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 V14 patches link: https://patchwork.kernel.org/cover/11214887/ Changelog: 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(). v10: - Add qemu_strtotime_ps() to convert strings with time suffixes to numbers, and add some tests for it. - Add qapi buildin type time, and add some tests for it. - Add machine oprion properties "-machine hmat=on|off" for enabling or disabling HMAT in QEMU.
