![]() opal_mpipl_query_tag() takes a pointer to a 64-bit value, which firmware writes a value to. As OPAL is traditionally big endian this value will be big endian. This can be confirmed by looking at the implementation in skiboot: static uint64_t opal_mpipl_query_tag(enum opal_mpipl_tags tag, __be64 *tag_val) { ... *tag_val = cpu_to_be64(opal_mpipl_tags[tag]); return OPAL_SUCCESS; } Fix the declaration to annotate that the value is big endian.
