When perf record ... is setup to record data, the s390 cpu information was a fixed string "IBM/S390". Replace this string with one containing more information about the machine. The information included in the cpuid is a comma separated list: manufacturer,type,model-capacity,model[,version,authorization] with - manufacturer: up to 16 byte name of the manufacturer (IBM). - type: a four digit number refering to the machine generation. - model-capacitiy: up to 16 characters describing number of cpus etc. - model: up to 16 characters describing model. - version: the CPU-MF counter facility version number, available on LPARs only, omitted on z/VM guests. - authorization: the CPU-MF counter facility authorization level, available on LPARs only, omitted on z/VM guests.
