opencl: bugfix: missing increment of ref_count in ggml_backend_opencl_init() - #26162
Merged
Conversation
Incrementing `ref_count` at the beginning is important later in the `free()` method of the `ggml_backend_opencl_context` at program end. If we do not increment the `ref_count`, the result would be -1 here, and consequently, the profiling data would not be flushed and written. ( #ifdef GGML_OPENCL_PROFILING )

Just as a note, this fixes a legacy API; now applications will likely go through the new backend API. But the fix does make sense. |

This is important later in the
free()method ofggml_backend_opencl_contextat program end.If we do not increment the
ref_count, the result would be -1 here, and consequently, some parts offree()would not executed. For example the profiling data would not be flushed and written. ( #ifdef GGML_OPENCL_PROFILING )Requirements
