Subject: [PATCH] eal: stop iteration after lcore info is processed
Date: Wed, 1 Nov 2023 15:20:53 +0800 [thread overview]
Message-ID: <20231101072053.1319697-1-ruifeng.wang@arm.com> (raw)
Telemetry iterates on lcore ID to collect info of a specific lcore.
Since only one lcore is processed at a time, the iteration can stop
when a matching lcore is found.
Fixes: f2b852d909f9 ("eal: add lcore info in telemetry")
