meta-ibm:ncsi: ensure eth speeds set to 1 gigabit IBM has run into some issues recently with certain network configurations where eth1 is not getting set to 1 gigabit. This can cause issues in scenarios where a network environment is running on 1 gigabit minimum-speed network switches. Removing link-local support from eth1 seemed to aggravated this. link-local is only on eth0 to avoid subnet issues. But without link-local, the systemd call, systemd-networkd-wait-online, does not always find an active eth1 so it never runs the command to force eth1 up to 1 gigabit. As far as we can tell, there's no appropriate mapping within systemd-networkd-wait-online for it to know when the NCSI stack is appropriately up on a network interface (allowing the 1 gigabit speed to be set). Therefore the solution taken in this commit is to just keep retrying for a period of time. Tested: - Verified new script ran and set eth ports as expected Signed-off-by: Andrew Geissler <firstname.lastname@example.org> Change-Id: I6737e208b59830262f51a8e30c78a97fc698e4fd
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: bletchley mori s8036 dl360poc mtjade swift e3c246d4i mtmitchell tatlin-archive-x86 ethanolx nicole tiogapass evb-ast2500 olympus-nuvoton transformers evb-ast2600 on5263m5 vegman-n110 evb-npcm750 p10bmc vegman-rx20 f0b palmetto vegman-sx20 fp5280g2 qcom-dc-scm-v1 witherspoon g220a quanta-q71l witherspoon-tacoma gbs romed8hm3 x11spi greatlakes romulus yosemitev2 gsj s2600wf zaius kudo s6q lannister s7106
Once you know the target (e.g. romulus), source the
setup script as follows:
. setup romulus

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.
