Jul 1, 2025July 2025 performance summary for AMDESE/linux-aspeed. Delivered substantial platform reliability and observability improvements across the board. Implemented Out-of-Band (OOB) Platform Reset/Provisioning (PPR) across Aspeed boards by updating DTS and enabling bmc_dev0, enabling boot-time PPR communication for Morocco, Nigeria, Kenya, and Ghana. Implemented a robust IPMID hang workaround to prevent BMC crashes during SBRMI DIMM reads. Fixed SBRMI DIMM temperature reporting to Celsius and to return 0 on error to avoid hangs. Enhanced PRB hardware for better thermal management and signal performance: GPIO-based fan control via updated DT, revised PRB fan driver, and increased I3C bus speed for APML across Kenya, Nigeria, and Ghana. Ghana-specific device-tree enhancements added System Voltage Regulators (VRs) and P1 VR I2C bus numbers to improve monitoring and control. Overall impact is improved remote manageability, stability under load, and a scalable foundation for expansion across regions.
