[Skiboot] [PATCH 09/10] pldm/libpldm: Import libpldm library handling PLDM protocol
Christophe Lombard
clombard at linux.vnet.ibm.com
Sat Feb 26 00:46:44 AEDT 2022
Platform Level Data Model (PLDM) is a standard application layer
communication protocol defined by the DMTF. PLDM is an effective data and
control source. PLDM defines a method to provide efficient access to
low-level platform inventory, monitoring, control, eventing, and
data/parameters transfer functions such as temperature, fan, voltage,
event logging, and boot control.
PLDM has defined data representations and commands that abstract the
platform management hardware.
The library deals with the encoding and decoding of PLDM messages.
The source is located here:
https://github.com/openbmc/pldm/tree/master/libpldm and use as is, without
any update.
The libpldm code is integrated into the folder ./pldm/libpldm as a set of
sources, compilated if the compiler flag CONFIG_PLDM is set.
