Changes and New Feature in this Firmware Version

NVIDIA BlueField-2 DPU Firmware Release Notes v24.39.2048


NC-SI ChannelsAdded support for two passthrough channels on dual-port adapter cards.
Expansion ROMAdded a caching mechanism to improved expansion ROM performance and to avoid any slow boot occurrences when loading the expansion ROM driver.
Live Migration Support for Image Size above 4GBAdded support for image size above 4GB when performing a live migration by splitting the image to chunks.
Crypto AlgorithmsExtended the role-based authentication to cover all crypto algorithms. Now the TLS. IPsec. MACsec. GCM, mem2mem, and NISP work when nv_crypto_conf.crypto_policy = CRYPTO_POLICY_FIPS_LEVEL_2, meaning all cryptographic engines can also work in wrapped mode and not only in plaintext mode.
DSCP (priority) of ACK PacketsAdded the ability to configure the DSCP (priority) of ACK packets using the ROCE_ACCL access register.
Performance ImprovementsAdded support for large MTU for force loopback QPs to improve performance (using the aes_xts_tweak_inc_64 parameter). This capability is enabled by mlxconfig LARGE_MTU_TWEAK_64 parameter.
DDR Poison: DDR Uncorrectable ErrorWhen there is DDR poison (uncorrectable ECC error), firmware reports the health syndrome ICM_FETCH_PCI_DATA_POISONED_ERR (0x14), and triggers the FLR on the the function causing this error.
Due to this error, the DDR data is mostly corrupted therefore, the firmware blocks other operations on this function.
Live Firmware PatchAdded support for Live Firmware Patch.
Reserved mkeyAdded new support for reserved mkey index range. When enabled, a range of mkey indexes is reserved for mkey by name use.
Admin QueueAdded support for admin queue in virtio device object.
Enhanced NIC Mode: GGA ModulesEnabled GGA modules for all working modes (except for RXP) when using Enhanced NIC Mode.
