libtraceevent has added more levels of debug printout and with changes like: https://lore.kernel.org/linux-trace-devel/20210507095022.1079364-3-tz.stoyanov@gmail.com previously generated output like "registering plugin" is no longer displayed. This change makes it so that if perf's verbose debug output is enabled then the debug and info libtraceevent messages can be displayed. This change was previously posted: https://lore.kernel.org/linux-perf-users/20210923001024.550263-4-irogers@google.com/ and reverted: https://lore.kernel.org/linux-perf-users/20220109153446.160593-1-acme@kernel.org/ The previous failure was due to -Itools/lib being on the include path and libtraceevent in tools/lib being version 1.1.0. This meant that when LIBTRACEEVENT_VERSION was 1.3.0 the #if succeeded, but the header file for libtraceevent (taken from tools/lib rather than the intended /usr/include) was for version 1.1.0 and function definitions were missing. Since the previous issue the -Itools/lib include path has been removed: https://lore.kernel.org/lkml/20221109184914.1357295-1-irogers@google.com/ As well as libtraceevent 1.1.0 has been removed from tools/lib: https://lore.kernel.org/lkml/20221130062935.2219247-1-irogers@google.com/ Signed-off-by: Ian Rogers <irogers@google.com> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Cc: Eelco Chaudron <echaudro@redhat.com> Cc: German Gomez <german.gomez@arm.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Kim Phillips <kim.phillips@amd.com> Cc: Leo Yan <leo.yan@linaro.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Sean Christopherson <seanjc@google.com> Cc: Stephane Eranian <eranian@google.com> Cc: Yang Jihong <yangjihong1@huawei.com> Link: https://lore.kernel.org/r/20230111070641.1728726-3-irogers@google.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

README
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.
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.
