Extending LLDB to Debug Applications That Span CPUs and GPUs

Meta has introduced a vendor-neutral accelerator plugin architecture for lldb-server that enables debugging across both CPUs and GPUs. By decoupling shared debugging infrastructure from hardware-specific controls, the system allows developers to treat CPUs and GPUs as distinct processes while maintaining a unified interface. This approach simplifies the development of complex heterogeneous applications, offering a standardized way to monitor performance and identify errors in code that shifts tasks between different processing units.
