title: Log the kernel collapsing normal pages into a huge page name: hugepage_collapse.stp version: 1.0 author: William Cohen keywords: memory subsystem: memory status: production exit: user-controlled output: sorted-list scope: system-wide description: The kernel may attempt to group many normal sized pages into a single huge page to improve TLB performance. This operation may take a significant amount of time and affect program performance. You can identify if huge page collapse operations are occurring with the systemtap hugepage_collapse.stp script. test_support: stap -l 'kernel.function("collapse_huge_page")' test_check: stap -p4 hugepage_collapse.stp test_installcheck: stap hugepage_collapse.stp -T 1
