1# PLDM - Platform Level Data Model
2
3[![License](https://img.shields.io/badge/license-Apache%202.0-blue.svg)](LICENSE)
4
5## Overview
6
7PLDM (Platform Level Data Model) is a key component of the OpenBMC project,
8providing a standardized data model and message formats for various platform
9management functionalities. It defines a method to manage, monitor, and control
10the firmware and hardware of a system.
11
12The OpenBMC PLDM project aims to implement the specifications defined by the
13Distributed Management Task Force (DMTF), allowing for interoperable management
14interfaces across different hardware and firmware components.
15
16## Features
17
18- **Standardized Messaging:** Adheres to the DMTF's PLDM specifications,
19  enabling consistent and interoperable communication between different
20  components.
21- **Modularity:** Supports multiple PLDM types, including base, FRU,Firmware
22  update, Platform Monitoring and Control, and BIOS Control and Configuration.
23- **Extensibility:** Easily extendable to support new PLDM types and custom OEM
24  commands.
25- **Integration:** Seamlessly integrates with other OpenBMC components for
26  comprehensive system management.
27
28## Getting Started
29
30### Prerequisites
31
32To build and run PLDM, you need the following dependencies:
33
34- `Meson`
35- `Ninja`
36
37Alternatively, source an OpenBMC ARM/x86 SDK.
38
39### Building
40
41To build the PLDM project, follow these steps:
42
43```bash
44meson setup build && meson compile -C build
45```
46
47### To run unit tests
48
49The simplest way of running the tests is as described by the meson man page:
50
51```bash
52meson test -C build
53```
54
55Alternatively, tests can be run in the OpenBMC CI docker container using
56[these](https://github.com/openbmc/docs/blob/master/testing/local-ci-build.md)
57steps.
58
59### To enable pldm verbosity
60
61pldm daemon accepts a command line argument `--verbose` or `--v` or `-v` to
62enable the daemon to run in verbose mode. It can be done via adding this option
63to the environment file that pldm service consumes.
64
65```bash
66echo 'PLDMD_ARGS="--verbose"' > /etc/default/pldmd
67systemctl restart pldmd
68```
69
70### To disable pldm verbosity
71
72```bash
73rm /etc/default/pldmd
74systemctl restart pldmd
75```
