 ## Contributing

 Testing games and submitting detailed bug reports are useful ways to contribute. Search existing
 issues first, then use the **Game Emulation Bug Report** template and attach the complete log file.

-Code contributions should be focused, build successfully on Windows, and include relevant tests
-where practical. Because KytyPS5 is still evolving quickly, consider opening an issue before
+Code contributions should be focused, build successfully on the platforms they touch, and include
+relevant tests where practical. Windows is the primary target, so a change that alters shared code
+should not regress it; changes confined to a platform's own code paths only need to build there. Because KytyPS5 is still evolving quickly, consider opening an issue before
 starting a large change.

+### Building on Linux
+
+Install the toolchain and the libraries the bundled SDL2 needs. Without the audio, Wayland and
+udev development packages SDL2 quietly configures itself without those backends, and the resulting
+build has no working sound and no gamepad hotplug:
+
+```bash
+sudo apt-get install --no-install-recommends \
+  clang lld ninja-build cmake git glslang-tools \
+  libgl1-mesa-dev libx11-dev libxcursor-dev libxext-dev libxfixes-dev \
+  libxi-dev libxrandr-dev libxss-dev libxkbcommon-dev \
+  libasound2-dev libpulse-dev libudev-dev libdbus-1-dev libwayland-dev wayland-protocols
+```
+
+Qt 6 (Concurrent, Network, Widgets) is also required — either the distribution packages
+(`qt6-base-dev`) or an official Qt installation.
+
+```bash
+git submodule update --init --recursive
+
+cmake -S src -B _Build/linux -G Ninja -DCMAKE_BUILD_TYPE=Release \
+  -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ \
+  -DCMAKE_PREFIX_PATH="$Qt6_DIR"
+
+cmake --build _Build/linux --target launcher --parallel
+cmake --install _Build/linux --prefix _Build/linux/install
+```
+
+The install step copies the Qt libraries and plugins next to the binaries, so
+`_Build/linux/install` runs without a matching system Qt.
+
+As on Windows, the MSVC compiler is not used; Clang is required. `cl.exe` is rejected at configure
+time.
+
+Note that the CMake source root is `src`, not the repository root.
+
 ### Visual Studio Code

 A ready-made Visual Studio Code setup is included in [`.vscode`](.vscode). It configures CMake
 Tools to build the project with Ninja and `clang-cl` and provides launch profiles for both
-`launcher.exe` and `kyty_emulator.exe`.

ClaxtenandGitHub	e91dd39cb0	Drop redundant PROT_NONE tracking in reserve paths for Linux (#122 ) src: platform: Linux: Drop redundant PROT_NONE tracking in reserve paths * Some UE4 games, such as The Pathless, reserve a 512 GiB virtual address range during libc startup. Tracking every 4 KiB page causes a long delay and is unnecessary since the range is already PROT_NONE, and untracked pages are treated as NoAccess.

