2014-10-15ide: add calling add_boot_device_patch in bootindex setter functionGonglei
On this way, we can assure the new bootindex take effect during vm rebooting. Meanwhile set the initial value of bootindex to -1. Because ide devcies's unit property maybe do not initialize when set_bootindex function is called, so that we don't know its suffix. So we have to save the call add_boot_device_path() on ide realize/init function. When we want to change bootindex during vm rebooting, we can call it in setter function.

2014-10-15usb-storage: add bootindex to qom propertyGonglei
Add a qom property with the same name 'bootindex', when we remove it form qdev property, things will continue to work just fine, and we can use qom features which are not supported by qdev property. Because usb-storage rely on scsi-disk which is created in usb_msg_realize_storage(), so we should store the SCSIDevice pointer in MSDState struct. Only in this way, we can change the global boot_order_list when we want to change the bootindex during vm rebooting by calling object_property_set_int(Object(SCSIDevice),).

2014-10-10s390x/kvm: propagate s390 cpu state to kvmDavid Hildenbrand
Let QEMU propagate the cpu state to kvm. If kvm doesn't yet support it, it is silently ignored as kvm will still handle the cpu state itself in that case. The state is not synced back, thus kvm won't have a chance to actively modify the cpu state. To do so, control has to be given back to QEMU (which is already done so in all relevant cases). Setting of the cpu state can fail either because kvm doesn't support the interface yet, or because the state is invalid/not supported.

2014-10-10s390x/kvm: proper use of the cpu states OPERATING and STOPPEDDavid Hildenbrand
This patch makes sure that halting a cpu and stopping a cpu are two different things. Stopping a cpu will also set the cpu halted - this is needed for common infrastructure to work (note that the stop and stopped flag cannot be used for our purpose because they are already used by other mechanisms). A cpu can be halted ("waiting") when it is operating. If interrupts are disabled, this is called a "disabled wait", as it can't be woken up anymore. A stopped cpu is treated like a "disabled wait" cpu, but in order to prepare for a proper cpu state synchronization with the kvm part, we need to track the real logical state of a cpu.

2014-10-10s390x/kvm: introduce proper states for s390 cpusDavid Hildenbrand
Until now, when a s390 cpu was stopped or halted, the number of running CPUs was tracked in a global variable. This was problematic for migration, so Jason came up with a per-cpu running state. As it turns out, we want to track the full logical state of a target vcpu, so we need real s390 cpu states. This patch is based on an initial patch by Jason Herne, but was heavily rewritten when adding the cpu states STOPPED and OPERATING. On the way we move add_del_running to cpu.c (the declaration is already in cpu.h) and modify the users where appropriate. Please note that the cpu is still set to be stopped when it is halted, which is wrong. This will be fixed in the next patch. The LOAD and CHECK-STOP state will not be used in the first step.

2014-10-09linuxboot: compute initrd loading addressPaolo Bonzini
Even though hw/i386/pc.c tries to compute a valid loading address for the initrd, close to the top of RAM, this does not take into account other data that is malloced into that memory by SeaBIOS. Luckily we can easily look at the memory map to find out how much memory is used up there. This patch places the initrd in the first four gigabytes, below the first hole (as returned by INT 15h, AX=e801h). Without this patch: [ 0.000000] init_memory_mapping: [mem 0x07000000-0x07fdffff] [ 0.000000] RAMDISK: [mem 0x0710a000-0x07fd7fff] With this patch: [ 0.000000] init_memory_mapping: [mem 0x07000000-0x07fdffff] [ 0.000000] RAMDISK: [mem 0x07112000-0x07fdffff] So linuxboot is able to use the 64k that were added as padding for QEMU <= 2.1.
