Kernel Summit 2006: RealtimeKernel Summit 2006: RealtimePosted Jul 31, 2006 16:44 UTC (Mon) by Blaisorblade (guest, #25465)In reply to: Kernel Summit 2006: Realtime by obobo Parent article: Kernel Summit 2006: Realtime There is already a soft watchdog in the kernel almost exactly like that - the only difference from your proposal is that instead of one high-priority process it is the timer interrupt to do the check; I also think that since the time interrupt should remain a raw interrupt without a task checking for it (it's used for the scheduler) it is the same thing. And both things aren't safe when a process disables interrupts but that's not interesting (you really need a hardware watchdog for that).
