Sep 1, 2025

September 2025 achievements across two repositories focused on reliability, portability, and readiness for production use. Key features delivered include updating the Vkmark benchmark to 2025.01 in AOSC-Dev/aosc-os-abbs with corrected source tagging to point to the proper version, and adding TH1520 AON power-off/reboot support in linux-riscv/linux, including an auxiliary reboot device to facilitate communication during reset flows. Major bugs fixed include addressing a race condition in the Mesa LLVMPipe ORCJIT object cache access, improving stability and eliminating errors like MissingSymbolDefinitions. These efforts enhance benchmarking fidelity, system stability, and power-management capabilities, reducing risk in production deployments. Technically, this work demonstrates proficiency in kernel/driver development, cross-repo coordination, patch hygiene, and readiness for hardware-specific firmware interfacing.

June 2025: Delivered a kernel-level hardware support feature for AOSC-Dev/aosc-os-abbs by enabling built-in MMC BLOCK support and MTK regulator auto-load handling. This change makes MMC_BLOCK and MTK regulators built-in (commit 3a706cf56fa1596641b5849db5561034cdf19290), reducing device-specific workarounds and simplifying deployment on MTK-based architectures. Impact: improved cross-architecture hardware compatibility and reliability, fewer runtime issues related to regulator auto-loading, and smoother user experiences on affected devices. Technologies demonstrated: kernel configuration, build-time feature integration, cross-architecture validation, and improved regulator handling.
