PROFILE
Jacek Kolakowski
Over a two-month period, this developer enhanced PCIe device compatibility and platform configurability across the tianocore/edk2 and microsoft/mu_basecore repositories. They implemented dynamic Resizable BAR size constraints using C, enabling platforms to cap BAR sizes based on hardware capabilities and processor address width. Their work included removing deprecated PCIe configuration references, introducing new capability structures for Downstream Port Containment and Data Link Feature, and updating PASID definitions to align with PCIe 6.0 standards. Focusing on UEFI and embedded systems, they unified feature sets across repositories, improved standards compliance, and strengthened device interoperability without introducing any new bugs.

Nov 1, 2025Month 2025-11: PCIe and UEFI payload modernization across edk2 and mu_basecore. Key outcomes: 1) PCIe deprecation cleanup in edk2 removing PcdMrIovSupport per PCIe 6.0 (commits f078b8445a1135dac9137d74f49bef80bbcb1e77; 2e92a908e7595329d31f453e7144e90b42b6ea03); 2) PCIe capability enhancements introducing DPC and DLF structures and PASID updates (commit b65f97625aaa0d47f779aedcb834a41d6aa67593); 3) UEFI payload configurability with Resizable BAR max size parameter (commit bb943da707e14a0da6f9bb8e39834d5fd0edc731); 4) MU_BASECORE alignment of PCIe capabilities (DPC/DLF and PASID) via cherry-pick from MdePkg (commit 7134d0e81b9bab56082da05e8021a6d15b45bd59); Result: reduced legacy references, improved spec alignment, enhanced platform configurability, and strengthened device interoperability across the stack.
