Re: OpenPIC / CPM2 PIC and cascading interrupt priorities

and their combinations (in the general case for Linux, not just for OpenPIC and CPM2), I'm starting to think that it would be quite complicated and error prone, so i guess i'll happily use a tasklet :) Thanks! Guillaume Knispel ___ Linuxppc-dev mailing

OpenPIC / CPM2 PIC and cascading interrupt priorities

anybody think it could be interesting to reorganize the Linux irq layers such as the priorities of cascaded interrupts are respected (that would need some changes in the architecture independent code), or is this a stupid idea and I should just use a tasklet? Cheers, Guillaume KNISPEL
