It has to determine whether a given IRQ is cascaded and therefore must be specially serviced WRT acknowledging. The required acknowledging of IRQ-subchannels is done in __ipipe_mach_demux_irq together with the call of __ipipe_handle_irq() after having determined the correct IRQ number where necessary. -- Sebastian _______________________________________________ Adeos-main mailing list [email protected] https://mail.gna.org/listinfo/adeos-main
