[Qemu-devel] [PATCH V1 RESEND 0/6] Build ACPI Heterogeneous Memory Attribute Table (HMAT)

[Liu Jingqi]

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.

Liu Jingqi (6):
  hmat acpi: Build Memory Subsystem Address Range Structure(s) in ACPI
    HMAT
  hmat acpi: Build System Locality Latency and Bandwidth Information
    Structure(s) in ACPI HMAT
  hmat acpi: Build Memory Side Cache Information Structure(s) in ACPI
    HMAT
  numa: Extend the command-line to provide memory latency and bandwidth
    information
  numa: Extend the command-line to provide memory side cache information
  hmat acpi: Implement _HMA method to update HMAT at runtime
