Worked on kernel-level virtualization within the geerlingguy/linux repository, focusing on refining KVM and TDX integration. Addressed a critical issue by removing TDVMCALLINFO_GET_QUOTE reporting from userspace, ensuring alignment with the GHCI base specification and resolving ambiguity in exposed TDVMCalls. This change improved consistency between kernel and userspace interfaces and freed up resources for future TDVMCalls, enhancing maintainability. The work involved deep system programming and kernel development using C, with an emphasis on virtualization technologies. By clarifying the handling of TDVMCALLINFO, the codebase was prepared for upcoming features and maintained compliance with evolving virtualization standards.
