Developed RIMT support for RISC-V IO mapping in the tianocore/edk2 repository, focusing on ACPI and UEFI environments. The work involved implementing new RIMT structures in MdePkg to align with ACPI 6.6 and RIMT v1.0 specifications, as well as creating a parser within ShellPkg/acpiview to enable parsing and tracing of RIMT tables. Validation was performed end-to-end on QEMU 10.1 with IOMMU enabled, ensuring correct table parsing and mapping workflows. The project was completed in C, leveraging expertise in embedded systems and system programming, and included documentation updates to support future RISC-V platform integration.

Sep 1, 2025In September 2025, delivered RIMT support for RISC-V IO mapping in ACPI/UEFI within the tianocore/edk2 project. Implemented new RIMT structures (MdePkg) and added an ACPI view library parser (ShellPkg/acpiview) to parse and trace RIMT tables in UEFI environments. Completed end-to-end validation on QEMU 10.1 with IOMMU enabled, confirming correct table parsing and mapping workflows. This work aligns with ACPI 6.6 and the RIMT v1.0 specification, and lays the groundwork for broader RISC-V IO mapping support on future platforms. No major bugs fixed this month; the focus was on feature delivery, quality gates, and spec alignment.
