perf test: Move parse event automated tests to separated object

2012-05-22T14:19:16+00:00

Moving event parsing specific tests into separated file: util/parse-events-test.c Also changing the code a bit to ease running separate tests.

Merge remote-tracking branch 'tip/perf/urgent' into perf/core

2012-05-18T16:13:33+00:00

Merge reason: We are going to queue up a dependent patch: "perf tools: Move parse event automated tests to separated object" That depends on: commit e7c72d8 perf tools: Add 'G' and 'H' modifiers to event parsing Conflicts: tools/perf/builtin-stat.c Conflicted with the recent 'perf_target' patches when checking the result of perf_evsel open routines to see if a retry is needed to cope with older kernels where the exclude guest/host perf_event_attr bits were not used.

perf target: Add uses_mmap field

2012-05-17T15:32:54+00:00

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 evlist: Make create_maps() take struct perf_target

2012-05-02T18:23:11+00:00

Now we have all information that needed to create cpu/thread maps in struct perf_target, it'd be better using it as an argument.

perf tools: Introduce struct perf_target

2012-05-02T18:17:58+00:00

The perf_target struct will be used for taking care of cpu/thread maps based on user's input. Since it is used on various subcommands it'd better factoring it out. Thanks to Arnaldo for suggesting the better name.

perf test: Make the rdpmc test honour 'verbose' mode

2012-05-02T18:14:12+00:00

It was unconditionally printing debug stuff when in non -v mode we should just print the name and result of the test. Now: [root@sandy ~]# perf test rdpmc 6: x86 rdpmc test: Ok [root@sandy ~]# perf test -v rdpmc 6: x86 rdpmc test: --- start --- 0: 6030 1: 60030 2: 600050 3: 6000056 4: 60000070 5: 600000266 ---- end ---- x86 rdpmc test: Ok [root@sandy ~]# Cc: David Ahern Cc: Frederic Weisbecker Cc: Mike Galbraith Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-0tjedaozsy9oarq30nvzg74b@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add 'G' and 'H' modifiers to event parsing

They were dropped during conversion of event parser. Add test case to make sure this will not happen again.

perf tools: Fix modifier to be applied on correct events

2012-03-22T18:11:38+00:00

The event modifier needs to be applied only on the event definition it is attached to. The current state is that in case of multiple events definition (in single '-e' option, separated by ',') all will get modifier of the last one. Fixing this by adding separated list for each event definition, so the modifier is applied only to proper event(s). Added automated test to catch this, plus some other modifier tests.

perf tools: Add support to specify pmu style event

2012-03-16T17:30:13+00:00

Added new event rule to the event definition grammar: event_def: event_pmu | ... event_pmu: PE_NAME '/' event_config '/' Using this rule, event could be now specified like: cpu/config=1,config1=2,config2=3/u where pmu name 'cpu' is looked up via following path: ${sysfs_mount}/bus/event_source/devices/${pmu} and config options are bound to the pmu's format definiton: ${sysfs_mount}/bus/event_source/devices/${pmu}/format The hardcoded config options still stays and have precedence over any format field defined with same name.

perf tools: Add perf pmu object to access pmu format definition

2012-03-16T17:29:35+00:00

Adding pmu object which provides interface to pmu's sysfs event format definition located at: ${sysfs_mount}/bus/event_source/devices/${pmu}/format Following interface is exported: struct perf_pmu* perf_pmu__find(char *name); - this function returns pmu object, which is then passed as a handle to other interface functions int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr, struct list_head *head_terms); - this function configures perf_event_attr struct based on pmu's format definitions and config terms data, containined in head_terms list. Parser generator is used to retrive the pmu's format definition. The generated parser is part of the patch. Added makefile rule 'pmu-parser' to generate the parser code out of the bison/flex sources. Added builtin test 'Test perf pmu format parsing', which could be run like: perf test pmu Acked-by: Peter Zijlstra Signed-off-by: Jiri Olsa Link: http://lkml.kernel.org/n/tip-errz96u1668gj9wlop1zhpht@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo
