# This script decodes Xtensa CPU trace dumps. It allows tracing the program
|
||||
# execution at instruction level.
|
||||
#
|
||||
# Some trivia about the Xtensa CPU trace (TRAX):
|
||||
# TRAX format mostly follows the IEEE-ISTO 5001-2003 (Nexus) standard.
|
||||
# The following Nexus Program Trace messages are implemented by TRAX:
|
||||
# - Indirect Branch Message
|
||||
# - Syncronization Message
|
||||
# - Indirect Branch with Synchronization Message
|
||||
# - Correlation Message
|
||||
# TRAX outputs compressed traces with 2 MSEO bits (LSB) and 6 MDO bits (MSB),
|
||||
# packed into a byte. MSEO bits are used to split the stream into packets and messages,
|
||||
# and MDO bits carry the actual data of the messages. Each message may contain multiple packets.
|
||||
#
|
||||
# This script can be used standalone, or loaded into GDB.
|
||||
# When used standalone, it dumps the list of trace messages to stdout.
|
||||
# When used from GDB, it also invokes GDB command to dump the list of assembly
|
||||
# instructions corresponding to each of the messages.
|
||||
#
|
||||
# Standalone usage:
|
||||
# traceparse.py <dump_file>
|
||||
#
|
||||
# Usage from GDB:
|
||||
# xtensa-esp32-elf-gdb -n --batch program.elf -x gdbinit
|
||||
# with the following gdbinit script:
|
||||
# set pagination off
|
||||
# set confirm off
|
||||
# add-symbol-file rom.elf <address of ROM .text section>
|
||||
# source traceparse.py
|
||||
# python parse_and_dump("/path/to/dump_file")
|
||||
#
|
||||
# Loading the ROM code is optional; if not loaded, disassembly for ROM sections of code
|
||||
# will be missing.

Setting up Python 3 as default for CentOS
