Bug ID: 446
Summary: rte_lcore_index(-1) returns invalid data for non DPDK
thread.
Product: DPDK
Version: 20.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: [email protected]
Reporter: [email protected]Target Milestone: ---
Calling rte_lcore_index() with -1 as lcore returns the relative index of the current lcore in the cpuset. But if called from a non-DPDK thread the value is undefined. It ends up referencing outside lcore_config array and gets some other value. In our tests it got 253; but could be anything.
It is documented to return -1 on error. It does that if passed an lcore value outside the cpu set, it should return -1 if run in non-DPDK thread as well.
