perf test: Rename struct test to test_suite

2021-11-13T13:32:22+00:00

This is to align with kunit's terminology.

perf test: Move each test suite struct to its test

2021-11-13T13:30:58+00:00

Rather than export test functions, export the test struct. Rename with a suite__ prefix to avoid name collisions. Committer notes: Its '&suite__vectors_page', not '&suite__vectors_pages', noticed when cross building to arm (32-bit).

perf evlist: Rename struct perf_evlist to struct evlist

2019-07-29T21:34:42+00:00

Rename struct perf_evlist to struct evlist, so we don't have a name clash when we add struct perf_evlist in libperf.

perf time-utils: Add support for multiple explicit time intervals

2019-06-10T19:20:13+00:00

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.

perf tests: Add a test for time-utils
