Every std::mutex, lock_guard, unique_lock, scoped_lock, condition_variable, call_once and semaphore left in Source/Core is replaced by a lock-free design: - Input: the device list, control bindings, stick calibration and default device are published snapshots read under a quiesce; a rebind requested while another thread is rebinding is handed to that thread instead of waited for. - WiimoteReal: the pool thread owns the slots and runs commands from an MPSC queue; the active Wiimotes are atomic slots. - EXI/SI/IOS devices: socket and packet traffic goes through SPSC rings or MPSC handoffs owned by one thread; USB scanning publishes its device list, and libusb transfers drain through a CallGate. - Memory cards: the flush thread applies change records queued by the CPU thread. - Custom assets: loads are scheduled as a published batch with an atomic cursor, results come back over an MPSC stack, and busy assets are skipped and retried. - D3D state and GL program caches use insert-only atomic maps (Common/AtomicHashMap.h). - Logging appends with O_APPEND / FILE_APPEND_DATA; FatFs reports busy instead of waiting; per-socket WSAStartup/WSACleanup. Deleted as unused by the libretro core: the profiler, the FIFO recorder, the volume verifier, the touch InputOverrider and the GameCube adapter's libusb path.
