Are there any processor tracing support on Jetson AGX Orin

Hi,

Coresight tracing sources (STM and ETM) and ETF sink are supported in Linux in Orin.

The corresponding nodes in device tree need to be enabled: hardware/nvidia/soc/t23x/kernel-dts/tegra234-soc/tegra234-soc-coresight.dtsi

Below kernel config also needs to be enabled:

CONFIG_CORESIGHT=y
CONFIG_CORESIGHT_LINKS_AND_SINKS=y
CONFIG_CORESIGHT_LINK_AND_SINK_TMC=y
CONFIG_CORESIGHT_STM=y
CONFIG_CORESIGHT_SOURCE_ETM4X=y

ETR sink is not accessible currently.
