Hi, is there an alternative to Kernel/Systemtap - Ubuntu Wiki ?
As I cant install via:
sudo apt-get install linux-image-$(uname -r)-dbgsym

#apt-get install linux-image-$(uname -r)-dbgsym
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package linux-image-4.9.140-tegra-dbgsym
E: Couldn’t find any package by glob ‘linux-image-4.9.140-tegra-dbgsym’
E: Couldn’t find any package by regex ‘linux-image-4.9.140-tegra-dbgsym’

any help will be greatly appreciated.

Thanks!

What you want to debug/compile using systemtap? Based on that, can tell alternative.
Is systemtap supported for arm64?

Hi, I would like to trace the hrtimer to check the queue time. Thanks!

you can use hrtimer events from ftrace
root@jetson:/sys/kernel/debug/tracing/events# cat timer/
enable hrtimer_init/ timer_cancel/
filter hrtimer_start/ timer_expire_entry/
hrtimer_cancel/ itimer_expire/ timer_expire_exit/
hrtimer_expire_entry/ itimer_state/ timer_init/
hrtimer_expire_exit/ tick_stop/ timer_start/
