From 5e2f764234bd0ef9542902fb608e525c41e0d7ee Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 20 Dec 2016 15:10:50 +0000 Subject: [PATCH] irqchip/gic-v3-its: Add VPE invalidation hook When a guest issues a INVALL command targetting a collection, it must be translated into a VINVALL for the VPE that has this collection. This patch implements a hook that offers this functionallity to the hypervisor.
