PROFILE
Jason Xu
Jason contributed to the NVIDIA/edk2-platforms repository by standardizing RISC-V platform library usage and enhancing Flattened Device Tree (FDT) compatibility. He updated FdtLib usage and paths, integrated essential TimerLib support, and realigned platform descriptor files to the BaseFdtLib implementation, ensuring reliable FDT processing and timer services during early boot in the PEI_CORE phase. His work included updating the SiFive U540 DSC to utilize the new FdtLib, reducing fragmentation across RISC-V platforms. Using C and leveraging expertise in embedded systems and firmware development, Jason’s focused engineering improved boot reliability and established a scalable foundation for future RISC-V platform support.

Jul 1, 2025For 2025-07, delivered key upgrades to the NVIDIA/edk2-platforms project focused on RISC-V platform library standardization and FDT compatibility, enabling reliable boot and cross-board consistency. The work standardized library usage and FDT handling across RISC-V platforms, updated FdtLib usage/paths, and added essential TimerLib to support early boot through the PEI_CORE phase. SiFive U540 DSC was updated to utilize the new FdtLib, and platform descriptor files were aligned to the BaseFdtLib implementation to ensure correct Flattened Device Tree processing and timer services during early boot. The changes reduce fragmentation, improve boot reliability, and lay groundwork for scalable RISC-V platform support.
