Question about RME-DA in TF-A/TF-RMM/FVP

by Chenxu Wang

Hi all, I find that Arm has considered "device for realms" and purposed RME-DA since last year. This is not only a concept but also includes some SMMU hardware extensions (e.g., Realm Page MMIO and DPT). Unfortunately, I only find few contents related to RME-DA in the latest FVP user guide, and nothing in TF-A/TF-RMM. Thus, can I ask 1. Does current FVP simulate the RME-DA? 2. Will TF-A/TF-RMM supports RME-DA recently? Sincerely, WANG Chenxu

Compatibility support for SPM_MM and SPMD

by baopeng (A)

Hi Olivier Deprez, We use the SPM_MM framework mainly for read/write control of security variables. We do not want to modify the original application code at this time. At the same time we want to add support for the new SPMD framework based code. ________________________________ Hi Baopeng, By "code based on the SPM_MM framework" I assume you refer to a secure service running in a S-EL0 partition based on the MM protocol? If you can share this information, what kind of service is this implementing? RAS handling, secure variables, TPM back end, other? What kind of interface is needed to access the service? asynchronous with interrupts? synchronous with SMC from normal world? Another question is why do you need to collocate the SPMD if the MM implementation is already achieving the scenarios you need? Ideally you'd want to migrate this service to run on top of: * the EL3 FF-A SPMC https://trustedfirmware-a.readthedocs.io/en/latest/components/el3-spmc.html * or if the HW/chipset implements it, the S-EL2 FF-A SPMC https://hafnium.readthedocs.io/en/latest/secure-partition-manager/index.htm… Knowing the kind of S-EL0 service would help narrowing the effort for a migration. FF-A (https://developer.arm.com/documentation/den0077/latest/) is a modern evolution of MM (https://developer.arm.com/documentation/den0060/latest) and any functionality achieved by the MM protocol can be handled by FF-A. For example the MM_COMMUNICATE interface can be easily swapped by the FFA_MSG_SEND_DIRECT_REQ interface. Regards, Olivier. ________________________________ From: baopeng (A) via TF-A tf-a(a)lists.trustedfirmware.org<mailto:tf-a@lists.trustedfirmware.org> Sent: 21 February 2024 07:10 To: tf-a(a)lists.trustedfirmware.org tf-a(a)lists.trustedfirmware.org<mailto:tf-a@lists.trustedfirmware.org> Subject: [TF-A] Re: Request for help Hi Olivier Deprez, We have developed code based on the SPM_MM framework and do not want to reconstruct the code. However, we want to adapt the code to the SPMD framework. What should we do? ________________________________ Hi Baopeng, SPM_MM is the legacy implementation for a secure partition manager relying on the MM protocol. This implementation gets deprecated in favor of FF-A based implementations (what you refer to as SPMD + SPMC). Both implementations aren't compatible and it is discouraged to attempt co-locating both. It may be more palatable and future proof to transition all your SW stack to be compliant to FF-A standard. We may help you better if you tell a bit more about the reason for mixing both implementations in the same build. Regards, Olivier. ________________________________ From: baopeng (A) baopeng1@huawei.commailto:baopeng1@huawei.com Sent: 20 February 2024 02:19 To: tf-a-owner(a)lists.trustedfirmware.org tf-a-owner@lists.trustedfirmware.orgmailto:tf-a-owner@lists.trustedfirmware.org Subject: Request for help Dear Sir/ Madam, we need to support the simultaneous loading of SPMD and SPM_MM due to project reasons. However, we notice that the makefile of SPM_MM of ATF does not support the simultaneous loading of SPMD and SPM_MM by default. I would like to ask what is the main reason for making the current restrictions?

