Hello,
Some old topic, see
https://lists.lttng.org/pipermail/lttng-dev/2019-November/029411.html.
(I actually thought this was solved meanwhile).
With lttng 2.13 liburcu is replicated in lttng-ust so my old custom
hack aint helping.
Aside from another crude hack, I thought about doing this:
extern int lttng_ust_urcu_has_sys_membarrier;
int setup() {
lttng_ust_urcu_has_sys_membarrier = 0;
}
this is obvious possible in my own program, but I don't know if some
lttng daemon would need to update RCU structures in shared memory that
should sync to other processes (and wont do that with sys_membarrier
in case of Xenomai threads)?
Seems safer to me to hack it out once more...
Norbert
