Worked on the torvalds/linux repository, focusing on the DRM/Xe stack to enhance kernel stability and GPU virtualization readiness. Addressed a use-after-free issue by implementing a devm-managed release action, ensuring safe teardown of buffer objects before resource deallocation. Enabled CCS save and restore functionality for SR-IOV virtual functions, gated by GuC firmware version 70.48.0 or higher, and refactored the VF migration initialization to streamline workflows and improve maintainability. Utilized C programming and kernel development skills to deliver targeted improvements in device driver development, prioritizing resource lifecycle safety, compatibility, and performance for advanced virtualization features in the Linux kernel.
