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 <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>
