We don't have a 'perf test' entry available to test the watchpoint functionality. Add a simple set of tests: - Read only watchpoint - Write only watchpoint - Read / Write watchpoint - Runtime watchpoint modification Ex.: on powerpc: $ sudo perf test 22 22: Watchpoint : 22.1: Read Only Watchpoint : Ok 22.2: Write Only Watchpoint : Ok 22.3: Read / Write Watchpoint : Ok 22.4: Modify Watchpoint : Ok Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.ibm.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Hendrik Brueckner <brueckner@linux.ibm.com> Cc: Kate Stewart <kstewart@linuxfoundation.org> Cc: Kim Phillips <kim.phillips@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Naveen N.
