3745757 |
Description: The UEFI HII "Host Priv Rshim" setting appears in the DPU UEFI HII menu, but since the setting is empty, changing it has no affect on the firmware. |
|
Workaround: In order to disable/enable RSHIM, configure the firmware only from the DPU BMC. Please ignore this setting in the DPU UEFI HII menu. |

3660603 |
Description: Driver boot fails when UEFI boot Images that include a boot loader attempt to read data larger than 2MB. |
|
Workaround: Do no use Memory Manager nor GGA for Snap3. You may use DV (configure SNAP_DMA_Q_OPMODE=2 <--- DV). |

2680852 |
Description: NVMe UEFI driver is not supported on Dell R720 BIOS version 2.9.0 as the BIOS does not support reporting valid Device Handle from EfiLoadedImagePortocol and always returns NULL. |
|
Workaround: N/A |

|
2581408 |
Description: On a BlueField device operating in Embedded CPU mode, PXE driver will fail to boot as long as the Arm side is not fully loaded and the OVS bridge is not configured. |
|
Workaround: Configure the UEFI BIOS to perform boot retires in order to wait for the Arm to come up. If the BIOS does not support retries, perform a warm reboot on the host side and reboot via the device when the Arm is up and the OVS bridge is configured. |

2353780 |
Description: In BlueField-2 x86 host side, the UEFI driver of the Virtio Net emulation device will not be loaded and the Virtio Net UEFI device will not be visible as a boot option before the Virtio-Net Controller on the Arm side is started. |
|
Workaround: Start the Virtio-Net controller on the Arm side and then run warm reboot on the host side to load the Virtio-Net UEFI driver. |

Discovered in Version: 14.20.19 |
|
|
2232461 |
Description: A mismatch in NumberVFAdvertised between the HII and the mlxconfig because in HII, the minimum value is set to 1 and in some adapter cards its value is set to 0 by the mlxconfig. Note: When setting this attribute by mlxconfig to 0, the HII will not show it, but instead it will show the default value. |

Description: PXE boot will not function if the adapter card is connected to a Mellanox Quantum™ based switch over an HDR fiber optical cable or a copper splitter because EDR and SDR speeds will not function. |
|
Workaround: Set KEEP_LINK_UP_ON_BOOT configuration to enable via mlxconfig. For further information please contact Mellanox Support. |

Description: Burning the UEFI driver will remove the Flexboot driver (Legacy BIOS driver) from the firmware. |
|
Workaround: As of firmware ConnecX-4/Lx/5 v12/14/16.22.1002, UEFI is pre-compiled for various adapter cards and can be enabled using mlxconfig. For the full list of OPNs supporting this new capability, see firmware Release Notes. |
