Subject: [PATCH] eventdev/timer: fix adapter stop function
Date: Thu, 22 Sep 2022 02:53:11 -0500	[thread overview]
Message-ID: <20220922075311.4127874-1-s.v.naga.harish.k@intel.com> (raw)

adapter_stop function is stopping the adapter service using
rte_service_runstate_set() api and waiting until
rte_service_may_be_active() api returns stopped state in an
infinite loop.

This results in hang issues if application calls
rte_service_lcore_stop() before adapter stop.

remove the state check after setting the service state which
avoids running into hang issues. This also makes timer adapter
stop inline with remaining adapters.

Fixes: 47d05b292820 ("eventdev: add timer adapter common code")
