Jun 2	comment	Do I need root (admin) permissions to run userspace 'perf' tool? (perf events are enabled in Linux kernel) Nice. `cat /proc/sys/kernel/perf_event_paranoid` returns 1, so it seems that I would be able to take at least some measurements (BTW. whats the difference betwen "kernel profiling data" and "CPU event data"? Reference is enough)

Jun 2	comment	Do I need root (admin) permissions to run userspace 'perf' tool? (perf events are enabled in Linux kernel) I am asking this question to decide whether it is worth trying to install (as ordinary user, in $HOME) userspace part of `perf` tool (which is/can be non-trivial).

Jun 1	accepted	Installing Gentoo packages as an ordinary user (non-root)
May 29	comment	Installing Gentoo packages as an ordinary user (non-root) Unfortunately from first browsing they do require good konwledge of Gentoo... and I am just beginning to use computer with Gentoo installed. As far as I have checked they lack step by step instruction. Still, I'll be trying.
May 28	comment	Installing Gentoo packages as an ordinary user (non-root) Could you give me step by step instruction how to install given package locally?
May 28	comment	How to check that perf events are enabled in Linux kernel, and how to install perf userland as non-root? @cjm: Thanks, rechecked just in case, and fixed. (Its 'perf' not 'prof', but it is 'gprof' not 'gperf'...).
May 28	revised	How to check that perf events are enabled in Linux kernel, and how to install perf userland as non-root? it's perf, not prof
May 28	comment	How to check that perf events are enabled in Linux kernel, and how to install perf userland as non-root? This question should IMHO use `perf_events` tag... but it does not exists yet, and I don't have enough reputation to add it.
