2014-06-19virtio-net: announce self by guestJason Wang
It's hard to track all mac addresses and their configurations (e.g vlan or ipv6) in qemu. Without this information, it's impossible to build proper garp packet after migration. The only possible solution to this is let guest (who knows all configurations) to do this. So, this patch introduces a new readonly config status bit of virtio-net, VIRTIO_NET_S_ANNOUNCE which is used to notify guest to announce presence of its link through config update interrupt.When guest has done the announcement, it should ack the notification through VIRTIO_NET_CTRL_ANNOUNCE_ACK cmd. This feature is negotiated by a new feature bit VIRTIO_NET_F_ANNOUNCE (which has already been supported by Linux guest). During load, a counter of announcing rounds is set so that after the vm is running it can trigger rounds of config interrupts to notify the guest to build and send the correct garps.

2014-06-16spapr_pci: Advertise MSI quotaBadari Pulavarty
Hotplug of multiple disks fails due to MSI vector quota check. Number of MSI vectors default to 8 allowing only 4 devices. This happens on RHEL6.5 guest. RHEL7 and SLES11 guests fallback to INTX. One way to workaround the issue is to increase total MSIs, so that MSI quota check allows us to hotplug multiple disks. This sets the quota to the maximum number of interupts XICS has which is 1024 now (XICS_IRQS). This moves XICS_IRQS from spapr.c to xics.h for wider visibility.

2014-06-16spapr_iommu: Get rid of window_size in sPAPRTCETableAlexey Kardashevskiy
This removes window_size as it is basically a copy of nb_table shifted by SPAPR_TCE_PAGE_SHIFT. As new dynamic DMA windows are going to support windows as big as the entire RAM and this number will be bigger that 32 capacity, we will have to do something about @window_size anyway and removal seems to be the right way to go.

At the moment sPAPRPHBState contains a @tcet pointer to the only TCE table. However sPAPR spec allows having more than one DMA window. Since the TCE object is already a child of SPAPR PHB object, there is no need to keep an additional pointer to it in sPAPRPHBState so remove it. This changes the way sPAPRPHBState::reset performs reset of sPAPRTCETable objects. This changes the default DMA window properties calculation.

2014-06-16spapr_pci: spapr_iommu: Make DMA window a subregionAlexey Kardashevskiy
Currently the default DMA window is represented by a single MemoryRegion. However there can be more than just one window so we need a "root" memory region to be separated from the actual DMA window(s). This introduces a "root" IOMMU memory region and adds a subregion for the default DMA 32bit window. Following patches will add other subregion(s). This initializes a default DMA window subregion size to the guest RAM size as this window can be switched into "bypass" mode which implements direct DMA mapping.

2014-06-16macio ide: Do remainder access asynchronouslyAlexander Graf
The macio IDE controller has some pretty nasty magic in its implementation to allow for unaligned sector accesses. We used to handle these accesses synchronously inside the IO callback handler. However, the block infrastructure changed below our feet and now it's impossible to call a synchronous block read/write from the aio callback handler of a previous block access. Work around that limitation by making the unaligned handling bits also go through our asynchronous handler. This fixes booting Mac OS X for me.

2014-06-16spapr: Add ibm, client-architecture-support callAlexey Kardashevskiy
The PAPR+ specification defines a ibm,client-architecture-support (CAS) RTAS call which purpose is to provide a negotiation mechanism for the guest and the hypervisor to work out the best compatibility parameters. During the negotiation process, the guest provides an array of various options and capabilities which it supports, the hypervisor adjusts the device tree and (optionally) reboots the guest. At the moment the Linux guest calls CAS method at early boot so SLOF gets called. SLOF allocates a memory buffer for the device tree changes and calls a custom KVMPPC_H_CAS hypercall. QEMU parses the options, composes a diff for the device tree, copies it to the buffer provided by SLOF and returns to SLOF. SLOF updates the device tree and returns control to the guest kernel. Only then the Linux guest parses the device tree so it is possible to avoid unnecessary reboot in most cases. The device tree diff is a header with an update format version (defined as 1 in this patch) followed by a device tree with the properties which require update. If QEMU detects that it has to reboot the guest, it silently does so as the guest expects reboot to happen because this is usual pHyp firmware behavior. This defines custom KVMPPC_H_CAS hypercall. The current SLOF already has support for it. This implements stub which returns very basic tree (root node, no properties) to the guest. As the return buffer does not contain any change, no change in behavior is expected. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-06-16spapr: Add support for time base offset migrationAlexey Kardashevskiy
This allows guests to have a different timebase origin from the host. This is needed for migration, where a guest can migrate from one host to another and the two hosts might have a different timebase origin. However, the timebase seen by the guest must not go backwards, and should go forwards only by a small amount corresponding to the time taken for the migration. This is only supported for recent POWER hardware which has the TBU40 (timebase upper 40 bits) register. That includes POWER6, 7, 8 but not 970. This adds kvm_access_one_reg() to access a special register which is not in env->spr. This requires kvm_set_one_reg/kvm_get_one_reg patch. The feature must be present in the host kernel. This bumps vmstate_spapr::version_id and enables new vmstate_ppc_timebase only for it. Since the vmstate_spapr::minimum_version_id remains unchanged, migration from older QEMU is supported but without vmstate_ppc_timebase.
