[PATCH OLK-6.6 0/4] memory tiering: calculate abstract distance based on ACPI HMAT
by Tong Tiangen 04 Feb '24

04 Feb '24

We have the explicit memory tiers framework to manage systems with multiple types of memory, e.g., DRAM in DIMM slots and CXL memory devices. Where, same kind of memory devices will be grouped into memory types, then put into memory tiers. To describe the performance of a memory type, abstract distance is defined. Which is in direct proportion to the memory latency and inversely proportional to the memory bandwidth. To keep the code as simple as possible, fixed abstract distance is used in dax/kmem to describe slow memory such as Optane DCPMM. To support more memory types, in this series, we added the abstract distance calculation algorithm management mechanism, provided a algorithm implementation based on ACPI HMAT, and used the general abstract distance calculation interface in dax/kmem driver. So, dax/kmem can support HBM (high bandwidth memory) in addition to the original Optane DCPMM. Huang Ying (4): memory tiering: add abstract distance calculation algorithms management acpi, hmat: refactor hmat_register_target_initiators() acpi, hmat: calculate abstract distance with HMAT dax, kmem: calculate abstract distance with general interface drivers/acpi/numa/hmat.c | 146 ++++++++++++++++++++----------- drivers/dax/kmem.c | 62 ++++++++++--- include/linux/memory-tiers.h | 39 +++++++++ mm/memory-tiers.c | 165 ++++++++++++++++++++++++++++++++++- 4 files changed, 344 insertions(+), 68 deletions(-) -- 2.25.1

[PATCH OLK-6.6 0/4] Introduce page eject for arm64
by Wupeng Ma 04 Feb '24

04 Feb '24

From: Ma Wupeng <mawupeng1(a)huawei.com> Page ejection is achieved by soft_offline_page and unpoison_memory. A linked list is maintained to log the pfns which are offlined by this module. Only the pfns present in the list is allowed to go online. The follow sysfs is introduced to online/offline page via this module, since there is a internal linked list to record all offlined pages, remove_page is introduce to remove this page from list. - /sys/kernel/page_eject/online_page - /sys/kernel/page_eject/offline_page - /sys/kernel/page_eject/remove_page Ma Wupeng (4): mm/hwpoison: Export symbol soft_offline_page mm/memory-failure: introduce soft_online_page mm: page_eject: Introuduce page ejection config: update defconfig for PAGE_EJECT arch/arm64/configs/openeuler_defconfig | 1 + drivers/ras/Kconfig | 10 + drivers/ras/Makefile | 1 + drivers/ras/page_eject.c | 249 +++++++++++++++++++++++++ include/linux/mm.h | 1 + mm/memory-failure.c | 40 ++-- 6 files changed, 288 insertions(+), 14 deletions(-) create mode 100644 drivers/ras/page_eject.c -- 2.25.1
