Research direction

Start in source/loader/ze_loader.cpp around the existing to_string function linked in the issue, then inspect how loader-facing error handling is exposed. Done means consumers can obtain a meaningful string for an error code without duplicating the failure-name mapping.

Written by the indexing model from the issue text.

Description

Hi!

More often than not, error handling by the returned value takes the form of some macro checks that emit an exception or similar. E.g.,

#define L0_SAFE_CALL(call)                     \
  {                                            \
    auto status = (call);                      \
    if (status) {                              \
      throw some_exception(to_string(status)); \
    }                                          \
  }

To create a meaningful message it would be convenient to have a method in the loader that would take a single parameter - an error code - and return a string with the failure name. Even exposing the already-existing to_string function (https://github.com/oneapi-src/level-zero/blob/master/source/loader/ze_loader.cpp#L23) would be nice. This will make consumers not replicate it and avoid potential mismatches in case of any changes in the future.
