Benjamin Welton 4f05850efd [SWDEV-484495] Fix int truncation in CSV output (#1098)
CSV output truncates doubles to ints when it shouldn't. Derived metrics
are (mostly) doubles and lose precision (or become worthless) if treated
as an int. Converted these to double to match the format we return from
rocprof-sdk.

ROCProfiler Tool Library

This is a tool that gets registered with the rocprofiler to obtain its services. The tool is built as a shared library and is named as rocprofiler-sdk-tool. The library can be preloaded using LD_PRELOAD to facilitate its registration as a tool with the rocprofiler.

The user through rocprofv3 script can select the options to obtain tracing and counter collection services from the rocprofiler.

Currently, this tool supports kernel trace and the hsa-api trace. The tool uses the following environment variables to read the user choices.

  • ROCPROF_KERNEL_TRACE=1 to obtain kernel trace
  • ROCPROF_HSA_API_TRACE=1 to obtain hsa api trace

The user can also specify the output filename and output file path to which the traces are written to.

  • ROCPROF_OUTPUT_PATH=<directory> to set the output directory path
  • ROCPROF_OUTPUT_FILE_NAME=<filename-without-extension> to set the output file name

CHANGELOG

The tool design is similar to its earlier versions. However, not all features that the earlier versions supported are supported by this tool.
