Hi All, > @Wim: Would you accept drivers which can only ping a watchdog but > neither start/stop it? Will look the driver in more detail later this week. To answer this question though: Userspace needs to be able to stop and start watchdog devices. That's why we have the solution with the timer. I will look up the example that I created in the past (as part of the documentation) and add it to linux-next (so that it is available as an example for everyone) and either sent it to Marc or sent Marc an updated version of his code so that he can test it. Bottom line: Yes, there is hardware available that can only be pinged and not be stopped, but No, Userspace needs the start/stop and ping functionality so that a watchdog daemon can work correctly (which is important because some watchdog daemons also do application testing. I prefer to add this driver first with the timer build into the driver. We should indeed think about putting the timer in the framework, but we need to think about how we can do this when we have multiple devices (where some need it and others don't). The roadmap should be first multiple devices and then the timer so that we don't create an extra hurdle for the future. Marc: I hope to sent you something still today.
