Worked on the geerlingguy/linux repository to address stability issues in the DRM XE driver for Virtual Functions under SR-IOV. Focused on kernel development and GPU programming, the work involved implementing a targeted fix for unrecoverable faults caused by skipped TLB invalidations. By reintroducing proper TLB flushing and adding VF-specific handling in C, the patch improved the reliability and stability of VF operations in virtualization workloads. The solution was delivered as a focused patch series, ensuring that VF devices maintain integrity and resilience in production SR-IOV environments, ultimately enhancing system uptime and input/output stability for virtualized deployments.
