We wanted to know is there any Utilities available to fetch the following properties of a AMD GPU card in Linux OS ?


1) Serial Number

2) Maximum Clock Speed of a AMD card

3) Total number of cores allocated for a AMD GPU card


We have tried the following methods but could not be successful in fetching the informations:


1) command line utility :  /opt/rocm/opencl/bin/x86_64/clinfo


    Although this gives some information, there is no matching informations between clinfo output and sysfs values.

    Also the "Device Topology" value in clinfo does not contain the Domain value of PCI information. It contains only B,D and F values


2) command line utility :  /opt/rocm/bin/rocm-smi


3) Using sysfs attributes ( Ex: /sys/bus/pci/drivers/amdgpu/"PCI LOCATION"/...... )
