The bug was reproduced like this. In terminal #1, run command: sudo amd-smi ras --cper --gpu 6 --severity all --folder /tmp/cper_dump --follow In terminal #2, inject errors: while true; do sudo amdgpuras -b 7 -s 1 -m 6 -t 2; sleep 2; done The terminal #1 starts dumping cper entry information that it captures. After 20 entries have been captured, open terminal #3 and run same command as terminal #1: sudo amd-smi ras --cper --gpu 6 --severity all --folder /tmp/cper_dump --follow From terminal #3, there will be no output, even when terminal #1 continues capturing and printing information. The fix: Since we already have more than 20 CPER entries available in the GPU buffer, when we run the command from terminal #3 to start capturing from the beginning and pass 20 buffers to copy entries to, the C++ API returns a code saying there is more data available. The Python CLI should not treat this as an error, but should continue to print what the API returned. --------- Signed-off-by: Oosman Saeed <oossaeed@amd.com>
AMD SMI CLI tool
A command line tool for manipulating and monitoring the amdgpu kernel;
amd-smi is intended to replace and deprecate the existing
rocm-smi CLI tool.
When using the CLI tool, you should have at least one AMD GPU and the driver installed.
Note
The AMD SMI CLI tool is provided as an example code to aid the development of telemetry tools. The Python or C++ library is recommended as a robust data source.