M. Abdullah GitHub nmzik	4d79f19089	macOS (Apple Silicon) support: native build running under Rosetta 2 with MoltenVK (#102 ) * macos: POSIX platform layer (host fault handler, virtual memory) - hostException: Mach/POSIX signal-based host fault handler mirroring the Windows vectored handler (SIGSEGV/SIGBUS/SIGILL), behind '#elif defined(__APPLE__)'. Windows and Linux branches are untouched. - sysLinuxVirtual: mach_vm_region-based is_mapped (no /proc/self/maps on macOS), PTHREAD_MUTEX_NORMAL, and a MAP_FIXED carve-in-place allocator that never leaves an unmapped hole for dyld/Rosetta/Metal to claim. All __APPLE__-guarded; the original Linux allocator path is preserved verbatim. - sysLinuxDbg/sysLinuxFileIO: libgen.h for basename(), and a POSIX opendir/readdir implementation of SysFileGetDents (previously a stub). * macos: guest kernel backing, threads, and POSIX libs - memory/memoryAddressSpace: anonymous shm_open backing (macOS has no memfd_create) and re-reserve-on-unmap so a guest MAP_FIXED remap never destroys a host mapping (__APPLE__-guarded). Drops host <sys/mman.h> MAP_* macros so the guest's constexpr MAP_* constants compile (no-op on Windows). - pthread: undef the host PTHREAD_STACK_MIN macro; on non-Windows, pin the stack-switch asm's guest rsp/rbp to callee-saved r14/r15 (the template clobbers r12/r13); __APPLE__ no-op for the absent pthread_condattr_setclock. The Windows stack-switch asm is byte-identical. - network: define SOCKET/INVALID_SOCKET for the non-Windows paths (were undefined at 20+ use sites), and rename the non-Windows kernel_clock_* helpers to the CamelCase names the callers already use. Both repair the shared non-Windows build. Integer reinterpret_cast -> static_cast. * loader: pin stack-switch asm operands to callee-saved registers RunEntry switches to the guest stack with an asm template that clobbers r12/r13 before consuming its inputs. With plain "r" constraints the compiler may place func/guest_rsp/guest_rbp into r12/r13, so 'callq func' jumps through the saved host rsp -- a latent miscompile on every platform that any unrelated codegen change can trigger. Pin the inputs to rbx/r14/r15, which the template never touches and the SysV callee preserves. General correctness fix (not macOS-specific); the same fix is applied to pthread RunOnGuestStack. macos: Vulkan/MoltenVK graphics enablement - pageManager: GPU write-tracking via Mach VM queries + mprotect (mprotect cannot report the previous protection, so the expected-old check is dropped), thread id via pthread_mach_thread_np, 4 KB page-size check -- __APPLE__-guarded. - shaders/renderDraw/vulkanWindow: MoltenVK lacks VK_EXT_color_write_enable, VK_EXT_depth_clip_enable and depthBounds; fall back to static color-write masks and default depth clipping, request VK_KHR_portability_subset, and reuse the graphics queue for present when only one queue is exposed. Non-Apple pipeline/extension setup is unchanged. - window: optional borderless window (KYTY_BORDERLESS) to sidestep a Rosetta NSException in macOS window chrome. * graphics: macOS thread identity for region tracking Region-ownership locks resolve the current thread via GetCurrentThreadId() on Windows and EXIT elsewhere. Use the Mach thread port on macOS (nonzero per-thread id; 0 stays the no-owner sentinel). * macos: marshal AppKit window operations to the main thread The present worker thread shows the window, updates its icon and title, and recreates a lost Vulkan surface. AppKit traps with 'Must only be used from the main thread' when these run off the main thread. Route them through a small task queue drained by the SDL main loop (an SDL_USEREVENT wakes the loop when it is blocked in SDL_WaitEvent). Title updates are fire-and-forget; showing the window and surface recreation wait for completion. Windows and Linux call the SDL functions directly, as before. * build: ignore the _Build output directory _Build is the conventional out-of-tree build location (only _Build/vscode-clang was ignored); a stray git add could sweep build artifacts into a commit. * macos: isolate stack-switch workaround --------- Co-authored-by: nmzik <Nmzik@mail.ru>	2026-07-28 19:03:15 +02:00

Abdullah K.andnmzik	31ea0081a9	perf: skip LOGF formatting when logging is silent Build KytyPS5 (Linux) / build (push) Waiting to run Details Build KytyPS5 / build (push) Waiting to run Details Build KytyPS5 / release (push) Blocked by required conditions Details LOGF/LOGF_COLOR always ran fmt::sprintf even when the output was discarded; at emulator log volume the formatting alone costs frames. Add Log::IsSilent() and short-circuit before formatting. Behavior-preserving on all platforms (it only skips work whose result is thrown away); before init it reports non-silent so early logs still print.

Abdullah K.andnmzik	7921269878	build: add macOS (Apple Silicon) build support macOS compiles the existing POSIX/Linux code paths (KYTY_PLATFORM_LINUX) targeting x86_64 under Rosetta 2. Adds an APPLE branch to the build: selects Apple's ld64 linker, unsets the Ninja response-file forcing (Apple ar has no @file support), derives the target arch from CMAKE_OSX_ARCHITECTURES for cpuinfo/ffmpeg, and re-signs the binary post-build with JIT entitlements (required to execute written trampolines and Rosetta-translated guest code). All changes are guarded by if(APPLE); Windows and Linux configuration is unchanged. (cherry picked from commit `13be13b757`)	2026-07-27 14:16:51 +02:00
