The 'perf record -s' and 'perf report -T' should be used together to see
per-thread event counts. Document the relation of these commands.

The -T/--thread option is supported only on --stdio mode (at least for
now). So enforce the tty output if the option was requested.

It seems there's no reason to suppress per-thread event stat by -T
option when -s or -p option is used. Make it work with those options.

perf-report can verify that inherit_stat is set in attr's if
show_threads is requested.

I will apply, but please consider sending a followup patch to emit a
warning for the cases when --tui or --gtk is explicitely passed, i.e.
emit a warning saying that that is not possible.

It seems that it's because the commit e944ec2ca00f ("perf report: Fix
-T/--threads option to work again") in the perf/urgent is not merged
to the perf/core yet.
I'll resend v2 soon.

Currently --header, --header-only and --threads/-T options are supported
on stdio mode only. Show warning if user passes one of --tui or --gtk
option with these like below:
$ perf report -T --tui
Error: --threads option cannot be used with --tui
usage: perf report [<options>]
-T, --threads Show per-thread event counters
--tui Use the TUI interface

Check the evsel->attr.inherit_stat bit and show warning message if it's
missing and -T/--threads option was given:
$ perf report -T
Error: perf.data file has no per-thread stat data.

So thanks for that! Can you please check that it applies on top of my
perf/core branch? I had already applied your patch :-\ Just pushed the
branch, should be at git.kernel.org soon.

Check the evsel->attr.inherit_stat bit and show warning message if it's
missing and -T/--threads option was given:
$ perf report -T
Error: perf.data file has no per-thread stat data.
Did you run 'perf record' with -s option?

perf tools: Document relation of per-thread event count feature
The 'perf record -s' and 'perf report -T' should be used together to see
per-thread event counts. Document the relation of these commands.

perf report: Force tty output if -T/--thread option is given
The -T/--thread option is supported only on --stdio mode (at least for
now). So enforce the tty output if the option was requested.

perf report: Do not restrict -T option by other options
It seems there's no reason to suppress per-thread event stat by -T
option when -s or -p option is used. Make it work with those options.
