[Qemu-devel] [PATCH 0/3] apic: Fixes for userspace model


From: Jan Kiszka
Subject: [Qemu-devel] [PATCH 0/3] apic: Fixes for userspace model
Date: Mon, 9 Jul 2012 16:42:29 +0200

As Avi noted recently, there is a problem in way we inject interrupts
into the userspace APIC under KVM: The TRP check over the iothread may
race with the VCPU raising the TPR value while in KVM mode. Patch 3
addresses this issue.

The other two patches fix problems I came across while thinking about
the first one.

Who would like to process this series, up/master? Or should it go in
directly?

Jan Kiszka (3):
  apic: Resolve potential endless loop around apic_update_irq
  apic: Reevaluate pending interrupts on LVT_LINT0 changes
  apic: Defer interrupt updates to VCPU thread
