Linux kernel source tree
It'd be better to have them in hex to check cacheline alignment.
Percent offset size field
100.00 0 0x1c0 struct cfs_rq {
0.00 0 0x10 struct load_weight load {
0.00 0 0x8 long unsigned int weight;
0.00 0x8 0x4 u32 inv_weight;
};
0.00 0x10 0x4 unsigned int nr_running;
14.56 0x14 0x4 unsigned int h_nr_running;
0.00 0x18 0x4 unsigned int idle_nr_running;
0.00 0x1c 0x4 unsigned int idle_h_nr_running;
...
Committer notes:
Justification from Namhyung when asked about why it would be "better":
Cache line sizes are power of 2 so it'd be natural to use hex and
check whether an offset is in the same boundary. Also 'perf annotate'
shows instruction offsets in hex.

> Maybe this should be selectable?
I can add an option and/or a config if you want.

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 reStructuredText markup notation.
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.
