Fixed race condition and message loss in Cortex-M ports (#523)

2026-04-29T13:10:57Z

* Fixed race condition and message loss in Cortex-M GNU, AC6, and IAR ports (#516) - Added compiler memory barriers to BASEPRI management functions in tx_port.h. - Added architectural barriers (DSB/ISB) to scheduler return paths in tx_port.h and tx_thread_system_return.S to prevent fall-through before context switch. - These changes address spurious thread resumption and lost messages, especially when TX_NOT_INTERRUPTABLE is enabled. - These changes ensure that pending interrupts (specifically PendSV) are recognised before subsequent instructions are executed, following Kairalite's feedback and ARM architectural guidelines. Assisted-by: Gemini (Gemini 2.0 Flash) ----- * Added a comment in common/tx_queue_cleanup to document why the NI path omits revalidation guards - In `TX_NOT_INTERRUPTABLE` mode, the caller keeps interrupts disabled across the entire cleanup call, so the race window that makes the guards necessary in the interruptable path cannot occur. Add a comment explaining this, and noting that all paths that resume a suspended thread clear tx_thread_suspend_cleanup before calling _tx_thread_system_ni_resume, making double-cleanup impossible. This prevents future false-positive suggestions (e.g. from AI tools) to add redundant checks to the NI path.
