psu-ng: Add DEGLITCH_LIMIT, deglitch pgoodFault While the power supply should not arbitrarily report a PGOOD fault, and then turn it back off, there is a perception that this is indeed possible, a glitch of some sort. To avoid possibly logging an error for an erroneous fault reporting, make sure the fault is reported more than once before considering it to be a true fault (deglitch the signal). Tested: Real Rainier 2S2U: Verify tracing PGOOD faults seen and cleared, no error logged Verify PGOOD/OFF error logged when manually set ON_OFF_CONFIG & OPERATION. Verify deglitched PGOOD again on restart service (ON_OFF_CONFIG reset). Change-Id: I54f775004d2e363cff21ff0512bd9283408f1f72 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", }
