rocm_smi.h File Reference
The rocm_smi library api is new, and therefore subject to change either at the ABI or API level. Instead of marking every function prototype as "unstable", we are instead saying the API is unstable (i.e., changes are possible) while the major version remains 0. This means that if the API/ABI changes, we will not increment the major version to 1. Once the ABI stabilizes, we will increment the major version to 1, and thereafter increment it on all ABI breaks.

Detailed Description
The rocm_smi library api is new, and therefore subject to change either at the ABI or API level. Instead of marking every function prototype as "unstable", we are instead saying the API is unstable (i.e., changes are possible) while the major version remains 0. This means that if the API/ABI changes, we will not increment the major version to 1. Once the ABI stabilizes, we will increment the major version to 1, and thereafter increment it on all ABI breaks.
Main header file for the ROCm SMI library. All required function, structure, enum, etc. definitions should be defined in this file.

| RSMI_EVNT_XGMI_0_NOP_TX | NOPs sent to neighbor 0. |
| RSMI_EVNT_XGMI_0_REQUEST_TX | Outgoing requests to neighbor 0 |
