From 328720c594f235aa44c78fe360e8e6f31b5e989f Mon Sep 17 00:00:00 2001 From: Ruifeng Wang Date: Mon, 30 Aug 2021 16:04:12 +0800 Subject: [PATCH] examples/service_cores: fix lcore count check The example has various profiles to run services on specified number of lcores. Due to incorrect boundary condition, service can be dispatched to a core that does not exist. This puts main core into endless wait. Max available number of service cores is all detected lcores excluding main core.
