This will allow dynamically adding/removing at least virtio-net pci
devices which are quite the norm in cloud environment with QEMU/KVM
netdev_add bridge,id=wan2,br=br-wan,helper=/home/yousong/.usr/libexec/qemu-bridge-helper
device_add virtio-net-pci,id=devwan2,netdev=wan2,mac=11:22:33:22:11:00
The config was formed by selecting target x86/64 first, then select
CONFIG_HOTPLUG_PCI and CONFIG_HOTPLUG_PCI_ACPI with
make kernel_menuconfig CONFIG_TARGET=subtarget
The following text tries to explain how the current config was formed
1. CONFIG_PCI_LABEL and CONFIG_ATA_PIIX were removed because they were
already enabled in x86 platform config
2. CONFIG_ATA_SFF was removed because it was enabled in generic config
3. CONFIG_NLS was removed because it will be selected by CONFIG_PCI_LABEL

CPU frequency scaling enables the operating system to scale the CPU
frequency up or down in order to save power. CPU frequencies can be
scaled automatically depending on the system load, in response to ACPI
events, or manually by userspace programs.
