Commit f4a2aade ("perf tests powerpc: Fix branch stack sampling test to include sanity check for branch filter") added a skip if certain branch options aren't available. But the change added both -b (--branch-any) and --branch-filter options at the same time, which will always result in a failure on any platform because the arguments can't be used together. Fix this by removing -b (--branch-any) and leaving --branch-filter which already specifies 'any'. Also add warning messages to the test and perf tool. Output on x86 before this fix: $ sudo ./perf test branch 108: Check branch stack sampling : Skip After: $ sudo ./perf test branch 108: Check branch stack sampling : Ok Fixes: f4a2aade ("perf tests powerpc: Fix branch stack sampling test to include sanity check for branch filter") Signed-off-by: James Clark <james.clark@arm.com> Tested-by: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Anshuman.Khandual@arm.com Cc: Ingo Molnar <mingo@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kajol Jain <kjain@linux.ibm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20221028121913.745307-1-james.clark@arm.comSigned-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
