perf script: Fix ip display when type != attr->type
set_print_ip_opts() was not being called when type != attr->type because there is not a one-to-one relationship between output types and attr->type. That resulted in ip not printing. The attr_type() function is removed, and the match of attr->type to output type is corrected. Example on ADL using taskset to select an atom cpu: # perf record -e cpu_atom/cpu-cycles/ taskset 0x1000 uname Linux [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.003 MB perf.data (7 samples) ] Before: # perf script | head taskset 428 [-01] 10394.179041: 1 cpu_atom/cpu-cycles/: taskset 428 [-01] 10394.179043: 1 cpu_atom/cpu-cycles/: taskset 428 [-01] 10394.179044: 11 cpu_atom/cpu-cycles/: taskset 428 [-01] 10394.179045: 407 cpu_atom/cpu-cycles/: taskset 428 [-01] 10394.179046: 16789 cpu_atom/cpu-cycles/: taskset 428 [-01] 10394.179052: 676300 cpu_atom/cpu-cycles/: uname 428 [-01] 10394.179278: 4079859 cpu_atom/cpu-cycles/: After: # perf script | head taskset 428 10394.179041: 1 cpu_atom/cpu-cycles/: ffffffff95a0bb97 __intel_pmu_enable_all.constprop.48+0x47 ([kernel.kallsyms]) taskset 428 10394.179043: 1 cpu_atom/cpu-cycles/: ffffffff95a0bb97 __intel_pmu_enable_all.constprop.48+0x47 ([kernel.kallsyms]) taskset 428 10394.179044: 11 cpu_atom/cpu-cycles/: ffffffff95a0bb97 __intel_pmu_enable_all.constprop.48+0x47 ([kernel.kallsyms]) taskset 428 10394.179045: 407 cpu_atom/cpu-cycles/: ffffffff95a0bb97 __intel_pmu_enable_all.constprop.48+0x47 ([kernel.kallsyms]) taskset 428 10394.179046: 16789 cpu_atom/cpu-cycles/: ffffffff95a0bb97 __intel_pmu_enable_all.constprop.48+0x47 ([kernel.kallsyms]) taskset 428 10394.179052: 676300 cpu_atom/cpu-cycles/: 7f829ef73800 cfree+0x0 (/lib/libc-2.32.so) uname 428 10394.179278: 4079859 cpu_atom/cpu-cycles/: ffffffff95bae912 vma_interval_tree_remove+0x1f2 ([kernel.kallsyms]) Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Reviewed-by: Kan Liang <kan.liang@linux.intel.com> Cc: Jin Yao <yao.jin@linux.intel.com> Cc: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20210911133053.15682-1-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
