When our customers configure the CPU Pinning to Compute nodes, they usually refer to the below documentation.

Chapter 4. Configuring CPUs on Compute nodes

However, the below issue will be happened when deploy overcloud to apply the changes after following the steps mentioned in the above link due to lack of `TunedProfileName: "cpu-partitioning"` heat parameter.

FATAL | Fail if tuned profile conf is absent but isolated cores is provided | compute-XX | error={"changed": false, "msg": "Tuned profile conf file is not available to configure isolated cores"} 

This issue has been reported some times from our customers and there is the below KCS for the issue.

The overcloud deploy configured with CPU pinning fails with "Tuned profile conf file is not available to configure isolated cores"

Therefore, I guess a step to add `TunedProfileName: "cpu-partitioning"` parameter to a environment file should be mentioned in the documentation to avoid unneccessary failure.
