PROFILE
Mariam Elshakfy
Worked on NVIDIA/edk2-platforms to deliver foundational platform enablement and maintenance for embedded systems, focusing on Xilinx and ZynqMP support. Developed and documented EDK-II porting guides, implemented initial package configurations, and migrated the MMC driver to SdMmcPciHcDxe, improving cross-SoC compatibility and maintainability. Addressed platform stability by adjusting stack sizing, refining platform configuration, and resolving memory conflicts between TF-A and UEFI. Contributed to repository governance by updating CODEOWNERS and maintainership documentation. Utilized C, Assembly, and Markdown to deliver features and fixes, demonstrating skills in firmware development, driver integration, documentation, and embedded systems engineering across multiple platform layers.

Jul 1, 2025For 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.

May 1, 2025In 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.

Oct 1, 2024October 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.
