This four patches define CDM node with HugeTLB & Buddy allocation isolation. Please refer to the last RFC posting mentioned here for more details. The RFC series has been split for easier review process. The next part of the work like VM flags, auto NUMA and KSM interactions with tagged VMAs will follow later. RFC https://lkml.org/lkml/2017/1/29/198 Changes in V3: * Changed is_coherent_node interface into is_cdm_node * Fixed the CDM allocation leak problem when cpuset is enabled on the system which requires changes to get_page_from_freelist function and verifying that the non NULL nodemask is indeed the requested one not becuase of the cpuset override on the way Changes in V2: (https://lkml.org/lkml/2017/2/10/183) * Removed redundant nodemask_has_cdm() check from zonelist iterator * Dropped the nodemask_had_cdm() function itself * Added node_set/clear_state_cdm() functions and removed bunch of #ifdefs * Moved CDM helper functions into nodemask.h from node.h header file * Fixed the build failure by additional CONFIG_NEED_MULTIPLE_NODES check Previous V1: (https://lkml.org/lkml/2017/2/8/329) Anshuman Khandual (4): mm: Define coherent device memory (CDM) node mm: Enable HugeTLB allocation isolation for CDM nodes mm: Add new parameter to get_page_from_freelist() function mm: Enable Buddy allocation isolation for CDM nodes Documentation/ABI/stable/sysfs-devices-node | 7 +++ arch/powerpc/Kconfig | 1 + arch/powerpc/mm/numa.c | 7 +++ drivers/base/node.c | 6 +++ include/linux/nodemask.h | 58 ++++++++++++++++++++- mm/Kconfig | 4 ++ mm/hugetlb.c | 25 +++++---- mm/memory_hotplug.c | 3 ++ mm/page_alloc.c | 81 +++++++++++++++++++++-------- 9 files changed, 160 insertions(+), 32 deletions(-) -- 2.9.3 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
