System Processor
System processor information is sourced from the UEFI and stored in the BMC's persistent memory. This data may be lost after a BMC factory reset and will be restored upon the next UEFI reboot.
A high-level summary of the BlueField processors is available in the ProcessorSummary object within the Redfish ComputerSystem schema.
To retrieve this information, run the following command:
curl -k -u <bmc_username>:<bmc_password> -H 'Content-Type: application/json' -X GET https://<bmc_ip>/redfish/v1/Systems/Bluefield
Example output:
{
...,
"@odata.id": "/redfish/v1/Systems/Bluefield",
"@odata.type": "#ComputerSystem.v1_22_0.ComputerSystem",
...,
"ProcessorSummary": {
"CoreCount": 16,
"Count": 1,
"Model": "ARMv8"
},
"Processors": {
"@odata.id": "/redfish/v1/Systems/Bluefield/Processors"
},
...
}
The ProcessorSummary provides:
CoreCount– Total number of cores across all processors.Count– Total number of processors.Model– Processor model of the primary processor.
A detailed list of system processors is available in the ProcessorCollection object.
To retrieve the processor collection, run:
curl -k -u <bmc_username>:<bmc_password> -H 'Content-Type: application/json' -X GET https://<bmc_ip>/redfish/v1/Systems/Bluefield/Processors
Example output:
{
"@odata.id": "/redfish/v1/Systems/Bluefield/Processors",
"@odata.type": "#ProcessorCollection.ProcessorCollection",
"Members": [
{
"@odata.id": "/redfish/v1/Systems/Bluefield/Processors/CPU_0"
}
],
"Members@odata.count": 1,
"Name": "Processor Collection"
}
Each entry in the Members array represents a processor in the system. In this example, the collection contains a single processor: CPU_0.
Detailed information about an individual processor is provided in the Redfish Processor schema.
To retrieve information for CPU_0, run the following command:
curl -k -u <bmc_username>:<bmc_password> -H 'Content-Type: application/json' -X GET https://<bmc_ip>/redfish/v1/Systems/Bluefield/Processors/CPU_0
