Subject: cec-ctl: add wakeup-sleep suboption Author: Hans Verkuil <[email protected]> Date: Fri Jul 31 15:30:48 2026 +0200 The cec-ctl --stress-test-random-standby-wakeup-cycle wait for 30 seconds after every 10 standby/wakeup cycles. But for some displays a longer wait time is needed. Add a new wakeup-sleep option that can be used to increase that time.
