cmake: fixed THREADX_ARCH undefined when building as standalone library (#540)

2026-05-29T12:50:52Z

CMake loads the toolchain file during the first project() call. Variables set in the toolchain (THREADX_ARCH, THREADX_TOOLCHAIN) were therefore not visible before project() was invoked. Commit 2c16114a moved project() after those checks to conditionally select LANGUAGES and CMAKE_TRY_COMPILE_TARGET_TYPE for Windows, which broke standalone builds that rely on the toolchain to supply THREADX_ARCH. Fixed by calling project(threadx LANGUAGES C) first so the toolchain is sourced, then checking THREADX_ARCH, then conditionally enabling ASM via enable_language(ASM) for non-Windows ports. The CMAKE_TRY_COMPILE_TARGET_TYPE override was removed from CMakeLists.txt because every toolchain file in cmake/ already sets it to STATIC_LIBRARY where needed.

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)

Added RISC-V board Bananapi BPI-F3 (SpacemiT K1 SoC) BSP Support (#531)

2026-05-25T19:59:17Z

* Add BananaPi BPI-F3 BSP support Add RISC-V supervisor support to the rv64/gnu port and provide a complete board support package for the BananaPi BPI-F3 (SpacemiT K1 SoC, X60 cores). Port changes (risc-v64/gnu): - Guard all CSR accesses with TX_RISCV_SMODE to select S-mode registers (sstatus/sepc/sie/sret) vs M-mode (mstatus/mepc/mie/mret) in context_save, context_restore, schedule, system_return, interrupt_control, and stack_build. - Add S-mode TX_INT_ENABLE/TX_DISABLE and inline TX_RESTORE macros to tx_port.h. - Add TX_RISCV_SMODE CMake option to CMakeLists.txt. BananaPi BPI-F3 BSP (example_build/bananapi-f3): - Boot flow: FSBL → OpenSBI (M-mode) → U-Boot (S-mode) → ThreadX - S-mode trap handler with context save/restore integration - SBI legacy ecall timer at 10 Hz (24 MHz timebase) - PLIC driver with S-mode context, stale-IRQ drain, and callbacks - PXA-compatible UART0 console (115200 8N1) - Linker script at 0x200000 load address Tested on risc-v board, BananaPi BPI-F3 hardware. Signed-off-by: Akif Ejaz * Fixed S-mode context restore and PLIC spurious IRQ handling - tx_thread_context_restore.S (non-nested path): set SPIE(0x20) alongside SPP(0x100) so sret re-enables interrupts in the restored thread. - tx_thread_context_restore.S (both S-mode paths): use FS=Dirty (0x6000) instead of FS=Initial (0x2000) to match tx_thread_schedule.S and prevent FP register corruption across context switches. - plic.c (plic_irq_intr): return early when plic_claim() yields 0 (no pending interrupt) to avoid completing a spurious IRQ ID 0, which is undefined behavior per the PLIC spec.
