2012-10-02T21:36:44Z

Add internal --list-opts option to print all of long option names to stdout so that it can be used for bash completion engine.

perf options: add OPT_CALLBACK_DEFAULT_NOOPT

2010-12-06T17:33:29Z

Add new macro OPT_CALLBACK_DEFAULT_NOOPT for parse_options. It enables to pass the default value (opt->defval) to the callback function processing options require no argument.

perf options: Type check all the remaining OPT_ variants

2010-05-17T19:22:41Z

OPT_SET_INT was renamed to OPT_SET_UINT since the only use in these tools is to set something that has an enum type, that is builtin compatible with unsigned int. Several string constifications were done to make OPT_STRING require a const char * type.

perf options: Check v type in OPT_U?INTEGER

2010-05-17T18:43:38Z

To avoid problems like the one fixed by Stephane Eranian in 3de29ca, now we'll got this instead: bench/sched-messaging.c:259: error: negative width in bit-field ‘’ bench/sched-messaging.c:261: error: negative width in bit-field ‘’ Which is rather cryptic, but is how BUILD_BUG_ON_ZERO works, so kernel hackers should be already used to this. With it in place found some problems, fixed by changing the affected variables to sensible types or changed some OPT_INTEGER to OPT_UINTEGER. Next csets will go thru converting each of the remaining OPT_ so that review can be made easier by grouping changes per type per patch.

perf options: Introduce OPT_UINTEGER

2010-05-17T18:30:00Z

For unsigned int options to be parsed, next patches will make use of it. Cc: Frédéric Weisbecker Cc: Mike Galbraith Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Cc: Tom Zanussi LKML-Reference: Signed-off-by: Arnaldo Carvalho de Melo

perf options: Introduce OPT_U64

2010-05-17T15:16:48Z

We have things like user_interval (-c/--count) in 'perf record' that needs this. Cc: Frédéric Weisbecker Cc: Mike Galbraith Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Cc: Tom Zanussi LKML-Reference: Signed-off-by: Arnaldo Carvalho de Melo

perf: Fix endianness argument compatibility with OPT_BOOLEAN() and introduce OPT_INCR()

2010-04-14T09:26:44Z

Parsing an option from the command line with OPT_BOOLEAN on a bool data type would not work on a big-endian machine due to the manner in which the boolean was being cast into an int and incremented. For example, running 'perf probe --list' on a PowerPC machine would fail to properly set the list_events bool and would therefore print out the usage information and terminate. This patch makes OPT_BOOLEAN work as expected with a bool datatype. For cases where the original OPT_BOOLEAN was intentionally being used to increment an int each time it was passed in on the command line, this patch introduces OPT_INCR with the old behaviour of OPT_BOOLEAN (the verbose variable is currently the only such example of this). I have reviewed every use of OPT_BOOLEAN to verify that a true C99 bool was passed. Where integers were used, I verified that they were only being used for boolean logic and changed them to bools to ensure that they would not be mistakenly used as ints. The major exception was the verbose variable which now uses OPT_INCR instead of OPT_BOOLEAN. Signed-off-by: Ian Munsie Acked-by: David S.

perf: Allow perf utilities to have "callback" options without arguments

2009-09-19T09:42:11Z

timechart needs to add a "callback" type command line argument that does not take arguments. This patch adds the parse-options.h infrastructure to make this possible.
