2013-04-16target-i386: Split out CPU creation and features parsingIgor Mammedov
Move CPU creation and features parsing into a separate cpu_x86_create() function, so that board would be able to set board-specific CPU properties before CPU is realized. Keep cpu_x86_init() for compatibility with the code that uses cpu_init() and doesn't need to modify CPU properties.

2013-04-16target-i386: Split APIC creation from initialization in x86_cpu_realizefn()Igor Mammedov
When APIC is hotplugged during CPU hotplug, device_set_realized() calls device_reset() on it. And if QEMU runs in KVM mode, following call chain will fail: apic_reset_common() -> kvm_apic_vapic_base_update() -> kvm_vcpu_ioctl(cpu->kvm_fd,...) due to cpu->kvm_fd not being initialized yet. cpu->kvm_fd is initialized during qemu_init_vcpu() but x86_cpu_apic_init() can't be moved after it because kvm_init_vcpu() -> kvm_arch_reset_vcpu() relies on APIC to determine if CPU is BSP for setting initial env->mp_state. So split APIC device creation from its initialization and realize APIC after CPU is created, when it's safe to call APIC's reset method.

Many of these should be cleaned up with proper qdev-/QOM-ification.

2013-04-03target-i386: Check for host features before filter_features_for_kvm()Eduardo Habkost
commit 5ec01c2e96910e1588d1a0de8609b9dda7618c7f broke "-cpu ..,enforce", as it has moved kvm_check_features_against_host() after the filter_features_for_kvm() call. filter_features_for_kvm() removes all features not supported by the host, so this effectively made kvm_check_features_against_host() impossible to fail. This patch changes the call so we check for host feature support before filtering the feature bits.

2013-02-27Fix guest OS hang when 64bit PCI bar presentAlexey Korolev
This patch addresses the issue fully described here: http://lists.nongnu.org/archive/html/qemu-devel/2013-02/msg01804.html Linux kernels prior to 2.6.36 do not disable the PCI device during enumeration process. Since lower and higher parts of a 64bit BAR are programmed separately this leads to qemu receiving a request to occupy a completely wrong address region for a short period of time. We have found that the boot process screws up completely if kvm-apic range is overlapped even for a short period of time (it is fine for other regions though). This patch raises the priority of the kvm-apic memory region, so it is never pushed out by PCI devices. The patch is quite safe as it does not touch memory manager.
