X-Received-From: 192.55.52.43 Subject: [Qemu-devel] [PATCH v4 00/11] Build ACPI Heterogeneous Memory Attribute Table (HMAT) X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: pbonzini@redhat.com, tao3.xu@intel.com, jingqi.liu@intel.com, qemu-devel@nongnu.org, rth@twiddle.net Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" This series of patches will build Heterogeneous Memory Attribute Table (HMAT) according to the command line. The ACPI HMAT describes the memory attributes, such as memory side cache attributes and bandwidth and latency details, related to the System Physical Address (SPA) Memory Ranges. The software is expected to use this information as hint for optimization. OSPM evaluates HMAT only during system initialization. Any changes to the HMAT state at runtime or information regarding HMAT for hot plug are communicated using the _HMA method.
