From cd82a32e9924d3a82bd27f830755d23e4ded25bc Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Thu, 15 Mar 2012 20:09:17 +0100 Subject: perf tools: Add perf pmu object to access pmu format definition 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 --- tools/perf/Makefile | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'tools/perf/Makefile') diff --git a/tools/perf/Makefile b/tools/perf/Makefile index dfc80289d7ff..e07fbd838749 100644 --- a/tools/perf/Makefile +++ b/tools/perf/Makefile @@ -276,6 +276,7 @@ LIB_H += util/build-id.h LIB_H += util/debug.h LIB_H += util/debugfs.h LIB_H += util/sysfs.h +LIB_H += util/pmu.h LIB_H += util/event.h LIB_H += util/evsel.h LIB_H += util/evlist.h @@ -323,6 +324,7 @@ LIB_OBJS += $(OUTPUT)util/config.o LIB_OBJS += $(OUTPUT)util/ctype.o LIB_OBJS += $(OUTPUT)util/debugfs.o LIB_OBJS += $(OUTPUT)util/sysfs.o +LIB_OBJS += $(OUTPUT)util/pmu.o LIB_OBJS += $(OUTPUT)util/environment.o LIB_OBJS += $(OUTPUT)util/event.o LIB_OBJS += $(OUTPUT)util/evlist.o @@ -361,6 +363,8 @@ LIB_OBJS += $(OUTPUT)util/thread_map.o LIB_OBJS += $(OUTPUT)util/trace-event-parse.o LIB_OBJS += $(OUTPUT)util/parse-events-flex.o LIB_OBJS += $(OUTPUT)util/parse-events-bison.o +LIB_OBJS += $(OUTPUT)util/pmu-flex.o +LIB_OBJS += $(OUTPUT)util/pmu-bison.o LIB_OBJS += $(OUTPUT)util/trace-event-read.o LIB_OBJS += $(OUTPUT)util/trace-event-info.o LIB_OBJS += $(OUTPUT)util/trace-event-scripting.o @@ -773,6 +777,9 @@ $(OUTPUT)util/rbtree.o: ../../lib/rbtree.c $(OUTPUT)PERF-CFLAGS $(OUTPUT)util/parse-events-flex.o: util/parse-events-flex.c $(OUTPUT)PERF-CFLAGS $(QUIET_CC)$(CC) -o $@ -c $(ALL_CFLAGS) -Wno-redundant-decls -Wno-switch-default -Wno-unused-function $< +$(OUTPUT)util/pmu-flex.o: util/pmu-flex.c $(OUTPUT)PERF-CFLAGS + $(QUIET_CC)$(CC) -o $@ -c $(ALL_CFLAGS) -Wno-redundant-decls -Wno-switch-default -Wno-unused-function $< + $(OUTPUT)util/scripting-engines/trace-event-perl.o: util/scripting-engines/trace-event-perl.c $(OUTPUT)PERF-CFLAGS $(QUIET_CC)$(CC) -o $@ -c $(ALL_CFLAGS) $(PERL_EMBED_CCOPTS) -Wno-redundant-decls -Wno-strict-prototypes -Wno-unused-parameter -Wno-shadow $< @@ -810,6 +817,7 @@ help: @echo ' info - make GNU info documentation (access with info )' @echo ' pdf - make pdf documentation' @echo ' event-parser - make event parser code' + @echo ' pmu-parser - make pmu format parser code' @echo ' TAGS - use etags to make tag information for source browsing' @echo ' tags - use ctags to make tag information for source browsing' @echo ' cscope - use cscope to make interactive browsing database' @@ -863,6 +871,10 @@ event-parser: $(QUIET_BISON)$(BISON) -v util/parse-events.y -d -o util/parse-events-bison.c $(QUIET_FLEX)$(FLEX) --header-file=util/parse-events-flex.h -t util/parse-events.l > util/parse-events-flex.c +pmu-parser: + $(QUIET_BISON)$(BISON) -v util/pmu.y -d -o util/pmu-bison.c + $(QUIET_FLEX)$(FLEX) --header-file=util/pmu-flex.h -t util/pmu.l > util/pmu-flex.c + ### Detect prefix changes TRACK_CFLAGS = $(subst ','\'',$(ALL_CFLAGS)):\ $(bindir_SQ):$(perfexecdir_SQ):$(template_dir_SQ):$(prefix_SQ) -- cgit v1.2.2
