Perf tool is at the core of driverless Intel VTune Profiler analysis flow and gears efficient performance observability and analysis on Linux!

#VTune

[Arnaldo Carvalho de Melo @acmel]

Also, if you use VTune, are you aware that it:

"enables driverless sampling data collection based on the Linux Perf tool functionality"

https://t.co/7qc07m5pj5

and that this is driving tools/perf improvements in the kernel codebase?

New capabilities in 5.8: https://t.co/KktllIwoFA

"The end result of this work is that it will be possible to do quite a bit of network administration, performance monitoring, and tracing work without full root (or even full CAP_SYS_ADMIN) access."

The series is already at my perf/core branch at:

Hey!

Go find more about how Intel VTune profiler is powered by
Linux Perf without special kernel drivers:

@trav_downs @acmel By "the others" I mean group of access control bits on the right in the mask for perf binary . It should be like this -rwxr-x(---).

[Alexei Budankov @ABudankov]

@acmel @trav_downs Like this:
-rwxr-x---. 1 root perf_users 16968552 Apr 9 13:10 /home/perf/bin/perf

[Alexei Budankov @ABudankov]

@acmel @trav_downs Also make it available to perf_users group only: - rwxr-x---. The others are controlled by perf_paranoid setting...
