meta-ibm: Redfish: Enable new power/thermal

After over a year of discussion, Redfish released new power and thermal
schemas as part of the Redfish 2020.4 release.

These new powersubsystem, thermalsubsystem, fan, powersupply, etc
schemas can co-exist with the old power and thermal schemas.

The old schemas and the new schemas are controlled by different options.

The current plan for bmcweb is:
1. Until the new schemas are all in and tested, as a default, enable the
   old schemas and disable the new.
2. After the new have been in and tested, enable them. This means the
   old and new will co-exist if running the defaults. The sensor
   collection behavior will reflect the new schemas, that is all sensors
   can be found under the sensor collection.
3. After an OpenBMC release, at a later time, disable the old and add
   appropriate deprecation.

This change here, enabling the new schemas, jumps meta-ibm to #2.
This reflects our desire for our Redfish clients to start using the new
schemas.

Some reasons why the ThermalSubsystem/PowerSubsystem are an improvement
on the existing Thermal/Power schemas:
1. They include the latest properties like LocationIndicatorActive.
2. Fans, PowerSupplies, Temperatures were arrays in the old schemas.
   This was cumbersome and could hit limits of JSON arrays.
3. Large amount of static data mixed with sensor readings, which hurt
   performance in certain cases.
4. Inconsistent definitions of properties vs newer schemas like Processor
   and Memory schemas.

Tested: Built bmcweb. See the new sensor behavior.

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.
