Over a two-month period, contributed to embedded systems and firmware development by expanding the PLDM command set in the NVIDIA/libpldm repository, aligning with DSP0248 v1.3.0 and DSP0240 v1.2.0 standards to support broader platform management operations. This work involved protocol implementation in C and C++, updating platform headers and introducing new command numbers for enhanced interoperability. Additionally, addressed a critical compatibility issue in NVIDIA/dbus-sensors by updating the MCTPPreactor to support MCTP D-Bus API v2.0, ensuring reliable system communication. The approach emphasized targeted, minimal changes to maintain API stability and reduce regression risk while supporting evolving platform requirements.
