[PATCH OLK-6.6 v2 0/6] Introduce dynamic pool feature part 2
by Liu Shixin 29 Mar '24

29 Mar '24

v1->v2: Fix compile error. This part include: 1. Compatible with memory reliable feature[1-3]. 2. Compatible with memory migration[4] 3. Fix an incorrect set of subpool[5]. 4. Make the lock in dynamic pool irq safe[6]. Liu Shixin (6): mm/dynamic_pool: Stop alloc reliable page from dynamic pool mm/mem_reliable: Treat page from dhugetlb pool as unreliable page mm/mem_reliable: Fallback to dpool if reliable memory is not enough mm/dynamic_pool: skip unexpected migration mm/dynamic_pool: don't set subpool for page from dynamic pool mm/dynamic_pool: disable irq for dynamic_pool lock include/linux/dynamic_pool.h | 6 ++ include/linux/mem_reliable.h | 3 + mm/compaction.c | 4 ++ mm/dynamic_pool.c | 112 +++++++++++++++++++---------------- mm/hugetlb.c | 3 +- mm/migrate.c | 7 +++ mm/page_alloc.c | 27 +++++++++ mm/page_isolation.c | 9 ++- 8 files changed, 118 insertions(+), 53 deletions(-) -- 2.25.1

[PATCH OLK-6.6] userfaultfd: early return in dup_userfaultfd()

29 Mar '24

From: ZhangPeng <zhangpeng362(a)huawei.com> maillist inclusion category: performance bugzilla: https://gitee.com/openeuler/kernel/issues/I9CKXN CVE: NA Reference: https://lore.kernel.org/all/20240327090835.3232629-1-zhangpeng362@huawei.co… -------------------------------- When vma->vm_userfaultfd_ctx.ctx is NULL, vma->vm_flags should have cleared __VM_UFFD_FLAGS. Therefore, there is no need to down_write or clear the flag, which will affect fork performance. Fix this by returning early if octx is NULL in dup_userfaultfd(). By applying this patch we can get a 1.3% performance improvement for lmbench fork_prot.

[PATCH OLK-6.6 v3 00/18] Mitigate a vmap lock contention
by Peng Zhang 29 Mar '24

29 Mar '24

From: ZhangPeng <zhangpeng362(a)huawei.com> This patch set includes two patch sets: Mitigate a vmap lock contention and mm/vmalloc: lock contention optimization under multi-threading. In high-concurrency scenarios such as the "/test_vmalloc.sh run_test_mask=7 nr_threads=64" scenario, the performance is improved by more than 10x. The run time was reduced from 18m45.268s to 1m45.066s. Changelog: v2->v3: - Fix commit format warning v1->v2: - Remove 2 maillist inclusion patches - Merge patch 21 to resolve the conflict in patch 16 Alexei Starovoitov (3): mm: Enforce VM_IOREMAP flag and range in ioremap_page_range. mm: Introduce VM_SPARSE kind and vm_area_[un]map_pages(). mm: Introduce vmap_page_range() to map pages in PCI address space Baoquan He (2): mm/vmalloc: fix the unchecked dereference warning in vread_iter() mm/vmalloc: remove vmap_area_list Uladzislau Rezki (Sony) (13): mm: vmalloc: add va_alloc() helper mm: vmalloc: rename adjust_va_to_fit_type() function mm: vmalloc: move vmap_init_free_space() down in vmalloc.c mm: vmalloc: remove global vmap_area_root rb-tree mm: vmalloc: remove global purge_vmap_area_root rb-tree mm: vmalloc: offload free_vmap_area_lock lock mm: vmalloc: add a scan area of VA only once mm: vmalloc: support multiple nodes in vread_iter mm: vmalloc: support multiple nodes in vmallocinfo mm: vmalloc: set nr_nodes based on CPUs in a system mm: vmalloc: add a shrinker to drain vmap pools mm: vmalloc: improve description of vmap node layer mm: vmalloc: refactor vmalloc_dump_obj() function .../admin-guide/kdump/vmcoreinfo.rst | 8 +- arch/arm/mm/ioremap.c | 8 +- arch/arm64/kernel/crash_core.c | 1 - arch/loongarch/kernel/setup.c | 2 +- arch/mips/loongson64/init.c | 2 +- arch/powerpc/kernel/isa-bridge.c | 4 +- arch/riscv/kernel/crash_core.c | 1 - drivers/pci/pci.c | 4 +- include/linux/io.h | 7 + include/linux/vmalloc.h | 6 +- kernel/crash_core.c | 4 +- kernel/kallsyms_selftest.c | 1 - mm/nommu.c | 2 - mm/vmalloc.c | 1156 +++++++++++++---- 14 files changed, 914 insertions(+), 292 deletions(-) -- 2.25.1
