More generally, the target interrupt descriptors (sense values, in particular) in a device tree interrupt map describe the interrupts as seen on the target interrupt controller, *not* as seen on this (source) interrupt domain. This should be obvious, but since the source interrupt descriptor for PCI doesn't have a sense value (it's always level low, after all), it can be confusing. Well, interrupts always are confusing :-) Segher _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
