There is a requirement to let perf annotate support displaying the IPC/Cycle. In previous patch, this is supported in TUI mode. While it's not convenient for users since they have to take screen shots and copy/paste data.
This patch series introduces a new option '--tui-dump' in perf annotate to dump the TUI output to stdio.
User can easily use the command line like: 'perf annotate --tui-dump > /tmp/log.txt' For example: $ perf annotate compute_flag --tui-dump
Percent IPC Cycle
Disassembly of section .text:
0000000000400640 <compute_flag>: compute_flag(): volatile int count; static unsigned int s_randseed;
__attribute__((noinline)) int compute_flag() { 23.00 1.16 sub $0x8,%rsp int i;
i = rand() % 2; 23.06 1.16 1 callq rand@plt
return i; 27.01 3.38 mov %eax,%edx } 3.38 add $0x8,%rsp { int i;
i = rand() % 2;
return i; 3.38 shr $0x1f,%edx 3.38 add %edx,%eax 3.38 and $0x1,%eax 3.38 sub %edx,%eax } 26.93 3.38 2 retq
The '--stdio' option is still kept now. Maybe in future, we can only maintain the TUI routines and drop the lagacy stdio code. But right now we'd better keep it until the '--tui-dump' option is good enough.
