Worked on the tianocore/edk2 repository to implement E820 Soft Reserved Memory support in OVMF firmware, enabling QEMU to expose Specific Purpose Memory for high-bandwidth memory and accelerator or GPU use cases. The approach involved extending the EFI memory type enumeration with SoftReserved and introducing HOB-based resource handling through PlatformAddHobCB, ensuring proper memory attribution in line with ACPI 6.4+ and Linux e820 soft-reserved semantics. Using C and leveraging expertise in firmware development, ACPI, and low-level programming, the work established a foundation for hardware-aware memory management and future device-driver interactions in virtualized environments without addressing bug fixes.

September 2025 monthly summary focusing on key accomplishments in tianocore/edk2: Delivered E820 Soft Reserved Memory support in OVMF firmware to expose Specific Purpose Memory (SPM) for high-bandwidth memory (HBM) and accelerators/GPUs. This included adding EFI_ACPI_MEMORY_TYPE SoftReserved and implementing Resource HOB creation via PlatformAddHobCB for proper memory attribution. Commit 4e90b65e7b7bf0c090d3bc5142a684acac56345f enforces the design changes and provides context for future HBMs/accelerator integrations. Overall, prepared the groundwork for hardware-aware memory management in QEMU guests, aligning with ACPI 6.4+ and Linux e820 soft-reserved semantics.
