[Qemu-devel] [PATCH v11 0/5] remove icc bus/bridge

From: Zhu Guihua
Subject: [Qemu-devel] [PATCH v11 0/5] remove icc bus/bridge
Date: Wed, 2 Sep 2015 17:36:17 +0800

ICC Bus was used for providing a hotpluggable bus for APIC and CPU, but now we
use HotplugHandler to make hotplug. So ICC Bus is unnecessary.

This code has passed the new pc-cpu-test.
And I have tested with kvm along with kernel_irqchip=on/off, it works fine.

This patch series is based on the latest master and
'[PATCH v3] i386: keep cpu_model field in MachineState uptodate'
which has been reviewed but not been merged.

 -improve commit messages
 -split per CPU AS change into a separate patch

 -improve commit messages in patch 1 and 2
 -make the check of cpu->cpu_as_root simplier

 -use a callback to correct reset sequence for x86
 -update apic mmio mapping

Chen Fan (2):
  apic: move APIC's MMIO region mapping into APIC
  cpu/apic: drop icc bus/bridge

Zhu Guihua (3):
  apic: use per CPU AS to map APIC MMIO for TCG
  x86: use new method to correct reset sequence
  icc_bus: drop the unused files
