April 2026 (NVIDIA/libpldm) delivered targeted fixes and stability improvements for 64-bit PLDM numeric effecter support, driving reliability and spec-compliance across the BMC PLDM stack. Key focus areas: - Stabilized decoding of numeric effecter PDR data with full 64-bit support and correct endianness handling. - Aligned effecter data size and range format enums to DSP0248 v1.3.0 to enable UINT64/SINT64 handling. - Fixed upstream enum validation bug to stop rejecting 64-bit data (correct max enum usage and validation path). - Integrated stabilization into develop branch with the merge, ensuring long-term maintainability. - Validated fixes on hardware/test setup (VR-NVL-HMC SatMC) showing correct 64-bit decoding and Max/Min values. Overall impact: - Improved data integrity for 64-bit effecters, reduced risk of data truncation, and enhanced platform interoperability with 64-bit PLDM sensors/effecters. - Strengthened end-to-end reliability for monitoring and control pipelines, enabling scalable sensor data support and easier future extension. Technologies/skills demonstrated: - C/C++ implementations with careful endianness handling, enum alignment, and data validation. - Protocol conformance (DSP0248 v1.3.0) and upstream bug-fix workflows. - Merge/pipeline discipline and targeted hardware validation.

For 2025-11, NVIDIA/libpldm delivered a focused feature upgrade that expands PLDM data type support to include 64-bit sensor and effecter values. This work aligns with the DSP0248 v1.3.0 specification and lays the groundwork for handling larger telemetry and control data across platforms.
