Subject: [PATCH v3 6/8] tests/intel/xe_eudebug_online: use xe_query helpers for query GT topology
Date: Mon, 17 Nov 2025 11:47:44 +0100	[thread overview]
Message-ID: <20251117-xe_query_helpers-v3-6-25d984ae58cb@intel.com> (raw)
In-Reply-To: <20251117-xe_query_helpers-v3-0-25d984ae58cb@intel.com>

Using xe_query_device and xe_for_each_topology_mask simplifies the code.
