tools/bpf: bpftool: add btf percpu map formated dump
The btf pretty print is added to percpu arraymap,
percpu hashmap and percpu lru hashmap.
For each <key, value> pair, the following will be
added to plain/json output:
{
"key": <pretty_print_key>,
"values": [{
"cpu": 0,
"value": <pretty_print_value_on_cpu0>
},{
"cpu": 1,
"value": <pretty_print_value_on_cpu1>
},{
....
},{
"cpu": n,
"value": <pretty_print_value_on_cpun>
}
]
}
For example, the following could be part of plain or json formatted
output:
{
"key": 0,
"values": [{
"cpu": 0,
"value": {
"ui32": 0,
"ui16": 0,
}
},{
"cpu": 1,
"value": {
"ui32": 1,
"ui16": 0,
}
},{
"cpu": 2,
"value": {
"ui32": 2,
"ui16": 0,
}
},{
"cpu": 3,
"value": {
"ui32": 3,
"ui16": 0,
}
}
]
}
