PROFILE
Neeraj Upadhyay
Neeraj Upadhyay developed Secure AVIC support for SEV-SNP guests in the torvalds/linux repository, focusing on robust APIC virtualization and secure guest interaction. He implemented a dedicated AVIC driver in C, handling APIC backing page initialization, APIC ID setup, and vector management to enable advanced interrupt delivery. His work included support for IPI, NMI, LAPIC timer, and EOI handling, as well as MSR interception and enablement to enforce Secure AVIC policies. By advancing guest capability signaling and kexec readiness, Neeraj ensured production stability, demonstrating depth in kernel development, low-level programming, and x86 virtualization within a complex system architecture.
