This is to pave the way for other BTF types, i.e. we try to find BTF type then use things like btf_is_enum(btf_type) that we cached to find the right strtoul and scnprintf routines. For now only enum is supported, all the other types simple return zero for scnprintf which makes it have the same behaviour as when BTF isn't available, i.e. fallback to no pretty printing. Ditto for strtoul. root@x1:~# perf test -v enum 124: perf trace enum augmentation tests : Ok root@x1:~# perf test -v enum 124: perf trace enum augmentation tests : Ok root@x1:~# perf test -v enum 124: perf trace enum augmentation tests : Ok root@x1:~# perf test -v enum 124: perf trace enum augmentation tests : Ok root@x1:~# perf test -v enum 124: perf trace enum augmentation tests : Ok root@x1:~# Signed-off-by: Howard Chu <howardchu95@gmail.com> Tested-by: Howard Chu <howardchu95@gmail.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Howard Chu <howardchu95@gmail.com> Cc: Ian Rogers <irogers@google.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lore.kernel.org/r/20240624181345.124764-9-howardchu95@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
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.
