Introduce new infrastructure code for config management features of perf-config subcommand. This pathset contains basic code for various purposes of configuration management showing current configs, in the near future, showing all configs with default value, getting current configs from the config files or writing configs that user type on the config files, etc. IMHO, I think this infrastructure code is needed to add new funcationalities for config management of perf-config. If anyone reviews this, I'd appreciate it. Thanks, Taeung v9: - don't use the arbitrary maximum 'MAX_CONFIGS' (Arnaldo, Namhyung) - change two-dimensinal arrays 'default_config_items' to array of pointers (Namhyung) - remove needless 'enum perf_config_secion_idx' - add sections 'intel-pt','convert' and their items - modify perf_config_set__init() in accordance with new default config sections and items - (applied two previous patches 860b8d4 and 20105ca from this patchset) v8: - rebased onto the current acme/perf/core v7: - rename 'is_custom' to 'is_allocated' to be proper (Masami) - fix the code about free() or zfree() in perf_config_*__delete() (Masami) - check set == NULL or not in show_config() (Masami) v6: - don't use goto in add_config_item() (Masami) v5: - departmentalize perf_config_set__delete() (Arnaldo) - remove confusing find_config() (Arnaldo) - use pr_debug() instead of pr_err() (Arnaldo) - use zfree() instead of free() (Arnaldo) - more compact in perf_config_set__new() (Arnaldo) - rename variables 'perf_configs', 'config_items', etc. (Arnaldo) v4: - fill perf_config_set__delete() in collect_config() for state of error - fill the code setting is_custom value in add_config_item() (Namhyung) v3: - use the section list that contains configs each section instead of the single config list (Namhyung) - exclude a patch for '--list-all' option from this patchset v2: - remove perf_config_kind (user, system or both config files) and needless at this time, etc. (Namhyung) - separate this patch as several patches (Namhyung) - fix typing errors, etc. Taeung Song (2): perf config: Prepare all default configs perf config: Initialize perf_config_set with all default configs tools/perf/builtin-config.c | 11 ++- tools/perf/util/config.c | 187 ++++++++++++++++++++++++++++++++++++++++++-- tools/perf/util/config.h | 51 +++++++++++- 3 files changed, 238 insertions(+), 11 deletions(-) -- 2.5.0
