Subject[PATCH 30/44] perf annotate: Introduce the --stdio2 output mode
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

This uses the TUI augmented formatting routines, modulo interactivity.

# perf annotate --ignore-vmlinux --stdio2 _raw_spin_lock_irqsave
_raw_spin_lock_irqsave() /proc/kcore
Event: cycles:ppp

Percent

Disassembly of section load0:

ffffffff9a8734b0 <load0>:
nop
push %rbx
50.00 pushfq
pop %rax
nop
mov %rax,%rbx
cli
nop
xor %eax,%eax
mov $0x1,%edx
50.00 lock cmpxchg %edx,(%rdi)
test %eax,%eax
↓ jne 2b
mov %rbx,%rax
pop %rbx
← retq
2b: mov %eax,%esi
→ callq queued_spin_lock_slowpath
mov %rbx,%rax
pop %rbx
← retq
