Arm Embedded Trace Extension(ETE) is a per CPU trace component that
|
|
allows tracing the CPU execution. It overlaps with the CoreSight ETMv4
|
|
architecture and has extended support for future architecture changes.
|
|
The trace generated by the ETE could be stored via legacy CoreSight
|
|
components (e.g, TMC-ETR) or other means (e.g, using a per CPU buffer
|
|
Arm Trace Buffer Extension (TRBE)). Since the ETE can be connected to
|
|
legacy CoreSight components, a node must be listed per instance, along
|
|
with any optional connection graph as per the coresight bindings.
