[PATCH RESEND v20 0/8] Build ACPI Heterogeneous Memory Attribute Table (

From: Tao Xu
Subject: [PATCH RESEND v20 0/8] Build ACPI Heterogeneous Memory Attribute Table (HMAT)
Date: Fri, 13 Dec 2019 09:19:21 +0800

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.

The V19 patches link:

    - Resend to fix the wrong target in pc_hmat_erange_cfg()
    - Use g_assert_true and g_assert_false to replace g_assert
      (Thomas and Markus)
    - Rename assoc as associativity, update the QAPI description (Markus)
    - Disable cache level 0 in hmat-cache option (Igor)
    - Keep base and bitmap unchanged when latency or bandwidth
      out of range
    - Fix the broken CI case when user input latency or bandwidth
      less than required.
    - Add description about the machine property 'hmat' in commit
      message (Markus)
    - Update the QAPI comments
    - Add a check for no memory side cache
    - Add some fail cases for hmat-cache when level=0
    - Defer patches 01/14~06/14 of V17, use qapi type uint64 and
      only nanosecond for latency (Markus)
    - Rewrite the lines over 80 characters(Igor)
    - Add check when user input latency or bandwidth 0, the
      lb_info_provided should also be 0. Because in ACPI 6.3,
      0 means the corresponding latency or bandwidth information is
      not provided.
    - Fix the infinite loop when node->latency is 0.
    - Use NumaHmatCacheOptions to replace HMAT_Cache_Info (Igor)
    - Add check for unordered cache level input (Igor)
    - Add some fail test cases (Igor)
    - Add and use qemu_strtold_finite to parse size, support full
      64bit precision, modify related test cases (Eduardo and Markus)
    - Simplify struct HMAT_LB_Info and related code, unify latency
      and bandwidth (Igor)
    - Add cross check with hmat_lb data (Igor)
    - Fields in Cache Attributes are promoted to uint32_t before
      shifting (Igor)
    - Add case for QMP build HMAT (Igor)
    - Add a new patch to refactor do_strtosz() (Eduardo)
    - Make tests without breaking CI (Michael)
    - Reuse the codes of do_strtosz to build qemu_strtotime_ns
    - Squash patch v13 01/12 and 02/12 together (Daniel and Eduardo)
    - Drop time unit picosecond (Eric)
    - Use qemu ctz64 and clz64 instead of builtin function
    - Modify some text description
    - Drop "initiator_valid" field in struct NodeInfo
    - Reuse Garray to store the raw bandwidth and bandwidth data
    - Calculate common base unit using range bitmap
    - Add a patch to alculate hmat latency and bandwidth entry list
    - Drop the total_levels option and use readable cache size
    - Remove the unnecessary head file
    - Use decimal notation with appropriate suffix for cache size
