Sample output below after applying patch to fix printing os->prefix. # ./perf stat -x, --per-socket -a -C 1 ls S0,1,82.11,msec,cpu-clock,82111626,100.00,1.000,CPUs utilized S0,1,2,,context-switches,82109314,100.00,24.358,/sec ------ ====> S0,1,,,,,,,1.71,stalled cycles per insn The above command line uses field separator as "," via "-x," option and per-socket option displays socket value as first field. But here the last line for "stalled cycles per insn" has more separators. Each csv output line is expected to have 8 field separators (for the 9 fields), where as last line has 9 "," in the result. Patch fixes this issue. The counter stats are displayed by function "perf_stat__print_shadow_stats" in code "util/stat-shadow.c". While printing the stats info for "stalled cycles per insn", function "new_line_csv" is used as new_line callback. The fields printed in each line contains: "Socket_id,aggr nr,Avg,unit,event_name,run,enable_percent,ratio,unit" The metric output prints Socket_id, aggr nr, ratio and unit. It has to skip through remaining five fields ie, Avg,unit,event_name,run,enable_percent. The csv line callback uses "os->nfields" to know the number of fields to skip to match with other lines. Currently it is set as: os.nfields = 3 + aggr_fields[config->aggr_mode] + (counter->cgrp ? 1 : 0); But in case of aggregation modes, csv_sep already gets printed along with each field (Function "aggr_printout" in util/stat-display.c). So aggr_fields can be removed from nfields. And fixed number of fields to skip has to be "4". This is to skip fields for: "avg, unit, event name, run, enable_percent" This needs 4 csv separators. Patch removes aggr_fields and uses 4 as fixed number of os->nfields to skip. After the patch: # ./perf stat -x, --per-socket -a -C 1 ls S0,1,79.08,msec,cpu-clock,79085956,100.00,1.000,CPUs utilized S0,1,7,,context-switches,79084176,100.00,88.514,/sec ------ ====> S0,1,,,,,,0.81,stalled cycles per insn Fixes: 92a61f6412d3a09d ("perf stat: Implement CSV metrics output") Reported-by: Disha Goel <disgoel@linux.vnet.ibm.com> Reviewed-by: Kajol Jain <kjain@linux.ibm.com> Signed-off-by: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Tested-by: Disha Goel <disgoel@linux.vnet.ibm.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ian Rogers <irogers@google.com> Cc: James Clark <james.clark@arm.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Madhavan Srinivasan <maddy@linux.vnet.ibm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Nageswara R Sastry <rnsastry@linux.ibm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: linuxppc-dev@lists.ozlabs.org Link: https://lore.kernel.org/r/20221205042852.83382-1-atrajeev@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> 2022-12-14perf record: Add remaining branch filters: "no_cycles", "no_flags" & "hw_index"Anshuman Khandual2-0/+8 This adds all remaining branch filters i.e "no_cycles", "no_flags" and "hw_index".

That is, the io_setup syscall (number 0) and all but one (typically ftruncate; 64) of the syscalls that are defined symbolically (like "#define __NR_ftruncate __NR3264_ftruncate") at the point where "sort" is applied. This creation-of-syscalls.c-scheme is, judging from comments, copy-pasted from powerpc, and worked there because at the time, its tools/arch/powerpc/include/uapi/asm/unistd.h had *literals*, like "#define __NR_ftruncate 93". With sort being numeric and the non-numeric key effectively evaluating to 0, the sort option "-u" means these "duplicates" are removed. There's no need to remove syscall lines with duplicate numbers for arm64 because there are none, so let's fix that by just losing the "-u". Having the table numerically sorted on syscall-number for the rest of the syscalls looks nice, so keep the "-n".

Depsite being defined in atomic.h, and despite the kernel versions being atomic in the kernel, tools' {clear,set}_bit() helpers aren't actually atomic. Move to the double-underscore versions so that the versions that are expected to be atomic (for kernel developers) can be made atomic without affecting users that don't want atomic operations.
