So far, it is difficult that the state of perf configs is looked through
and there's no knowing what kind of other variables except variables in
perfconfig.example.
Also perf configs can't be changed without manually modifying $HOME/.perfconfig
or
$(sysconfdir)/perfconfig file. So I suggest this patchset of the perf-config
command
which can list, get, set, remove perf configs or list with default config
values as below.
[PATCH v5 1/6] perf tools: Add 'perf-config' command
[PATCH v5 2/6] perf config: Add '--system' and '--user' options to
select which config file to be used
[PATCH v5 3/6] perf config: Add a option 'list-all' to perf-config
[PATCH v5 4/6] perf config: Add 'get' functionality
[PATCH v5 5/6] perf config: Add 'set' feature
[PATCH v5 6/6] perf config: Add a option 'remove' to perf-config
Changes in v5:
- Simplify the switch statement in cmd_config()
- Set a config file path with '--system' or '--user'
instead of '--global' or '--system' as suggested by Namhyung. (PATCH v5
2/6)
- The patch about 'get' and 'set 'split into two patchs
as suggested by Namhyung. (PATCH v5 4/6, PATCH v5 5/6)
Changes in v4:
- If some config value is default value, notice it is '(default)'
as suggested by Jirka. (PATCH v4 3/5)
- If there wasn't any perfconfig file, perf-config malfunctioned like
Jirka pointed out. So add exception routine with '--global' and
'--system'
option which can select perf config file path. (PATCH v4 2/5)
Changes in v3:
- Add a config variable 'kmem.default' with a default value as
suggested by Namhyung.
(PATCH v3 2/5, PATCH v4 3/5)
Changes in v2:
- Change option name of listing all configs as '--list-all' instead of
'--all'
as suggested by Namhyung. (PATCH v2 3/4, PATCH v4 4/5)
- Correct small infelicities or typing errors in a perf-config
documention
as suggested by Arnaldo. (PATCH v2 1/4, PATCH v4 1/5)
- Declaration a global variable 'static struct default_configsets' has
config variables
with default values instead of using a 'util/PERFCONFIG-DEFAULT' file.
(PATCH v2 3/4, PATCH v4 3/5)
- Add a function to normalize a value and check data type of it.
(PATCH v2 2/4, PATCH v4 3/5)
- Simplify parsing arguments as arguments is just divided by '=' and
then
in front of '.' is a section, between '.' and '=' is a name, and behind
'=' is a value.
(PATCH v2 2/4, PATCH v4 3/5)
- If run perf-config command without any option, perf-config work as
'--list'.
(PATCH v2 1/4, PATCH v4 1/5)
