Worked on stabilizing LoongArch virtualization and UEFI boot processes across the espressif/qemu, tianocore/edk2-platforms, and geerlingguy/linux repositories, focusing on kernel-level bug fixes and system integration. Addressed test hangs in Loongarch64 VM UEFI tests by updating kernel, initrd, and BIOS assets, and improved test automation reliability using C and Python. Enhanced UEFI boot stability for LoongArch QEMU by correcting function arguments and adjusting configuration files, ensuring smoother platform validation. Optimized CPU hotplug resource management in LoongArch virtual machines by implementing hooks to close timers and clear interrupts, reducing unnecessary CPU usage and improving host efficiency.
