Subject: [PATCH 5.19 070/101] perf parse-events: Break out tracepoint and printing
Date: Mon, 3 Oct 2022 09:11:06 +0200 [thread overview]
Message-ID: <20221003070726.211212627@linuxfoundation.org> (raw)
In-Reply-To: <20221003070724.490989164@linuxfoundation.org>
From: Ian Rogers <irogers@google.com>
[ Upstream commit 9b7c7728f4e4ba8dd75269fb111fa187faa018c6 ]
Move print_*_events functions out of parse-events.c into a new
print-events.c. Move tracepoint code into tracepoint.c or
trace-event-info.c (sole user). This reduces the dependencies of
parse-events.c and makes it more amenable to being a library in the
future.
Remove some unnecessary definitions from parse-events.h. Fix a
checkpatch.pl warning on using unsigned rather than unsigned int. Fix
some line length warnings too.
