Umesh, I came across these in GuC documentation: guc_pcv1_context_parameters_set_h2g_data_t::context_id guc_pcv2_context_parameters_set_h2g_data_t::context_id Also in the code we have in prepare_context_registration_info_v70 'ctx_id = ce->guc_id.id' which seems to be assigned in new_guc_id. So wondering if this is what we need and we already have it? Thanks. -- Ashutosh
