2018-12-18perf trace: Allow asking for not suppressing common string prefixesArnaldo Carvalho de Melo
So far we've been suppressing common stuff such as "MAP_" in the mmap flags, showing "SHARED" instead of "MAP_SHARED", allow for those prefixes (and a few suffixes) to be shown: # trace -e *map,open*,*seek sleep 1 openat("/etc/ld.so.cache", CLOEXEC) = 3 mmap(0, 109093, READ, PRIVATE, 3, 0) = 0x7ff61c695000 openat("/lib64/libc.so.6", CLOEXEC) = 3 lseek(3, 792, SET) = 792 mmap(0, 8192, READ|WRITE, PRIVATE|ANONYMOUS) = 0x7ff61c693000 lseek(3, 792, SET) = 792 lseek(3, 864, SET) = 864 mmap(0, 1857568, READ, PRIVATE|DENYWRITE, 3, 0) = 0x7ff61c4cd000 mmap(0x7ff61c4ef000, 1363968, EXEC|READ, PRIVATE|FIXED|DENYWRITE, 3, 139264) = 0x7ff61c4ef000 mmap(0x7ff61c63c000, 311296, READ, PRIVATE|FIXED|DENYWRITE, 3, 1503232) = 0x7ff61c63c000 mmap(0x7ff61c689000, 24576, READ|WRITE, PRIVATE|FIXED|DENYWRITE, 3, 1814528) = 0x7ff61c689000 mmap(0x7ff61c68f000, 14368, READ|WRITE, PRIVATE|FIXED|ANONYMOUS) = 0x7ff61c68f000 munmap(0x7ff61c695000, 109093) = 0 openat("/usr/lib/locale/locale-archive", CLOEXEC) = 3 mmap(0, 217749968, READ, PRIVATE, 3, 0) = 0x7ff60f523000 # # vim ~/.perfconfig # # perf config llvm.dump-obj=true trace.add_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o trace.show_zeros=yes trace.show_duration=no trace.no_inherit=yes trace.show_timestamp=no trace.show_arg_names=no trace.args_alignment=0 trace.string_quote=" trace.show_prefix=yes # # # trace -e *map,open*,*seek sleep 1 openat(AT_FDCWD, "/etc/ld.so.cache", O_CLOEXEC) = 3 mmap(0, 109093, PROT_READ, MAP_PRIVATE, 3, 0) = 0x7f7ebbe59000 openat(AT_FDCWD, "/lib64/libc.so.6", O_CLOEXEC) = 3 lseek(3, 792, SEEK_SET) = 792 mmap(0, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS) = 0x7f7ebbe57000 lseek(3, 792, SEEK_SET) = 792 lseek(3, 864, SEEK_SET) = 864 mmap(0, 1857568, PROT_READ, MAP_PRIVATE|MAP_DENYWRITE, 3, 0) = 0x7f7ebbc91000 mmap(0x7f7ebbcb3000, 1363968, PROT_EXEC|PROT_READ, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 139264) = 0x7f7ebbcb3000 mmap(0x7f7ebbe00000, 311296, PROT_READ, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 1503232) = 0x7f7ebbe00000 mmap(0x7f7ebbe4d000, 24576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 3, 1814528) = 0x7f7ebbe4d000 mmap(0x7f7ebbe53000, 14368, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS) = 0x7f7ebbe53000 munmap(0x7f7ebbe59000, 109093) = 0 openat(AT_FDCWD, "/usr/lib/locale/locale-archive", O_CLOEXEC) = 3 mmap(0, 217749968, PROT_READ, MAP_PRIVATE, 3, 0) = 0x7f7eaece7000 # Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Luis Cláudio Gonçalves <lclaudio@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: https://lkml.kernel.org/n/tip-mtn1i4rjowjl72trtnbmvjd4@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

The intention is to have this as a library, since it is not perf specific at all.
