Subject: [PATCH 0/4] Fix book3s-pr KVM with preemption
Date: Fri, 9 Dec 2011 16:26:48 +0100 [thread overview]
Message-ID: <1323444412-18482-1-git-send-email-agraf@suse.de> (raw)
So far we got away with not implementing preemption properly. However,
recently users emerged who wanted to run PREEMPT_xxx kernels, running
into issues with KVM on there.
This patch set fixes all preempt issues I've found so far with Book3S
PR KVM.
Alexander Graf (4):
KVM: PPC: Book3s: PR: Disable preemption in vcpu_run
KVM: PPC: Book3s: PR: No irq_disable in vcpu_run
KVM: PPC: Use get/set for to_svcpu to help preemption
KVM: PPC: align vcpu_kick with x86
