From 389a00d3ad02a06b5d6d692cce76fed6a3dae8b4 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Tue, 9 Feb 2016 15:24:57 +0000 Subject: irqchip/gic: Only set the EOImodeNS bit for the root controller EOImode1 is only used for the root controller and hence only the root controller uses the eoimode1 functions for handling interrupts. However, if the root controller supports EOImode1, then the EOImodeNS bit will be set for all GICs, enabling EOImode1. This is not what we want and this causes interrupts on non-root GICs to only be dropped in priority but never deactivated. Therefore, only set the EOImodeNS bit for the root controller.
