Add a new sort option "data_page_size" for --mem-mode sort. With this option applied, perf can sort and report by sample's data page size. Here is an example: perf report --stdio --mem-mode --sort=comm,symbol,phys_daddr,data_page_size # To display the perf.data header info, please use # --header/--header-only options. # # # Total Lost Samples: 0 # # Samples: 9K of event 'mem-loads:uP' # Total weight : 9028 # Sort order : comm,symbol,phys_daddr,data_page_size # # Overhead Command Symbol Data Physical # Address # Data Page Size # ........ ....... ............................ # ...................... ...................... # 11.19% dtlb [.] touch_buffer [.] 0x00000003fec82ea8 4K 8.61% dtlb [.] GetTickCount [.] 0x00000003c4f2c8a8 4K 4.52% dtlb [.] GetTickCount [.] 0x00000003fec82f58 4K 4.33% dtlb [.] __gettimeofday [.] 0x00000003fec82f48 4K 4.32% dtlb [.] GetTickCount [.] 0x00000003fec82f78 4K 4.28% dtlb [.] GetTickCount [.] 0x00000003fec82f50 4K 4.23% dtlb [.] GetTickCount [.] 0x00000003fec82f70 4K 4.11% dtlb [.] GetTickCount [.] 0x00000003fec82f68 4K 4.00% dtlb [.] Calibrate [.] 0x00000003fec82f98 4K 3.91% dtlb [.] Calibrate [.] 0x00000003fec82f90 4K 3.43% dtlb [.] touch_buffer [.] 0x00000003fec82e98 4K 3.42% dtlb [.] touch_buffer [.] 0x00000003fec82e90 4K 0.09% dtlb [.] DoDependentLoads [.] 0x000000036ea084c0 2M 0.08% dtlb [.] DoDependentLoads [.] 0x000000032b010b80 2M Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Andi Kleen <ak@linux.intel.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Stephane Eranian <eranian@google.com> Cc: Will Deacon <will@kernel.org> Link: http://lore.kernel.org/lkml/20201216185805.9981-3-kan.liang@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
