PROFILE
Philip Yang
Over a three-month period, contributed to the ROCm/ROCR-Runtime and qualcomm-linux/kernel-topics repositories by developing robust test coverage and addressing critical kernel driver issues. Built a UserQueueBufValidation test in C++ to validate queue creation and buffer management under error conditions, using test-driven development and process isolation to improve reliability. Enhanced error handling for GPU memory unmapping, ensuring memory is not prematurely freed and improving runtime stability. Addressed a deadlock in the AMD kernel driver by implementing a lock downgrade in mmap operations, strengthening concurrency and system reliability. Demonstrated expertise in C, C++, kernel development, memory management, and device driver testing.

Sep 1, 2025In September 2025, delivered a stabilization patch for the AMD kernel driver path amdkfd, addressing a deadlock during draining retry fault in svm_range_restore_pages. Implemented a lock downgrade from mmap write lock to a read lock to ensure proper lock release and prevent system hangs under AMD GPU workloads. The work is captured by commit 7574f30337e19045f03126b4c51f525b84e5049e (drm/amdkfd: Fix mmap write lock not release).
