Subject: [dpdk-users] L-thread subsystem: rte_eal_remote_launch() does not work
Date: Tue, 16 Apr 2019 16:05:03 +0200	[thread overview]
Message-ID: <CACNnN_k2Gp1Z3w_P=5yZGXa=Bxi-5TTB2GdX_TZvAAZSpQ+6EQ@mail.gmail.com> (raw)

Hi all,

I am experimenting lightweigth thread (lthread) over lcore. I use lcores 0,
5 and 6.
I run this example:
https://doc.dpdk.org/api/examples_2performance-thread_2pthread_shim_2main_8c-example.html
and
the result is OK.
The result is Ok => I saw Hello from every lthread / lcore

Now, I want to replace rte_eal_mp_remote_launch(lthread_scheduler, (void
*)NULL, CALL_MASTER); by rte_eal_remote_launch(lthread_scheduler, (void
*)NULL, 5); and rte_eal_remote_launch(lthread_scheduler, (void *)NULL, 6);
But I do not see any Hello from lthread / lcore.
With gdb I enter into lthread_scheduler() but lthread_create(&lt, -1,
initial_lthread, (void *) NULL); seems to be not run. I put a breakpoint
inside initial_lthread() but the execution does not stop on the breakpoint.

My configuration:
- Linux Debian 8
- dpdk v18.05.1
- NUMA node0 CPU(s):     0-11,24-35
- NUMA node1 CPU(s):     12-23,36-47

Would someone know how to run ligthweight threads with
rte_eal_remote_launch( ) ?

Regards,
ikuzar
