Bug ID: 1935
Summary: rte_lcore_to_cpu_id returns incorrect cpu-id when
lcore-map or re-map lcore option used
Product: DPDK
Version: 26.03
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---

DPDK: 26.03
test application: modified examples/helloworld cmd:
working: ./build/helloworld -l0,1,67,14,33
faulty-1: ./build/helloworld -l0,1,67,14,33 -R
faulty-2: ./build/helloworld -l0@8,1@18,2@67,3@14,4@33

expected behaviour: if there are eal args for remap or map lcore, the API (as per current understanding) should return the actual core on which it runs. API rte_lcore_cpuset returns a valid value in all cases.
