Arnaldo Carvalho de Melo 9974406884 perf kvm: Clarify the 'perf kvm' -i and -o command line options ... The 'perf kvm' subcommand has options that it in turn passes to other perf subcommands such as 'report' and 'record', particularly -i and -o end up setting the same variable that will then be used for 'record's -o and report '-i', which ends up being confusing, leading some to think that both -i and -o can be used with 'report'. Improve the man page to state that -i is used with the post-processing subcommands while -o is used just with 'record' and that to save the output of 'report' one should simply redirect its output to a file. Noticed while reading the https://www.linux-kvm.org/page/Perf_events page.
