disable warm reboot on witherspoon

The concept of warm reboot (reboot the host without removing chassis
power) was added a while back as a part of clarifying support for
the Redfish ComputerSystem.Reset Action. It has since been found that
some IBM hardware, including Witherspoon, does not support warm reboots.
The issue is intermittent and depends on the reboot being requested
while the host is in the middle of some i2c transactions. If a warm
reboot occurs during this window, then on the subsequent boot the i2c
hardware will be in a bad state and the host firmware is unable to
recover it.

Given this issue, it has been requested that BMC software go back to
doing cold reboots (cycling power to the chassis during any reboot
request) on this hardware.

The issue has only been reported on Witherspoon so for now only disable
it on that platform.

Tested:
- Verified within QEMU that an image with this commit used the cold reboot
  target during a warm reboot request

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
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

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.
