PLDM is designed to be an interface and data model that provides efficient
access to low-level platform inventory, monitoring, control, event, and
data/parameters transfer functions. For example, temperature, voltage, or
fan sensors can have a PLDM representation that can be used to monitor or
control the platform using a set of PLDM messages. PLDM over MCTP binding
defines the format of PLDM over MCTP messages.
This patch set covers these following steps:
- initialize MCTP binding over LPC Bus interface.
- define PLDM responder and PLDM control and discovery requests.
- define PLDM requester and define the functions and data structures used
for discovering, describing, initializing, and accessing sensors and
effecters within the management controllers and management devices of a
platform management subsystem using PLDM messaging.
- encode and decode APIs for in-band readFile and writeFile commands.
To enable the new PLDM features, add CONFIG_PLDM as a parameter:
make .... CONFIG_PLDM=1
This patch set should be applied on top of this previous set:
Import external libraries for MCTP/PLDM protocols.
