Functionality wise a really good improvement - thanks! But personally I find
the abbreviation of one character (i.e. "Percnt" instead of "Percent") not so
nice. If space really is an issue here, use "%"?
Also note though that it's unclear what this percentage actually is. I guess
it's a sample percentage? Maybe a header should be added that explains these
values to newbies. I bet many people won't even know what IPC is either.
Cheers

Ok, will make it 'Percent' as we have space for that, and will add
Acked-by: Millian, ok?

Perhaps we could have some help files, then when the user presses 'h'
one of the lines would be:
h Report explanation (columns, etc)
?

Yeah I think that would be a good addition for the future.

Sure, sorry about that, c'n'pasted from a message from you, so should be
all well.

The patch series adds the titles "Percnt", "IPC" and "Cycle" in
annotate browser. It helps user to understand easily for what the
columns in left frame represents for.
For example:
Percnt IPC Cycle │
│25 __attribute__((noinline))
│26 int compute_flag()
│27 {
22.80 1.20 │ sub $0x8,%rsp
│25 int i;
│
│27 i = rand() % 2;
22.78 1.20 1 │ → callq rand@plt
The patch "perf report: Remove the unnecessary checking in
annotate_browser_write" removes the invalid condition checking in
current code.

In annotate_browser_write(),
if (dl->offset != -1 && percent_max != 0.0) {
if (percent_max != 0.0) {
...
}
...
}
The second checking of (percent_max != 0.0) is not necessary,
so remove it.

The annotate browser is divided into 2 frames. Left frame
contains 3 columns (some platforms only have one column).
For example:
│26 int compute_flag()
│27 {
22.80 1.20 │ sub $0x8,%rsp
│25 int i;
│
│27 i = rand() % 2;
22.78 1.20 1 │ → callq rand@plt
While it's hard for user to understand what the data is.
This patch adds the titles "Percent", "IPC" and "Cycle"
on columns.
Percnt IPC Cycle │
│25 __attribute__((noinline))
│26 int compute_flag()
│27 {
22.80 1.20 │ sub $0x8,%rsp
│25 int i;
│
│27 i = rand() % 2;
22.78 1.20 1 │ → callq rand@plt
The titles are displayed at row 0 of annotate browser if row 0
doesn't have values of percent, ipc and cycle.

perf annotate browser: Display titles in left frame
The annotate browser is divided into 2 frames. Left frame contains 3
columns (some platforms only have one column).
For example:
│26 int compute_flag()
│27 {
22.80 1.20 │ sub $0x8,%rsp
│25 int i;
│
│27 i = rand() % 2;
22.78 1.20 1 │ → callq rand@plt
While it's hard for user to understand what the data is.
This patch adds the titles "Percent", "IPC" and "Cycle" on columns.
Percent IPC Cycle │
│25 __attribute__((noinline))
│26 int compute_flag()
│27 {
22.80 1.20 │ sub $0x8,%rsp
│25 int i;
│
│27 i = rand() % 2;
22.78 1.20 1 │ → callq rand@plt
The titles are displayed at row 0 of annotate browser if row 0 doesn't
have values of percent, ipc and cycle.
