2024-03-29vlib: improve automatic core pinninghsandid1-7/+64
Type: feature Auto core pinning now fetches vpp cpu affinity list using pthread api. This enables us to do core-pinning in environments where the host cpu list does not necessarily align with cpus available to vpp Change-Id: Ife8c2a2351c08c5c6c4fdf7c729eeff2697bc39a Signed-off-by: hsandid <halsandi@cisco.com>
