Subject: irqchip/gic-v3-its: Add VPE invalidation hook
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5e2f764234bd0ef9542902fb608e525c41e0d7ee;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

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.
