| |
A third usability bug is that for some reason a branch sampling 'perf report' defaults to the stdio output on my testsystem - with --no-branch-stack it gives the regular tui.
Even specifying --tui explicitly does not restore the TUI. Is there any fundamental reason why the branch stack does not support the TUI?
A fourth bug is that regular profiling appears to be busted:
aldebaran:> perf record -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.026 MB perf.data (~1120 samples) ]
aldebaran:~> perf report Warning: TUI interface not supported in branch mode selected -b but no branch data. Did you call perf record without -b?
Guys, why are you sending me these patches? The tooling side is utterly untested and very raw yet.
Thanks,
Ingo