All if...else if constructs shall be terminated with an else statement.

by Nithin G

Hello, In the file lib/xlat_tables/xlat_tables_common.c and other associated files, there are instances where if...else if constructs lack an else statement, resulting in violations during the Coverity MISRA-C analysis for the ZynqMP platform. Addressing this issue added empty else statement to resolve the issue but it is related to core translational table logic function. Is it possible to address this issue? Please provide your suggestions. Regards, Nithin G

TF-A Node.js migration to v20

by Chris Kay

Hi folks, If you don’t use any of the JavaScript-based tooling from the TF-A repository then you can safely ignore this. I’ve just updated TF-A’s Node.js dependencies, including the minimum version of Node.js required to use the JavaScript-based hooks and tooling from the repository (previously v16, now v20). If you use these and you find that they have started throwing errors, make sure that you are rebased on the latest version of the integration branch, and then run: npm ci If you need to commit changes while the tools are erroring, you can commit with the `-n` flag to skip the commit hooks: git commit -n <usual commit flags…> Please let me know if you run into any issues. Cheers, Chris

Compatibility support for SPM_MM and SPMD

by baopeng (A)

Hi Olivier Deprez, One more question, the SPM_MM code will not be removed from the main repository, right? ________________________________ Hi Olivier Deprez, We use the SPM_MM framework mainly for read/write control of security variables. We do not want to modify the original application code at this time. At the same time we want to add support for the new SPMD framework based code. ________________________________ Hi Baopeng, By "code based on the SPM_MM framework" I assume you refer to a secure service running in a S-EL0 partition based on the MM protocol? If you can share this information, what kind of service is this implementing? RAS handling, secure variables, TPM back end, other? What kind of interface is needed to access the service? asynchronous with interrupts? synchronous with SMC from normal world? Another question is why do you need to collocate the SPMD if the MM implementation is already achieving the scenarios you need? Ideally you'd want to migrate this service to run on top of: * the EL3 FF-A SPMC https://trustedfirmware-a.readthedocs.io/en/latest/components/el3-spmc.html * or if the HW/chipset implements it, the S-EL2 FF-A SPMC https://hafnium.readthedocs.io/en/latest/secure-partition-manager/index.html...<https://hafnium.readthedocs.io/en/latest/secure-partition-manager/index.htm…> Knowing the kind of S-EL0 service would help narrowing the effort for a migration. FF-A (https://developer.arm.com/documentation/den0077/latest/) is a modern evolution of MM (https://developer.arm.com/documentation/den0060/latest) and any functionality achieved by the MM protocol can be handled by FF-A. For example the MM_COMMUNICATE interface can be easily swapped by the FFA_MSG_SEND_DIRECT_REQ interface. Regards, Olivier. ________________________________ From: baopeng (A) via TF-A tf-a@lists.trustedfirmware.orgmailto:tf-a@lists.trustedfirmware.org Sent: 21 February 2024 07:10 To: tf-a(a)lists.trustedfirmware.org tf-a@lists.trustedfirmware.orgmailto:tf-a@lists.trustedfirmware.org Subject: [TF-A] Re: Request for help Hi Olivier Deprez, We have developed code based on the SPM_MM framework and do not want to reconstruct the code. However, we want to adapt the code to the SPMD framework. What should we do? ________________________________ Hi Baopeng, SPM_MM is the legacy implementation for a secure partition manager relying on the MM protocol. This implementation gets deprecated in favor of FF-A based implementations (what you refer to as SPMD + SPMC). Both implementations aren't compatible and it is discouraged to attempt co-locating both. It may be more palatable and future proof to transition all your SW stack to be compliant to FF-A standard. We may help you better if you tell a bit more about the reason for mixing both implementations in the same build. Regards, Olivier. ________________________________ From: baopeng (A) baopeng1@huawei.commailto:baopeng1@huawei.com Sent: 20 February 2024 02:19 To: tf-a-owner(a)lists.trustedfirmware.org tf-a-owner@lists.trustedfirmware.orgmailto:tf-a-owner@lists.trustedfirmware.org Subject: Request for help Dear Sir/ Madam, we need to support the simultaneous loading of SPMD and SPM_MM due to project reasons. However, we notice that the makefile of SPM_MM of ATF does not support the simultaneous loading of SPMD and SPM_MM by default. I would like to ask what is the main reason for making the current restrictions?

