During March 2026, this developer enhanced the tianocore/edk2 repository by implementing ACPI 6.6 NUMA extensions to support richer memory affinity and cache configuration across platforms. The work focused on extending the SRAT and HMAT structures, adding a specific-purpose flag and an address mode field to improve NUMA configuration and platform interoperability. Leveraging expertise in ACPI specifications, firmware development, and system programming with C, the developer contributed changes to the MdePkg/IndustryStandard package. This update enables more granular performance tuning and cross-platform support for NUMA systems, reflecting a deep understanding of low-level system architecture and collaborative firmware engineering.
