perf tools: Add a "dso_size" sort order
Add DSO size to perf report/top sort output list. This includes adding a map__size fn to map.h, which is approximately equal to the DSO data file_size: DSO file size map (end-start) file / (end-start) libwebkit2gtk-4.0.so.37.24.9 43260072 41295872 95% libglib-2.0.so.0.5400.1 1125680 1118208 99% libc-2.26.so 1960656 1925120 101% libdbus-1.so.3.14.13 309456 303104 102% Sample output: $ ./perf report -s dso_size,dso Samples: 2K of event 'cycles:uppp', Event count (approx.): 128373340 Overhead DSO size Shared Object 90.62% unknown [unknown] 2.87% 1118208 libglib-2.0.so.0.5400.1 1.92% 303104 libdbus-1.so.3.14.13 1.42% 1925120 libc-2.26.so 0.77% 41295872 libwebkit2gtk-4.0.so.37.24.9 0.61% 335872 libgobject-2.0.so.0.5400.1 0.41% 1052672 libgdk-3.so.0.2200.25 0.36% 106496 libpthread-2.26.so 0.29% 221184 dbus-daemon 0.17% 159744 ld-2.26.so 0.13% 49152 libwayland-client.so.0.3.0 0.12% 1642496 libgio-2.0.so.0.5400.1 0.09% 7327744 libgtk-3.so.0.2200.25 0.09% 12324864 libmozjs-52.so.0.0.0 0.05% 4796416 perf 0.04% 843776 libgjs.so.0.0.0 0.03% 1409024 libmutter-clutter-1.so Committer testing: To sort by DSO size, use: # perf report -F dso_size,dso,overhead -s dso_size <SNIP> 3465216 libdns-export.so.174.0.1 0.00% 3522560 libgc.so.1.0.3 0.00% 3538944 libbfd-2.29-13.fc27.so 0.59% 3670016 libunistring.so.2.1.0 0.00% 3723264 libguile-2.0.so.22.8.1 0.00% 3776512 libgio-2.0.so.0.5400.3 0.00% 3891200 libc-2.26.so 0.96% 3944448 libmozjs-17.0.so 0.00% 4218880 libperl.so.5.26.1 0.18% 4452352 libpython2.7.so.1.0 0.02% 4472832 perf 0.02% 4603904 git 0.01% 4751360 libcrypto.so.1.1.0g 0.00% 5005312 libslang.so.2.3.1 0.00% 7315456 libgtk-3.so.0.2200.26 0.09% 8818688 i965_dri.so 2.46% 8818688 i965_dri.so (deleted) 1.26% 12414976 libmozjs-52.so.0.0.0 0.03% 23642112 cc1 2.02% 27889664 [kernel.kallsyms] 25.41% 80834560 libxul.so (deleted) 15.68% 98078720 chrome 32.03% 1056964608 [kernel.kallsyms] 1.59% # Signed-off-by: Kim Phillips <kim.phillips@arm.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jin Yao <yao.jin@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Maxim Kuvyrkov <maxim.kuvyrkov@linaro.org> Cc: Milian Wolff <milian.wolff@kdab.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20180327060956.1c01ebe67a2a941bb4468c6f@arm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
