From efe70fecf8b25645a112cf2d8419b5983d48492e Mon Sep 17 00:00:00 2001 From: iamaperson000 Date: Sat, 30 May 2026 17:16:05 -0400 Subject: [PATCH 01/28] macOS: add Platform/Mac files and Apple Silicon CMake support Adds the foundational macOS/Apple Silicon platform-support: Platform-specific code (new files): - rts/System/Platform/Mac/CpuTopology.cpp: stubs the CPU topology API on top of std::thread::hardware_concurrency() and sysctl for cache sizes (macOS exposes no portable per-core P/E topology). - rts/System/Platform/Mac/ThreadSupport.cpp: native pthread wrappers (Suspend/Resume are no-ops on macOS). Build system (CMake): - if(APPLE)/NOT APPLE branches in rts/CMakeLists.txt, rts/builds/{legacy,dedicated}/CMakeLists.txt, rts/lib/glad/CMakeLists.txt, rts/System/CMakeLists.txt, test/CMakeLists.txt, and tools/unitsync/CMakeLists.txt so the Mac branch picks up the new Platform/Mac sources, pulls libunwind only on non-Apple UNIX, and links Foundation / objc / EGL (the latter via find_library with Homebrew/MESA_PREFIX hints). Mac-gated source changes: - Rendering/GlobalRendering.cpp: EGL-on-CAMetalLayer path (Kopper/Zink via Mesa) for context creation and SwapBuffers, all behind #if defined(__APPLE__). - Game/LoadScreen.cpp, Rendering/GL/{myGL.cpp,glxHandler.*}: skip GLX (Mac has no X server) and skip the Lua intro screen (EGL/Metal incompatibility), all behind #ifdef. - System/Platform/{ThreadAffinityGuard.cpp,.h}: stub the affinity API on macOS, which exposes no portable equivalent of sched_setaffinity. - System/MemPoolTypes.h, Sim/Units/Unit.cpp: Apple-only fallbacks where pthread_t is an opaque pointer and where std::views::enumerate is unavailable in older Apple Clang libc++. - test/other/testMutex.cpp: use os_unfair_lock instead of linux/futex.h on macOS. Mac-driven but platform-neutral fixes: - System/Platform/Threading.cpp: replace std::ranges::find_if with std::find_if (still C++17, compiles everywhere). - System/SafeUtil.h: add missing include needed by libc++. - lib/smmalloc/smmalloc.h: relax POD static_assert to is_trivially_copyable_v (avoids deprecated is_trivial). - lib/smmalloc/smmalloc_generic.cpp, lib/assimp/include/ assimp/{matrix3x3,matrix4x4,quaternion,vector2,vector3}.inl: add missing / includes (libstdc++ transitively included them; libc++ does not). - AI/Wrappers/CUtils/Util.c: const-correct the macOS branch of util_fileSelector to match Apple's scandir signature. Linux and Windows code paths are either unchanged (#ifdef-guarded) or pick up trivially-compatible standard library calls; this commit is additive from their perspective. --- AI/Wrappers/CUtils/Util.c | 2 +- rts/CMakeLists.txt | 2 +- rts/Game/LoadScreen.cpp | 4 + rts/Rendering/GL/glxHandler.cpp | 4 +- rts/Rendering/GL/glxHandler.h | 4 +- rts/Rendering/GL/myGL.cpp | 4 + rts/Rendering/GlobalRendering.cpp | 155 +++++++++++++++++++ rts/Sim/Units/Unit.cpp | 7 + rts/System/CMakeLists.txt | 3 +- rts/System/MemPoolTypes.h | 10 +- rts/System/Platform/Mac/CpuTopology.cpp | 52 +++++++ rts/System/Platform/Mac/ThreadSupport.cpp | 40 +++++ rts/System/Platform/ThreadAffinityGuard.cpp | 13 +- rts/System/Platform/ThreadAffinityGuard.h | 13 +- rts/System/Platform/Threading.cpp | 2 +- rts/System/SafeUtil.h | 1 + rts/builds/dedicated/CMakeLists.txt | 16 +- rts/builds/legacy/CMakeLists.txt | 18 ++- rts/lib/assimp/include/assimp/matrix3x3.inl | 1 + rts/lib/assimp/include/assimp/matrix4x4.inl | 1 + rts/lib/assimp/include/assimp/quaternion.inl | 1 + rts/lib/assimp/include/assimp/vector2.inl | 1 + rts/lib/assimp/include/assimp/vector3.inl | 1 + rts/lib/glad/CMakeLists.txt | 6 +- rts/lib/smmalloc/smmalloc.h | 2 +- rts/lib/smmalloc/smmalloc_generic.cpp | 1 + test/CMakeLists.txt | 16 +- test/other/testMutex.cpp | 22 ++- tools/unitsync/CMakeLists.txt | 10 +- 29 files changed, 376 insertions(+), 36 deletions(-) create mode 100644 rts/System/Platform/Mac/CpuTopology.cpp create mode 100644 rts/System/Platform/Mac/ThreadSupport.cpp diff --git a/AI/Wrappers/CUtils/Util.c b/AI/Wrappers/CUtils/Util.c index c33d2e418e8..b2c2eeb61e5 100644 --- a/AI/Wrappers/CUtils/Util.c +++ b/AI/Wrappers/CUtils/Util.c @@ -488,7 +488,7 @@ static void util_initFileSelector(const char* suffix) { } #if defined(__APPLE__) -static int util_fileSelector(struct dirent* fileDesc) { +static int util_fileSelector(const struct dirent* fileDesc) { #else static int util_fileSelector(const struct dirent* fileDesc) { #endif diff --git a/rts/CMakeLists.txt b/rts/CMakeLists.txt index 001ea7cb6ba..f88de071b70 100644 --- a/rts/CMakeLists.txt +++ b/rts/CMakeLists.txt @@ -106,7 +106,7 @@ if (USE_MIMALLOC) endif (USE_MIMALLOC) -if(UNIX AND NOT (CMAKE_SYSTEM_NAME MATCHES "OpenBSD")) +if(UNIX AND NOT APPLE AND NOT (CMAKE_SYSTEM_NAME MATCHES "OpenBSD")) find_package_static(Libunwind 1.4.0 REQUIRED) prefer_static_libs() find_library(LZMA_LIBRARY lzma) diff --git a/rts/Game/LoadScreen.cpp b/rts/Game/LoadScreen.cpp index e2a9b7e6b99..b634b49b19e 100644 --- a/rts/Game/LoadScreen.cpp +++ b/rts/Game/LoadScreen.cpp @@ -136,7 +136,11 @@ bool CLoadScreen::Init() // the global font), the latter will cause problems in GL4 { auto lock = CLoadLock::GetUniqueLock();

