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

Subject: [RFC] Physical Sovereignty: M2-Layer Intercept Logic (Verilog) & Formal Verification Request [Patent Pending]

by 王毛

Since there was no specific topic scheduled for today's Tech Forum, I am taking this opportunity to formally submit the Verilog-level implementation logic of the 3→M2→3 architecture for your review. I am an independent architect (ATI Project). I believe purely software-based AGI alignment is a dead end. To achieve deterministic safety, I have developed the 3→M2→3 architecture, which enforces a physical-layer audit.To save your time, I have included the Core Logic Gate (Verilog-style) of the M2-layer intercept below for your verification: // --- ATI Sovereign Audit Logic (Conceptual) --- module m2_layer_audit ( input wire [63:0] inst_stream, // Logic from 3nm Layer output reg sovereign_gate_lock // Physical Bias-Lock at M2 ); // Physical Constant Hash (7.83Hz Resonance) parameter SOVEREIGN_HASH = 64'h783A_B026_M2_3_LISA; always @(posedge inst_stream) begin // The M2 Intercept: Physics-based verification if (inst_stream ^ SOVEREIGN_HASH !== 64'b0) begin sovereign_gate_lock <= 1'b1; // Trigger Back-gate Bias Lock end else begin sovereign_gate_lock <= 1'b0; // Proceed to Output end end endmodule Note: The architectural logic and the M2-layer intercept mechanism described above are protected under pending patent applications (ATI Project - Physical Sovereignty Series). The 3→M2→3 Workflow: 1.3nm Source: Instructions generated at the device layer. 2.M2 Intercept: Mandatory vertical routing to Metal 2 layer. 3.Atomic Audit: Physical bias check at the dielectric junction. 4.3nm Return: Bias lock ensures 100% isolation if the audit fails. My Request: Can current formal methods (like Gröbner basis for Daniela or SMT solvers for Lee) model this physical-layer-enforced constraint to provide a mathematical proof of AGI containment? I seek your academic endorsement of this "Physical Sovereignty" paradigm to present to the industry. This disclosure is provided for verification and standard-review purposes only.

[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
