Python script that prints the top N most executed functions in QEMU
using perf.
Example Usage:
topN_perf.py -n 20 -- /path/to/qemu program -program -flags
If '-n' is not specified, the default is 25.
Example Output:
No. Percentage Name Caller

The command line above is hardly example of usage. Furthermore, it is
unclear of what you meant with "program -program". Other things are unclear
too (what about qemu options?) The command line, as is now, is somewhere
between a syntax description and an example of usage, but is neither a
syntax description nor example of usage.
From the script, it looks that there is "-h" too. Not mentioned in commit
message ar all, and it shouldbe.
I would suggest that you rework this section inthis way, for the sake of
clarity:
Syntax: (
topN_perf.py [-h] [-n <number of displayed top functions > -- <qemu
executable> [<qemu executable options>] <target executable> [<target
execurable options>]
-h - .........explain here
-n - .........explain here
Example of usage:
topN_perf.py -n 20 -- qemu-arm coulomb_double-arm
Example of output:
..... and here you continue with:

I would avoid mixing stderr message and your message practically in one
sentence. Better:
error: <text from stderr>
You must run the script with sudo pivilages, or, alternatively, set kernel
Xxx option to....

I am really confused by using both perf.data and tmp.perf.data names. Why?
They are in entirely different format. "tmp.perf.data should be
perf.top-function.list, let's say, if I am not mistaken about its meaning
and usage.

Python script that prints the top N most executed functions in QEMU
using callgrind.
Example Usage:
topN_callgrind.py -n 20 -- /path/to/qemu program -program -flags
If '-n' is not specified, the default is 25.
Example Output:

The cover letters for v2, v3,... should repeat the core text of the
original cover letter. You can keep this link above, but you must repeat
the almost all text of v1 cover letter in v2, v3,... too. Any version of
any series should be a stand-alone unit, and the reader should not be
forced to look at the previous versions to find out what the series is
really about, which is the case now for this v2 of your series.
Thanks,
Aleksandar
