$ perf report perf.data
the profile is loaded, but nothing is displayed, and only the header is
shown, and at the bottom the message below is written:
perf report` shows Cannot load tips.txt file, please install perf!
The file is shipped by `linux-perf`, but it’s compressed:
$ dpkg -S /usr/share/doc/linux-perf/tips.txt.gz
linux-perf: /usr/share/doc/linux-perf/tips.txt.gz
Uncompressing the file, the message is not shown anymore. Still nothing is
shown, but that is for another bug report.
The problem with compressed tips.txt is reported at #1088747 so
merging the two bugs.
Thank you for finding this. I am sorry for causing extra work.
About not showing something, right: according to perf report -h:
-i, --input <file> input file name
Please try perf report -i perf.data. See as well perf-report(1).
(or with no arguments at all to perf report in the directory where you
have your perf.data).
Indeed, that did the trick. Thank you!
Kind regards,
Paul
