February 2026 monthly summary for sched-ext/scx focusing on delivering per-task data sharing and improved hinting efficiency through a new Task Local Data Library (TLD). The work introduces APIs to create and access per-task data, an abstract storage layer on top of task local storage, and a key-value API to hide storage layout from both user space and BPF programs. This lays the groundwork for easier thread-specific hint management and faster hint lookup, aligning with our performance and developer productivity goals. The commit anchoring this work is 4dd6a2dfa83e4fc06435b36f340ee578b93b5817, which includes the TLD integration and accompanying user-space API changes.

Month 2025-10 for linux-riscv/linux focused on improving RX path correctness and stability in high-throughput networking. Primary deliverable: a critical bug fix to ensure skb construction from XDP-modified buffers is based on the final xdp_buff state after XDP program execution, preventing incorrect skb generation and issues with skb truesize and fragments in mlx5e and mlx5 drivers. This work enhances packet correctness and reliability under heavy load in mlx5-based NICs. Key techniques demonstrated include kernel networking internals, XDP/XDP_BUFF handling, and mlx5 driver RX path fixes.

September 2025 performance summary for linux-riscv/linux focused on strengthening the XDP/BPF path through end-to-end data handling improvements, packet pointer integrity fixes, and expanded verification. Delivered consolidated XDP data handling enhancements, robust fixes to pointer management after data modifications, and enhanced testing coverage with BTF integration and kfunc/selftest improvements. This work reduces production risk in high-throughput networking and improves maintainability via stronger tests.
