[Qemu-devel] [PATCH v5 0/8] Build ACPI Heterogeneous Memory Attribute Table (HMAT)
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.
