Subject[PATCH v1 0/4] perf annotate: Create a new '--tui-dump' option
Date
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.

Jin Yao (4):
perf browser: Add a new 'dump' flag
perf browser: bypass ui_init if in tui dump mode
perf annotate: Process the new switch flag tui_dump
perf annotate: Enable the '--tui-dump' mode
