2019-07-29	perf evlist: Rename struct perf_evlist to struct evlist	Jiri Olsa	1	-1/+1
	Rename struct perf_evlist to struct evlist, so we don't have a name clash when we add struct perf_evlist in libperf. Committer notes: Added fixes to build on arm64, from Jiri and from me (tools/perf/util/cs-etm.c) Signed-off-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Alexey Budankov <alexey.budankov@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Michael Petlan <mpetlan@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/20190721112506.12306-6-jolsa@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2019-06-10	perf time-utils: Add support for multiple explicit time intervals	Adrian Hunter	1	-0/+17
	Currently only a single explicit time range is accepted. Add support for multiple ranges separated by spaces, which requires the string to be quoted. Update the time utils test accordingly.
