Question
Body
i have macos locally and i want to do some
perf
analysis. i was able to install linux-tools-generic and useperf
but I get the following:if i run it with
sudo
i get:which isn't very helpful, since what I actually plan to analyze is instruction count.
i tried editing
/proc/sys/kernel/perf_event_paranoid
and/etc/sysctl.conf
but it seems like i'm not allowed to edit these.does anyone know how I could use codespaces to benchmark and record perf data?
thanks!
