Bounded the wait for the delayed suspension window (#645)

2026-08-20T12:50:15Z

threadx_thread_delayed_suspension_test waits for an interrupt to land while thread 2 is part way through suspending, and waits for it with no bound: while(delayed_suspend_set == 0) { tx_thread_wait_abort(&thread_2); tx_thread_relinquish(); } How long that takes depends on the build to a degree that is easy to miss. The loop finishes in between a tenth of a second and three seconds in four of the five ThreadX configurations. In trace_build it took 490 seconds, which was 40 percent of the whole ThreadX suite and more than every other test in that configuration put together. This is the third test in these suites built the same way, after threadx_thread_priority_change and threadx_thread_wait_abort_and_isr_test: spin until an interrupt happens to land in a narrow window, with nothing to stop the spin if it does not. The other two have been given bounds already. Give this one a wall clock budget too, for the same reason as the last: a tick is delivered only when the port's timer thread runs, so the tick clock falls behind real time under load or instrumentation, and instrumentation is exactly what trace_build turns on. The check after the loop needs care that the other two did not. It compares thread_2_counter against thread_2_counter_capture, and the capture is taken inside the interrupt handler at the moment the window is hit. Leaving that check in place after a run that never reached the window would compare a live counter against the zero it was initialised to and report a defect that is not there. So the check is skipped when the window was not reached, and the run says so. Reaching the window still exercises it exactly as before. Verified both ways in trace_build, which is the configuration that was slow: the window is reached in 8 seconds here and the test passes as it always did, and with the budget forced to zero the test reports that the window was not reached and passes without the dependent check firing.

Added win64 ports of ThreadX and ThreadX SMP (#529)

2026-05-26T21:17:40Z

Windows x64 port and regression suite This PR adds the Windows x64 (Win64) simulation port for both the standalone and SMP variants of ThreadX, along with the full CMake build and test infrastructure needed to run the regression suite on Windows. New ports Win64 standalone (ports/win64/vs_2022): self-contained Windows simulation port using Win32 threading primitives as virtual cores. Includes CMake integration, build/test scripts, and MSVC project files. Win64 SMP (ports/win64_smp/vs_2022): multi-core Windows simulation port. Supports up to 4 virtual cores backed by Windows host threads. Scheduler and timer improvements The initial port used coarse polling and synchronous SuspendThread/ResumeThread pairs throughout the scheduler hot path. Several rounds of optimization reduced the SMP regression suite runtime from ~150 s to ~78 s (-48%), with no regressions: - Replaced scheduler polling with an event-driven wake path; switched the simulated timer to one-shot rearming to eliminate catch-up ticks. - Skip SuspendThread when _tx_thread_preempt_disable != 0 (new suspension type 3) -- the primary optimization, yielding up to 7.9x speedup on preemption-heavy tests. - Skip SuspendThread when a thread is spinning on the Win32 critical section (suspension type 4), and fix a stale-TLS bug in _tx_win32_critical_section_obtain that could stamp mutex_access on the wrong virtual core. - Added a 2 ms scheduler event timeout (matching the Linux SMP port) to prevent stalls on any missed SetEvent. - Enabled high-resolution waitable timers (SetWaitableTimerEx) for accurate 100 Hz tick cadence. - Increased TX_WIN32_CONTENTION_PAUSE_COUNT from 64 to 256 to reduce SwitchToThread overhead under heavy CS contention. Build and test infrastructure - Hardened the Windows build wrapper (scripts/build_tx.ps1): invoke Ninja directly for Ninja build trees, fix timeout detection, add a default build timeout, and limit fallback replay to real timeout cases. - Added -Clean support to Windows test scripts to remove stale CTest state before each run. - Skip Visual Studio DevShell re-entry when the active MSVC environment already matches the requested architecture. - Fixed scripts/build_tx.sh (Linux) regression source generation: replaced brittle exact-string insertion with line-based matching so the interrupt dispatcher hook is inserted reliably for both simulator ports. Test suite updates - Introduced test/tx/regression/threadx_test_port.h with portable macros (TX_TEST_POINTER_WORD, TX_TEST_STORE_POINTER) for storing pointers in test arrays on 64-bit targets where ULONG remains 32-bit. - Adjusted pool-capacity and pointer-storage patterns in regression tests to use ALIGN_TYPE-sized slots, making the suite correct on 64-bit hosts. - Restored stricter event flag, sleep, and timer expectations now that port-level fixes make prior Windows accommodations unnecessary. - Tightened SMP watchdog and clean-build timeout defaults. Version metadata Updated Win32, Win64, and Win64 SMP port version strings to 6.5.1.202602. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Codex (gpt 5.5)