CMake: SDL2, libunwind, GLAD, OpenAL EFX, linker warnings - FindSDL2.cmake: Add parent directory to include path so #include works with macOS SDL2 config (which sets include to /include/SDL2 directly) - FindLibunwind.cmake: Use INTERFACE IMPORTED library target on macOS (fixes -framework treated as file path by Unix Makefiles generator) - glad/CMakeLists.txt: Exclude glad_glx.c on Apple (no GLX on macOS) - legacy/headless CMakeLists.txt: Suppress -no_warn_duplicate_libraries on macOS (benign transitive dependency duplicates) - include/AL/: Vendored OpenAL EFX headers (macOS OpenAL.framework has no EFX support; needed for sound system compilation) --- include/AL/alext.h | 51 ++++++++++ include/AL/efx.h | 149 ++++++++++++++++++++++++++++ rts/build/cmake/FindLibunwind.cmake | 25 +++--

Guard GetTexID() / DisOwnTexture() to no-op on a null atlasTex so a failed atlas degrades gracefully instead of crashing.

Mesa's surfaceless EGL platform doesn't expose window-bit configs; presentation happens via CAMetalLayer + KosmicKrisp WSI (Vulkan -> Metal). 3. EGL: walk OpenGL versions 4.6 -> 3.2 calling eglCreateContext with CORE profile, take the first that succeeds. Mesa/Zink rejects both empty attribs (returns default GL 2.1 which the engine then rejects) and (3.0 + CORE) since profile attrs only apply to 3.2+. 4. EGL: dump renderer/version/vendor/GLSL strings right after eglMakeCurrent to make Zink-on-KosmicKrisp issues visible. The matching change to skip the legacy ARB extension-name check in CheckGLExtensions on a CORE-profile context was landed in an earlier commit on this branch. Required runtime env: EGL_PLATFORM=surfaceless MESA_LOADER_DRIVER_OVERRIDE=zink GALLIUM_DRIVER=zink MESA_GL_VERSION_OVERRIDE=4.6 MESA_GLSL_VERSION_OVERRIDE=460 VK_ICD_FILENAMES=/share/vulkan/icd.d/kosmickrisp_mesa_icd.aarch64.json DYLD_LIBRARY_PATH=/lib Result: GL 4.6 (Core Profile) Mesa 26.2.0-devel, renderer 'zink Vulkan 1.3(Apple M4 (MESA_KOSMICKRISP))', GLSL 4.60.

