Worked on the utmapp/gfxstream repository to enhance cross-platform graphics emulation by implementing a cross-platform UdmabufCreator abstraction and integrating it with the Vulkan decoder, enabling host-visible memory allocation as udmabuf on Linux and conditionally on Android. Addressed stability and compatibility by gating emulator-specific Vulkan operations and correcting X11 memory export logic, reducing configuration-related crashes. Improved memory management and host-guest sharing robustness through refined memfd handling and alignment for KVM. Centralized Meson build configuration and standardized header usage, resolving build-time segfaults and compile errors. Utilized C, C++, and Meson, focusing on system programming, memory management, and build system configuration.
