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.
Instrument the build files for the two libraries to allow function tracing
by the gcc/clang flags -finstrument-functions and run workload as follows
- Instrument the build files for the two libraries to allow function
tracing by the gcc/clang flags *-finstrument-functions* and run workload
as follows
- LD_PRELOAD=liblttng-ust-cyg-profile.so ./rocminfo
- Instrument the application as well for the gcc/clang flag along with
the two libs
- LD_PRELOAD=liblttng-ust-cyg-profile.so ./rocminfo
I am using LTTng version Ubuntu: LTTng Stable 2.12 PPA
- apt-get install lttng-tools
- apt-get install lttng-modules-dkms
- apt-get install liblttng-ust-dev
I noticed no kernel modules with substring "ltt" in it.
Any help is appreciated.
Regards,
Ramesh
