October 2025 monthly summary for archlinuxcn/repo and felixonmars/archriscv-packages focusing on installer/packaging enhancements, build fixes, Meson migration, and RISC-V kernel configuration improvements. Delivered multiple commits across projects improving reliability, performance, and maintainability, with clear business value in deployment reliability, faster builds, and easier future maintenance.

September 2025 monthly summary for two primary repos: archlinuxcn/repo and amazonlinux/linux. The month focused on packaging modernization, reliability, and broader hardware support, delivering cross-repo improvements with measurable business value for maintenance and deployment pipelines. Key features delivered: - archlinuxcn/repo: Sdrangel-git Packaging and Build System Modernization — consolidated packaging, self-maintain mode, Ninja build, Qt6 migration (including added qt6-scxml dependency), and cleanup of optional dependencies. Also implemented dependency name fixes, repo_depends fixes, and a channel demodulation disable flag to avoid FTBFS. Notable commits include apkg setup for sdrangel-git and its dependencies; switches to self-maintain and Ninja; and the Qt6 upgrade. - archlinuxcn/repo: VKFFT Integration and Vulkan Packaging — enabled vkfftengine, added Vulkan packaging (vkfft-vulkan) and related toggles, expanding SDR workflow capabilities. - archlinuxcn/repo: Dependency hygiene and feature expansion — added missing qt5-gamepad, removed log4cpp, cleaned unused repo_depends, fixed dependency resolution, and enabled additional features in sdrangel-git. - archlinuxcn/repo: Packaging and ecosystem enhancements — added new packages (probe-rs, probe-rs-git, rtthost, otc-wenjinmincho font), updated descriptions, and refined build conditions to support broader hardware and applets. - amazonlinux/linux: gs_usb driver improvements — enhanced multi-channel CAN support by fixing channel identification and increasing the number of supported interfaces (from 3 to higher, now aligned with U8_MAX), enabling better interoperability with devices that expose many CAN channels. Major bugs fixed: - archlinuxcn/repo: Fixed dependency resolution issues and ensured newer vkfft dependencies and versions to prevent build failures. Fixed libsigmf usability, extension detection issues, and probe-rs packaging conflicts. Resolved Lilac.yaml issues and udev path fixes for probe-rs, along with tag-prefix normalization when handling probe-rs versions. - archlinuxcn/repo: Cleaned and trimmed packaging dependencies (e.g., removing unused optdepends and log4cpp) to reduce maintenance surface and FTBFS risk. Resolved missing git dependencies for probe-rs-git and other packaging-related conflicts. - amazonlinux/linux: Improved stability of gs_usb CAN support via channel handling fixes and interface cap adjustments, reducing misidentification of channels and improving device compatibility. Overall impact and accomplishments: - Increased packaging stability, scalability, and platform coverage across two major repos, enabling broader hardware support, more features, and easier maintenance workflows. - Established a more robust build pipeline with modern tooling (Ninja, Qt6) and forward-looking dependencies (VKFFT, Vulkan) to support current and future SDR capabilities. - Reduced FTBFS surface area and dependency-related failures, improving release readiness and downstream adoption. Technologies/skills demonstrated: - Packaging engineering and release automation across Arch and Amazon Linux ecosystems. - Modern build toolchains (Ninja), Qt6 migration, and Vulkan/VKFFT integration. - Dependency hygiene, conditional packaging, and cross-repo coordination for probe-rs and related projects. - Hardware-software integration considerations (gs_usb multi-channel CAN support) and improved device interoperability.

Month: 2025-08. Focused on expanding RISC-V hardware compatibility and driver support in felixonmars/archriscv-packages. Implemented kernel configuration updates and driver coverage enhancements for TH1520 AON, SG2042/2044, and Spacemit K1, aligning with roadmap to broader hardware readiness and easier deployment.

Monthly work summary for 2025-04 focusing on kernel configuration updates in the felixonmars/archriscv-packages repository to support riscv64 hardware (Spacemit K1 and Microchip IPC SBI).

March 2025 monthly summary for felixonmars/archriscv-packages. Delivered kernel configuration updates to extend RISCV hardware support by enabling new drivers for TH1520, K230, and K1 on riscv64. This work aligns with Linux kernel 6.13.6.arch1 and improves hardware compatibility and potential performance on supported RISC-V platforms. No major bugs reported or fixed this month; focus was on feature delivery and patch reliability for upstream and downstream builds. The work reduces integration risk for customers using these boards and positions the project for smoother adoption of future kernel updates.

January 2025: Major kernel and hardware support upgrade in felixonmars/archriscv-packages. Delivered a Linux kernel upgrade to 6.12.10.arch1 with Sophgo device drivers and JH7110 SPI support, and removed a Fortify patch to resolve early-boot compatibility issues. This work enhances hardware support, improves boot reliability, and reduces ongoing patch maintenance. Commit reference: 03effabe80dc00ef1a7c67f1df1ea2ce5cc95af7.
