From: Gang Li <ligang.bdlg@xxxxxxxxxxxxx> Inspired by these patches [1][2], this series aims to speed up the initialization of hugetlb during the boot process through parallelization. It is particularly effective in large systems. On a machine equipped with 1TB of memory and two NUMA nodes, the time for hugetlb initialization was reduced from 2 seconds to 1 second. In the future, as memory continues to grow, more and more time can be saved. This series currently focuses on optimizing 2MB hugetlb. Since gigantic pages are few in number, their optimization effects are not as pronounced. We may explore optimizations for gigantic pages in the future. Thanks, Gang Li Gang Li (4): hugetlb: code clean for hugetlb_hstate_alloc_pages hugetlb: split hugetlb_hstate_alloc_pages hugetlb: add timing to hugetlb allocations on boot hugetlb: parallelize hugetlb page allocation mm/hugetlb.c | 191 ++++++++++++++++++++++++++++++++++++--------------- 1 file changed, 134 insertions(+), 57 deletions(-) -- 2.20.1
