PMCI Support¶
All Alveo™ products, SC firmware supports the SMBus discovery via the default SMBus 2.0 at I2C slave address 0x61 (0xC2 in 8-bit) and the MCTP/PLDM protocol at I2C slave address 0x18 (0x30 in 8-bit). Alveo OoB implementation adheres to the following DMTF specifications:
- MCTP Base Specification ([DSP0236])
- MCTP SMBus Binding Spec ([DSP0237])
- PLDM Base Specification ([DSP0240])
- PLDM for Platform Monitoring and Control Specification ([DSP0248])
- PLDM for FW Update Spec ([DSP0267])
PLDM Over MCTP Over SMBus Protocol
The following figure illustrates the PLDM over MCTP over SMBus binding specification stack.
