* Modified perfetto output for HIP stream display * Moved stream_map file location and changed perfetto output names Private_Segment_Size and Group_Segment_Size to Scratch_Size and LDS_Block_Size respectively * Used const_cast to remove const modifier on void* * Reverted stream_map changes, now using tool_metadata map to track mapping between stream ptrs and stream IDs * Removed buffer tracing args in perfetto, added tool_...hip buffer record struct that stores the HIP stream ID for display purposes * Updated rocpd perfetto.cpp to reflect stream changes. Still need to add vgpr values and stream ID for HIP API * Changes pass-by const reference to pass-by const value
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=1to obtain kernel traceROCPROF_HSA_API_TRACE=1to 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 pathROCPROF_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.
