Subject: [PATCH v11 04/21] hw/core: Support module-id in numa configuration
Date: Wed, 24 Apr 2024 23:49:12 +0800 [thread overview]
Message-ID: <20240424154929.1487382-5-zhao1.liu@intel.com> (raw)
In-Reply-To: <20240424154929.1487382-1-zhao1.liu@intel.com>
Module is a level above the core, thereby supporting numa
configuration on the module level can bring user more numa flexibility.
This is the natural further support for module level.
Add module level support in numa configuration.
