Phoebe Chen contributed to the iree-org/iree repository by addressing a compatibility issue in the Benchmark submodule related to RISC-V timing measurements. She updated the timing mechanism to use the RDTIME instruction instead of RDCYCLE, adapting to changes in Linux kernel 6.6 where RDCYCLE became a privileged instruction. This fix ensured that third-party benchmarking tools continued to function reliably and that continuous integration processes remained stable. Phoebe applied her expertise in embedded systems, RISC-V architecture, and system programming, demonstrating a strong understanding of kernel APIs and cross-team integration to maintain accurate performance measurements across diverse environments.