Add a manual present: read the rendered framebuffer back (glReadPixels, BGRA8) and blit it onto the window's CAMetalLayer drawable via Metal, then present. - rts/System/Platform/Mac/MetalPresent.{h,mm}: MRC-safe Metal helper. MacMetalPresent_Init(layer) sets up MTLDevice/queue and configures the CAMetalLayer (BGRA8, framebufferOnly=NO). MacMetalPresent_PresentBGRA() uploads a CPU BGRA buffer to a staging texture, blits it into nextDrawable, presents, commits. Optional vertical flip for GL bottom-up readback. - System/CMakeLists.txt: build MetalPresent.mm in the Mac platform sources. - builds/legacy/CMakeLists.txt: link Metal + QuartzCore frameworks on Apple. - GlobalRendering.cpp: stash the CAMetalLayer (g_metalLayer); SPRING_MAC_PRESENT_TEST now drives the flash through this path. Confirmed: the window shows the rendered clear color (red) instead of staying white -- the present mechanism works end to end (GL/Zink -> KosmicKrisp -> glReadPixels -> Metal -> window). Next: wire MacMetalPresent_PresentBGRA into CGlobalRendering::SwapBuffers (with flipY) so real frames present, and successively fix the load-time crashes (CProjectileDrawer atlas, etc.) to reach the draw loop. The glReadPixels roundtrip is a stopgap; IOSurface GL/Metal interop is the perf follow-up. --- rts/Rendering/GlobalRendering.cpp | 30 ++++++++ rts/System/CMakeLists.txt | 1 + rts/System/Platform/Mac/MetalPresent.h | 30 ++++++++ rts/System/Platform/Mac/MetalPresent.mm | 99 +++++++++++++++++++++++++ rts/builds/legacy/CMakeLists.txt | 5 ++ 5 files changed, 165 insertions(+) create mode 100644 rts/System/Platform/Mac/MetalPresent.h create mode 100644 rts/System/Platform/Mac/MetalPresent.mm diff --git a/rts/Rendering/GlobalRendering.cpp b/rts/Rendering/GlobalRendering.cpp index d3993ad522e..bf14372c8cf 100644 --- a/rts/Rendering/GlobalRendering.cpp +++ b/rts/Rendering/GlobalRendering.cpp @@ -13,10 +13,12 @@ #include #include #include +#include "System/Platform/Mac/MetalPresent.h" static EGLDisplay g_eglDisplay = EGL_NO_DISPLAY; static EGLContext g_eglContext = EGL_NO_CONTEXT; static EGLSurface g_eglSurface = EGL_NO_SURFACE; +static void* g_metalLayer = nullptr; // CAMetalLayer attached to the window's NSView static void* GetNSViewFromSDLWindow(SDL_Window* window) { SDL_SysWMinfo info; @@ -106,6 +108,7 @@ static bool InitEGLContext(SDL_Window* window, int major, int minor) { return false; void* nativeView = GetNSViewFromSDLWindow(window); + g_metalLayer = nativeView; // CAMetalLayer for the manual present path if (nativeView) { g_eglSurface = eglCreateWindowSurface(g_eglDisplay, eglConfig, (EGLNativeWindowType)nativeView, NULL); } @@ -791,6 +794,33 @@ bool CGlobalRendering::CreateWindowAndContext(const char* title) #endif #endif +#if defined(__APPLE__) && !defined(HEADLESS) + // Tracer bullet: when SPRING_MAC_PRESENT_TEST is set, flash the window + // red/blue for ~8s by rendering a clear and presenting it to the window's + // CAMetalLayer via the manual Metal present path (glReadPixels -> MTLTexture + // -> blit to drawable).

