Description

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.

Keywords: Disable/enable RSHIM, HII menu

Discovered in Version: 14.33.10

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).

Keywords: NVMe ,Virtio-blk Emulation Device

Discovered in Version: 14.32.17

3639809

Description: SAN boot fails with the latest iPXE version.

Workaround: N/A

Keywords: SAN boot, iPXE

Discovered in Version: 14.32.12

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

Keywords: DELL R720, NVME UEFI

Discovered in Version: 14.24.13 (20.1.3 UEFI NVMe)

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.

Keywords: Embedded CPU, PXE, UEFI, Arm

Discovered in Version: 14.23.17

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.

Keywords: Virito-Net, UEFI, boot

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.

Workaround: N/A

Keywords: NumberVFAdvertised, HII, Mlxconfig

Discovered in Version: 14.20.19

-

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.

Discovered in Version: 14.20.19

1714094

Description: The IB link will appear as disconnected in HII menu as long as the BIOS has not initialize the UNDI protocol which is necessary to query for the IB link status.

Workaround: N/A

Keywords: HII, Link Status, IB mode

Discovered in Version: 14.18.19

1295727

Description: In Secure Host mode, the Hii protocol will be “read only”, changes will not be applied and it may cause unknown behavior.

Workaround: N/A

Keywords: Secure Host mode, Hii protocol

Discovered in Version: 14.15.19

798073

Description: UEFI driver is not supported on Supermicro X9DEW (BIOS version 3.0c).

Workaround: N/A

Keywords: BIOS, Supermicro X9DEW

-

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.

Description

3568696

Description: On BlueField-3 devices that operate on IB mode using firmware version 32.38.1002, when configuring the devices to NIC mode, the ARM side gets stuck with exception and causes the drivers (OS/PXE) on the host side to fail.

Workaround: To avoid this issue, when configuring a BlueField-3 device to NIC mode, add the following configuration:

  • If you configure NIC mode from the ARM side, please disable UEFI_HII_EN from the ARM side through the following CMD:

    mlxconfig -d <device> set UEFI_HII_EN=0

  • If you configure NIC mode from the Host side, please follow the further instructions below to avoid the issue :

    1. Create a raw file that contains the following 2 lines:

      MLNX_RAW_TLV_FILE

      0x82000204 0x03040196 0x00000000 0x00000000

    2. Use the following CMD from the host side:

      mstconfig/mlxconfig -d <device> -f <raw file> set_raw
