This > patch set introduces a function, rte_service_may_be_active(), to check > whether a stopped service is truly stopped. > > This is needed for flows that modify a resource that the service is > using; for example when stopping an eventdev, any event adapters and/or > scheduler service need to be quiesced first. > > This patch set also adds support for the event sw PMD's device stop flush > callback, which relies on this new mechanism to ensure that the > scheduler service is no longer active. > > v2: > - Move function to DPDK_18.08 block in rte_eal_version.map > - Fix signed vs. unsigned comparison compiler warning > > v3: > - Move function to EXPERIMENTAL block and add experimental tags > - Fix typo in function documentation > Applied series to dpdk-next-eventdev/master.
