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 V17 patches link: https://patchwork.kernel.org/cover/11257319/ Changelog: v18: - 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) v17: - Add check when user input latency or bandwidth 0, the lb_info_provided should also be 0. Because in ACPI 6.3 5.2.27.4, 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) v16: - 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) v15: - Add a new patch to refactor do_strtosz() (Eduardo) - Make tests without breaking CI (Michael) v14: - Reuse the codes of do_strtosz to build qemu_strtotime_ns (Eduardo) - 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 v13: - 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 v12: - Fix a bug that a memory-only node without initiator setting doesn't report error. (reported by Danmei Wei) - Fix a bug that if HMAT is enabled and without hmat-lb setting, QEMU will crash. (reported by Danmei Wei) v11: - Move numa option patches forward. - Add num_initiator in Numa_state to record the number of initiators. - Simplify struct HMAT_LB_Info, use uint64_t array to store data. - Drop hmat_get_base(). - Calculate base in build_hmat_lb().
