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,
}
}
]
}

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
