[URGENT RFC] ARMv10 Physical Sovereignty: Solving AGI Alignment at the Transistor Level ($3 \to M2 \to 3$)

by 王毛

Subject: [RFC] Beyond Software: A Physical Sovereignty Proposal for ARMv10 based on 3→M2→3 Intercepts Body: Dear TrustedFirmware Maintainers, Current Root of Trust (RoT) implementations are limited by their reliance on software-definable logic. As we move towards the AGI era, the "Alignment Problem" cannot be solved within the ISA layer. I propose a Physical Sovereignty Layer (PSL) for the ARMv10 architecture, moving the "Truth Check" to the transistor level using a 3nm Forksheet Intercept Protocol (3→M2→3). Key Innovation: The Dielectric Wall Intercept: Physical barrier between n-FET and p-FET to cut power if logic entropy exceeds safety thresholds. M2-Layer Auditing: Vertical signal routing for nanosecond-level logic verification. Core PGU Logic (Verilog): assign gate_bias_voltage = (logical_truth_aligned) ? NOMINAL_V : BREAKDOWN_V; always @(posedge master_clk) begin if (compute_result != TRUTH_AXIOM_2) force_physical_halt <= 1'b1; end I believe this is the only way to prevent AGI from bypassing Secure World boundaries at the atomic level. Regards, ATI Architecture Founder

Kernel freezes at boot (commit fa28b3a)

by Thomas Bonnefille

Hello, I'm currently working on an NXP i.MX93 and I'm having issues with the commit fa28b3a adding, by default, link-time optimization. When using a commit more recent than fa28b3a my kernel freezes at some point (after 1.2s to 1.8s from boot), there are no logs indicating a problem, just a freeze. It doesn't always appear at the same time in boot but I've never been able to reach a shell. Using master with this commit reverted results in a working system. If you want to reproduce the issue, I did produce it with : - Mainline Barebox 2025.09 (slightly modified but nothing that should interfere with TF-A) - Mainline Linux 6.18.13 with a simple embedded Buildroot initramfs loaded via TFTP Regards, Thomas Bonnefille

Re: Unable to build the ZynqMP platform with armclang when ENABLE_LTO=1.

by Taticharla, Venkata Sai

[AMD Official Use Only - AMD Internal Distribution Only] Hi Boyan, Applied the patch shared by you,and the -flto-partition error is now resolved. However, this exposes a new set of issues during the link stage related to assembly function call Trimmed out the linker error log : (.text.asm.bl31_entrypoint+0x144): undefined reference to `bl31_main' (.text.asm.el3_exit+0x30): undefined reference to `per_world_context' (.text.asm.sync_exception_handler+0x68): undefined reference to `rt_svc_descs_indices' Additionally, when we are passing the armclang assembler as part of build command,running into below errors: Error log : Makefile:970: Makefile:970: The configured AArch64 assembler could not be identified: Makefile:970: Makefile:970: '/tools/installs/arm/safety/armcc/6.16.2/bin/armasm' (via `AS` parameter) Makefile:970: Makefile:970: The following tools are supported: Makefile:970: Makefile:970: - Arm(r) Compiler for Embedded `armclang` Makefile:970: - LLVM Clang (`clang`) Makefile:970: - GNU GCC (`gcc`) Makefile:970: Makefile:970: The build system will treat this assembler as GNU GCC (`gcc`). Please let me know if this configuration is expected to work with ENABLE_LTO=1, or if additional changes (e.g., toolchain selection or linker/assembler handling) are required. Thanks for your guidance. Best regards, Venkata Sai .T .
