2021-08-24libperf tests: Fix verbose printingShunsuke Nakamura1-0/+2
libperf's verbose printing checks the -v option every time the macro _T_ START is called. Since there are currently four libperf tests registered, the macro _T_ START is called four times, but verbose printing after the second time is not output. Resets the index of the element processed by getopt() and fix verbose printing so that it prints in all tests.

2021-07-07libperf: Change tests to single static and shared binariesJiri Olsa1-2/+2
Make tests to be two binaries 'tests_static' and 'tests_shared', so the maintenance is easier. Adding tests under libperf build system, so we define all the flags just once. Adding make-tests tule to just compile tests without running them.

2021-04-15libperf tests: Add support for verbose printingRob Herring1-0/+32
Add __T_VERBOSE() so tests can add verbose output. The verbose output is enabled with the '-v' command line option. Running 'make tests V=1' will enable the '-v' option when running the tests. It'll be used in the next patch, for a user space counter access test.
