| |
Since the commit 943b69ac1884 ("perf parse-events: Set exclude_guest=1 for user-space counting"), 'exclude_guest=1' is set for user-space counting; and the branch sample's modifier has been altered, the sample event name has been changed from "branches:u:" to "branches:uH:", which gives out info for "user-space and host counting".
But the cs-etm testing's regular expression cannot match the updated branch sample event and leads to test failure.
This patch updates the branch sample parttern by using a more flexible expression '.*' to match branch sample's modifiers, so that allows the testing to work as expected.
