no longer get warnings from ThreadX headers (#713)
* Marked every published ThreadX include directory as SYSTEM so applications no longer get warnings from ThreadX headers
Commit 8c3c08f added the SYSTEM keyword to the target_include_directories
call in common/CMakeLists.txt, but the same call in every port, in the
SMP common directory's consumers, in the POSIX and FreeRTOS compatibility
layers, and for the generated tx_user.h directory was left unchanged.
A consumer building with a strict warning set therefore still saw
diagnostics coming from tx_port.h and from the compatibility layer
headers, which is exactly what the original change set out to avoid.
Added the SYSTEM keyword to all of those calls so CMake emits -isystem
rather than -I for every directory holding a ThreadX public header. The
ARMv7-M, ARMv8-M, ARMv7-A and ARMv8-A architecture sources under
ports_arch were updated alongside the ports they generate, keeping the
two in step.
Directories that are PRIVATE to an example or test build were left as
they are, since nothing is published from them.
Fixes #290

* Stopped apt-get update being a gate it was never meant to be
apt-get update fails if any configured repository serves a bad index,
including ones this project never reads. The GitHub runner image carries
Google's and Microsoft's apt repositories, and a Hash Sum mismatch from
Google's, their CDN caught mid-publish with the index and the Release
file eight hours apart, failed all three attempts and turned a run red
over a browser nobody was installing.
Made a failed update warn and carry on, leaving apt-get install as the
gate. Nothing is weakened by that: the install still exits on a package
it cannot find, so an unreachable archive still stops the script, one
step later and naming the package it could not get, which is a better
diagnostic than a hash mismatch in a repository nobody asked for.
Disabling third-party sources before updating would keep the update
strict, but this script also runs on a contributor's own machine, and
rewriting someone's apt configuration to suit CI would be worse than
tolerating a stale index for an archive we do not read.

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.
