Subject: [PATCH v4 0/3] coresight-tnoc: Add support for Interconnect TNOC
Date: Sun, 31 Aug 2025 23:58:12 -0700 [thread overview]
Message-ID: <20250831-itnoc-v4-0-f0fb0ef822a5@oss.qualcomm.com> (raw)
This patch series adds support for the Qualcomm CoreSight Interconnect TNOC
(Trace Network On Chip) block, which acts as a CoreSight graph link forwarding
trace data from subsystems to the Aggregator TNOC. Unlike the Aggregator TNOC,
this block does not support aggregation or ATID assignment.
