Re: [PATCH] fix(st): reset SoC instead of panic() on MMC init failure

by Yann Gautier

Hello, Thanks for the patch and the detailed commit message. For ST boards, we usually treat this kind of issues with watchdog. But I admit some watchdogs patches are still missing upstream. I'll try to send them soon. We are discussing internally to see if this particular use-case could be done as you proposed. I'll get back to you next week about this, when one of my colleagues comes back. Maybe this could be selected with a compilation flag. About the patch submission, TF-A uses gerrit, and we do not merge patches from mailing-list like Linux does.

Firmware-A v2.15 release code freeze notification

by Harrison Mutai

Hi All, The next release of the Firmware-A bundle of projects tagged v2.15 has an expected code freeze date of 15/05/2026. Refer to the release cadence section from TF-A documentation (https://trustedfirmware-a.readthedocs.io/en/latest/about/release-informatio…). Closing out the release takes around 6-10 working days after the code freeze. v2.15 release preparation tasks are on-going and well progressed. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind reminder and a matter of sharing CI resources, please launch CI jobs with care e.g.: * For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run). * For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 labels in the middle of the patch stack). * Carefully analyze results and fix the change if required, before launching new jobs on the same change. * If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued. Thanks & Regards, Harrison on behalf of the TF-A team

Why can TF-A code still run in an address space that it itself has set to be "Execute-Never"?

by Hughard

*Environment:* - *Exception Level:* EL3 (AArch64) - *Component:* [image: 微信图片_20260304154227_69_553.png] ARM Trusted Firmware (TF-A) - BL2/BL31 - *Platform:* Arm FVP / Base_Revc_2xAEMvA / Bare Metal Debug /ARMAEM-A_MP_0 [ Arm Development Studio ] *Observation:* I am observing a strange thing of the ARMv8-A architecture's memory translation rules. Despite the translation table explicitly marking the memory region as Execute-Never, the CPU continues to fetch and execute instructions from this region without triggering an exception. I'm a student with limited hardware background, and I'm learning TF-A and doing porting during my internship. I'd really like to know the reason behind this. *Code I use:* ARM Trusted Firmware v2.13 *Github:* github.com/.../arm-trusted-firmware <https://github.com/ARM-software/arm-trusted-firmware> *Take the case of running BL31 in Development Studio as an example. （Breakpoint at the beginning of bl31_setup）* *Technical Evidence (Verified via Debugger):* SCTLR_EL3: M=1 (MMU enabled), WXN=1 (Write implies execute-never), I=1 (Instruction Cache enabled). BL31’s code is loaded at: 0x04003000 Translation Table Entry (L3 Descriptor): 0x00400000_04003743 Physical Address: Verified via TTBR0_EL3 walk. (0x04034600 -> 0x04035003 -> 0x04037003 -> 0x00400000_04003743) Attributes: AP[2:1]=0x1 (Read/Write), XN=1 (Execute-Never), AF=1, SH=0x3 (Inner Shareable), NS=0, AttrIndx = 0x0 (See the MAIR_EL3) MAIR_EL3: 0x4404FF (Attr0 = 0xFF, Normal Memory). Synchronization Performed: DSB SY + ISB The PC (Program Counter) is confirmed to executing from the first instruction of BL31 code at address 0x04003000. *The Problem:* This evidence should point to one conclusion: it cannot execute the BL31 code and will report an error. However, the execution flow remains uninterrupted. From my point of view, it should cause "ESR_EL3 = 0x8600000F", which means: "Instruction Abort taken without a change in Exception level. Used for MMU faults generated by instruction accesses and synchronous External aborts, including synchronous parity or ECC errors. Not used for debug-related exceptions." + "Permission Fault, level 3". As I test on a real fpga by using similar code by making some changes at the end of BL1 so that it would execute BL2 at level EL3 (but instead of bl2_el3_entrypoint.S, it would execute bl2_entrypoint.S). In this case, it throws an error when it jumps to the first instruction of BL2, and the ESR_EL3 register displays "Permission Fault, level 3". If I add the instruction to disable the MMU (setting SCTLR_EL3.M_BIT to 0) at the end of BL1, and change the function to enable the MMU in the official code "arm_bl2_plat_arch_setup" to use "enable_mmu_el3(0)", it can run normally on the FPGA and bring up the UEFI. (In this real-world test, I used DDR instead of SRAM, so BL2 and BL31 were also placed here after being parsed.) *Request for Help:* The above content is beyond my comprehension; even my internship supervisor doesn't understand the reasoning behind it. Therefore, I need help from the experts on this forum. *Reference:* DDI0487M_a_a-profile_architecture_reference_manual.pdf ARM Development Studio@Docs (such as Docs/ARM_A/xhtml/AArch64-esr_el3.html) armv8_a_address_translation version1.1

