meta-ibm:pstore: remove console from ramoops

The documentation for CONFIG_PSTORE_CONSOLE indicates the following:
"pstore will log all kernel messages, even if no oops or panic happened"

This causes a console-ramoops-0 to appear in /var/lib/systemd/pstore/ on
any BMC reboot. This in turn causes phosphor-debug-collector, which
monitors for any files in this directory, to generate a BMC dump with
the file. This is not what we want.

What we really need are the dmesg-ramoops-* files which are generated
when a kernel panic or oops occur. Remove the CONSOLE setting so we only
get dumps when an actual BMC failure occurs.

Tested:
- Verified that console-ramoops-0 file no longer appears in
  /var/lib/systemd/pstore/ after a BMC reboot.
- Verified we still get needed dmesg-ramoops-* files when a kernel panic
  occurs.

OpenBMC

Build Status

OpenBMC is a Linux distribution for management controllers used in devices such as servers, top of rack switches or RAID appliances. It uses Yocto, OpenEmbedded, systemd, and D-Bus to allow easy customization for your 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         f0b                     fp5280g2
gsj                     hr630                   hr855xg2
lanyang                 mihawk                  msn
neptune                 nicole                  olympus
olympus-nuvoton         on5263m5                p10bmc
palmetto                qemuarm                 quanta-q71l
romulus                 s2600wf                 stardragon4800-rep2
swift                   tiogapass               vesnin
witherspoon             witherspoon-tacoma      yosemitev2
zaius

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

. setup romulus

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 Discord 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 Discord.
