3 Commits • 1 Features
Jan 1, 2026January 2026 focused on delivering upstream-ready PPC Qoriq/mpc85xx platform enhancements and stabilizing CI. Key items include moving the patch from mpc85xx to generic/pending to enable upstream patching and improving failsafe reliability by aligning preinit with the primary LAN/first DSA port. Fixed build CI issues by correcting T4240RDB u-boot variant selection to prevent buildbot crashes and rootfs installation problems. Overall impact: higher upstream readiness, reduced CI instability, and improved platform reliability across Qoriq targets. Technologies demonstrated include kernel patching, upstream processes, mpc85xx, u-boot, patch management, and CI optimization.

Dec 1, 2025December 2025 monthly summary for DragonBluep/openwrt. Focused on enabling the internal Curve25519 cryptographic library for the Qoriq target, and cleaning up unused kernel configurations to improve security posture and maintainability. Despite a lean feature set this month, the work establishes a stronger cryptographic baseline for Qoriq-based OpenWrt devices and reduces reliance on external crypto libraries. No major bugs were reported this period. The work lays the groundwork for faster cryptographic operations and easier kernel maintenance going into 2026.

Jul 1, 2025July 2025 — DragonBluep/openwrt monthly performance snapshot. Focused on stabilizing and future-proofing the Kirkwood target by refreshing the kernel configuration to kernel 6.12 and updating the related build configuration. The change ensures CONFIG_FRAMER is not set and aligns the kernel build with a newer baseline, reducing build risks and enabling security/feature updates on Kirkwood devices.