Re: Request for help

by baopeng (A)

Hi Olivier Deprez, We have developed code based on the SPM_MM framework and do not want to reconstruct the code. However, we want to adapt the code to the SPMD framework. What should we do? ________________________________ Hi Baopeng, SPM_MM is the legacy implementation for a secure partition manager relying on the MM protocol. This implementation gets deprecated in favor of FF-A based implementations (what you refer to as SPMD + SPMC). Both implementations aren't compatible and it is discouraged to attempt co-locating both. It may be more palatable and future proof to transition all your SW stack to be compliant to FF-A standard. We may help you better if you tell a bit more about the reason for mixing both implementations in the same build. Regards, Olivier. ________________________________ From: baopeng (A) baopeng1(a)huawei.com<mailto:baopeng1@huawei.com> Sent: 20 February 2024 02:19 To: tf-a-owner(a)lists.trustedfirmware.org tf-a-owner(a)lists.trustedfirmware.org<mailto:tf-a-owner@lists.trustedfirmware.org> Subject: Request for help Dear Sir/ Madam, we need to support the simultaneous loading of SPMD and SPM_MM due to project reasons.

Purpose of ENABLE_PIE in TF-A without ASLR

by Igor Zhbanov

Hello, I'm trying to understand the purpose of ENABLE_PIE build flag. IIUC, it makes the BL* executables position-independent. But I could not find any ASLR or some other addresses randomization support. Therefore, could you please clarify, what is the point of building position-independent parts, if (most of the time?) they will be loaded at the fixed addresses? Thank you.

MMIO with pre/post indexing instructions

by ff

Hi, I am using hypervisors to allow execution of EL3 code directly and had to deal with MMIO caused by instructions that have post-indexing parameters. Xen community had to deal with this in 2022: https://www.mail-archive.com/xen-devel@lists.xenproject.org/msg113335.html This does not cause any trouble and have implemented ways to deal with this expeditiously. Yet, I wonder if it is desirable to from a synchronisation perspective? Cheers FF Compiling TFA 2.10 for PLAT=a80x0_mcbin The following line https://elixir.bootlin.com/arm-trusted-firmware/v2.10.0/source/drivers/marv… Is compiled as: win_reg = mmio_read_32(AMB_WIN_CR_OFFSET(win_id)); 4026d9c: f9470260 ldr x0, [x19, #3584] 4026da0: 9100e002 add x2, x0, #0x38 4026da4: b9400001 ldr w1, [x0] win_reg &= ~WIN_ENABLE_BIT; 4026da8: 121f7821 and w1, w1, #0xfffffffe *(volatile uint32_t*)addr = value; // post-indexing 4026dac: b8008401 str w1, [x0], #8 #gcc --version gcc (Ubuntu 10.3.0-1ubuntu1) 10.3.0 Copyright (C) 2020 Free Software Foundation, Inc.

Handling of normal world interrupts with BL31 PSCI handler

by caleb.ethridge＠analog.com

Hello, If normal world interrupts are received while invoking TF-A's PSCI reset handler, we have observed that the reset can be aborted. In TF-A's PSCI reset handler, a call out to OP-TEE is made before performing the platform-specific reset: https://github.com/ARM-software/arm-trusted-firmware/blob/master/lib/psci/p… https://github.com/ARM-software/arm-trusted-firmware/blob/master/services/s… When OP-TEE is entered, it is possible to receive foreign (normal world) interrupts, which invokes the procedure described here: https://optee.readthedocs.io/en/3.16.0/architecture/core.html#deliver-non-s… When the SMC call is aborted as described above, this results in the reboot failing. Linux does not retry the PSCI reset (https://github.com/torvalds/linux/blob/master/drivers/firmware/psci/psci.c#…). This makes sense because it is not expecting the SMC call to fail (it expected to make an uninterruptable SMC call into the secure monitor, not a call into OP-TEE). If OP-TEE itself is setup to handle PSCI reset calls, it also handles them in (uninterruptable) SMC context: https://github.com/OP-TEE/optee_os/blob/master/core/arch/arm/sm/psci.c#L140 https://github.com/OP-TEE/optee_os/blob/master/core/arch/arm/sm/sm_a32.S#L96 Based on this, we see two possible solutions: a) Masking the non-secure interrupts in BL31 while we are doing a reset b) Removing the call to OPTEE in the reset handler so that we never leave the SMC context Which option do you suggest? Or are we missing an important detail here? Thanks, Caleb
