[lttng-dev] lttng on aarch64 platform

[Ronan CHAUVIN]

Hello all,

I am trying to use lttng 2.7.0 on an aarch64 platform. When I create my 
session a trap is triggered which indicated that a unknow syscall (389) 
is called.

/ # lttng -vvv create mysession
DEBUG1 - 02:36:22.271714 [850/850]: Session daemon binary path: 
/usr/bin/lttng-sessiond (in launch_sessiond() at commands/create.c:668)
Spawning a session daemon
DEBUG1 - 02:36:24.275751 [850/850]: Session daemon terminated normally 
(exit status: 1) (in spawn_sessiond() at commands/create.c:606)
Error: Session daemon terminated with an error (exit status: 1)
Error: Problem occurred while launching session daemon 
(/usr/bin/lttng-sessiond)
Error: Command error
DEBUG1 - 02:36:24.275899 [850/850]: Clean exit (in clean_exit() at 
lttng.c:193)

It seems that lttng-sessiond deamon is directly exited. Has anyone 
already tried on a 3.10 kernel and aarch64 platform?

Thanks in advance,
