[igt-dev] [PATCH v3 02/12] scripts/code_cov_parse_info: add a tool to parse code coverage info files

From: Mauro Carvalho Chehab <mchehab at kernel.org>
The code coverage info files provide useful information about what
functions were called and how many times. It can also contain data that
it is not useful for the code coverage, like calls to non-DRM related
Kernel APIs.
Add a tool that helps filtering out non-DRM files and prints what
functions were called.
Both the stats, prints and output files are affected by the filters:
$ code_cov_parse_info --stat total.info
lines......: 40.8% (71989 of 176442 lines)
functions..: 50.2% (5975 of 11909 functions)
branches...: 28.7% (35006 of 121893 branches)
Source files: 744
$ code_cov_parse_info total.info --stat --only-drm
lines......: 40.3% (70244 of 174170 lines)
functions..: 50.8% (5835 of 11491 functions)
branches...: 28.4% (33096 of 116707 branches)
Ignored......: non-drm headers.
Source files.: 78.36% (583 of 744 total)
$ code_cov_parse_info total.info --stat --only-drm --ignore-unused -o o.info
lines......: 47.9% (70244 of 146752 lines)
functions..: 50.8% (5835 of 11491 functions)
branches...: 32.8% (33096 of 100900 branches)
Ignored......: non-drm headers and source files where none of its code ran.
Source files.: 58.87% (438 of 744 total), 75.13% (438 of 583 filtered)
$ code_cov_parse_info --stat o.info
lines......: 47.9% (70244 of 146752 lines)
functions..: 59.8% (5835 of 9763 functions)
branches...: 32.8% (33096 of 100900 branches)
Source files: 438

+=head1 NAME
+
+Parses lcov data from .info files.
+
+=head1 SYNOPSIS
+
+code_cov_parse_info <options> [input file(s)]
+
+At least one of the options B<--stat>, B<--print> and/or B<--output>
+should be used.
+
+=head1 OPTIONS
+
+=over 8
+
+=item B<--stat> or B<--statistics>
+
+Prints code coverage statistics.
+
+It displays function, line, branch and file coverage percentage.
+
+It also reports when one or more of the filtering parameters are used.
+
+The statistics report is affected by the applied filters.
+
+=item B<--print-coverage> or B<--print_coverage> or B<--print> or B<-p>
+
+Prints the functions that were executed in runtime and how many times
+they were reached.
+
+The function coverage report is affected by the applied filters.
+
+=item B<--print-unused> or B<-u>
+
+Prints the functions that were never reached.
+
+The function coverage report is affected by the applied filters.
+
+
+=item B<--show-lines> or B<--show_lines>
+
+When printing per-function code coverage data, always output the source
+file and the line number where the function is defined.
+
+=item B<--output> B<[output file]> or B<-o> B<[output file]>
+
+Produce an output file merging all input files.
+
+The generated output file is affected by the applied filters.
+
+=item B<--only-drm> or B<--only_drm>
+
+Filters out includes outside the DRM subsystem, plus trace files.
+E. g. it will exclude *.h files that match the following regular expressions:
+
+ - .*trace.*\.h$
+
+And *.h files that don't match:
+
+ - drm
+
+=item B<--only-i915> or B<--only_i915>
+
+Filters out C files and headers outside drm core and drm/i915.
+
+E. g. code coverage results will include only the files that that match
+the following regular expressions:
+
+ - drm/i915/
+ - drm/ttm
+ - drm/vgem
+
+Excluding files that match:
+
+ - selftest
+
+=item B<--func-filters> B<[filter's file]> or B<-f> B<[filter's file]>
+
+Take into account only the code coverage for the functions that match
+the regular expressions contained at the B<[filter's file]>.
+
+When this filter is used, B<--ignore-unused> will be automaticaly enabled,
+as the final goal is to report per-function usage, and not per-file.
+
+=item B<--source-filters> B<[filter's file]> or B<-S> B<[filter's file]>
+
+Takes into account only the code coverage for the source files that match
+the regular expressions contained at the B<[filter's file]>.
+
+=item B<--ignore-unused> or B<--ignore_unused>
+
+Filters out unused C files and headers from the code coverage results.
+
+Sometimes, it is desired to ignore files where none of the functions on it
+were tested.
+
+The rationale is that such files may contain platform-specific drivers
+and code that will never be used, so, placing them will just bloat the
+report and decrease the code coverage statistics.
+
+This option is automaticaly enabled when B<--func-filters> is used.
