psu-ng: Lower input history sync delay to 5ms The delay for the sync GPIO was set to 1100ms due to a PSU firmware bug. This can be lowered back down to 5ms with the updated PSU firmware for the 1600W power supplies. Change-Id: I1be327864ce9f37b3604d5e96b25cabe3d170551 Signed-off-by: Brandon Wyman <bjwyman@gmail.com>
This repository contains applications for configuring and monitoring devices that deliver power to the system.
To build all applications in this repository:
meson 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/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", }
