Thread List

Threads

These are the threads of a running ReXGlue program, by the name a debugger or profiler shows. See App Lifecycle for the UI thread and Kernel Services for guest threads.

Thread	Purpose	Lifetime
UI thread	Runs every TitleApp step and hook, the window and its event loop.	The thread that calls App::Init, usually the main thread of the process.
Main XThread	Runs the entry point of the title.	Starts in TitleRuntime::Launch and stops when the title unloads.
XThread and a hex ID, such as XThread000A	Runs a thread that the title creates. A thread that the title names shows its own name.	Starts in ExCreateThread and stops when the thread exits or the title unloads.
Title Monitor	Reports a normal exit when the main thread returns.	Starts in TitleRuntime::Launch and stops in TitleRuntime::Unload.
Kernel Dispatch	Runs deferred overlapped completions and queued DPCs.	Starts when TitleRuntime::Load loads the executable and stops when the title unloads.
GPU Commands	Runs the command processor, which reads the commands the title writes for the GPU.	Starts when TitleRuntime::Launch attaches the title to a Xenos graphics driver and stops when the title detaches.
GPU VSync	Raises the vertical blank interrupt at the refresh rate.	The same as GPU Commands.
Audio Worker	Calls the audio callbacks of the title.	Starts when TitleRuntime::Launch starts guest audio and stops when the title unloads.
XMA Decoder	Decodes XMA audio.	Starts and stops with Audio Worker.
rex::platform::TimerQueue	Fires guest timers. The process has one.	Starts with the first timer and stops in rex::Stop, which App::Shutdown calls.
DXGI UI Tick	Ticks the UI of the presenter. Windows only.	Starts when the presenter is set up and stops when it shuts down.
The spdlog flush thread, with no name	Flushes the log every log.flush_interval seconds.	Starts when the log file opens and stops when the logger session ends.
Shutdown Signals	Waits for SIGINT and SIGTERM. Linux and macOS only.	Starts in App::Init and stops in App::Shutdown.

The graphics driver modules start threads that build pipelines and translate shaders: D3D12 Pipelines, Vulkan Pipelines, Shader Translation, D3D12 Storage writer and Vulkan Storage writer.

On Windows, the system calls the console control handler for Ctrl+C and for closing the console window on a thread of its own.
