From 3b92830ad41b2fe377e0765322e8aefd0ab8388d Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 25 Sep 2015 23:41:17 +0200 Subject: KVM: arm/arm64: implement kvm_arm_[halt,resume]_guest We introduce kvm_arm_halt_guest and resume functions. They will be used for IRQ forward state change. Halt is synchronous and prevents the guest from being re-entered. We use the same mechanism put in place for PSCI former pause, now renamed power_off. A new flag is introduced in arch vcpu state, pause, only meant to be used by those functions.
