perf record: Add clockid parameter

2015-04-08T13:04:55Z

Teach perf-record about the new perf_event_attr::{use_clockid, clockid} fields. Add a simple parameter to set the clock (if any) to be used for the events to be recorded into the data file. Since we store the entire perf_event_attr in the EVENT_DESC section we also already store the used clockid in the data file. Signed-off-by: Peter Zijlstra (Intel) Acked-by: David Ahern Cc: "H.

perf: Bump max number of cpus to 1024

2015-03-26T13:52:28Z

SPARC based systems currently support up to 1024 cpus (e.g. T5-8). Allow perf to work on those systems. Signed-off-by: David Ahern Link: http://lkml.kernel.org/r/1427213438-127216-1-git-send-email-david.ahern@oracle.com Signed-off-by: Arnaldo Carvalho de Melo

perf record: Support recording running/enabled time

2015-02-25T15:42:23Z

Add an option to perf record to record running/enabled time for read events, similar to what stat does. This is useful to understand multiplexing problems. Right now the report support is not great, but at least report -D already supports it.

perf tools: Export usage string and option table of perf record

2014-10-29T12:32:47Z

Those are shared with other builtin commands like kvm, script. So make it accessable from them. This is a preparation of later change that limiting possible options.

perf tools: Move callchain config from record_opts to callchain_param

2014-09-26T15:40:33Z

So that all callchain config parameters can be read/written to a single place. It's a preparation to consolidate handling of all callchain options.

perf tools: Move syscall and arch specific defines from perf.h

2014-05-05T15:48:28Z

Into new perf-sys.h header. The main reason is to separate system specific perf data from perf tool stuff, so it could be used in small test programs, as requested Peter: http://lkml.kernel.org/r/20140502115201.GI30445@twins.programming.kicks-ass.net This separation makes the perf.h header more clear.
