Subject: [PATCH v4 0/2] coresight: Add Coresight Trace Network On Chip driver
Date: Tue, 15 Apr 2025 17:25:38 +0800 [thread overview]
Message-ID: <20250415-trace-noc-v4-0-979938fedfd8@quicinc.com> (raw)
The Trace Network On Chip (TNOC) is an integration hierarchy which is a
hardware component that integrates the functionalities of TPDA and
funnels. It collects trace form subsystems and transfers to coresight
sink.
