build related files that I would like to push, both new and modified cmake files and startup and linker scripts for the Musca A board. There is still some work needed on the linker scripts to get everything fully functional but I can load and debug the secure and non secure images, and the non-secure image will start and execute the idle thread. I have not tested mcuboot although it appears to build properly. We have chip vendors that are eagerly awaiting our port and I would like to push this as "experimental". Would this be OK? /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: www.iar.com <http://www.iar.com> Twitter: www.twitter.com/iarsystems <http://www.twitter.com/iarsystems>

Re: [TF-M] Feature request

by Gyorgy Szing

Hi Andrej, We shall avoid adding IDE specific workarounds to the code. I see many possible better solutions to this problem: 1. All IDEs are capable to "ignore" files present in the working copy but not part of the build. You could try this feature. 2. Irrelevant files can be deleted from the workspace by using a script. 3. Using a different generator of CMake could allow to generate a project format which your IDE can import. (See https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html) 4. Using CMAKE_EXPORT_COMPILE_CMMANDS will make CMake to generate a json file listing all C files part of the build with the build command needed to compile them. It could be relative simple to write a Python script to create an IDE project or to update an existing one with build settings. (See: https://cmake.org/cmake/help/latest/variable/CMAKE_EXPORT_COMPILE_COMMANDS.…) 5. Long term a generators could be up streamed to CMake to add Support for you IDE. Please contact the IDE vendor with this request. 6. The IDE could be updated to co-operate with "cmake server" to allow integration with cmake based build systems. Again please contact the IDE vendor with this request. /George -----Original Message----- From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Andrej Butok via TF-M Sent: 18 June 2019 08:23 To: Miklos Balint <Miklos.Balint(a)arm.com>; Thomas Törnblom <thomas.tornblom(a)iar.com> Cc: tf-m(a)lists.trustedfirmware.org Subject: 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.

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.

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. We are using IDEs (IAR, MCUx, Keil), so we have to add missing #ifdef to the original TFM source code. Please use #if/#ifdef in TFM, everywhere were it is needed.

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.

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.

Re: [TF-M] [RFC] Move configuration files into specified directory

by Ken Liu (Arm Technology China)

Hi, The patch has been pushed for a while and is going to be merged in one week, please help to review it if you planned but still not have a look: https://review.trustedfirmware.org/c/trusted-firmware-m/+/1234 After this patch get merged, all new configurations created in root directory will be rejected. Please create new configuration files under ./configs directory. The existing fake configuration files under root directory will be removed after CI setting changed. Thanks. -Ken > -----Original Message----- > From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Ken Liu > (Arm Technology China) via TF-M > Sent: Tuesday, June 11, 2019 1:40 PM > To: TF-M(a)lists.trustedfirmware.org > Cc: nd <nd(a)arm.com> > Subject: [TF-M] [RFC] Move configuration files into specified directory > > Hi, > Since the number of configuration files is increasing, let’s move the > configuration files (ConfigXXXX.cmake) into specified directory. > This would reduces the files under root directory and makes the structure more > clearer. > > I have created the issue and patch for it: > https://developer.trustedfirmware.org/T394 > https://review.trustedfirmware.org/c/trusted-firmware-m/+/1234 > > IMPORTANT NOTES: > To be compatible with the existing building configurations, the existing > configuration files have been forwarded into the corresponded configuration > file under ./configs.
