transport: Improve startup error message

When pldmd is unable to setup the transport layer the following message
is displayed:

terminate called after throwing an instance of 'std::system_error'
  what():  Cannot allocate memory

This is problematic because:

1 - There is no mention of the context of the error (transport layer
setup).
2 - There are many reasons the transport layer setup may fail beyond and
more likely than memory allocation failures.

Remove the memory allocation failure assumption and provide the context.

Tested: Forced transport setup failure and observed the new error

PLDM - Platform Level Data Model

License

Overview

PLDM (Platform Level Data Model) is a key component of the OpenBMC project, providing a standardized data model and message formats for various platform management functionalities. It defines a method to manage, monitor, and control the firmware and hardware of a system.

The OpenBMC PLDM project aims to implement the specifications defined by the Distributed Management Task Force (DMTF), allowing for interoperable management interfaces across different hardware and firmware components.

Features

  • Standardized Messaging: Adheres to the DMTF's PLDM specifications, enabling consistent and interoperable communication between different components.
  • Modularity: Supports multiple PLDM types, including base, FRU,Firmware update, Platform Monitoring and Control, and BIOS Control and Configuration.
  • Extensibility: Easily extendable to support new PLDM types and custom OEM commands.
  • Integration: Seamlessly integrates with other OpenBMC components for comprehensive system management.

Getting Started

Prerequisites

To build and run PLDM, you need the following dependencies:

  • Meson
  • Ninja

Alternatively, source an OpenBMC ARM/x86 SDK.

Building

To build the PLDM project, follow these steps:

meson setup build && meson compile -C build

To run unit tests

The simplest way of running the tests is as described by the meson man page:

meson test -C build

Alternatively, tests can be run in the OpenBMC CI docker container using these steps.

To enable pldm verbosity

pldm daemon accepts a command line argument --verbose or --v or -v to enable the daemon to run in verbose mode. It can be done via adding this option to the environment file that pldm service consumes.

echo 'PLDMD_ARGS="--verbose"' > /etc/default/pldmd
systemctl restart pldmd

To disable pldm verbosity

rm /etc/default/pldmd
systemctl restart pldmd
