2013-03-15perf evlist: Add thread_map__nr() helperNamhyung Kim1-0/+5
Introduce and use the thread_map__nr() function to protect a possible NULL pointer dereference and cleanup the code a bit.

2012-04-11perf tools: Fix thread map that is type pid_tRobert Richter1-1/+1
Thread map is actually type pid_t and not int. Signed-off-by: Robert Richter <[email protected]> Cc: Ingo Molnar <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2012-02-13perf tools: Allow multiple threads or processes in record, stat, topDavid Ahern1-0/+4
Allow a user to collect events for multiple threads or processes using a comma separated list. e.g., collect data on a VM and its vhost thread: perf top -p 21483,21485 perf stat -p 21483,21485 -ddd perf record -p 21483,21485 or monitoring vcpu threads perf top -t 21488,21489 perf stat -t 21488,21489 -ddd perf record -t 21488,21489 Cc: Frederic Weisbecker <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Thomas Gleixner <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: David Ahern <[email protected]> Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
2012-01-24perf tools: Introduce per user viewArnaldo Carvalho de Melo1-1/+2
The new --uid command line option will show only the tasks for a given user, using the proc interface to figure out the existing tasks. Kernel work is needed to close races at startup, but this should already be useful in many use cases.

2011-01-24perf threads: Move thread_map to separate fileArnaldo Carvalho de Melo1-0/+15
To untangle it from struct thread handling, that is tied to symbols, etc. Right now in the python bindings I'm working on I need just a subset of the util/ files, untangling it allows me to do that.
