Subject: [PATCH v1] binder: transaction latency tracking for user build
Date: Tue, 4 Feb 2020 17:15:14 +0800 [thread overview]
Message-ID: <1580807715-26609-1-git-send-email-Frankie.Chang@mediatek.com> (raw)
Record start/end timestamp to binder transaction.
When transaction is completed or transaction is free,
it would be checked if transaction latency over threshold (2 sec),
if yes, printing related information for tracing.
