*	perf/tool: Add PMU event alias support	Zheng Yan	2012-06-18	1	-1/+10
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add support to specify alias term within the event description. The definition of pmu event alias is located at: ${sysfs_mount}/bus/event_source/devices/${pmu}/events/ Each file in the 'events' directory defines a event alias. Its contents are like: config=1,config1=2 Using pmu event alias, an event can be now specified like: uncore/CLOCKTICKS/ or uncore/event=CLOCKTICKS/ Signed-off-by: Zheng Yan <zheng.z.yan@intel.com> [ Cleaned it up. ] Signed-off-by: Jiri Olsa <jolsa@redhat.com> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/1339741902-8449-13-git-send-email-zheng.z.yan@intel.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
*	perf tools: Add perf pmu object to access pmu format definition	Jiri Olsa	2012-03-16	1	-0/+41
	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 <peterz@infradead.org> Signed-off-by: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/n/tip-errz96u1668gj9wlop1zhpht@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
