Hi Jonathan :)
It's very unlikely that the race could occur, BUT it can happen.
OK run
1. test_event_tracker starts gen-ust-events
2. test_event_tracker waits for gen-ust-events to create AFTER_FIRST_PATH
3. gen-ust-event create first event and create AFTER_FIRST_PATH
4. gen-ust-event continue

I might be missing something here but as far as I understand the race you are
trying
Hi Julian,
Neither mine "sleep 0.1" or your version with "while [! -f "
are race condition free.
I suggest that we add an option to gen-ust-events to wait before the first
event is generated.
gen_kernel_test_events already have this functionality to wait before the
first event.

the following tests fails on arm64
- test_event_vpid_tracker ust 0 "${EVENT_NAME}"
- test_event_vpid_track_untrack ust 0 "${EVENT_NAME}"
- test_event_pid_tracker ust 0 "${EVENT_NAME}"
- test_event_pid_track_untrack ust 0 "${EVENT_NAME}"

Thanks for the quick response, appreciate it.
At a high level this is what I did.
1. reboot
2. login as sudo
3. set LD_LIBRARY_PATH to point to right locations
4. ldd of executable to show right library versions are picked up
5. execute the workload by specifiy LD_PRELOAD env

I am trying to capture the list of functions being called by an app. The
app relies on a couple of shared libraries (libhsa-runtime64.so and
libhsakmt.so).
My experiments all *FAIL *i.e. there are no log files of the output. The
link on lttng-ust-cyg-profile does not tell me where I can get them.
