disable warm reboot on romulus Similar to commit 567a8d for witherspoon, this issue has now popped up on Romulus hardware. 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 Romulus, do 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 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.

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

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.
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 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.
