Subject: Detecting if rte_eal_init() has already been called
Date: Wed, 27 Dec 2023 03:54:12 +0000	[thread overview]
Message-ID: <OSZPR01MB774835807CDC015C94EDB655BC9FA@OSZPR01MB7748.jpnprd01.prod.outlook.com> (raw)

Hi all,

I'm loading two semi-independent DPDK-ready shared libraries into a master process. If both call rte_eal_init() I get a fatal error about calling it a second time. I tried the rte_eal_primary_proc_alive(NULL) API, but that failed to detect that the other library had already called rte_eal_init().

I feel there should be a simple rte_eal_is_inited()-like API somewhere, but I cannot find it.

Note, I cannot easily change the master process as it is a third-party tool that knows nothing about DPDK. For now I am just relying on the order of loading the libraries and skipping rte_eal_init() on the second.

Thanks,
Ken
