| 28.47.1026 | Transition to 2023 Microsoft UEFI Certificate Authority To align with updated Microsoft UEFI Secure Boot requirements and the upcoming end-of-life of the 2011 Certificate Authority (CA), NVIDIA is transitioning to the 2023 CA. This is the final release signed with the 2011 CA. Beginning in February 2026, all releases will be signed exclusively with the 2023 CA. To ensure successful loading of the Expansion ROM (ExpROM) during the UEFI Secure Boot process, system BIOS and operating system trust stores must be updated to include the 2023 CA. Note: Systems must be updated to recognize the 2023 CA to prevent UEFI drivers or ExpROMs from failing to load during boot before June 27, 2026. |

Introduced in Version | Description | Customer Impact and Recommendation |
28.46.1006 | Renamed firmware-generated PLDM images to include the firmware name and PSID. | |
28.43.2026 | DPA Outbox Blocking-Mode Due to a silicon issue, as of firmware version 28.43.2026, the DPA outbox is configured to operate in non-blocking mode, causing DPA outbox requests to complete immediately without waiting for actual completion. As a result, the DPA stack must poll a "busy" bit before initiating another DPA outbox operation. | Update the firmware version to 28.43.2026 or higher or update the BF-Bundle (containing this firmware) and DOCA-Host to 2.9.x or higher. This is mandatory for customers programming the DPA (e.g., DPA with DOCA PCC, or using NVIDIA turn-key apps which utilize the DPA (virtio-net/blk/fs, NVMe). |
DPA Thread Context Due to internal-stack API changes, as of firmware v28.43.2026, DPA thread context is changed in the DPA. This affects the overlying DPA stack. As of firmware version 28.43.2026, internal-stack API changes have altered the DPA thread context, impacting the overlying DPA stack. |
