Subject: [RFC PATCH 19/44] eal: move iova mode and process type to runtime cfg
Date: Wed, 29 Apr 2026 17:58:11 +0100 [thread overview]
Message-ID: <20260429165845.2136843-20-bruce.richardson@intel.com> (raw)
In-Reply-To: <20260429165845.2136843-1-bruce.richardson@intel.com>
Move two more fields, iova_mode and process_type from old rte_config to
eal_runtime_state struct.
