# 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. rocprofv3 supports both
|
|
launching new applications and attaching to existing
|
|
processes using the `--attach`/`--pid`/`-p` options.
|
|
|
|
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.
