This week's work advances on three fronts: kernel and bleedingedge alignment across Rockchip and Sunxi trees, board and platform enablement spanning RV1106 to SpacemiT, and CI hardening with self-hosted runner maintenance.

On the kernel side, bleedingedge was bumped to 7.1-rc3, accompanied by cfg80211 API fixes and re-enablement of the rtl8189fs and rtl8852bs drivers for the new release. Both the rockchip64 and sunxi patch stacks for current and edge were rewritten, an upstream ptrace fix for CVE-2026-46333 was backported to linux-rockchip, and the odroidxu4-current kernel moved to 6.6.139.

Platform enablement was broad. The Ayn Odin2 gained 7.0 kernel support, the Mekotronics R58X-Pro switched its vendor build to mainline U-Boot with a corrected LCD driver, and the H96 TV box advanced to U-Boot v2026.04. RV1106 transitioned from extlinux to a bootscript and gained DS1307, PCF85063, and RV8803 RTC drivers, while SpacemiT received OpenSBI, U-Boot, and BPI-F3 DTS fixups. Smaller but user-visible improvements include NanoPi M5 second USB3 port exposure via DRD0 host-mode pinning, NORCO EMB-3531 LPDDR4X variants, RK3528 USB2 PHY corrections for high-speed NCM, and UEFI x86 images enabling iwlwifi MLD and Intel SOF audio for MTL, LNL, and PTL.

Infrastructure work centered on self-hosted runner reliability and supply-chain hygiene. A new runner-cleanup module provides hourly disk and memory maintenance, skips busy runners, and ships via .deb, while a maintenance watchdog was added to the SDK repository. Multiple StepSecurity hardening passes landed across build and SDK workflows, though an overly strict egress-policy was subsequently reverted after breaking builds.
