Hello, I would like to kill the primary process and then promote the seconary process to primary. After checking the apis in dpdk source code, I think dpdk doesn't provide the promote interface. Any one knows why we don't have this interface? No usage scenario? or it's impossible to implement?
Bellow is my scenario: I would like to upgrade my application(openvswitch). Because the hugepage initialization and dev probe is expensive, the application down time is very long(could be more than 10 seconds). So I would like to launch the new application(upgrade version) as secondary process, while keep the old application still running. New application shares memory from old application, so it can use the hugepage and already probed devices. Imediately old process is killed, new application starts forward packets. After old process(primary process) is killed, we would like to promote the new process from secondary to primary. Thanks, Cheng
