disable warm reboot on witherspoon 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 Witherspoon, does 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 issue has only been reported on Witherspoon so for now only disable it on that platform. Tested: - Verified within QEMU that an image with this commit used the cold reboot target during a warm reboot request Signed-off-by: Andrew Geissler <geissonator@yahoo.com> Change-Id: I4045d187a6d5d6403b91903a575627d4f494ac4b
This layer provides support for the BMC firmware on IBM POWER systems server products.
This layer depends on: URI: git://git.openembedded.org/openembedded-core layers: meta branch: master revision: HEAD URI: https://github.com/openbmc/meta-phosphor branch: master revision: HEAD URI: https://github.com/openbmc/meta-openpower branch: master revision: HEAD URI: https://github.com/openbmc/meta-aspeed branch: master revision: HEAD
The following systems are supported.
Witherspoon, or AC922, is an IBM POWER9 two-socket, 2U Accelerated Compute Server with up to 6 NVIDIA Tesla GPUs. More information can be found here.
In addition to witherspoon, this layer contains additional machine configurations such as swift. The default machine target is witherspoon, so in order to build a different configuration, or to build witherspoon after building a different one, set the MACHINE environment to the desired configuration name (see the conf/machine/ subdirectory for available options):
export MACHINE=machine_configuration_name
Then build:
bitbake obmc-phosphor-image
Example:
export MACHINE=swift bitbake obmc-phosphor-image bitbake phosphor-logging export MACHINE=witherspoon bitbake obmc-phosphor-image
