Mariam Elshakfy contributed to NVIDIA/edk2-platforms by developing and stabilizing embedded firmware features for Xilinx platforms. She authored a comprehensive EDK-II porting and build guide, enabling reproducible platform ports and improving onboarding. Her work included migrating the MMC driver to SdMmcPciHcDxe, implementing platform initialization for non-discoverable PCI devices, and refining platform configuration to resolve memory conflicts during boot. Mariam also established initial package configurations and updated governance for Xilinx support, demonstrating skills in C, Assembly, and UEFI. Her engineering addressed maintainability, cross-platform compatibility, and documentation, reflecting a deep understanding of embedded systems and repository management.

For 2025-07, NVIDIA/edk2-platforms delivered a focused TF-A configuration fix in ZynqMp VirtualPkg. TF-A was previously placed in DRAM, creating memory conflicts with UEFI and requiring DRAM reservation. The TF-A stage is now correctly placed in On-Chip Memory (OCM), eliminating the need to reserve DRAM and simplifying the example configuration. This change stabilizes boot, reduces memory pressure, and improves maintainability across configurations.

In May 2025, completed MMC subsystem migration in NVIDIA/edk2-platforms: migrated MMC driver from SDHCI to SdMmcPciHcDxe and added a platform initialization driver to register the MMC device as a non-discoverable PCI device. Removed legacy MMC driver and references to finish the migration, reducing maintenance burden and potential compatibility issues across platforms. Commit: 13e4eb768979719ec94069501ddb8c2a4a253ded.

October 2024 focused on enabling ZynqMP-based platform porting within NVIDIA/edk2-platforms by delivering a comprehensive EDK-II porting and build guide. The README documents the end-to-end process to port EDK-II to ZynqMP-based platforms, including how to create a new platform, configure and create description files, assemble required components, and perform builds. This work was implemented via a single commit that adds a package README, providing a stable, reusable blueprint for future ports. Impact includes reduced porting time, improved onboarding, and stronger build reproducibility across teams. Tech skills demonstrated include EDK-II porting, platform description management, documentation, and cross-team collaboration.
