ippStsNoOperationInDll

This warning means the dynamic-library version of the IPP function did not execute work. It is a runtime dispatch or packaging signal, not a statement about the mathematical validity of source data.

It is especially important in wrappers that treat any non-negative IppStatus as harmless. The output buffer may be unchanged even though the call returned a warning rather than a negative error.

Diagnostic focus

Check whether the selected IPP DLL or shared object is a stub, placeholder, or incomplete domain library.
Do not consume destination buffers without knowing whether the primitive wrote them.
Log the library version and resolved binary path.
