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.

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.

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
bitbake obmc-phosphor-image

The OpenBMC community maintains a set of tutorials new users can go through to get up to speed on OpenBMC development out here
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.
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.
Issues are managed on GitHub. It is recommended you search through the issues before opening a new one.
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.
