From 3217f7c25bca66eed9b07f0b8bfd1937169b0736 Mon Sep 17 00:00:00 2001 From: Christoffer Dall Date: Thu, 27 Aug 2015 16:41:15 +0200 Subject: KVM: Add kvm_arch_vcpu_{un}blocking callbacks Some times it is useful for architecture implementations of KVM to know when the VCPU thread is about to block or when it comes back from blocking (arm/arm64 needs to know this to properly implement timers, for example). Therefore provide a generic architecture callback function in line with what we do elsewhere for KVM generic-arch interactions.
