Worked on kernel-level stability and power management improvements for Linux graphics drivers, focusing on the analogdevicesinc/linux and geerlingguy/linux repositories. Addressed critical bugs in the DRM/XE OA path by implementing a runtime power management guard during OA stream release, ensuring proper acquisition and release of PM runtime references to prevent improper power state transitions. Enhanced driver reliability by replacing a potentially NULL-returning function with xe_root_mmio_gt, eliminating NULL pointer dereference risks during OA initialization. Utilized C programming, device driver development, and kernel power management expertise to deliver targeted, traceable fixes that improved hardware stability and reduced static analysis warnings in CI.
