[Qemu-devel] [PATCH v3 0/9] uq/master: TPR access optimization for Windows guests

[Jan Kiszka <jan.kiszka@siemens.com>]

v3 comes with the following changes:
 - clear TPR access report on system reset
   (in case we load a guest without the option ROM)
 - addressed review comments on details in kvmvapic.c
 - streamlined 16-bit VAPIC port handling
 - included cleanup for useless next_cpu casts in cpus.c
   (to avoid conflicts on merge)

The series is also available at

    git://git.kiszka.org/qemu-kvm.git queues/kvm-tpr

Please review/apply.
