# TODO(b/267675642): this is the sample code shared by QNX to convert traceprinter
|
|
# output to json file. We will clean it up and improve it as we make changes.
|
|
# For example:
|
|
# Using stdlib to do the JSON conversion.
|
|
# Add helper function for timestamp conversion.
|
|
#
|
|
# Usage:
|
|
# python3 qnx_perfetto.py qnx_traceprinter_output_file qnx_trace.json
|
