[Qemu-devel] [PATCH v7 00/11] Build ACPI Heterogeneous Memory Attribute Table (HMAT)

[Tao Xu]

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 Memory Proximity Domain.
The software is expected to use HMAT information as hint for optimization.

In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report
the platform's HMAT tables.

Changelog:
v7:
    - Defer 11-13 of patch v6, because the driver of _HMA hasn't been
      implemented in kernel driver
    - Drop the HMAT_LB_MEM_CACHE_LAST_LEVEL which is not used in
      ACPI 6.3 (Jonathan)
    - Add bit mask in flags of hmat-lb (Jonathan)
    - Add a marco to indicate the type is latency or bandwidth (Jonathan)
v6:
    - Rebase to upstream, move numa globals in arm/sbsa-ref
    - When used once or twice in the function, use
      ms->numa_state->num_nodes(numa_info) directly (Igor)
    - Correct some mistakes
    - Use once monitor_printf in hmp_info_numa (Igor)
    - Add new patch to extend CLI of "-numa node" option to indicate the
      initiator numa node-id (Dan)
    - Update to ACPI 6.3 (Jonathan)
    - Add QMP interface to update HMAT at runtime (Igor)
    - Add test cases for ACPI HMAT
