On OpenBMC, IPMI is currently the primary industry-standard means of
communication between the BMC and the Host firmware. Due to some inherent
limitations of IPMI on OpenPOWER servers, there is a need to improve upon
the communication protocol.
This design aims to employ Platform Level Data Model (PLDM), a standard
application layer communication protocol defined by the DMTF. PLDM draws
inputs from IPMI, but it overcomes most of the latter's limitations. PLDM
is also designed to run on standard transport protocols, for e.g. MCTP
(also designed by the DMTF). MCTP provides for a common transport layer
over several physical channels, by defining hardware bindings. The
solution of PLDM over MCTP also helps overcome some of the limitations of
the hardware channels that IPMI uses.
PLDM is designed to be an effective interface and data model that provides
efficient access to low-level platform inventory, monitoring, control,
event, and data/parameters transfer functions.

The serie of patches put in place external libraries to handle the MCTP
and PLDM protocols. New series will be provided later for the management
of requests to and from the host.
- MCTP over LPC Binding.
- PLDM responder.
- PLDM requester.
- PLDM Platform requests.
- PLDM Bios requests.
- PLDM File IO requests.
- PLDM LID Files handling.
- MCTP over PCIe VDM Binding.
To enable the new PLDM feature add CONFIG_PLDM as a parameter:
make .... CONFIG_PLDM=1
