soft-off: ensure only one soft off service runs

OpenBMC has two implementations of the soft off function. This function
is utilized to tell the host to shutdown gracefully and for the BMC to
wait for that shutdown.

The implementation used depends on the interface being used to talk
with the host. There is the IPMI based interface and the new PLDM based
interface.

In theory, only one of these interfaces should be used to talk with the
host on a system. In reality there are some systems such as rainier
which are in the process of switching from IPMI to PLDM. In this case
both services for soft off are installed into the image.

Since this co-existence of both packages on a single system is a
temporary situation, put a simple change in which ensures the IPMI soft
off service does not run if the PLDM one is present. The assumption here
is that if the newer PLDM based package is installed, the system owner
prefers the PLDM soft off service be utilized.

OpenBMC

Build Status

The OpenBMC project can be described as a Linux distribution for embedded devices that have a BMC; typically, but not limited to, things like servers, top of rack switches or RAID appliances. The OpenBMC stack uses technologies such as Yocto, OpenEmbedded, systemd, and D-Bus to allow easy customization for your server platform.

Setting up your OpenBMC project

1) Prerequisite

  • Ubuntu 14.04
sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat
  • Fedora 28
sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake \
    rpcgen perl-Thread-Queue perl-bignum perl-Crypt-OpenSSL-Bignum
sudo dnf groupinstall "C Development Tools and Libraries"

2) Download the source

git clone git@github.com:openbmc/openbmc.git
cd openbmc

3) Target your hardware

Any build requires an environment set up according to your hardware target. There is a special script in the root of this repository that can be used to configure the environment as needed. The script is called setup and takes the name of your hardware target as an argument.

The script needs to be sourced while in the top directory of the OpenBMC repository clone, and, if run without arguments, will display the list of supported hardware targets, see the following example:

$ . setup <machine> [build_dir]
Target machine must be specified. Use one of:

centriq2400-rep         nicole                     stardragon4800-rep2
f0b                     olympus                    swift
fp5280g2                olympus-nuvoton            tiogapass
gsj                     on5263m5                   vesnin
hr630                   palmetto                   witherspoon
hr855xg2                qemuarm                    witherspoon-128
lanyang                 quanta-q71l                witherspoon-tacoma
mihawk                  rainier                    yosemitev2
msn                     romulus                    zaius
neptune                 s2600wf

Once you know the target (e.g. romulus), source the setup script as follows:

. setup romulus build

For evb-ast2500, please use the below command to specify the machine config, because the machine in meta-aspeed layer is in a BSP layer and does not build the openbmc image.

TEMPLATECONF=meta-evb/meta-evb-aspeed/meta-evb-ast2500/conf . openbmc-env

4) Build

bitbake obmc-phosphor-image

Additional details can be found in the docs repository.

OpenBMC Development

The OpenBMC community maintains a set of tutorials new users can go through to get up to speed on OpenBMC development out here

Build Validation and Testing

Commits submitted by members of the OpenBMC GitHub community are compiled and tested via our Jenkins server. Commits are run through two levels of testing. At the repository level the makefile make check directive is run. At the system level, the commit is built into a firmware image and run with an arm-softmmu QEMU model against a barrage of CI tests.

Commits submitted by non-members do not automatically proceed through CI testing. After visual inspection of the commit, a CI run can be manually performed by the reviewer.

Automated testing against the QEMU model along with supported systems are performed. The OpenBMC project uses the Robot Framework for all automation. Our complete test repository can be found here.

Submitting Patches

Support of additional hardware and software packages is always welcome. Please follow the contributing guidelines when making a submission. It is expected that contributions contain test cases.

Bug Reporting

Issues are managed on GitHub. It is recommended you search through the issues before opening a new one.

Questions

First, please do a search on the internet. There's a good chance your question has already been asked.

For general questions, please use the openbmc tag on Stack Overflow. Please review the discussion on Stack Overflow licensing before posting any code.

For technical discussions, please see contact info below for IRC and mailing list information. Please don't file an issue to ask a question. You'll get faster results by using the mailing list or IRC.