TF-A Tech Forum @ April 2, 2026

by Scaria Kochidanadu

Hi, this is Scaria Kochidanadu, from Texas Instruments and would like to present : "s2idle-driven Low Power Mode Selection using PSCI on AM62L", in the TF-A tech forum on April 2nd, 2026. We present a runtime-configurable low power mode(LPM) management approach for *PSCI* firmware in ATF, implemented on the AM62L SoC, a 2-core system with A53 cores. The primary goal of this session is to gather feedback on the *suitability of this design for upstreaming*, and to get guidance on key challenges encountered during implementation before proceeding with further debugging and optimization. In this design, we transition to an *s2idle-based flow* where Linux cpuidle framework and governor drive idle state selection, from the multiple platform-specific standby and low power modes that are provided in the devicetree. The PSCI driver in ATF is then responsible for the validation of the idle-states passed and the entire suspend-resume flow, with the *Operating-System Initiated (OSI) mode in PSCI*. As ATF now handles the full suspend-resume flow, it has the responsibility of managing the powering down and bringing up of the cores, along with the state of the system. We observe issues related to core *coordination in a multi-core system*, as well as system state management during resume, including *GIC* and (*Interrupt Translation Service*)ITS context handling. In this session, we will present our suspend and resume design in the AM62L PSCI implementation and discuss these challenges in detail. We would also like to discuss the *current validation logic* for the context-preserving retention states like standby and our approach to enable standby mode. We are particularly interested in feedback on whether this *OS-driven LPM selection model aligns with ATF design expectations*, and on recommended approaches for handling *inter-core coordination and system state restoration within PSCI-based flows*. Regards, Scaria Kochidanadu, Texas Instruments.

As RMM and the rest of the software stack are being prepared for the initial v2.0 migration, TF-A has introduced a new build configuration flag, RMM_V1_COMPAT, to control the world-switch behaviour between RMM v1.x and RMM v2.0 [1] . This flag is enabled by default, meaning the default behaviour currently corresponds to RMM v1.x. Once TF-RMM is ready to merge the v2.0 support, the default value of this flag will be changed to 0. The flag also updates the EL3–RMM interface major version, allowing incompatibility with TF-A related to this build configuration to be detected at runtime. We expect the initial v2.0 changes in TF-RMM to be merged by the end of this month. As mentioned in the previous email, we will create a v1.x branch prior to this and provide an update here. [1] https://git.trustedfirmware.org/plugins/gitiles/TF-A/trusted-firmware-a/+/r… Best regards, Soby Mathew From: Soby Mathew via tf-rmm <tf-rmm(a)lists.trustedfirmware.org> Date: Thursday, 5 February 2026 at 09:42 To: tf-rmm(a)lists.trustedfirmware.org <tf-rmm(a)lists.trustedfirmware.org> Cc: nd <nd(a)arm.com> Subject: [tf-rmm] RMMv2.0 implementation plan for TF-RMM Hi Everyone, The RMM v2.0 Beta 0 specification has been published here: https://developer.arm.com/documentation/den0137/latest/ As you may have noticed, this release introduces breaking changes to the RMI APIs (host side), while the RSIs (guest side) remain backward compatible. Nearly all ABIs are affected, and the scope of these changes makes it highly disruptive to maintain support for both RMI v1.x and RMI v2.0 within the same codebase. We do not expect RMI v1.x to be deployed in production, and retaining support for it would increase development overhead and the risk of introducing bugs. A more pragmatic approach is to branch the current RMM codebase at the RMI v1.x ABI and then migrate the mainline to the RMI v2.0 ABI. This will be a breaking change for host-side components that rely on the older RMI ABI. Given the extent of the ABI changes, significant effort will be required to align with RMI v2.0, and this approach allows the team to focus on upstreaming the new ABI support efficiently. The initial RMI v2.0 upstreaming will consist of a series of commits that together form an initial RMM implementation targeting the RMM v2.0 specification. This initial implementation will not be fully feature-complete with respect to the v2.0 spec, and we expect to continue layering additional RMM v2.0 ABI-related changes on top as the implementation matures during the course of the year. That said, we intend to maintain integration with an externally available, compatible Linux host kernel branch throughout this process. The initial RMI v2.0 RMM implementation will be compatible with an initial v2.0-based host kernel, and we will notify the mailing list once this integration is available to pick up (likely end of March ’26). If and when we need to introduce further ABI changes that break compatibility with a previously published kernel branch, we will call this out explicitly in advance and indicate when an updated kernel branch will be available for integration. We plan to keep RMI v1.x ABI as a separate branch and selectively merge bug fixes on a request or need basis. Please let us know if you have any concerns regarding this plan within the next two weeks. Best Regards Soby Mathew
