Re: [Xenomai-core] v2.1-rc4 RTDM bug

Returning XN_ISR_PROPAGATE passes the grabbed timer interrupt to Linux and top works again. As forwarding interrupts to the non-realtime domain is not a common use-case of realtime device drivers, I decided to drop the propagation support at RTDM level. So if you are including this mechanism in your demo, please mark this pattern as something RTDM drivers should normally NOT do (and explain what's reason for it here). Thanks Jan! I'll add that in a few. Best regards, Hannes. ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
