Xenia Git (March 9, 2026)

Xenia Git (2026/03/09) is an experimental Xbox 360 emulator that currently does not run games. The latest changelog includes numerous fixes and improvements: addressing data races on XFile, enhancing thread safety for various objects, and resolving audio crashes during shutdown. It also implemented a fast mutex for Linux, improved signal handling, and optimized memory management to prevent buffer overflows. Other updates involve clarifying logs, adjusting thread behavior to match Windows semantics, and ensuring proper functioning of vsync on Linux. Overall, this update focuses on stability and performance enhancements, contributing to Xenia’s ongoing development.

Xenia Git (2026/03/09) has been compiled. Xenia is an experimental emulator for the Xbox 360, but it isn’t able to run games (yet).

Xenia Git Changelog:
* [Kernel] Resolved data race concerning XFile position
* [CPU/Thread] Initialize r[2] constant value, utilized solely by HV as far as I know
* [Kernel] Improvements in thread safety for xfile, xmutant, and xtimer objects
* [APU] Shift XmaContext::Block() to base class with RAII locking
* [XboxKrnl] Prevent host crashes on guest traps
* [APU] Address audio crashes during shutdown
* [Kernel] Clear object handles prior to release in ObjectTable::Reset
* [Kernel] Reduce excessive log output
* [Xboxkrnl] Eliminate devkit memory access assertion and substitute with warning
* [x64] Fix vector mask issues and include missing tests
* [x64/Debug] Rectify TrapDebugPrint to properly conclude string
* [CPU] Verify for null when retrieving machine code pointer
* [Posix] Fix DeallocFixed-related crashes and memory leaks
* [CPU/PPC] Introduce Linux workaround for fdiv instruction format
* [Linux] Create fast mutex similar to Windows version
* [Linux/Threading] Alter self-suspend to wait until resumed
* [Memory] Clean up shm files on Linux exit
* [Threads] Assure accurate RTTI/vtable generation for PosixWaitHandle
* [Posix Threading] Implement robust mutexes
* [Posix Threads] Transitioned condition variables from static to instance-specific members and replaced potentially deadlock-prone predicate-based WaitMultiple with polling using try_lock.
* [Threading] Enhancements to signal handler and self-suspension
* [Kernel] Confirm initialization of file mutex
* [Kernel] Align thread suspension for posix with Windows behavior
* [Kernel] Synchronize ReleaseSemaphore for Posix to match Windows behavior
* Address potential buffer overflow in posix memory management
* Prevent threads from attempting self-suspension on Linux
* [GPU] Ensure v-sync operates correctly on Linux.
* Fix menu hotkeys functionality on Linux
* [Kernel/XMP] Introduce title-specific file I/O hooks for XMP volume synchronization
* [Build] Integrated with CLion
* [Cmake] Filter configuration presets. This removes VS preset visibility on Linux
* [Base] Substitute CRITICAL_SECTION with SRWLOCK-based mutexes
* [Base] Utilize function-local static for global_mutex
* [Kernel] Return null on handle type mismatch instead of raising an assertion
