# Example prj.conf for using Percepio TraceRecorder with Zephyr
#
# This example provides snapshot tracing, but can be modified for other setups.
#
# Important notes before use:
#
# * In Tracealyzer, open File -> Settings -> Project Settings -> Definition File Paths
#   and add the path to your Zephyr build folder (containing syscalls-v<VERSION>.xml)
#
# * A full rebuild (--pristine) is recommended after enabling TraceRecorder, if you
#   have changed the tracing settings, or if Zephyr has been updated.

# REQUIRED SETTINGS
# Ensure you have the following in your prj.conf.

# Master switch for Zephyr tracing.
CONFIG_TRACING=y

# Use Percepio TraceRecorder as tracing backend
CONFIG_PERCEPIO_TRACERECORDER=y

# Ensure the TraceRecorder control task has sufficient stack
CONFIG_PERCEPIO_TRC_CFG_CTRL_TASK_STACK_SIZE=1024

# Use the RingBuffer streamport (tracing to RAM buffer, for snapshots)
CONFIG_PERCEPIO_TRC_CFG_STREAM_PORT_RINGBUFFER=y
# Or select another option:
# CONFIG_PERCEPIO_TRC_CFG_STREAM_PORT_RTT=y
# CONFIG_PERCEPIO_TRC_CFG_STREAM_PORT_ITM=y
# CONFIG_PERCEPIO_TRC_CFG_STREAM_PORT_FILE=y

# If you want to stream the trace data via SEGGER J-Link (RTT), please refer
# to our guide at https://percepio.com/troubleshoot-j-link-rtt


# RECOMMENDED SETTINGS

# We recommend to disable the "Syscall" event category. 
# This is kind of a "catch-all" for events lacking bespoke
# instrumentation. Kernel events like mutex and semaphore 
# events are still recorded.
CONFIG_TRACING_SYSCALL=n

# Disables "polling" events, sometimes frequent and costly.
CONFIG_TRACING_POLLING=n

# Sets the size of the RingBuffer trace buffer (in bytes)
CONFIG_PERCEPIO_TRC_CFG_STREAM_PORT_RINGBUFFER_SIZE=4096