The engine writes glReadPixels output directly into the IOSurface's CPU view (honoring its rowBytes via GL_PACK_ROW_LENGTH), and a one-triangle Metal render pass samples the same surface and Y-flips into the drawable. Adds: - MacMetalPresent_AcquireIOSurfaceBuffer(w, h, &rowBytes) returns a locked CPU pointer also bound as an MTLTexture; recreates the backing only when dimensions change. - MacMetalPresent_PresentIOSurface(flipY) unlocks the surface, encodes a cached render pipeline state (flip / non-flip), and presents the drawable. - IOSurface.framework added to the legacy build's link list. The original MacMetalPresent_PresentBGRA is kept for the early-splash callsite, and as a runtime fallback selectable via SPRING_MAC_LEGACY_PRESENT=1. Notes: - Apple Silicon's IOSurface picks 64-pixel row alignment, so at width 2940 rowBytes is 11776 (= 2944 pixels per row, 4 pixels of padding). Honor it via GL_PACK_ROW_LENGTH or the readback tears. - Logs '[MetalPresent] IOSurface zero-copy path active (WxH, rowBytes=N)' once on first acquire, and a corresponding 'LEGACY CPU-staging path active' line if the fallback is taken. --- rts/Rendering/GlobalRendering.cpp | 93 +++++++--- rts/System/Platform/Mac/MetalPresent.h | 14 ++ rts/System/Platform/Mac/MetalPresent.mm | 222 ++++++++++++++++++++++++ rts/builds/legacy/CMakeLists.txt | 8 +- 4 files changed, 313 insertions(+), 24 deletions(-) diff --git a/rts/Rendering/GlobalRendering.cpp b/rts/Rendering/GlobalRendering.cpp index 41a9ec24335..28e86ddc526 100644 --- a/rts/Rendering/GlobalRendering.cpp +++ b/rts/Rendering/GlobalRendering.cpp @@ -993,30 +993,81 @@ void CGlobalRendering::SwapBuffers(bool allowSwapBuffers, bool clearErrors) if (g_eglDisplay != EGL_NO_DISPLAY && g_eglSurface != EGL_NO_SURFACE) { // eglSwapBuffers on the (surfaceless) pbuffer presents nowhere, so // read the rendered default framebuffer back and blit it onto the - // window's CAMetalLayer via Metal. glReadPixels also syncs, so the - // frame is complete. flipY: GL readback is bottom-up. - const size_t need = static_cast(g_pbufW) * g_pbufH * 4; - if (g_presentBuf.size() < need) - g_presentBuf.resize(need); - glReadPixels(0, 0, g_pbufW, g_pbufH, GL_BGRA, GL_UNSIGNED_BYTE, g_presentBuf.data()); - // Debug: dump rendered frames to raw files for inspection without - // screen capture.

Several Lua-built shaders in BAR rely on those legacy paths, so the compat profile is the easier integration point on the macOS path. Geometry shaders remain unavailable regardless of profile because Vulkan reports geometryShader=false on Metal; that is a separate problem and not affected by this change. --- rts/Rendering/GlobalRendering.cpp | 42 ++++++++++++++++++++++++++++--- 1 file changed, 38 insertions(+), 4 deletions(-) diff --git a/rts/Rendering/GlobalRendering.cpp b/rts/Rendering/GlobalRendering.cpp index 5268e29d920..d2a83c0812a 100644 --- a/rts/Rendering/GlobalRendering.cpp +++ b/rts/Rendering/GlobalRendering.cpp @@ -166,13 +166,45 @@ static bool InitEGLContext(SDL_Window* window, int major, int minor) { fprintf(stderr, "[EGL] Config: renderable=0x%x surfaceType=0x%x conformant=0x%x (OPENGL_BIT=0x%x)\n", cfgRenderable, cfgSurface, cfgConformant, EGL_OPENGL_BIT); } - // Walk down from the highest core-profile version Zink might support. - // KosmicKrisp reports Vulkan 1.3 / MoltenVK-parity, so 4.6 -> 3.3 should - // cover Zink's GL exposure.

Apple Silicon cores are heterogeneous: a small high-performance (P) cluster and a larger efficiency (E) cluster. Treating every visible core as a P-core (the previous behavior) caused the engine to over-provision sim worker threads, some of which then landed on E-cores at ~1/3 the throughput of P-cores. Two changes: 1. CpuTopology::GetProcessorMasks now reads the per-perflevel sysctl keys (hw.perflevel0.physicalcpu, hw.perflevel1.physicalcpu) to count P-cores and E-cores separately, and reports them in the appropriate masks. Intel Macs and older kernels do not expose perflevel keys, so behavior on those targets is unchanged (all cores treated as P). On an Apple M4 (4 P + 6 E) the new masks read: Performance Core Mask: 0x0000000f Efficiency Core Mask: 0x000003f0 and Optimal thread count drops from 9 to 4, matching the P-cluster. 2. ThreadSupport::SetupCurrentThreadControls now calls pthread_set_qos_class_self_np(QOS_CLASS_USER_INTERACTIVE, 0) so the kernel preferentially schedules these threads on the P-cluster. The call is gated to threads that pass through ThreadStart with a ThreadControls handle (the sim workers), not every pthread in the process, so background I/O / helper threads remain free to land on the E-cluster. --- rts/System/Platform/Mac/CpuTopology.cpp | 57 +++++++++++++++++++---- rts/System/Platform/Mac/ThreadSupport.cpp | 11 +++++ 2 files changed, 59 insertions(+), 9 deletions(-) diff --git a/rts/System/Platform/Mac/CpuTopology.cpp b/rts/System/Platform/Mac/CpuTopology.cpp index e1f3a61c255..8b027fee25d 100644 --- a/rts/System/Platform/Mac/CpuTopology.cpp +++ b/rts/System/Platform/Mac/CpuTopology.cpp @@ -4,21 +4,60 @@ namespace cpu_topology { +namespace { + +// Read an unsigned sysctl value by name.
