Normalized the AI disclosure comment to one fixed line per file (#740)

2026-09-15T21:17:26Z

The per-edit disclosure named the product and model, so every agent and every model version appended another line. 74 files carried two to four of them, and the same five products had accumulated 13 spellings -- Copilot against GitHub Copilot, Claude Sonnet 4.6 against claude-sonnet-4.6, four spellings of Codex. Twenty assembly lines carried a doubled comment marker, `; //` or `@ //`. Every file now carries exactly one line, fixed text naming no product: Portions of this file were generated with AI assistance. It is written with the comment character that file already uses, so the `;` and `@` assembly files keep theirs and the doubled markers are gone. Precise attribution stays on the commit, where the Assisted-by trailer is per-change, dated and attached to the diff it describes. A header line cannot hold that record honestly, because the code it names gets rewritten and the line stays. A file-level flag answers whether; the history answers who. Comment-only. 455 files, 455 insertions and 574 deletions: every removed line was a disclosure line, every added line is the fixed text, and no file is left with zero or with more than one. `scripts/check_ports.sh` passes, including the reproducibility check that would catch a ports_arch master and its generated copies drifting apart. Recompiled against dev, every file that builds without a vendor toolchain gives a byte-identical object: 19 of 19 C files under common, 100 of 100 GNU assembly files, and all 16 assemblable files whose comment marker changed. The 10 remaining marker changes are ac5 and IAR sources where `;` already started the comment and only the redundant `//` was removed. Assisted-by: Claude Code (Opus 5)

Replaced the stale system stack switch pseudo-code in the ARMv7-A ports with comments that describe what the code actually does (#735)

2026-09-11T17:27:32Z

The context save, vectored context save and system return routines in the ARMv7-A ports carried pseudo-code comments claiming that they saved the thread stack pointer and then switched to _tx_thread_system_stack_ptr. Neither of those things happens, and none of these ports references that variable outside an unused IMPORT in their example builds. On ARMv7-A each processor mode has its own banked stack pointer. The IRQ handler branches to _tx_thread_context_save while still in IRQ mode, so the core's banked IRQ stack already serves as the system stack, and the thread stack pointer is stored in the control block by _tx_thread_context_restore, and only when the interrupt results in preemption. The scheduler runs on the banked SVC mode stack that the startup code sets up. There is nothing for a software stack switch to do. The comments were therefore misleading rather than merely redundant, and had led at least one user to try to restore the code they described. They are now replaced by a description of the actual mechanism. The AArch64 SMP ports keep their comments unchanged, because ARMv8-A does not bank a stack pointer per processor mode and those ports do reload _tx_thread_system_stack_ptr[core] explicitly. This is a comment-only change. Every changed line is a comment, and all twenty-five GNU variants still assemble cleanly for their target core. The fourteen files under ports/cortex_a{5,7,8,9,12,15,17} were regenerated from ports_arch/ARMv7-A/threadx/common/src/tx_thread_system_return.S with ports_arch/ARMv7-A/update.sh. The ARMv7-A SMP ports have no generator, so those files were edited directly. Fixes #734 Assisted-by: Copilot (Opus 5)

Added bash A profile update scripts and restored ports_arch as their source (#592)

2026-08-09T14:55:29Z

The ARMv7-A and ARMv8-A ports are generated by update.ps1, which needs PowerShell, so the cortex-a job in ports_arch_check ran on a Windows image and nobody could reproduce it locally on Linux. Add update.sh beside each update.ps1, with the same cores, compilers, copy sets and patches, and move the job to the same Linux image as everything else. The bash scripts were checked against the PowerShell ones by comparing what each reports as drifted. They agree exactly on the 63 files the Windows job last reported, and differ on 12 more, which turn out to be a defect in update.ps1 rather than in the port. Its two .cproject patterns are written as 'value=`"cortex-a7`"' with backticks that survive into the pattern, so that replacement has never matched, while the neighbouring Cortex-A7.NoFPU pattern has no backticks and always worked. The result is that the AC6 example builds for the A5, A8, A9, A12, A15 and A17 cores name cortex-a7 as their CPU while their FPU string is correct. The bash scripts do what the PowerShell ones intended, so regenerating corrects those twelve files. Restore ports_arch as the source for the rest. The implementation of _tx_thread_smp_time_get from #555 was applied to the twenty four generated SMP ports and never to ports_arch, which still held MOV x0, #0 with a FIXME comment, so regenerating would have replaced a working generic timer read with a stub. That implementation now lives in the source. The remaining differences are cosmetic and resolve in favour of the source: a trailing blank line in 38 copies of tx_thread_schedule.S and comment spacing in one tx_port.h. Note that the Cortex-A VFP fix is already present in ports_arch and was never at risk, contrary to what the description of the port consistency checks change said before this was measured. Extend scripts/check_ports.sh to run the A profile generators too, and make it fail when a generator fails or is missing rather than reporting a clean tree, which would have been a false pass. Pin every workflow to ubuntu-24.04. ubuntu-latest already resolves to that image, so nothing changes today, but a future migration becomes a deliberate commit rather than something that happens underneath the -m32 builds.

Fix VFP build failure in Cortex-A tx_thread_schedule.S

2026-01-06T16:07:48Z

When TX_ENABLE_VFP_SUPPORT is defined, the build fails due to missing IRQ_MASK and FIQ_MASK symbols in the restore logic. This adds the local definitions (0x80 and 0x40) to tx_thread_schedule.S to match tx_thread_interrupt_restore.S, enabling successful compilation on GNU and AC6 Cortex-A ports.

Update copyright.
