[Qemu-devel] [PATCH qom-next v3 0/12] target-i386: re-factor CPU creatio

From: Igor Mammedov
Subject: [Qemu-devel] [PATCH qom-next v3 0/12] target-i386: re-factor CPU creation/initialization to QOM
Date: Wed, 30 May 2012 00:10:13 +0200

Moving code related to CPU creation and initialization internal parts
from board level into apic and cpu objects will allow X86CPU to better
model QOM object life-cycle.
It will allow to create X86CPU as any other object by creating it with
object_new() then setting properties and then calling x86_cpu_realize()
to make it running. Later x86_cpu_realize() should become realize property.

git tree for testing: 

Compile & Run tested:
  target-i386: tcg and kvm mode
  i386-linux-user: running of /bin/ls and /usr/bin/make on qemu tree

  store prev_debug_excp_handler globaly and not per target
  target-xtensa: use global prev_debug_excp_handler instead of local one
  target-i386: use global prev_debug_excp_handler instead of local one
  target-i386: move tcg initialization into x86_cpu_initfn()

  pc: Add CPU as /machine/cpu[n]
  apic: Replace cpu_env pointer by X86CPU link
     taken from Andreas' QOM CPUState part 4 series, to avoid conflict
     with reintroducing set_ptr replaced by link<X86CPU> in this patches

  target-i386: move cpu halted decision into x86_cpu_reset
  target-i386: introduce cpu-model property for x86_cpu
  target-i386: make cpu a child of /machine right after it's created
  pc: Enable MSI support at APIC level
     included here to prevent confilict since qom-next doesn't have it
     but next patch is depending on it.
  target-i386: initialize APIC at CPU level
  target-i386: move reset callback to cpu.c and call cpu_reset() in
