...ted last year. After Avi''s suggestions to look at PLE handler''s improvements, various optimizations in PLE handling have been tried. With this series we see that we could get little more improvements on top of that. Changes before V8: Ticketlock change history: Changes in V7: - Reabsed patches to 3.4-rc3 - Added jumplabel split patch (originally from Andrew Jones rebased to 3.4-rc3 - jumplabel changes from Ingo and Jason taken and now using static_key_* instead of static_branch. - using UNINLINE_SPIN_UNLOCK (which was splitted as per suggestion from Linus) - This patc...

...ting paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. The series provides implementation for both Xen and KVM.(targeted for 3.5 window) Note: This needs debugfs changes patch that should be in Xen / linux-next https://lkml.org/lkml/2012/3/30/687 Changes in V8: - Reabsed patches to 3.4-rc4 - Combined the KVM changes with ticketlock + Xen changes (Ingo) - Removed CAP_PV_UNHALT since it is redundant (Avi). But note that we need newer qemu which uses KVM_GET_SUPPORTED_CPUID ioctl. - Rewrite GET_MP_STATE condition (Avi) - Make pv_unhalt = bool (Avi) - Move out...

...inux guest running on KVM-hypervisor to support pv-ticket spinlocks, based on Xen's implementation. One hypercall is introduced in KVM hypervisor,that allows a vcpu to kick another vcpu out of halt state. The blocking of vcpu is done using halt() in (lock_spinning) slowpath. Changes in V4: - reabsed to 3.2.0 pre. - use APIC ID for kicking the vcpu and use kvm_apic_match_dest for matching. (Avi) - fold vcpu->kicked flag into vcpu->requests (KVM_REQ_PVLOCK_KICK) and related changes for UNHALT path to make pv ticket spinlock migration friendly. (Avi, Marcello) - Added Documentation for C...
