[Qemu-devel] [PATCH v4 4/4] hw/intc/arm_gicv3_its: Implement full reset

2017-11-24 Thread Eric Auger
Voiding the ITS caches is not supposed to happen via individual register writes. So we introduced a dedicated ITS KVM device ioctl to perform a cold reset of the ITS: KVM_DEV_ARM_VGIC_GRP_CTRL/KVM_DEV_ARM_ITS_CTRL_RESET. Let's use this latter if the kernel supports it. Signed-off-by: Eric Auger -
