From: Kan Liang <kan.liang@linux.intel.com>
Current perf can report both virtual addresses and physical addresses, but not the page size. Without the page size information of the utilized page, users cannot decide whether to promote/demote large pages to optimize memory usage.
The kernel patches have been merged into tip perf/core branch, commit 8d97e71811aa ("perf/core: Add PERF_SAMPLE_DATA_PAGE_SIZE") commit 76a5433f95f3 ("perf/x86/intel: Support PERF_SAMPLE_DATA_PAGE_SIZE") commit 4cb6a42e4c4b ("powerpc/perf: Support PERF_SAMPLE_DATA_PAGE_SIZE") commit 995f088efebe ("perf/core: Add support for PERF_SAMPLE_CODE_PAGE_SIZE") commit 51b646b2d9f8 ("perf,mm: Handle non-page-table-aligned hugetlbfs")
and Peter's perf/core branch commit 524680ce47a1 ("mm/gup: Provide gup_get_pte() more generic") commit 44a35d6937d2 ("mm: Introduce pXX_leaf_size()") commit 2f1e2f091ad0 ("perf/core: Fix arch_perf_get_page_size()") commit 7649e44aacdd ("arm64/mm: Implement pXX_leaf_size() support") commit 1df1ae7e262c ("sparc64/mm: Implement pXX_leaf_size() support")
This patch set is to enable the page size support in user tools.
