pseq: Update documentation for multi-chassis Update the phosphor-power-sequencer documentation to define the support required for multiple chassis systems. The support described is currently only in the design stage. After this review is complete, future commits will implement the multiple chassis support. The goal is for the phosphor-power-sequencer support to be largely unchanged for single chassis systems. This documentation also refers to planned enhancements to two other applications: * phosphor-chassis-state-manager (enhance multi-chassis support) * phosphor-chassis-power (new application) Change-Id: I10ed0ba3c73008ba297c8c7b47293eefc998a2ea Signed-off-by: Shawn McCarney <shawnmm@us.ibm.com>
This repository contains applications for configuring and monitoring devices that deliver power to the system.
Actively-maintained applications:
Legacy applications:
To build all applications in this repository:
meson setup build ninja -C build
To clean the repository and remove all build output:
rm -rf build
You can specify meson options to customize the build process. For example, you can specify:
Several applications in this repository require a PSU JSON config to run. The JSON config file provides information for:
There is an example psu.json to describe the necessary configurations.
inventoryPMBusAccessType
defines the pmbus access type, which tells the service which sysfs type to use to read the attributes. The possible values are:
/sys/bus/i2c/devices/3-0069/
/sys/bus/i2c/devices/3-0069/hwmon/hwmonX/
/sys/kernel/debug/pmbus/hwmonX/
/sys/kernel/debug/<driver>.<instance>/
/sys/kernel/debug/pmbus/hwmonX/cffps1/
fruConfigs
defines the mapping between the attribute file and the FRU inventory interface and property. The configuration example below indicates that the service will read part_number
attribute file from a directory specified by the above pmbus access type, and assign to PartNumber
property in xyz.openbmc_project.Inventory.Decorator.Asset
interface.
"fruConfigs": [ { "propertyName": "PartNumber", "fileName": "part_number", "interface": "xyz.openbmc_project.Inventory.Decorator.Asset" } ]
psuDevices
defines the kernel device dir for each PSU in inventory. The configuration example below indicates that powersupply0
's device is located in /sys/bus/i2c/devices/3-0069
.
"psuDevices": { "/xyz/openbmc_project/inventory/system/chassis/motherboard/powersupply0" : "/sys/bus/i2c/devices/3-0069", }
