Worked on stabilizing Vulkan buffer device address tracking in the LunarG/gfxreconstruct repository, focusing on improving buffer management during capture workflows. Addressed issues where multiple VkBuffer handles referenced the same device address by implementing targeted fixes in C++ to handle shared-address scenarios and adding guard checks to prevent incorrect removal of buffer mappings. Applied concurrency control techniques to reduce capture-time crashes and enhance the robustness of buffer management. These changes improved the correctness and reliability of Vulkan capture processes, ensuring that buffer mappings are maintained accurately when device addresses are shared, and contributed to a more stable developer experience.
