Subject: [PATCH 0/3] QEMU kvm: Adding KICK_VCPU capability to i386 kvm
Date: Sun, 04 Dec 2011 23:55:42 +0530	[thread overview]
Message-ID: <20111204182541.28487.68163.sendpatchset@oc5400248562.ibm.com> (raw)

From: Raghavendra K T <raghavendra.kt@linux.vnet.ibm.com>

Three patch series following this, extends KVM-hypervisor
and Linux guest running on KVM-hypervisor to support pv-ticket spinlocks.

PV ticket spinlock helps to solve Lock Holder Preemption problem discussed in
http://www.amd64.org/fileadmin/user_upload/pub/LHP-commented_slides.pdf.

When spinlock is contended,a guest vcpu relinqueshes cpu by halt().
Correspondingly, One hypercall is introduced in KVM hypervisor,that allows
a vcpu to kick the halted vcpu to continue with execution.

The series will : 
- Update qemu with latest linux header files (to 3.2.0-rc1).
- Enable KICK_VCPU capability in kvm/i386.

Raghavendra K T(3):
  Sync the linux headers to 3.2.0-rc1
  Sync the linux headers to patched linux kernel with 
	KICK_VCPU capability.
  Add KICK_VCPU support in i386 target

---
The corresponding kernel patch is available in the thread
https://lkml.org/lkml/2011/11/30/62
