Worked on the microsoft/msquic repository to expand Linux io_uring support to ARM-based systems, focusing on enabling cross-architecture compatibility. The work involved removing an x86_64-specific guard in the msquic_posix.h file, allowing io_uring code paths to compile and run on aarch64. This change improved I/O efficiency and broadened deployment options for ARM servers, with production validation performed in Azure Kubernetes Service environments. The implementation was carried out in C, leveraging skills in Linux kernel development, network programming, and system programming. This feature laid the groundwork for future performance enhancements of io_uring on Linux for ARM platforms without introducing new bugs.
