 ## Supported platforms
 
 At initial release, the AMD SMI library will support Linux bare metal and Linux virtual machine guest for AMD GPUs. In the future release, the library will be extended to support AMD EPYC™ CPUs.
 
 AMD SMI library can run on AMD ROCm supported platforms, please refer to [List of Supported Operating Systems and GPUs](https://rocm.docs.amd.com/en/latest/release/gpu_os_support.html)

It is important to note that a device may end up with a different device handles after restart application, so a device handle should not be relied upon to be constant over process.

 ## Hello AMD SMI
 
 The only required AMD-SMI call for any program that wants to use AMD-SMI is the `amdsmi_init()` call. This call initializes some internal data structures that will be used by subsequent AMD-SMI calls. In the call, a flag can be passed if the application is only interested in a specific device type.
