Hello Thomas, Marc, Mans pointed me to a recent patch of yours. irqchip/gic: Use IRQD_FORWARDED_TO_VCPU flag Get rid of the handler_data abuse. I'm using a Cortex A9 based SoC. The platform's interrupt controller is cascaded into the GIC. I've been trying to get this to work for two weeks with no success. Details can be found here: http://thread.gmane.org/gmane.linux.ports.arm.kernel/440327 Do you think your patch my help with my situation?Not sure. A GICv1 shouldn't use EOImode==1 at all, so I don't quite see how you end-up there. Also, you seem to be using 4.2, and this code only landed during the 4.3 merge window.Sorry for being unclear. I'm having problems /without/ the patch, and Mans suggested I try the patch.But that patch will only apply if you run 4.3, because it fixes an issue in another patch that only exists in 4.3.
OK, forget I said anything then. I just saw someone mention it in connection with a BCM chip and thought it might be related without digging deeper. Nobody is paying me to do that. -- M?ns Rullg?rd mans at mansr.com
