perf target: Add uses_mmap field

2012-05-17T15:32:54Z

If perf doesn't mmap on event (like perf stat), it should not create per-task-per-cpu events. So just use a dummy cpu map to create a per-task event for this case.

perf target: Rename functions to avoid double negation

2012-05-16T15:09:34Z

Rename perf_target__no_{cpu,task} to perf_target__has_{cpu,task} because it's more intuitive and easy to parse (for human beings) when used with negation. The names are came out from David Ahern. It is intended to be a mechanical substitution without any functional change. The perf_target__none remains unchanged since I couldn't find a right name and it is hardly used with negation.

perf target: Consolidate target task/cpu checking

2012-05-07T20:52:05Z

There are places that check whether target task/cpu is given or not and some of them didn't check newly introduced uid or cpu list. Add and use three of helper functions to treat them properly.

perf tools: Introduce perf_target__strerror()

2012-05-07T20:30:21Z

The perf_target__strerror() sets @buf to a string that describes the (perf_target-specific) error condition that is passed via @errnum. This is similar to strerror_r() and does same thing if @errnum has a standard errno value.

perf target: Introduce perf_target__parse_uid()

2012-05-07T19:46:48Z

Add and use the modern perf_target__parse_uid() and get rid of the old parse_target_uid().

perf target: Introduce perf_target_errno

2012-05-07T19:46:35Z

The perf_target_errno enumerations are used to indicate specific error cases on perf target operations. It'd help libperf being a more generic library.

perf target: Split out perf_target handling code

2012-05-02T18:41:11Z

For further work on perf_target, it'd be better off splitting the code into a separate file.
